1.0 Elements of Addressing

1.1 Clear Space

A clear space must be available on all mail for the address, postage (permit imprint, postage stamp, or meter stamp), postmarks, and postal endorsements.

1.2 Delivery Address

The delivery address specifies the location to which the USPS is to deliver a mailpiece. Except for mail prepared with detached address labels under 4.0, the piece must have the address of the intended recipient, visible and legible, only on the side of the piece bearing postage.

1.3 Address Elements

All mail not bearing a simplified address must bear a delivery address that contains at least the following elements in this order from the top line:

  1. Intended recipient’s name or other identification.
  2. Private mailbox designator (“PMB” or alternative “#”) and number if the mailpiece is addressed to a commercial mail receiving agency (CMRA) address.
  3. Street and number. (Include the apartment number, or use the Post Office box number, or general delivery, or rural route or highway contract route designation and box number, as applicable.)
  4. City and state (or state abbreviation). The city is any acceptable mailing name for the 5-digit ZIP Code serving the intended recipient as shown in the USPS City State Product.
  5. ZIP Codes are required on Priority Mail Express, commercial First-Class Mail, First-Class Package Service — Commercial, Periodicals, USPS Marketing Mail, Package Services and Parcel Select mailpieces, all mail sent to military addresses within the United States and to APO and FPO addresses, official mail, Business Reply Mail, and USPS Returns service packages.
1.4 Complete Addresses
1.4.1 Complete Address Definition

A complete address has all the address elements necessary to allow an exact match with the current USPS ZIP+4 Product to obtain the finest level of ZIP+4 code for the delivery address. A complete address may be required on mail at some automation prices.

1.4.2 Complete Address Elements

A complete delivery address includes:

  1. Addressee name or other identifier and/or firm name where applicable.
  2. Private mail box designator and number (PMB 300 or #300).
  3. Urbanization name (Puerto Rico only, ZIP Code prefixes 006 to 009, if area is so designated).
  4. Street number and name (including predirectional, suffix, and postdirectional as shown in USPS ZIP+4 Product for the delivery address or rural route and box number (RR 5 BOX 10), highway contract route and box number (HC 4 BOX 45), or Post Office box number (PO BOX 458), as shown in USPS ZIP+4 Product for the delivery address). (“PO Box” is used incorrectly if preceding a private box number, e.g., a college mailroom.)
  5. Secondary address unit designator and number (such as an apartment or suite number (APT 202, STE 100)).
  6. City and state (or authorized two-letter state abbreviation). Use only city names and city and state name abbreviations as shown in USPS City State Product. Contact the National Customer Support Center (see 509.1.0) for more information about the City State Product.
  7. Correct 5-digit ZIP Code or ZIP+4 code. If a firm name is assigned a unique ZIP+4 code in the USPS ZIP+4 Product, the unique ZIP+4 code must be used in the delivery address.
1.5 Return Addresses
1.5.1 Purpose for Return Address

The return address tells the USPS where the sender of a mailpiece wants it returned if the piece cannot be delivered.

1.5.2 Return Address Elements

The return address contains elements corresponding to those for the delivery address. A return address is required in specific circumstances (see 1.5.3). If the sender’s name is not included in the return address, another clear designation (apartment, suite, or room number) is required to ensure proper handling of ancillary services and/or return of the piece. ZIP Codes (5-digit or ZIP+4) are required in the return address of all mail on which postage is paid with precanceled stamps or company permit imprint, and in the sender’s return address on Periodicals mail when “Address Service Requested” is specified. Official mail (penalty mail) also requires a ZIP Code in the return address.

1.5.3 Required Use of Return Addresses

The sender’s domestic return address must appear legibly on:

  1. Mail of any class bearing a printed ancillary service request or an ancillary service request embedded within an Intelligent Mail barcode.
  2. Official mail.
  3. Mail paid with precanceled stamps (except USPS Marketing Mail pieces weighing 13 ounces or less and bearing a mailer‘s postmark in accordance with 604.3.4).
  4. Matter bearing a company permit imprint.
  5. Priority Mail.
  6. Periodicals in envelopes or opaque wrappers.
  7. USPS Retail Ground.
  8. Package Services (except unendorsed Bound Printed Matter).
  9. Parcel Select.
  10. Registered Mail.
  11. Insured mail.
  12. Collect on delivery (COD) mail.
  13. Certified Mail if a return receipt is requested.
  14. Priority Mail Express.
  15. Detached addressed labels (DALs) and detached marketing labels (DMLs).
  16. Adult Signature.
  17. USPS Returns service and Parcel Return Service.
  18. All packaging containing hazardous, restricted, or perishable mail in accordance with Publication 52, Hazardous, Restricted, and Perishable Mail (221.11).
1.5.4 Use of Foreign Return Addresses

