708 Technical Specifications

1.0 Standardized Documentation for First-Class Mail, Periodicals, Standard Mail, and Flat-Size Bound Printed Matter

1.1 Basic Standards

For First-Class Mail, Periodicals, Standard Mail, and Bound Printed Matter, documentation to support mail volume and preparation must be produced by standardized documentation according to this section. Standardized documentation contains the elements described in 1.2 through 1.8, as applicable. Documentation produced by Presort Accuracy Validation and Evaluation (PAVE)-certified or Manifest Analysis and Certification (MAC)-certified software is considered standardized documentation.

1.2 Format and Content

For First-Class Mail, Periodicals, Standard Mail, and Bound Printed Matter, standardized documentation includes:

a. A heading identifying the listing as a "USPS Qualification Report" appearing at the top of each page. The heading must contain these elements:

1. For First-Class Mail and Standard Mail, the name of the mailer and the mailing, a mailing identification code corresponding to the postage statement, the date when the list was processed or the documentation was produced, the class of mail, and either the DMM standard under which the mail was prepared (e.g., 245.7.0 for Standard Mail automation letters) or the type of prices claimed.

2. For Periodicals, each publication number and title corresponding to the postage statement and entry office, the date when the list was processed or the documentation was produced, the class of mail, and either the DMM standard under which the mail was prepared (e.g., 707.24.0 for letter-size barcoded Periodicals) or the type of prices claimed. For publications that are combined or copalletized and represented on the same documentation, list all publication titles and numbers in the header on the first page.

b. Sequential page numbers.

c. For mail in trays or sacks, list these required elements:

1. Tray/sack sortation level. Note with an asterisk ("*") all trays containing overflow mail moved into that tray under 235.6.6, 245.5.3 or 245.7.5.

2. Tray/sack destination ZIP Code from top line of tray/sack label except that, for 3-digit carrier routes trays, list the individual 5-digit ZIP Codes in each tray.

3. The number of pieces for each 5-digit ZIP Code in 5-digit/scheme bundles or trays; for each 3-digit ZIP Code in 3-digit/scheme bundles or trays; for each 3-digit/scheme in (A)ADC bundles or trays; for each (A)ADC in mixed (A)ADC bundles or trays (or, for Periodicals, origin mixed ADC trays). Exception: documentation for 3-digit/scheme letters in AADC trays or for AADC letters in mixed AADC trays is not required unless those trays contain overflow mail. For automation letter mailings, the number of pieces in the next higher level tray in lieu of overflow trays if applicable. For ECR letters prepared under 245.6.0, the number of pieces in carrier routes within full trays. For bundled mail, the number of pieces in each bundle level and presort destination.

4. Separate columns with the number of pieces for each price reported in the mailing, and a continuous running total of pieces for each mailing (group information either in ZIP Code order and by sortation level or by sortation level and within each sortation level, by ZIP Code; report trays and sacks on pallets by pallet level and destination; include all information required in 1.2c. for mail in trays or sacks). For pieces prepared in 5-digit scheme bundles, list by 5-digit ZIP Code within each bundle. For pieces prepared in 3-digit scheme bundles, list by 3-digit ZIP Code within the bundle. Periodicals firm bundles may be listed in a separate firm bundle column or in the appropriate column based on container level.

5. The tray identification number and size (1-foot or 2-foot) if available for letter mail in trays. The tray identification number is optional for tray-based automation flats.

6. For all Periodicals mailings, include a separate "Zone" column. If all automation letters for a specific tray, group, or bundle destination are subject to the same zone price or entry discount, show the applicable zone or destination entry discount for those copies using the zone abbreviations in 1.6.3. If automation letters for a bundle or tray destination are for multiple zones, show all zones included (e.g., "3/4/6") or show "Mixed" (or the authorized abbreviation "M") in the "Zone" column.

7. For Periodicals mailings that contain both In-County and Outside-County pieces, the listing may include a separate "Container Charge" and "Bundle Charge" column. Indicate which trays, sacks, and bundles are subject to the container or bundle charges and a total or a running total.

d. For bundles on pallets, list these required elements:

1. Pallet sortation level.

2. Pallet destination ZIP Code.

3. For each bundle, the sortation level and number of pieces claimed at each price. Periodicals firm bundles may be listed in a separate firm bundle column or in a column based on container level.

4. Separate columns with the number of pieces for each price reported in the mailing, and a continuous running total of pieces (group information either in ZIP Code order and by sortation level or by sortation level and within each sortation level, by ZIP Code). Document SCF, ADC, or NDC pallets created as a result of bundle reallocation under 705.8.11, 705.8.12, or 705.8.13 by designating the protected pallet with an identifier of "PSCF" (for an SCF pallet), "PADC" (for an ADC pallet), or "PBMC" (for a NDC pallet). These identifiers are required to appear only on the USPS Qualification Report; they are not required on pallet labels or on any other documentation.

5. For mailings of bundles on pallets under 705.12.0 and 705.13.0, provide a separate 5% threshold summary for each logical merged 5-digit scheme pallet and each logical merged 5-digit pallet.

6. For all Periodicals mailings, include a separate "Zone" column. If all copies for a bundle destination are subject to the same zone price or entry discount, show the zone or entry discount for those copies using the abbreviations in 707.17.6.3. If copies for a bundle destination are for multiple zones, show all zones included (e.g., "3/4/6") or show "Mixed" (or "M") in the "Zone" column. Report foreign copies separately.

7. For Periodicals mailings that contain both In-County and Outside-County pieces, the listing may include separate "Container Charge" and "Bundle Charge" columns. Indicate which pallets and bundles are subject to the container or bundle charges and a total or a running total.

8. At the end, a summary report of the number of pieces claimed at each price on each pallet by postage payment method, and the number of pieces and the weight of the mail on each pallet.

e. At the end of the documentation, a summary report of the number of pieces mailed at each price for each mailing by postage payment method (and by entry point for drop shipment mailings) and the number of pieces in each mailing. This information must match the information reported on the postage statement(s). For Periodicals mailings, documentation also must provide:

1. A summary of the number of each type of bundle in the mailing and, optionally, the total bundle charge paid. Report only bundles subject to the Outside-County bundle prices under 707.1.1.3.

2. A summary of the number of each type of container in the mailing and, optionally, the total container charge paid. Report only trays, sacks, and pallets subject to the Outside-County container prices under 707.1.1.4.

3. For combined mailings, a summary by mailer of the number of each type of bundle and container in the mailing and, optionally, the bundle and container price paid. Report only bundles, trays, sacks, and pallets subject to the Outside-County bundle and container prices.

4. A summary of the number of copies for each zone, including In-County, DDU, SCF, and ADC prices. A separate summary report is not required if a PAVE-certified postage statement facsimile generated by the presort software used to prepare the documentation is presented for each mailing.

c. For large-volume mailing jobs reported on a single listing, the mailer may provide abbreviated documentation that shows full bundle detail for the first 20 pallets/sacks and every twentieth pallet/sack after that. Mailers must maintain full bundle detail (by product or edition code and price) for the entire mailing job for 90 days and provide it to the USPS on request within 3 working days. This documentation must include the price summary by product or edition for each pallet/sack, including those for which full detail bundle listings are not reported.

1.6 Detailed Zone Listing for Periodicals

1.6.1 Definition and Retention

The publisher must be able to present documentation to support the number of copies of each edition of an issue, by entry point, mailed to each zone, and at DDU, DSCF, DADC, DNDC, and In-County prices. This listing is separate from the standardized documentation required to support presort and may be submitted with each mailing, or a publisher may keep these records for 2 months after the mailing date. A publisher must be able to submit detailed zone listings for specific mailings upon request by the USPS.

