1.0 General Information for Mail Preparation

1.1 Definition of Presort Process

Presort is the process by which a mailer prepares mail so that it is sorted to at least the finest extent required by the standards for the price claimed. Generally, presort is performed sequentially, from the lowest (finest) level to the highest level, to those destinations specified by standard and is completed at each level before the next level is prepared. Under standards for bundle reallocation for USPS Marketing Mail flats on pallets (see 705.8.0), mail will not necessarily be placed on the lowest (finest) level pallets (bundle reallocation is optional, but, if performed, must be done for the complete mailing job). Not all presort levels are applicable in all situations.

1.2 Definition of Mailings

Mailings are defined as:

  1. General. A mailing is a group of pieces within the same class of mail and the same processing category that may be sorted together and/or presented under a single minimum volume mailing requirement under the applicable standards. Generally, types of mail that follow different flows through the postal processing system (e.g., automation, nonautomation carrier route, and other nonautomation) and mail for each separate class and subclass must be prepared as a separate mailing. Other specific standards may define whether separate mailings may be combined, palletized, reported, or deposited together.
  2. USPS Marketing Mail. Except as provided in 243.3.6, the types of USPS Marketing Mail listed below may not be part of the same mailing.
    1. Automation Enhanced Carrier Route and any other type of mail.
    2. Automation price and any other type of mail.
    3. Enhanced Carrier Route and any other type of mail.
    4. Enhanced Carrier Route letter price pieces and Enhanced Carrier Route nonletter price pieces.
    5. Presorted price mail and any other type of mail.
    6. Machinable and nonmachinable pieces.
    7. Except as provided by standard, Regular mail may not be in the same mailing as Nonprofit mail, and Enhanced Carrier Route mail may not be in the same mailing as Nonprofit Enhanced Carrier Route mail.
    8. Customized MarketMail and any other type of mail.

1.4 Preparation Definitions and Instructions

For purposes of preparing mail:

  1. Pieces refers to individually addressed mailpieces.
  2. A full letter tray is one in which faced, upright pieces fill the length of the tray between 85% and 100% full.
  3. A less-than-full letter tray is one that contains mail for the same destination regardless of quantity or whether a full tray was previously prepared for that destination. Less-than-full trays may be prepared only if permitted by the standards for the price claimed.
  4. An overflow letter tray is a less-than-full tray that contains all pieces remaining after preparation of full trays for the same destination. Overflow trays may be prepared only if permitted by the standards for the price claimed.
  5. A full flat tray is one that is physically full. Although a specific minimum volume is required (at least a single stack of mail lying flat on the bottom of the tray and filling the tray to the bottom of the handholds) before a tray may or must be prepared to the corresponding presort destination, trays must be filled with additional available pieces (up to the reasonable capacity of the tray) when standards require preparing full trays.
  6. A full sack is defined in the standards for the class and price claimed.
  7. A 5-digit scheme sort for automation letters yields 5-digit scheme trays for 5-digit ZIP Codes identified in labeling list L012 and 5-digit trays for other areas. The 5-digit ZIP Codes in each scheme are treated as one presort destination subject to a minimum volume, with no further separation by 5-digit ZIP Code required. Trays prepared for a 5-digit scheme destination that contain pieces for only one of the schemed 5-digit ZIP Codes are considered 5-digit scheme sorted. When standards require 5-digit/scheme sort, mailers must prepare all possible 5-digit scheme trays, then prepare all possible 5-digit trays.
  8. A 5-digit scheme sort for flats meeting the automation-compatibility standards in 201.3.0 yields 5-digit scheme bundles for those 5-digit ZIP Codes identified in L007 and 5-digit bundles for other ZIP Codes. When standards require 5-digit/scheme sort, mailers must prepare all possible 5-digit scheme bundles and flat trays of flats, and then prepare all possible 5-digit bundles and flat trays. The 5-digit ZIP Codes in each scheme are treated as a single presort destination subject to a single minimum volume, with no further separation required. Bundles prepared for a 5-digit scheme destination and that contain pieces for only one of the schemed 5-digit ZIP Codes are still considered 5-digit scheme sorted and are labeled accordingly. Bundles must be labeled using an optional endorsement line (OEL) under 203.7.0 or with a red “5 SCH” bundle label. Bundles are placed in appropriate containers based on the OEL “label to” 5-digit ZIP Code, or L007 , Column B.
  9.