Regardless of destination, when U.S. postage is applied to a mailpiece, only a domestic return address is authorized, except when the addressee’s permanent residence is outside the United States or its territories (e.g., a tourist who lives abroad and is shipping an item home from the United States). This exception is applicable for only incidental non-commercial use for single-piece price mailpieces.

1.5.5 Postmark

An endorsement directing return to point of mailing (postmark) is not honored.

1.6 Ancillary Services

The USPS uses the return address to provide ancillary services requested by the mailer (e.g., “Return Service Requested”). The return address on any mailpiece endorsed for an ancillary service must identify where the piece is to be returned and where the mailer is prepared to pay applicable postage and fees for pieces returned or for ancillary service provided at the mailer’s request. A domestic return address must be placed in the upper left corner of the address side of the piece or the upper left corner of the addressing area.

1.7 Attachment of Different Class

If the names and addresses of the sender and intended recipient do not appear on both the host and attachment, the sender’s name and address must be placed on one piece and the recipient’s name and address on the other. Combination containers that have inseparable parts or compartments are mailable with the names and addresses on only one.

1.8 ZIP Codes
1.8.1 Purpose of ZIP Code

The ZIP (Zone Improvement Plan) Code system is a numbered coding system that facilitates efficient mail processing. The USPS assigns ZIP Codes. All Post Offices are assigned at least one unique 5-digit ZIP Code. Larger Post Offices may be assigned two or more 5-digit ZIP Codes (multi-5-digit ZIP Code offices). Separate 5-digit ZIP Codes are assigned to each delivery unit at these offices.

1.8.2 ZIP+4 - A Complete ZIP Code

The most complete ZIP Code is a nine-digit number consisting of five digits, a hyphen, and four digits, which the USPS describes by its trademark ZIP+4. The correct format for a numeric ZIP+4 code is five digits, a hyphen, and four digits. The first five digits represent the 5-digit ZIP Code; the sixth and seventh digits (the first two after the hyphen) identify an area known as a sector; the eighth and ninth digits identify a smaller area known as a segment. Together, the final four digits identify geographic units such as a side of a street between intersections, both sides of a street between intersections, a building, a floor or group of floors in a building, a firm within a building, a span of boxes on a rural route, or a group of Post Office boxes to which a single USPS employee makes delivery.

1.8.3 Numeric Delivery Point Barcode

A numeric equivalent of a delivery point barcode (DPBC) consists of five digits followed by a hyphen and seven digits as specified in 204.1.2.4. The numeric equivalent is formed by adding three digits directly after the ZIP+4 code.

1.9 Additional Addressing Standards by Class

Basic addressing standards are in the Prices and Eligibility section for each class of mail.

2.0 Restrictions

2.1 Dual Address

Mail with a dual address (both a street address and a Post Office box number) is delivered to the address immediately above the city and state (or to the Post Office box if both the street address and Post Office box are on the same line). If a ZIP+4 code or 5-digit ZIP Code is used, it must correspond to the address element immediately above the city and state (or with the Post Office box number in the address if both the street address and Post Office box are on the same line). These restrictions also apply to return addresses on mail (for more information, see Publication 28, Postal Addressing Standards).

2.2 More Than One Post Office

Mail with the name of more than one Post Office in the delivery address or return address is not acceptable for mailing.

2.3 Mail Addressed to CMRAs

Undeliverable mail with any alternative addressing format is disposed of as waste under 507.1.9.1, except for First-Class Mail, First-Class Package Service — Commercial parcels, and Priority Mail under 507.1.5.1b.