1.6.2 Characteristics

Report the number of copies mailed to each 3-digit ZIP Code area using either one of the following formats:

a. Report copies by each 3-digit ZIP Code in ascending numeric order. Include columns for: 3-digit ZIP Code, zone, and number of copies per zone. Include a summary of the number of copies at each zone price at the end of the report. A 3-digit ZIP Code may appear more than once if there are copies at different zone prices (e.g., In-County and Outside-County copies) for that 3-digit ZIP Code.

b. Report copies by each zone and by 3-digit ZIP Code in ascending numeric order. For each zone, include columns for: 3-digit ZIP Code and number of copies. Include a summary of the total number of copies for each zone at the end of each zone listing. A 3-digit ZIP Code may appear under more than one zone if there are copies at different zone prices for that 3-digit ZIP Code.

1.6.3 Zone Abbreviations

Use the actual price name or the authorized zone abbreviation in the listings in 1.0 and 707.17.6.2:

Zone Abbreviation	Rate Equivalent

2.0 Presort Accuracy Validation and Evaluation (PAVE)

2.1 Presort Accuracy Validation and Evaluation (PAVE)

2.1.1 Basic Information

The Presort Accuracy Validation and Evaluation (PAVE) program is a process to evaluate presort software and determine its accuracy in sorting address files under DMM standards. PAVE is available only to software and hardware manufacturers (i.e., companies that develop presort software or manufacture presorting equipment). PAVE certification does not guarantee acceptance of customer mail prepared with PAVE-validated hardware/software.

2.1.2 Process

PAVE evaluates the accuracy of presort products by providing test address files to vendors. Vendors process the test file(s) through their presort software or hardware and return the resulting postage statement facsimile(s) and other presort documentation to the USPS National Customer Support Center (NCSC) for evaluation of the answers. Each test file is evaluated for its accuracy of presort, compliance with current DMM standards, accuracy of sack/tray/pallet tag labels, and general acceptability of computer-generated facsimiles of postage statements and other presort documentation. If the answers are accurate, the vendor's presort product is validated for a 12-month period or until the end of the current annual period.

2.1.3 Participation

For information on participation in PAVE, presort product developers may request the PAVE Program Technical Guide from the NCSC by calling 1-800-238-3150. Participants may use the PAVE form included in that guide to order PAVE test files.

3.0 Coding Accuracy Support System (CASS)

3.1 Basic Information

3.1.1 Purpose

The Coding Accuracy Support System (CASS) improves the accuracy of delivery point codes, ZIP+4 codes, 5-digit ZIP Codes, and carrier route codes on mailpieces. CASS provides a common platform to measure the quality of address matching software and to diagnose and correct software problems.

3.1.2 Requirement

Any mailing claimed at an automation price must be produced from address lists properly matched and coded with CASS-certified address matching methods listed below. A mailer using multiline optical character readers (MLOCRs) to print delivery point barcodes on mailpieces must also obtain CASS certification (including Multiline Accuracy Support System (MASS)) for the address matching software used on the MLOCRs.

3.1.3 Methods

Delivery point or ZIP+4 coding may be obtained by using the CASS-certified DPC address matching software with components DPV and LACSLink; CASS-certified Z4CHANGE process; CASS-certified DirectDPV process; NCOALink; or DSF2 process.

3.2 Software Certification

3.2.1 General

Any user of address matching software that applies ZIP+4 codes to address lists to obtain an automation price must use address matching software that is CASS-certified. Address matching software used to ZIP+4 code address records must, as part of its process, return a standardized address to ensure that the ZIP+4 code or mailer-applied barcode represents the proper depth of code available. The original input address submitted for coding may also be returned. The CASS-certified address matching software must be used according to specific parameter settings (configurations) as described below.

3.2.2 Software Configuration

All address lists used to produce mailings for automation prices must be matched and ZIP+4 coded with current CASS-certified software in line with the configuration standards shown below. Summary output reports or computer-generated facsimile Forms 3553 must contain information about the configuration used when processing the address list on the CASS-certified address matching software.

3.2.3 Permissible Configurations

These are permissible configurations for address matching software:

a. Vendor-Supplied Software With Vendor CASS-certified Software Configurations. The software vendor is CASS-certified for specific configurations. The user is using that software as prescribed by the vendor and with the CASS-certified configurations obtained by the vendor.

b. Vendor-Supplied Software With User CASS-certified Software Configurations. The software user is using vendor-supplied software in a configuration not CASS-certified by the vendor but by the user.

c. User-Developed Software for Which User Obtained CASS Certification. The software user obtained individual user CASS certification for self-developed software and is using it as certified.

3.2.4 Use

When used for ZIP+4 or delivery point barcoding, the address matching software and coding methods must have a valid CASS certification and use the current USPS ZIP+4 Product updated to include all applicable change transaction files.

3.3 Date of Address Matching and Coding

3.3.1 Update Standards

Unless Z4CHANGE or DirectDPV is used, all automation and carrier route mailings bearing addresses coded by any AIS product must be coded with current CASS-certified software and the current USPS database. Coding must be done within 90 days before the mailing date for all carrier route mailings and within 180 days before the mailing date for all non-carrier route automation price mailings. All AIS products may be used immediately on release. New product releases must be included in address matching systems no later than 45 days after the release date. The overlap in dates for product use allows mailers adequate time to install the new data files and test their systems. Mailers are expected to update their systems with the latest data files as soon as practicable and need not wait until the "last permissible use" date. The mailer's signature on the postage statement certifies that this standard has been met when the corresponding mail is presented to the USPS. The "current USPS database" product cycle is defined by the following table.

File Release Use of file released on...	Required Use Must begin no later than...	Last Permissible USe And must end no later than...
February 15	April 1	May 31
April 15	June 1	July 31
June 15	August 1	September 30
August 15	October 1	November 30
October 15	December 1	January 31
December 15	February 1	March 31

3.3.2 Z4CHANGE List Matching

When using Z4CHANGE to match and code address lists for automation price mailings:

a. The entire address list must first be matched and ZIP+4 coded with current CASS-certified software and the current USPS ZIP+4 Product.

b. Every 60 days after the first matching, the address list must be processed through Z4CHANGE using USPS-certified software to identify changed records since the last update.

c. The changed records identified through the Z4CHANGE processing must then be matched and coded using current CASS-certified address matching software and the current ZIP+4 Product.

d. The entire address list must be rematched and ZIP+4 coded every 3 years using current CASS-certified software and the current USPS ZIP+4 Product.

3.3.3 DirectDPV List Matching

When using DirectDPV to match and code address lists for automation price mailings:

a. The entire address list must first be matched and ZIP+4 coded with Cycle L (or later) CASS-certified software and the current USPS ZIP+4 product.

b. Every 180 days after the initial matching, the address list must be processed through DirectDPV using Cycle L (or later) CASS-certified address matching software to identify changed records since the last update.

c. If an address record was previously ZIP+4 coded and that ZIP+4 code is not in DirectDPV, it does not need to be run through CASS-certified address matching software until the annual run. Address records identified as changed through DirectDPV that have a valid converted 11-digit record require additional processing. These records can either be reconstructed using the 11-digit code provided or reprocessed through CASS-certified software. Address records identified as changed through DirectDPV that have a zero 11-digit code must then be matched and coded using Cycle L (or later) CASS-certified address matching software and the current USPS ZIP+4 product.

d. The entire address list must be processed once a year using current CASS-certified address matching software and the current USPS ZIP+4 product.

3.4 Definitions—Mailing and Address Lists

For this section, mailing list or address list is the group of names and addresses to which mailpieces in the corresponding mailing are addressed. Whether the addresses used in a mailing are obtained from a single list or from two or more lists (whole lists or extracts of those lists), each list used to produce a mailing claimed at an automation price must meet the standards in 3.0.