3.2 Simplified Address
3.2.1 Conditions for General Use

The following conditions must be met when using a simplified address on commercial mailpieces:

  1. The simplified address format (“Postal Customer” or one of the optional formats in 3.2.1a1 through 3.2.1a3) must be used on mail when complete distribution is made to each family (household residence) or boxholder on a rural or highway contract route, and to Post Office boxes in offices without city carrier service. The following also apply:
    1. Mailers may use a more specific address, such as “Rural Route Boxholder,” for mail intended to all boxholders on a rural route, followed by the name of the Post Office and state.
    2. Mailers may use “Residential Customer” to indicate that delivery is desired to residential addresses only.
    3. Use of the word “Local,” instead of the Post Office and state name, is optional; however the Postal Service recommends using the Post Office, state and ZIP Code for mail not dropshipped directly to a destination delivery unit.
    4. See 3.2.2 for governmental mail and 703.6.0 for Congressional mail.
  2. USPS Marketing Mail, Periodicals, and Bound Printed Matter flat-size mailpieces (including USPS Marketing Mail pieces allowed as flats under 3.2.1c), USPS Marketing Mail Product Samples mailed at saturation (Every Door) prices, and Periodicals irregular parcels for distribution to a city route or to Post Office boxes in offices with city carrier service may bear a simplified address, but only when complete distribution is made under the following conditions:

  3. USPS Marketing Mail flats with simplified addresses must have one dimension larger than a letter-size maximum dimension, except under 201.5.2.2. Simplified addressed pieces, when mailed under conditions in 201.5.2.2, are considered to be saturation flats. See 243.6.7 for pricing eligibility. Letter-size pieces that meet the size standards in 201.5.2.2 and that are addressed to rural routes may be mailed as letters or flats with simplified addresses at the mailer‘s option.
3.2.2 Use—Governmental Mailers

When distribution is to be made to each active possible delivery on city carrier routes or to each Post Office boxholder at a Post Office with city carrier service, the addressee’s name; mailing address; and city, state, and ZIP Code may be omitted from the address only on pieces mailed as official matter by agencies of the federal government (including mail with the congressional frank prepared under 703.6.0); any state, county, or municipal government; and the governments of the District of Columbia, the Commonwealth of Puerto Rico, and any U.S. territory or possession listed in 608.2.0.

The exceptional address format (“Jane Doe or Current Resident” or “Jane Doe or Current Occupant”) may be used on any mail except mail types listed in 3.1.2. The word “Current” is optional. The order of the words may be reversed (e.g., “Current Resident or Jane Doe” rather than “Jane Doe or Current Resident”).

3.4.2 Placement

The exceptional address format must be placed in the address block, with the following exceptions:

  1. If all the current resident/occupant information cannot be placed on the first or second line of the address, the exceptional address format may be placed no more than 3/4 inch above the address block.

4.1 General
4.1.1 Definition

Detached address labels (DALs) and detached marketing labels (DMLs) in their basic form (4.3.1 through 4.3.5) may be used by mailers as an optional method of printing addresses and postage indicia instead of printing addresses and postage on the items mailed. In addition to the basic form under 4.3.1 through 4.3.5, DMLs also include advertising under 4.3.6. For these standards, “item” refers to the types of eligible mail described in 4.2.1 through 4.2.3.

4.1.2 Alternative Address Format

DALs and DMLs may have alternative addressing formats under 3.0, subject to the applicable standards under 4.0

4.1.3 Ancillary Service Endorsements

Ancillary service endorsements are not permitted. A DAL or DML that is undeliverable as addressed is handled under 507.1.1 through 507.1.9 for the applicable class of mail. The accompanying item is treated as specified by the mailer under 4.5.

4.1.4 Documentation

Saturation flat mailings presented with DALs or DMLs that are not automation-compatible and correctly barcoded do not qualify for saturation prices. Instead, they may be entered at applicable basic carrier route prices. This standard (for automation-compatible barcoded DALs and DMLs) does not apply to DALs or DMLs with simplified addressing when correctly used with Periodicals flats.

4.2.2 USPS Marketing Mail Marketing Parcels — Product Samples

DALs or DMLs must be used with USPS Marketing Mail Marketing parcels mailed at targeted Product Sample prices and may be used with parcels mailed at saturation Product Sample prices.

The destination delivery unit (DDU) is determined using the Drop Shipment Product under the provisions for the DDU price in 266.3.0 through 266.6.0. The mail may not be prepared on pallets when the Drop Shipment Product indicates that the delivery unit that serves the 5-digit pallet destination cannot handle pallets. For such delivery units, mail with DALs or DMLs must be prepared in sacks. The trays or cartons of DALs or DMLs must be prepared under 4.4, placed on the same pallet as the pieces, and must be stretch-wrapped together as one unit.
  2. The mail is prepared in 5-digit sacks and entered at the destination delivery unit. The destination delivery unit is determined by using the Drop Shipment Product under the provisions for the DDU price in 266.3.0 through 266.6.0. DALs or DMLs must be bundled under 4.4 and presented to the destination delivery unit with the accompanying items to be distributed with the DALs or DMLs.