3.5 Documentation

3.5.1 Form 3553

Unless excepted by standard, the mailer must complete a Form 3553 for each mailing claimed at all automation prices and all carrier route prices. A computer-generated facsimile may be used if it contains the required data elements in a format similar to the USPS form. The data recorded on Form 3553 must refer only to the address list used to produce the mailing with which it is presented. The postage statement must be annotated in the block(s) provided to reflect the date when address matching and coding were performed. When a mailing is produced using multiple lists, the mailer must show the earliest (oldest) date of address matching and coding (shown on Form 3553, section B2). The mailer certifies compliance with this standard when signing the corresponding postage statement.

3.5.2 Retention Period

Form 3553 and other documentation must be retained by the mailer or the mailer's agent for 1 year from the date of mailing and be made available to the USPS on 24-hour notice.

3.5.3 Using Output Information

The data recorded on Form 3553 is taken from the summary output report generated by the computer process by which address lists are matched and ZIP+4 coded using CASS-certified software. The summary output information may also be generated as a facsimile Form 3553. Form 3553 may show summary output information for a single address list or consolidate summary output information from multiple address lists combined to produce a single mailing. Figures on Form 3553 are not required to match total mailpiece figures on the corresponding postage statement.

3.5.4 Providing Required Data

Summary output reports or computer-generated Forms 3553 must contain this information:

a. CASS-certified company name as it appears on the CASS certificate; name and software version that received CASS certification; and the software configuration used when processing the address list.

b. Name of the list processor using the CASS-certified software to match and code the address list, the date the address list was processed, the date of the USPS database used to code the address list, the address list name or identification number, the total number of address records on the list submitted for coding, the total number of address records successfully coded to the appropriate depth of code, and the valid dates for the records successfully coded.

3.5.5 Using a Single List

When a mailing is produced using all or part of a single address list, the mailer must retain one Form 3553 and other required documentation reflecting the summary output information for the entire list, as obtained when the list was coded. When the same address list is used for other mailings within 180 days of the date it was matched and coded, a copy of the Form 3553 must be retained with the documentation for each mailing.

3.5.6 Using Multiple Lists

When a mailing is produced using multiple address lists, the mailer must retain a consolidated Form 3553 summarizing the individual summary output and/or facsimile Forms 3553 for each list used (and other required documentation). As an alternative, the mailer may combine the addresses selected from the multiple lists into a single new list, reprocess the addresses using CASS-certified address matching software, and retain one Form 3553 for the summary output generated by that process.

3.5.7 Using CASS Certificate

If the name of the CASS-certified company entered on Form 3553 does not appear on the list published by the USPS, a copy of the CASS certificate for the software used also must be retained by the mailer with the documentation.

3.6 CASS Certification

3.6.1 Testing Arrangements

To obtain information on standards and arrange for testing of carrier route, ZIP+4, or delivery point address matching software, contact the National Customer Support Center by calling 1-800-238-3150, or by writing to the CASS Certification Department, National Customer Support Center (see 608.8.0 for address).

3.6.2 CASS Stage I

The CASS certification process is a two-stage procedure. Stage I is a test file with answers supplied on request to customers wanting to certify an address matching software product. The Stage I file contains fabricated sample addresses from address ranges across the country with missing or incorrect address elements. The correct answers supplied on this Stage I test file allow self-assessment of address matching software/hardware accuracy so that software/hardware vendors or users can predetermine product readiness for the actual test.

3.6.3 CASS Stage II

The Stage II file is the actual test without answers. This test measures the accuracy of address matching software/hardware. Similar to the Stage I file, the Stage II file contains fabricated sample addresses from address ranges across the country with missing or incorrect address elements that the address matching software must correct. Software vendors or users process the Stage II file against their address matching products, appending the correct or missing information in each address record. After completing the test, the vendor or user returns the Stage II file to the USPS for analysis, scoring, and, if qualified, certification. For multiline optical character readers (MLOCRs) and encoding stations, CASS certification is obtained by barcoding sample mailpieces in a test deck. After completing the test, the vendor or user returns the test deck to the USPS for analysis, scoring, and, if qualified, certification.

3.6.4 Certification Standards

To be CASS-certified:

a. Delivery point code address matching software/hardware must correctly ZIP+4 code the addresses in the Stage II file or test deck with an accuracy rate determined by the CASS Certification Department and must correctly append the additional two digits of the delivery point code (plus a check digit) to the Stage II file or test deck with 100% accuracy.

b. A 2-digit utility (separate or stand-alone address matching software that appends only the correct 2-digit DP9019C information) must use the standardized address information returned by DPC address matching software when determining the correct delivery point code. A 2-digit utility must assign the 2-digit delivery point code (plus a check digit) to the addresses in the Stage II file with 100% accuracy.

c. Address matching software used to assign 5-digit ZIP Codes and carrier route codes must assign the appropriate codes to the Stage II file with an accuracy rate determined by the CASS Certification Department.

3.6.5 Customer Notification

The USPS sends written notice informing the customer of the results of the analysis and the product certification status. Follow-up notification is mailed to remind previously certified vendors and users of the next certification.

4.0 Standards for POSTNET and Intelligent Mail Barcodes

4.1 General

POSTNET (Postal Numeric Encoding Technique) and Intelligent Mail barcodes are USPS-developed methods to encode ZIP Code information on mail that can be read for sorting by automated machines. Intelligent Mail barcodes also encode other tracking information.

4.2 POSTNET Barcode

4.2.1 General

POSTNET (Postal Numeric Encoding Technique) is the USPS-developed barcode method to encode ZIP Code information on mail that can be read for sorting by automated machines. A POSTNET barcode can represent a 5-digit ZIP Code (32 bars), a 9-digit ZIP+4 code (52 bars), or an 11-digit delivery point code (62 bars). The information content of the barcode is based on the combination of tall (full) bars and short (half) bars. A tall bar represents "1," and a short bar represents "0." When separated into groups of five, these bars sequentially represent each of the digits of the ZIP Code (or ZIP+4 code or delivery point code) for the delivery address, plus an additional digit designated as the correction digit. The correction digit is derived from adding the numbers in the ZIP Code (or ZIP+4 or delivery point code) and determining which single-digit number must be added to that sum to make the total a multiple of 10. The first and last bars of the barcode are frame bars and must always be full bars.

4.2.2 5-Digit Barcode

A 5-digit barcode is a single field of 32 bars consisting of a frame bar, a series of 25 bars that represent the correct 5-digit ZIP Code for the address on the piece, 5 bars that represent the correction digit, and a final frame bar.

4.2.3 ZIP+4 Barcode

A ZIP+4 barcode is a single field of 52 bars consisting of a frame bar, a series of 45 bars that represent the correct ZIP+4 code for the address on the piece, 5 bars that represent the correction digit, and a final frame bar.

4.2.4 Delivery Point Barcode

A delivery point barcode (DPBC) is formed by adding 10 bars (representing two additional digits) to the ZIP+4 barcode. The correct DPBC must be derived from a CASS-certified delivery point code address matching process. To obtain information on the rules for delivery point code calculation, contact the National Customer Support Center by calling (toll-free) 1-800-642-2914, or by writing to CASS/ZIP+4 Matching, National Customer Support Center (see 608.8.0 for address). The following unique codes are also valid DPBCs:

a. For a firm (unique) 5-digit ZIP Code, the correct DPBC represents the 5-digit ZIP Code: either the USPS-assigned -0001 or (if the customer assigns four-digit add-ons to internal separations) the correct four digits applicable to the point of delivery, followed by the last two digits of the primary street number, Post Office box number, or rural/highway contract route box number derived from the standardized address returned by the CASS-certified ZIP+4 or delivery point code address matching process.

b. For an individual (unique) ZIP+4 code assigned to a business customer, the correct DPBC represents the ZIP+4 code followed by the last two digits of the primary street number derived from the standardized address returned by the CASS-certified ZIP+4 or delivery point address matching process.

4.2.5 POSTNET Barcode Dimensions and Spacing

POSTNET barcodes are subject to these standards for bar dimensions and spacing. Extraneous ink or ink voids must not cause any bar to fail to meet these standards:

a. A full bar must be 0.125 �0.010 inch high.

b. A half bar must be 0.050 �0.010 inch high.

c. All bars must be 0.020 �0.005 inch wide.

d. Measured over any 1/2 inch, horizontal spacing of the bars must be 22 �2 bars per inch, and pitch (a bar and a space) must average at least 0.0416 inch but no more than 0.05 inch. The clear vertical space between bars must not be less than 0.012 inch or more than 0.04 inch.

4.3 Intelligent Mail Barcodes

4.3.1 Definition

[9-8-09] An Intelligent Mail barcode is the USPS-developed barcode that mailers use to encode routing and tracking information on mail that can be read by automated mail processing equipment to sort mail and to provide tracking information to the mailers. An Intelligent Mail barcode consists of 65 vertical bars, each representing one of four possible states: full bar, ascender, tracker, and descender. These 65 bars encode a string of 31 digits, divided into two parts: a 20-digit tracking code and an 11-digit routing code (when required). The 11-digit routing code may contain a ZIP Code, a ZIP+4 code, or a delivery point code, unless required to contain a certain level of code in specific applications; no correction digit is needed within an Intelligent Mail barcode. Mailers may use Intelligent Mail barcodes as follows:

a. When used on letters for automation-price eligibility purposes, the routing code must contain a delivery point code that accurately matches the delivery address.

b. When used on flat-size pieces for automation-price eligibility purposes, the barcode must contain a delivery point routing code that accurately matches the delivery address. When flat-size pieces bear an Intelligent Mail barcode for automation price eligibility, the barcode on a piece that contains an optional endorsement line (OEL) must contain OEL coding that includes information in Exhibit 7.1.1 corresponding to the correct sortation level of each bundle. The OEL information in the Intelligent Mail barcode is required in addition to a physical OEL. See the Intelligent Mail Barcode Resource Guide available at http://ribbs.usps.gov/ for more information on incorporating OELs in Intelligent Mail barcodes.

c. Reply mail pieces using origin Confirm Service do not require a Mailer ID to be encoded into the Mailer Identifier field. All other mailpieces, including QBRM letters and PRM pieces as of May 2011, bearing Intelligent Mail barcodes must include the Mailer ID in the Mailer Identifier field. Confirm subscribers approved for OneCode Confirm must incorporate their Confirm Subscriber ID (which is their MID) when using Intelligent Mail barcodes. OneCode Confirm subscribers can contact Confirm Customer Assistance at 1-800-238-3150 or refer to Publication 197 for specific instructions. Mailers printing the Intelligent Mail barcode solely for automation price eligibility can contact the PostalOne! Help Desk at 1-800-522-9085 to obtain a MID.

4.3.2 Specifications

Complete specifications for Intelligent Mail barcodes are defined in USPS publication USPS-B-3200.This publication also provides details on how to encode the routing code and tracking code into an Intelligent Mail barcode, barcode dimensions and spacing, clear zone, skew and rotation tolerance, and print characteristics. The assignment of a Barcode Identifier, Service Type Identifier, and Mailer ID are described by the respective publications for each extra service. These publications are available at http://ribbs.usps.gov/.

4.4 Reflectance

4.4.1 Background Reflectance

A background reflectance of at least 50% in the red portion and 45% in the green portion of the optical spectrum must be produced in the following locations when measured with a USPS or USPS-licensed envelope reflectance meter:

a. The barcode clear zone of a card-size or a letter-size piece barcoded in the lower right corner.

b. The area surrounding the barcode (within 1/8 inch of the leftmost and rightmost bars and 1/25 inch above and below the barcode) of a card-size, letter-size, or flat-size piece barcoded in the address block and of a flat-size, First-Class Mail parcel, or Not-Flat Machinable piece barcoded elsewhere.

4.4.2 Print Reflectance Difference

A print reflectance difference (PRD) of at least 30% in the red and green portions of the optical spectrum is required between the background material of the mailpiece and the barcode, when measured with a USPS or USPS-licensed envelope reflectance meter. (PRD equals the reflectance of the background minus the reflectance of the ink.)

4.4.3 Opacity

The material on which the barcode appears must have enough opacity to prevent printing from "showing through" to the extent that it interferes with postal equipment that reads the barcode. The print contrast ratio (PCR) of print (other than the barcode) that shows through the barcode clear zone or the barcode area in the address block must not exceed 15% when measured in the red and green portions of the optical spectrum.

4.4.4 Dark Fibers and Background Patterns

Dark fibers or background patterns that produce a print contrast ratio of more than 15% when measured in the red and green portions of the optical spectrum are prohibited in these locations:

a. The area of the address block or the barcode clear zone where the barcode appears on a card-size or a letter-size piece mailed at automation prices or at Enhanced Carrier Route saturation or high density prices.

b. The area of the address block or the area of the mailpiece where the barcode appears on a flat-size piece in an automation price mailing or on a First-Class Mail parcel or a Not Flat-Machinable piece.

4.5 Skew and Baseline Shift

4.5.1 Card-Size and Letter-Size Pieces

For a barcode on a card-size or a letter-size piece, the combined effects of positional skew (slant or tilt of the entire barcode baseline) and rotational skew (slant or tilt of the individual barcode bars) must be limited to a maximum rotation of the bars of �5 degrees from a perpendicular to the bottom edge of the piece. The individual bars of a barcode must not shift (be vertically offset) more than 0.015 inch from the average baseline of the barcode. For information on barcode placement for card-size and letter-size pieces, see 202.5.0.

4.5.2 Flat-Size Pieces, First-Class Mail Parcels, Standard Mail Irregular Parcels, and Not Flat-Machinable Pieces

The maximum rotational skew (slant or tilt of the individual barcode bars) for barcodes is �10 degrees from a perpendicular to the baseline of the barcode. There is no positional skew requirement. The individual bars of a barcode must not shift (be vertically offset) more than 0.015 inch from the average baseline of the barcode. For information on barcode placement for flat-size pieces, see 302.5.0. For information on barcode placement on parcels and Not Flat-Machinable pieces weighing less than 6 ounces, see 402.4.0.

4.6 Barcode Software and Hardware Certification

4.6.1 Purpose

To help mailers evaluate the quality of their equipment producing barcodes, the USPS offers optional testing and certification to manufacturers of barcoding software and hardware. Certified barcoding equipment ensures that the equipment can produce dimensionally correct barcodes meeting postal specifications. Certification does not ensure that barcodes produced from that equipment can meet the requirements for automation prices because many other variables in barcode production (e.g., ink color and quality, paper color and contrast, equipment operation and maintenance) affect the quality of the barcodes printed on mailpieces.

4.6.2 Testing Arrangements

Manufacturers who want their products tested and mailers who want information on available certified products should contact the National Customer Support Center (see 608.8.0 for address).

5.0 Standards for Postal Routing Barcodes

5.1 Basic Requirements

Mailers may use a postal routing barcode on parcels and Not Flat-Machinable pieces that meet the applicable eligibility requirements in 433 for First-Class Mail, 443 for Standard Mail, 453 for Parcel Select, 463 for Bound Printed Matter, 473 for Media Mail, or 483 for Library Mail. Each parcel must bear a properly prepared GS1-128 barcode symbology as described in 5.2 that accurately represents the correct ZIP Code or ZIP+4 code of the delivery address. For information on barcode placement for parcels, see 402.4.0.