In addition, if DALs or DMLs accompany saturation mailings of Periodicals or USPS Marketing Mail flats, a correct Intelligent Mail barcode with an 11-digit routing code must be printed on each DAL or DML except when using a simplified address for Periodicals flats as allowed by standards.

4.3.3 One DAL/DML Per Item

Only one DAL or DML may be prepared for each accompanying item, and only one item may be identified for delivery per DAL or DML. (A single DAL or DML may not be prepared to deliver one each of different accompanying items or multiples of the same item.)

4.3.4 Required Information

The following words must appear in bold type at least 1/8 inch high on the front of each DAL and DML: “USPS regulations require that this address label be delivered with its accompanying postage-paid mail. If you should receive this label without its accompanying mail, please notify your local postmaster.%rdquo; The title or brand name of the item (which may include an illustration of the item) must also appear on the front or back of the DAL and DML to associate it with the accompanying item.

4.4 Mail Preparation
4.4.1 Notice to Delivery Office

Each delivery office to receive a DAL or DML mailing must be notified in writing at least 10 days before the requested delivery period begins. To ensure that the delivery office can readily relate the notice to the cartons containing the corresponding items, a copy of that letter must be enclosed with the DALs or DMLs unless the initial notice and the cartons used for the DALs or DMLs and items each conspicuously bears a mailing identification number. The letter must contain the following information:

Mailers must prepare DALs or DMLs as bundles in sacks or in cartons, unless prepared in trays under 4.4.6 when mailed with saturation flats or with Product Samples. Different size cartons may be used in the same mailing, but each must be filled with dunnage as necessary to ensure that the DALs or DMLs retain their orientation and presort integrity while in transit. Each carton of DALs or DMLs must bear a label showing the information in 4.4.5 unless a mailing identification number is used (see 4.4.1). Multiple containers of DALs or DMLs must be numbered sequentially (“1 of __,” “2 of __,” etc.).

4.4.3 Basic Standards for Items Distributed With DALs and DMLs

Except for bundles of saturation flats or Product Samples placed directly on pallets under 4.4.7, the items to be distributed with DALs or DMLs must be placed in cartons or prepared in bundles placed in sacks, subject to the standards for the price claimed. A label bearing the content description information in 4.4.5 must be affixed to each carton, sacked bundle, or pallet unless a mailing identification number is used (see 4.4.1). Cartons of items (including those on pallets) may be of different sizes but must be filled with dunnage as necessary to ensure the integrity of the items while in transit. The gross weight of each carton or sack must not be more than 40 pounds.

4.4.4 Combined Cartons

Both the DALs or DMLs and the accompanying items may be enclosed in the same carton when sent to a small volume 5-digit ZIP Code area. If the DALs or DMLs and the accompanying items are packed together, these standards apply:

  1. The DALs or DMLs must be bundled and labeled under 4.4.2 and placed on top of the items.
  2. The carton must be packed with dunnage to ensure the integrity of the contents while in transit.
  3. The gross weight of the carton must not exceed 40 pounds.
  4. The exterior of the carton must be labeled under 4.4.5 and marked “DALs ENCLOSED” or “DMLs ENCLOSED” in letters not less than 1/2 inch high.
4.4.5 Container Labels

Sacks, cartons, and pallets of DAL oe DML mail must be labeled under the preparation standards for the price claimed. A second label must be affixed to each bundle in a carton or sack to provide the following information (unless a mailing identification number is used under 4.4.1):

  1. Delivery Post Office name and 5-digit ZIP Code delivery area.
  2. Title, brand name, or other description of the items.
  3. Name and telephone number of the mailer or representative.
  4. Number of labels or items in the carton, as applicable.
  5. Instructions to open and distribute either the DALs or DMLs with matching items or the items with matching DALs or DMLs, as appropriate.
4.4.6 Optional Tray and Bundle Preparation

Mailers may prepare DALs or DMLs in letter trays according to 245.9.0 when DALs or DMLs are used in mailings of saturation flats or Product Samples. Bundles of saturation flats and bundles of Product Sample parcels to be distributed with DALs or DMLs may be prepared on 5-digit (and 5-digit scheme under L606 for parcels) pallets under 4.4.7. Do not use pallets when the Drop Shipment Product indicates the delivery unit that serves the 5-digit pallet destination cannot handle pallets. For such delivery units, mail with DALs or DMLs must be prepared in cartons or sacks. The tray(s) of corresponding DALs or DMLs must be placed on top of the accompanying pallet of flats, and the pallet contents must be secured with stretchwrap to avoid separation in transportation and processing. All containers must be labeled according to 4.4.5.