5.2 Basic Elements of Postal Routing Barcodes

GS1-Code128 postal routing barcode data elements include:

a. Barcode Type. GS1-128 is the only acceptable barcode and must be printed within Subset C.

b. Start Code. Postal routing barcodes must start with a Symbol Start Code, which is not shown in the human-readable text.

c. Function One (FNC1). The FNC1 numeric character for GS1-128 follows the symbol start character, is part of the symbology overhead, and is not shown in the human-readable text.

d. Application Identifier (AI). The AI for a postal routing barcode is "420" for domestic mail and is not shown in the human-readable text.

e. ZIP Code or ZIP+4 Code. Postal routing barcodes must include the 5-digit ZIP Code or ZIP+4 code of the address. Only the 5-digit ZIP Code appears in the human-readable text.

f. Check Digit. A check digit must be added at the end of the sequence of numbers to validate the authenticity of the number. GS1-128 postal routing barcodes must utilize a MOD 103 check digit, which is not shown in the human-readable text.

g. Stop Code. The GS1-128 postal routing barcode must end with a Symbol Stop Code, which is not shown in the human-readable text.

Exhibit 5.2 Postal Routing GS1-128 Barcode Format

5.3 Use With Delivery Confirmation or Signature Confirmation Service

Eligible machinable parcels may qualify for the barcode discount and bear a Delivery Confirmation or Signature Confirmation barcode using one of the following options:

a. The Single Concatenated Barcode (see Exhibit 5.3a). Mailers may place a single concatenated barcode that combines the postal routing information and Delivery Confirmation or Signature Confirmation information. Single concatenated barcodes must be prepared in accordance with the technical specifications and requirements in 503.9.0 for Delivery Confirmation service, 503.10.0 for Signature Confirmation service, and Publication 91, Confirmation Services Technical Guide. If a parcel bears a single concatenated barcode, then no other barcode that contains the postal routing barcode may be affixed to the package.

Exhibit 5.3a Confirmation Services Concatenated GS1-128 Barcode Format

b. Separate Barcodes (see Exhibit 5.3b). Mailers may place both a postal routing barcode described in 5.2 and a Delivery Confirmation barcode described in 503.9.0 or a Signature Confirmation barcode described in 503.10.0 (and Publication 91) on the same parcel.

Exhibit 5.3b Confirmation Services GS1-128 Barcode Format Using a Separate Postal Routing Barcode

5.4 Use With Confirmation Services and Insurance (Integrated Barcode)

To eliminate the need to place one barcode for Delivery Confirmation or Signature Confirmation and another barcode for insurance, eligible machinable parcels may qualify for the barcode discount by placing a single integrated barcode that combines Delivery Confirmation or Signature Confirmation and insurance using one of the following options:

a. Single Concatenated Integrated Barcode. Mailers may place a single concatenated integrated barcode that combines postal routing information and postal insurance (see 503.9.0) with Delivery Confirmation service or Signature Confirmation service. The single concatenated integrated barcode option allows electronic option mailers to combine multiple special services into a single barcode on their packages. Single concatenated integrated barcodes must be prepared in accordance with the technical specifications and requirements in 503.9.0 for Delivery Confirmation service, 503.10.0 for Signature Confirmation service, and Publication 91. If a parcel bears a single concatenated integrated barcode then no other barcode that contains the postal routing barcode may be affixed to the package.

b. Separate Barcodes. Mailers may place both a postal routing barcode described in 5.2 and an integrated barcode that combines insurance as described in 5.4a. on the same parcel with Delivery Confirmation in 503.9.0 or Signature Confirmation in 503.10.0. The integrated barcode option allows electronic mailers to combine multiple special services into a single barcode on their packages.

5.5 Dimensions

The preferred range of widths of narrow bars and spaces is 0.015 inch to 0.017 inch. The width of the narrow bars or spaces must be at least 0.013 inch but no more than 0.021 inch. All bars must be at least 0.75 inch high.

5.6 Location

The address and barcode must be placed squarely onto the largest surface area of the parcel, except when its shape and contents requires specific orientation for stability during processing; then the address and barcode(s) must be placed on the top. The address and barcode label(s) must not overlap any side of the parcel or other label. The barcode should be placed immediately adjacent to the delivery address and at least 1 inch from the edge of the parcel. The delivery address and barcode may be printed on an attachment or enclosure in a window envelope affixed to the parcel, subject to the reflectance standards in 4.4. The barcode may be placed on a separate label or in an alternate location on the address label, subject to the clearance standards in 5.7. Barcodes that are not placed immediately adjacent to the delivery address must not encroach the return address, postage, applicable markings, endorsements, and extra service labels.

5.7 Clear Zone

The barcode must be located as specified in 5.6. No printing may appear in an area 1/8 inch above and below the barcode. A minimum clear (quiet) zone equal to 10 times the average measured narrow element (bars or space) width must be maintained to the left and right of the barcode.

5.8 Reflectance

When measured in the red spectral range between 630 nanometers and 675 nanometers, the minimum white bar (space) reflectance (Rs) must be greater than 50%, and the maximum bar reflectance (Rb) must be less than 25%. The minimum print reflectance difference (Rs-Rb) is 40%. Reflectance must be measured with a USPS-specified reflectance meter or barcode verifier.

5.9 Quality

All barcodes in each mailing must measure American National Standards Institute (ANSI) grade C or above. ANSI grade barcodes D or F are unacceptable. It is strongly recommended that all printing processes be tested to ensure that they meet specification requirements. Information concerning ANSI guidelines X3.182-1990 may be obtained from the American National Standards Institute (see 608.8.0).

5.10 Human-Readable Information

The human-readable information on the barcode must conform to one of the following options:

a. For postal routing barcodes printed under 5.2, 5.3b., and 5.4b., if the postal routing barcode is printed on a separate label, the human-readable equivalent of the ZIP Code or ZIP+4 code encoded in the barcode preceded by the word "ZIP" must be printed between 1/8 inch and 1/2 inch below the barcode in 10-point or larger bold sans-serif type. Alternatively, the word "ZIP" may be placed no less than 10 times the average narrow bar or space element width and no more than 1/2 inch to the left of the barcode, in 10-point or larger bold sans-serif type (see Exhibit 5.2). While not recommended, if the postal routing barcode is printed on the delivery address label and is in close proximity to the address, the human-readable equivalent of the ZIP Code (and the word "ZIP") may be omitted.

b. For barcodes printed under 5.3b. or 5.4b. the human-readable information for the concatenated or concatenated/integrated barcode must include as text the application identifiers (AI) 420 and 91 and the full tracking identification number. When the AI 420 and ZIP Code information is used, it must be parsed separately from the main body of text. The first group will contain the 420 AI, space, 5-digit ZIP Code, space, +4 code (if used), space, with the remaining human-readable text parsed in groups of four with the remaining digits grouped at the end (e.g., 420 22021 9122 1234 5678 9123 4567 83).

5.11 Technical Specifications

Postal routing codes must meet the technical specifications in the GS1-128 Application Identifier Standard, which can be obtained from Uniform Code Council Inc. (see 608.8.0), and the barcode characteristics in 5.0.

5.12 Substrate Material

Barcodes must be printed on substrate material that preserves the optical specification as described in the AIM-USA Uniform Symbology Specification documents. Typically, white label stock commonly used for barcode generation is suitable, providing it is not glossy (causing mirror-like, specular reflection) or prone to smearing or smudging.

6.0 Standards for Barcoded Tray Labels, Sack Labels, and Container Placards

6.1 General

6.1.1 Tray and Sack Labels

Intelligent Mail tray labels (see 6.5), barcoded 2-inch tray and sack labels, and barcoded 1-inch sack labels are the USPS-approved methods to encode routing, content, origin, and mailer information on trays and sacks. Intelligent Mail tray labels are designed for use with Intelligent Mail barcoded mail and have the capacity to provide unique identification throughout postal processing.

6.1.2 Container Placards

Mailer-generated container placards bearing Intelligent Mail container barcodes identify the mail owner or agent and uniquely identify the unit (pallet, container, or rolling stock). Intelligent Mail container placards are designed for use with Intelligent Mail barcoded mail and Intelligent Mail tray labels.

6.2 Specifications for Barcoded Tray and Sack Labels

6.2.1 Use

Exhibit 6.2.1 shows the types of mail requiring barcoded tray or sack labels. Barcoded labels must meet these general standards:

a. Mailers must use the appropriate size label for the sack or tray.

b. Mailer-produced barcoded labels must meet the standards in 6.0.

c. All information on barcoded labels must be machine-printed. Alterations to preprinted barcoded labels (e.g., handwritten changes) may not be made.

d. Barcoded labels must be inserted completely into the label holder on the tray or sack to prevent their loss during transport and processing.

6.2.2 Line 1 (Destination Line)

The destination line must meet these standards:

a. Placement. The destination line must be the top line of the label, placed in the position shown in Exhibit 6.2.2a or Exhibit 6.2.2b (above the barcode on tray labels or 2-inch sack labels and to the right of the barcode on 1-inch sack labels). An exception is that one line of extraneous information may appear above the destination line on tray and sack labels as provided in 6.3.2, and 6.3.2f. The destination line must be completely visible when placed in the label holder. This visibility is ensured if the destination line is no less than 1/8 (0.125) inch below the top of the label when the label is cut and prepared.

Exhibit 6.2.2a Barcoded 2-Inch Sack Labels and Barcoded Tray Labels

b. Information. The destination line must contain only the information required by the applicable standards for the class, processing category, sortation level of the tray or sack, and the prices claimed. This information is contained in the labeling lists for all sortation and price levels except trays and sacks to carrier route, 5-digit carrier routes, merged 5-digit, and 5-digit destinations, and except for automation letter trays to 5-digit scheme destinations. For the destination line of carrier route, 5-digit carrier routes, merged 5-digit, and 5-digit trays and sacks, the city, two-letter state abbreviation, and 5-digit ZIP Code of the destination 5-digit ZIP Code area must be shown. For 5-digit scheme trays, the city, two-letter state abbreviation, and ZIP Code for the destination scheme must be obtained from the City State Product. The destination line may contain abbreviated city and state information if such abbreviations are those in the City State Product.

Exhibit 6.2.2b Barcoded 1-Inch Sack Labels

c. Overseas Military Mail. The exact content identifier number (CIN) that matches the level of tray or sack must be used in the barcode and barcode numeric line on barcoded tray or sack labels. The required second line of information that corresponds to the CIN must appear on the human-readable content line of the label. The human-readable content line is automatically printed when labels are obtained through the PASSPORT system or ordered on Form 1578-B for printing at the Label Printing Center in Topeka, Kansas. A footnote at the end of the content line information means that the mailer must add appropriate information when ordering and printing tray and sack labels. Any mailer using PASSPORT to order labels must also add the appropriate additional information to the human-readable content line for those content lines marked with a footnote.

6.2.3 Line 2 (Content Line)

The content line must meet these standards:

a. General. The content line must appear directly below the destination line as shown in Exhibit 6.2.2a or Exhibit 6.2.2b . This line must show the class, processing category, and the sortation level of the tray or sack as required by the applicable standards for the mailing. The appropriate content identifier number (CIN) in 6.2.4 that corresponds to that content line must be used in the barcode.

b. Periodicals. Except as provided in 705.8.16 for copalletized mailings and in 707.27.2 for combined mailings, Periodicals publications must use one of the following for Line 2 class information:

1. "PER."

2. "NEWS" if published weekly or more often or if authorized newspaper treatment as of March 1, 1984.

c. Additional Information. For 3-digit scheme trays as specified by the labeling list, the content line for some destinations must be followed by the letter "A," "B," or "C," which is not required to be right-justified. For carrier route trays and sacks, the content information must be followed by a one-letter carrier route type description followed by a space and a 3-digit route number for the route to which the tray is destined.

6.2.4 3-Digit Content Identifier Numbers

The exact content identifier number (CIN) that matches the level of tray or sack must be used in the barcode and barcode numeric line on barcoded tray or sack labels. The required second line of information that corresponds to the CIN must appear on the human-readable content line of the label. The human-readable content line is automatically printed when labels are obtained through the PASSPORT system or ordered on Form 1578-B for printing at the Label Printing Center in Topeka, Kansas. A footnote at the end of the content line information means that the mailer must add appropriate information when ordering and printing tray and sack labels. Any mailer using PASSPORT to order labels must also add the appropriate additional information to the human-readable content line for those content lines marked with a footnote. See Exhibit 6.2.4 .

f. Extraneous Information Lines. Extraneous information may be printed only at the top of the label and/or at the bottom of the label. The preferred location is the bottom of the label. If placed at the bottom of the label, the information must appear only in a rectangular area that begins 1.620 inches from the top of the label and extends to the bottom of the label. Within this lower area, the information may extend 2.75 inches to the right from the left edge of the label. See Exhibit 6.3.2f. Extraneous information at the bottom of the label must appear below the barcode numeric and origin lines. There are no font restrictions for information printed in this area at the bottom of the label with one exception: if information in this area resembles a day of the week or a USPS air stop code it must be in 10-point or smaller type. Extraneous information printed at the top of the label must have a maximum character height of 0.083 inch. Barcodes for a mailer's internal use may not be placed in extraneous information areas or anywhere else on the label, unless approved on a case-by-case test basis by USPS Engineering (see 608.8.0 for address).

Exhibit 6.3.2f Extraneous Information Area

6.3.3 Barcode

The label barcode must meet these specifications:

a. Type of Barcode. The barcode must be an interleaved 2-of-5 code according to the Automatic Identification Manufacturers' Uniform Symbology Specification (AIM/USS-I 2/5) with the exceptions noted below.

b. Information. The barcode must represent three numeric elements:

2. The applicable 3-digit content identifier number (CIN) for the tray as shown in 6.2.4.

3. A 2-digit USPS processing code on all 2-inch tray labels. A processing code is optional on 2-inch sack labels. Use code "01" for all automation price and machinable letter-size pieces, and for all automation-compatible and cotrayed flat-size pieces. Use code "07" for all other mail, including manual pieces, nonmachinable letter-size pieces, and nonautomation Carrier Route price pieces.

c. Placement. The barcode must be on the left side of the tray label, below the destination and content lines. The top of the barcode must be not less than 0.6 inch from the top of the label. The bottom of the barcode must be no more than 1.5 inches from the top of the label. The barcode must not extend more than 2.0 inches to the right from the left edge of the label.

d. Quiet Zones. Two quiet zones (clear areas) must be maintained, one to the left and one to the right of the barcode, each measuring at least 10 times the X dimension (see 6.3.3f) and extending the full height of the barcode. Two additional quiet zones must be maintained, one above and one below the barcode for its full width, each measuring at least 0.070 inch. The quiet zones must meet the space reflectance specification in 6.3.3i.

e. Height. The height of the barcode must be from 0.65 to 0.75 inch.

f. X Dimension. The width of the narrow bar element and narrow space element is defined as the X dimension. It must be selected as a single dimension and it must be uniform within the barcode. The minimum X dimension or narrow element width is 0.012 inch and the maximum is 0.016 inch. The optimum X dimension or narrow bar/space width is 0.015 inch.

g. Wide-to-Narrow Bar Ratio. The wide-to-narrow ratio for bars and spaces within the barcode must be between 3 to 1 and 2.3 to 1 and uniform within the barcode. The optimum ratio is 3 to 1.

h. Printing Tolerances. The maximum irregularity in the edge straightness of any bar element is 0.3 times the X dimension. The printing tolerance for any (narrow or wide) bar or space is +0.004 inch and is not cumulative. Example 1: If an X dimension of 0.015 inch is selected, each individual narrow bar or narrow space element on the printing of the barcode must not be less than 0.011 inch or more than 0.019 inch. Example 2: If the wide bar/space dimension of 0.045 inch is selected, each individual wide bar or space must not be less than 0.041 inch or more than 0.049 inch.

i. Reflectance. When measured at 633 nanometers, bar reflectance must be less than 30% and space reflectance must be more than 40%. The bar-to-space reflectance difference must be more than 40%.

d. Length (parallel to printing): 3.250 inches minimum; 3.515 inches maximum.