4.4.7 Optional Container Preparation

Bundles of flats, bundles of Product Samples, and cartons or sacks of items may be placed on pallets meeting the standards in 705.8.0. Cartons or trays of DALs or DMLs must be placed on pallets with the corresponding items under 4.4 and 705.8.0. The USPS plant manager at whose facility a DAL or DMLS mailing is deposited may authorize other containers for the portion of the mailing to be delivered in that plant‘s service area.

4.5 Disposition of Excess or Undeliverable Material

The letter required under 4.4.1 must either request that the delivery office contact the mailer (or representative) about excess DALs, DMLs, or items, or provide instructions for their treatment. (If the mailer does not provide information about excess DALs, DMLs, or items, such material is disposed of as waste by the USPS.) The mailer must choose one of the following options for each DAL or DML mailing and the items:

  1. Disposal of any excess material as waste.
  2. Return of the excess material to the mailer, postage due at the applicable single-piece price under 4.6.
  3. Holding of the excess material for pickup by the mailer (or representative). If pickup is not made within 15 calendar days of the notice to the mailer, the material is returned to the mailer postage due.
  4. Holding of the excess material while additional DALs, DMLs, or items are supplied (as applicable). If additional material is not supplied within 15 days of the notice to the mailer, the excess material is returned to the mailer postage due. Additional material must be sent prepaid to the delivery Post Office as First-Class Mail, First-Class Package Service — Retail, Priority Mail, or Priority Mail Express.
4.6 Postage
4.6.1 Prices

DAL or DML mailings are not eligible for automation prices, but the pieces may qualify for carrier route prices, subject to applicable standards. Mailers must pay a surcharge for each DAL or DML used with USPS Marketing Mail flats. See Notice 123—Price List for prices.

4.6.2 Postage Computation and Payment

Postage is computed based on the combined weight of the item and the accompanying DAL or DML. If the number of DALs/DMLs and items mailed is not identical, the number of pieces used to determine postage is the greater of the two. No postage refund is allowed in these situations. In addition, these methods of postage payment apply:

  1. Periodicals flats must be prepaid. A notice of entry must appear in the upper right corner of the DAL or DML.
  2. USPS Marketing Mail flats (except EDDM flats) and parcels and Bound Printed Matter pieces must be paid by permit imprint, which must appear on each DAL or DML.
  3. A surcharge applies to each DAL or DML used in a USPS Marketing Mail flats mailing and to each DAL or DML used with pieces mailed at USPS Marketing Mail Product Sample saturation parcel prices.
4.6.3 Returns

Postage for excess or undeliverable DALs or DMLs that are properly endorsed or for items being returned is computed at the single-piece price (First-Class Mail, First-Class Package Service — Retail, Priority Mail, or Package Services) applicable to the combined weight of the DAL or DML, and the accompanying item, regardless of whether both are returned. The total amount due for returned material, which includes the return postage and the applicable address correction fee for each DAL, DML, or item returned, is collected when the material is returned to the mailer.

4.6.4 Additional Items

Postage for additional material (DALs, DMLs, or items) mailed to the USPS under 4.5d must be prepaid as First-Class Mail, Priority Mail, or Priority Mail Express, subject to the eligibility standards for the price claimed and the conditions in 4.6.2.