6.4.2 Printed Human-Readable Lines

The printed human-readable text lines must meet these specifications:

a. General. The human-readable lines must be printed in uppercase letters, with no run-on letters or numerals. The letters and numerals in the destination, content, and origin lines must be easy to read. The character spacing can be proportional with respect to the type font used, and should not exceed 17 characters per inch. When the information cannot be shortened by acceptable postal abbreviations, it may be printed in a compressed font. The information must appear to the right of the right barcode quiet zone.

b. Destination Line (Line 1). The printed destination line must have a minimum character height of 0.083 inch. The corresponding ZIP Code must have a minimum character height of 0.111 inch. The destination line must accommodate at least 22 characters.

d. Origin Line (Line 3). The printed origin line must have a minimum character height of 0.083 inch.

e. Barcode Numeric Line. A barcode numeric line is optional. If used, the numeric line must consist of a numeric representation of the eight digits of information contained in the barcode as required by 6.4.3b (5-digit ZIP Code and CIN). The printed numeric barcode line must have a maximum character height of 0.085 inch. It must be placed a minimum of 0.070 inch below the barcode (see Exhibit 6.2.2b Barcoded 1-Inch Sack Labels).

f. Extraneous Information Lines. Extraneous information may be printed only to the right of the right quiet zone if it does not interfere with scanning and sorting by automated equipment. Extraneous information may be placed (1) below the origin line; (2) above the destination line; or (3) either between the content and origin lines or to the right of required information on the origin line, provided that the information does not consist of numerals that resemble a ZIP Code or 3-digit ZIP Code prefix. It is recommended that this information be placed below the origin line. If placed above the destination line, the maximum height of the type is 0.083 inch, and it is further recommended that the information be printed in a size of type much smaller than the size used on the destination line. Extraneous information must not be placed between the destination and content lines.

6.5 Intelligent Mail Tray Labels

6.5.1 Definition

Intelligent Mail tray labels are 2-inch labels used on trays and sacks to provide unique identification within postal processing. 24-digit Intelligent Mail tray labels include only a 24 digit barcode printed in International Symbology Specification (ISS) Code 128 subset C symbology (see Exhibit 6.5.3). To facilitate the transition from 10-digit tray and sack labels to 24-digit barcoded Intelligent Mail tray labels, an optional transitional label is also available. This label includes a 10-digit barcode using the AIM/USS-I 2/5 symbology, in addition to a 24-digit barcode using ISS Code 128 subset C symbology (see Exhibit 6.5.1). Intelligent Mail tray labels also include a human readable field designed to indicate the carrier route for carrier route mailings, display an "AUTO" indicator text for automation mailings, or remain blank for nonautomation mailings. Mailers using Intelligent Mail tray labels may print labels in the 24-digit Intelligent Mail tray label format or the transitional format. Detailed specifications for the tray label and barcode formats are at http://ribbs.usps.gov.

Exhibit 6.5.1 10/24 Transitional Intelligent Mail Tray Label

6.5.2 Transitional Intelligent Mail Tray Label Format

The general format for Intelligent Mail tray labels are as follows:

7.1.2 Intelligent Mail Barcodes

When flat-size pieces bear an Intelligent Mail barcode (under 4.3) for automation-price eligibility purposes, the barcode on a piece that contains an optional endorsement line (OEL) must contain OEL coding that includes information in Exhibit 708.7.1.1 that corresponds to the correct sortation level of each bundle. The OEL information in the Intelligent Mail barcode is required in addition to a physical OEL. See the Intelligent Mail Barcode Resource Guide available at http://ribbs.usps.gov/ for more information on incorporating OELs in Intelligent Mail barcodes.

7.1.3 Keyline

A mailer's keyline or comparable information may not be placed on the same line as the OEL or on the line above the OEL. A keyline used on valid ACS mailpieces is subject also to 7.2.4, No ACS Code in OEL.

7.1.4 Firm Bundles

On a firm bundle of carrier route presorted Periodicals, "FIRM" may precede "CAR-RT SORT" in the carrier route information line under 6.0.

7.1.5 Price Markings

At the mailer's option, price markings required by the standards for the price claimed may be included in the OEL if the OEL appears on each piece in the mailing and if it remains a single line with the basic bundle label information (required by 7.1.1) at the right end (e.g., on a carrier route bundle of Enhanced Carrier Route Saturation Standard Mail: * * * * ECRWSS**C-001; on an automation Standard Mail 3-digit bundle: * * * * AUTO**3-DIGIT 750).

7.1.6 Exceptional Address Format

The exceptional address format may appear above the OEL as specified in 602.3.0, Use of Alternative Addressing.

7.1.7 OEL With LOT Information

At the mailer's option, line-of-travel (LOT) information for carrier route Periodicals and Enhanced Carrier Route Standard Mail may be included in the OEL using the applicable format in 7.1.1. All other OEL requirements apply. If there is insufficient space within the OEL to include any other information required (e.g., ACS participant code), this OEL format may not be used.

7.2 OEL Format

7.2.1 Presort Identification

Except when an address block barcode is placed above the optional endorsement line (OEL), the appropriate presort identification must be the first line at the top of the address block or label. A mailer receiving address corrections through Address Change Service (ACS) may use the first eight positions on the left side of the OEL for an ACS human-readable participant code.

7.2.2 Style and Size of Type

The information in the OEL must be in capital letters with letter size and line spacing no less than the size and line spacing of the largest letters or characters in the address block or any part of the address label. Letters in the endorsement line must be the same type font as those in the address block. Only capital letters of the alphabet, Arabic numerals, or asterisks may be used in the OEL.

7.2.3 ACS Code in OEL

If an ACS human-readable participant code (see 507.4.2) is used in an OEL on a label or in an address block, the delimiter symbol (#) must be in the first position at the left margin of the OEL, followed by the seven-character USPS-assigned ACS participant code, then one blank space. The remaining blank spaces between the left-justified delimiter and ACS participant code and the first character of the right-justified mail sortation information of the OEL must be filled with asterisks.

7.2.4 No ACS Code in OEL

If an ACS human-readable participant code is not placed in the OEL as permitted by 507.4.2.4, the OEL must be filled with asterisks from the left margin of the label or address block up to the first character in the OEL. A keyline prepared under 7.1.3 is required on valid ACS mailpieces if an ACS participant wants to receive notification of nondelivery information under 507.1.4.1 in addition to address correction service.

7.2.5 ZIP Code Information

Except for carrier route bundles, the OEL must include the ZIP Code information (5-digit ZIP Code or 3-digit ZIP Code prefix) determined by the sortation level and, when applicable, by the labeling list designated in Exhibit 7.2.5 for ADC, mixed ADC, AADC, or mixed AADC sortation levels. Carrier route OELs must show carrier route information as specified in 8.2.