5.0 Move Update Standards

5.1 Basic Standards

The Move Update standard requires the periodic matching of a mailer‘s address records with customer-filed change-of-address orders maintained by the USPS. Each address, except for mail bearing an alternative address format (under 3.0), in a mailing at commercial First-Class Mail presorted or automation prices, USPS Marketing Mail, or Parcel Select Lightweight prices is subject to the Move Update standard and must meet these requirements:

  1. Each address and associated addressee used on the mailpieces in a mailing must be updated within 95 days before the mailing date, with one of the USPS-approved methods in 5.2.
  2. The Move Update standard is met when an address used on a mailpiece in a mailing at any class of mail is updated under 5.2, and the same address is used in a First-Class Mail, USPS Marketing Mail, or Parcel Select Lightweight mailing within 95 days after the address has been updated.
5.2 USPS-Approved Methods

The following methods are authorized for meeting the Move Update standard:

  1. Address Change Service (ACS).
  2. National Change of Address Linkage System (NCOALink). This includes both pre-mail NCOALink processing systems and the physical mailpiece processing equipment system: National Change of Address Linkage System Mail Processing Equipment (NCOALink MPE). See the NCOALink page (NCOALink MPE Solutions) on PostalPro at https://postalpro.usps.com for more information on the MPE application.
  3. Applicable ancillary service endorsements under 507.1.5.1 or 507.1.5.3, except “Forwarding Service Requested.”
  4. For First-Class Mail only: Mailer Move Update Process Certification and USPS-approved alternative methods for mailers with legitimate restrictions on incorporating USPS-supplied change-of-address information into their mailing lists. The National Customer Support Center (see 608.8.1 for address) administers and approves both Mailer Move Update Process Certification and alternative methods.
  5. Election Mail, meaning any item mailed to or from authorized election officials and that enables citizens to participate in the voting process (e.g., ballots, voter registration cards, absentee voting applications and polling place notifications), may be mailed using a USPS-approved alternative method with the approval of the National Customer Support Center.
5.3 Move Update Verification

Mailers who submit any Full-Service volume in a calendar month will be verified pursuant to the Address Quality Census Measurement and Assessment Process beginning in the next calendar month. First-Class Mail and USPS Marketing Mail letter and flat-size mailpieces with addresses that have not been updated in accordance with the Move Update Standard will be subject to the Move Update assessment charge, if submitted via eDoc with unique Basic or Full-Service IMbs. Supporting details are described in Publication 685, Publication for Streamlined Mail Acceptance for Letters and Flats, available at postalpro.usps.com. The Move Update assessment charge will be assessed if:

  1. The percent of all qualifying mailpieces submitted in a calendar month that have a COA error is greater than the 0.5-percent error threshold, as determined by an analysis of the data captured by mail processing equipment. Qualifying mailpieces using a Green & Secure Change Service Requested STID will be included in the count of all qualifying mailpieces submitted in a calendar month, but will be excluded from assessment.
  2. Each mailpiece with an address containing COA errors in excess of the error threshold will be assessed the Move Update assessment charge.
5.4 Mailer Certification

The mailer’s signature on the postage statement or electronic confirmation during eDoc submission certifies that the Move Update standard has been met for the address records, including each address in the corresponding mailing presented to the Postal Service.

8.0 Presort Accuracy Validation and Evaluation (PAVE)

8.1 Presort Accuracy Validation and Evaluation (PAVE)
8.1.1 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.

8.1.2 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.

8.1.3 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.

9.0 Coding Accuracy Support System (CASS)

9.1 Basic Information
9.1.1 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.

9.1.2 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.

9.1.3 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; NCOALink; or DSF2 process.

9.2 Software Certification
9.2.1 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.

9.2.2 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.

9.2.3 Permissible Configurations

These are permissible configurations for address matching software:

  1. 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.
  2. 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.
  3. 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.
9.2.4 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.

9.3 Date of Address Matching and Coding
9.3.1 Update Standards

Unless Z4CHANGE 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.

9.3.2 Z4CHANGE List Matching

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

  1. The entire address list must first be matched and ZIP+4 coded with current CASS-certified software and the current USPS ZIP+4 Product.
  2. 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.
  3. 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.
  4. 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.
9.4 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 9.0.

9.5 Documentation
9.5.1 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.

9.5.2 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.

9.5.3 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.

9.5.4 Providing Required Data

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

  1. 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.
  2. 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.
9.5.5 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.

9.5.6 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.

9.5.7 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.

9.6 CASS Certification
9.6.1 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).

9.6.2 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.

9.6.3 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.

9.6.4 Certification Standards

To be CASS-certified:

  1. 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.
  2. 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.
  3. 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.
9.6.5 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.

10.0 Dual Shipping Labels

Dual shipping labels are used by private shipper to identify both the Postal Service and a private carrier as possible delivery agents. Items bearing dual shipping labels that are not tendered to the Postal Service for delivery must clearly indicate the private shipper responsible for delivering the item.