9.0 Facing Identification Mark (FIM)

9.1 Using FIMs

The facing identification mark (FIM) serves to orient and separate certain types of First-Class Mail during the facing-canceling process. Mailers must use the appropriate FIM as follows:

a. All letter-size business reply mail (BRM) under 507.9.0.

b. All letter-size permit reply mail (PRM) under 507.10.0.

c. Letter-size courtesy reply mail (CRM) and meter reply mail (MRM) provided as enclosures in automation-price mailings under 201.3.0.

d. Letter-size mail with IBI printed with nonfluorescent ink directly onto the envelope by an IBI meter or a PC postage system must use FIM D.

e. Cards and letter-size envelopes containing absentee balloting materials under 703.8.0.

f. A FIM must not be used on other types of mail, except that a FIM may be used on a letter-size envelope with a permit imprint indicia when that envelope is designed for use as a reusable mailpiece under 601.6.0. A FIM used for this purpose must be the appropriate FIM for the postage payment method on the returned envelope (see 9.2).

9.2 Pattern

[6-7-10] The FIM pattern is a nine-bit binary code represented by vertical bars (with corresponding space element). A printed bar is considered binary 1; a nonprinted bar (placeholder), binary 0. The required FIM pattern as shown in Exhibit 9.2 below depends on the type of mail and the presence of a POSTNET barcode or Intelligent Mail barcode as follows:

a. FIM A is used for CRM and MRM with a preprinted barcode. (FIM A binary code is 110010011.)

b. FIM B is used for BRM without a preprinted BRM ZIP+4 barcode. (FIM B binary code is 101101101.)

c. FIM C is used for BRM with a preprinted BRM ZIP+4 barcode and for PRM with a preprinted delivery-point barcode. (FIM C binary code is 110101011.)

d. FIM D is used for letter-size First-Class Mail with IBI printed with nonfluorescent ink directly on the envelope. (FIM D binary code is 111010111.)

e. FIM E is used for postcard-size and letter-size First-Class Mail with customized services. (FIM E binary code is 101000101.)

b. The FIM bars must be 5/8 inch (�1/8 inch) high and 1/32 inch (�0.008 inch) wide and positioned as follows:

1. The right edge of the rightmost bar of the FIM must be 2 inches (�1/8 inch) from the right edge of the piece.

2. The tops of the FIM bars must be no lower than 1/8 inch from the top edge of the piece. The tops of the bars may extend over the top edge of the piece to the back (flap) of the piece if at least a 1/2-inch bar height is maintained on the address side.

3. The bottoms of the FIM bars must touch the bottom boundary of the FIM clear zone or be no more than 1/8 inch above or below this boundary.

Exhibit 9.3 Position of FIM

[

9.4 Dimensional Tolerances

Extraneous ink must not cause a FIM bar to exceed the specifications in 9.3. The combined effects of positional skew (slant of the entire FIM) and rotational skew (slant of the individual FIM bars) must be limited to �5 degrees from the perpendicular edge of the printed FIM to the top edge of the mailpiece. Mail required to bear a FIM is considered nonmailable when the FIM has insufficient ink coverage, improper measurement, or ink in the space between the bars or when the FIM is enlarged or reduced. Camera-ready positives of FIMs, which must not be enlarged or reduced, are available at no charge from the USPS.

9.5 Reflectance

There must be at least a 30% print reflectance difference between the ink used for printing the FIM and the background material on which the FIM is printed in the red and green portions of the optical spectrum when measured with a USPS or USPS-licensed envelope reflectance meter.

10.0 Postal Zones

10.1 Basis

Postal prices for certain subclasses of mail are based on the weight of the individual piece and the distance that the piece travels from origin to destination (i.e., the number of postal zones crossed). For the administration of these postal zones, the earth is divided into units of area 30 minutes square, identical with a quarter of the area formed by the intersecting parallels of latitude and meridians of longitude. Postal zones are based on the distance between these units of area. The distance is measured from the center of the unit of area containing the SCF serving the origin Post Office to the SCF serving the destination Post Office. The SCFs serving the origin and destination Post Offices are determined by using L005, Column B.

10.2 Application

Zones are used to compute postage on zoned mail sent between USPS facilities, including military Post Offices (MPOs), as follows:

a. For the purposes of computing postal zone information, except for items 10.2b. and 10.2c., the following table applies to MPOs not listed in L005.

3-digit ZIP Code Prefix Group	SCF Serving The Destination Office
090-098	SCF New York NY 100
340	SCF Miami FL 331
962-966	SCF San Francisco CA 940

b. The postage prices for zoned mail transported between the United States, the Canal Zone, Puerto Rico, or U.S. territories or possessions, including the Trust Territory of the Pacific on the one hand, and MPOs on the other, or, among the MPOs, are the applicable zone prices for mail between the place of mailing or delivery and the city of the postmaster serving the MPO concerned.

c. The postage price for zoned mail mailed at or addressed to an MPO and transported directly to or from MPOs at Department of Defense expense, without transiting any of the 48 contiguous states (including the District of Columbia), is the applicable local zone price. If such mail transits any area served by the USPS at USPS expense and the distance from the place of mailing to the embarkation point or from the debarkation point to the place of delivery is more than the local zone for such mail, postage is assessed by the distance from the place of mailing to the embarkation point or from the debarkation point to the place of delivery of such mail, as the case may be. The word transiting does not include en route transfers at coastal gateway cities necessary to transport military mail directly between MPOs. For example, a parcel mailed at Honolulu, HI, for direct dispatch by the Department of Defense from Honolulu to an MPO in the Pacific is subject to the local zone price. A parcel mailed at Hilo, HI, and transported at USPS expense to Honolulu, HI, for direct dispatch at Department of Defense expense from Honolulu to an MPO in Japan is subject to zone 2 prices.

10.3 Zone Charts

The USPS Official National Zone Chart Data Program is administered from the National Customer Support Center (NCSC) in Memphis, TN. Single-page zone charts for originating mail are available at no cost from local Post Offices or online at pe.usps.com. Zone chart data for the entire nation can be purchased in print and CD-ROM formats. For more information or to purchase zone charts, call the Zone Chart program administrator at 800-238-3150 or write to the NCSC (see 608.8.0 for address).

10.4 Specific Zones

10.4.1 Local Zone

The local zone applies to mail deposited at any Post Office for delivery to addresses within the delivery area of that Post Office. For various types of Post Offices, the local zone applies to all mail that both originates and destinates within:

a. The 5-digit ZIP Code area(s) assigned to the same Post Office.

b. Any of the 5-digit ZIP Codes that are part of any unique 3-digit ZIP Code prefix(es) or other separate 5-digit ZIP Code(s), as applicable, assigned to the same Post Office.

10.4.2 Nonlocal Zone

Nonlocal zones are defined as follows:

a. The zone 1 price applies to pieces not eligible for the local zone in 10.4.1 that are mailed between two Post Offices with the same 3-digit ZIP Code prefix identified in L005, Column A. Zone 1 includes all units of area outside the local zone lying in whole or in part within a radius of about 50 miles from the center of the area.

b. Zone 2 includes all units of area outside zone 1 lying in whole or in part within a radius of about 150 miles from the center of a given unit of area.

c. Zone 3 includes all units of area outside zone 2 lying in whole or in part within a radius of about 300 miles from the center of a given unit of area.

d. Zone 4 includes all units of area outside zone 3 lying in whole or in part within a radius of about 600 miles from the center of a given unit of area.

e. Zone 5 includes all units of area outside zone 4 lying in whole or in part within a radius of about 1,000 miles from the center of a given unit of area.

f. Zone 6 includes all units of area outside zone 5 lying in whole or in part within a radius of about 1,400 miles from the center of a given unit of area.

g. Zone 7 includes all units of area outside zone 6 lying in whole or in part within a radius of about 1,800 miles from the center of a given unit of area.

h. Zone 8 includes all units of area outside zone 7.

10.4.3 Delivery Unit (Office)

The delivery unit price applies to mail destinating within the delivery area of the delivery unit at which it is deposited by the mailer.