Flat trays/sacks or pallets prepared for a 5-digit scheme carrier routes destination and that contain carrier route bundles for only one of the schemed 5-digit areas are still considered to be sorted to 5-digit scheme carrier routes and are labeled accordingly. The 5-digit scheme carrier routes sort is required for carrier route bundles of Enhanced Carrier Route USPS Marketing Mail flats. Preparation of 5-digit scheme carrier routes flat trays/sacks or pallets must be done for all 5-digit scheme destinations.
  10. A 5-digit scheme sort for USPS Marketing Mail flats prepared as bundles on pallets yields 5-digit scheme pallets containing automation price and nonautomation price 5-digit bundles for those 5-digit ZIP Codes listed in L001 and yields 5-digit pallets containing automation price and nonautomation price 5-digit bundles for other areas. The 5-digit ZIP Codes in each scheme are treated as a single presort destination subject to a single minimum pallet volume, with no further separation by 5-digit ZIP Code required. Pallets prepared for a 5-digit scheme destination that contain 5-digit bundles for only one of the schemed 5-digit areas are still considered to be sorted to the 5-digit scheme and are labeled accordingly. The 5-digit scheme sort is required for USPS Marketing Mail flats. The 5-digit scheme sort may not be used for other mail prepared on pallets, except for 5-digit bundles of USPS Marketing Mail irregular parcels that are part of a mailing job that is prepared in part as palletized flats at automation prices. Preparation of 5-digit scheme pallets must be done for all 5-digit scheme destinations.
  11. A merged 5-digit sort for USPS Marketing Mail flats prepared in flat trays yields merged 5-digit flat trays that contain carrier route bundles and/or automation price 5-digit bundles, and/or Presorted price 5-digit bundles that are all for a 5-digit ZIP Code that has an “A” or “C” indicator in the Carrier Route Indicators field in the City State Product that allows combining carrier route bundles, automation price 5-digit bundles, and Presorted price 5-digit bundles in the same 5-digit flat tray or pallet. The merged 5-digit sort is optional for USPS Marketing Mail flats prepared in flat trays. Flat trays prepared for a merged 5-digit destination and that contain only a single price level of bundle(s) (only carrier route bundle(s) or only automation price 5-digit bundle(s) or only Presorted price 5-digit bundle(s)) or that contain only two price levels of bundle(s) are still considered to be merged 5-digit sorted and are labeled accordingly. If merged 5-digit flat trays are prepared, this must be done for all 5-digit ZIP Code destinations with an “A” or “C” indicator in the Carrier Route Indicators field in the City State Product that allows combining carrier route bundles, automation price 5-digit bundles, and Presorted price 5-digit bundles in the same 5-digit container.
  12. A merged 5-digit sort for USPS Marketing Mail flats prepared as bundles on pallets yields merged 5-digit pallets that contain carrier route bundles and noncarrier route 5-digit bundles (automation price 5-digit bundles and/or Presorted price 5-digit bundles). The merged 5-digit sort is optional for USPS Marketing Mail flats prepared in flat trays under 705.10.0. Flat trays or pallets prepared for a merged 5-digit destination and that contain only a single price level of bundle(s) (only carrier route bundle(s) or only automation price 5-digit bundle(s) or only Presorted price 5-digit bundle(s)) or only two price levels of bundle(s) are still considered to be merged 5-digit sorted and must be labeled accordingly.

  14. A merged 5-digit scheme sort for USPS Marketing Mail flats prepared as bundles on pallets under 705.8.0, 705.10.0, 705.12.0, or 705.13.0 yields merged 5-digit scheme pallets that contain carrier route bundles and noncarrier route 5-digit bundles (automation price and/or Presorted price 5-digit bundles) for those 5-digit ZIP Codes that are part of a single scheme as shown in L001. Pallets prepared for a merged 5-digit scheme destination that contain only a single price level of bundle(s) (only carrier route bundle(s) or only automation price 5-digit bundle(s) or only Presorted price 5-digit bundle(s)), or only two price levels of bundle(s), or bundles for only one of the schemed 5-digit ZIP Codes are still considered to be merged 5-digit scheme sorted and must be labeled accordingly. If preparation of merged 5-digit scheme pallets is performed, it must be done for all 5-digit scheme destinations in L001.
  15. A 5-digit/scheme sort for USPS Marketing Mail parcels yields 5-digit scheme sacks or pallets for those 5-digit ZIP Codes listed in L606 and 5-digit sacks or pallets for other ZIP Codes. The 5-digit ZIP Codes in each scheme are treated as a single presort destination subject to a single minimum volume (if required), with no further separation by 5-digit ZIP Code required. Sacks or pallets prepared for a 5-digit scheme destination that contain pieces for only one of the schemed 5-digit ZIP Codes are still considered 5-digit scheme sorted and are labeled accordingly.
  16. A 3-digit scheme sort for letters yields 3-digit scheme trays for those 3-digit ZIP Code prefixes listed in L003 and 3-digit trays for other areas. The 3-digit ZIP Code prefixes in each scheme are treated as a single presort destination subject to a single minimum tray volume, with no further separation by 3-digit prefix required. Trays prepared for a 3-digit scheme destination that contain pieces for only one of the schemed 3-digit areas are still considered 3-digit scheme sorted and are labeled accordingly. When standards require 3-digit/scheme sort, mailers must prepare all possible 3-digit scheme trays, then prepare all possible 3-digit trays.
  17. A 3-digit scheme sort for flats meeting the automation-compatibility standards in 201.6.0 yields 3-digit scheme bundles for those 3-digit ZIP Codes identified in L008. When standards require 3-digit/scheme sort, mailers must prepare all possible 3-digit scheme bundles of flats, then prepare all possible 3-digit bundles. The 3-digit ZIP Codes in each scheme are treated as a single presort destination subject to a single minimum volume, with no further separation by 3-digit ZIP Code required. Bundles prepared for a 3-digit scheme destination that contain pieces for only one of the schemed 3-digit ZIP Codes are still considered 3-digit scheme sorted and are labeled accordingly. Bundles must be labeled using an optional endorsement line (OEL) under 203.7.0 or with a green “3 SCH” bundle label. Bundles are placed in appropriate containers using the OEL “label to” 3-digit ZIP Code or using L008 column B.
  18. [7-14-24] An origin 3-digit (or origin 3-digit scheme) tray for letters and flats contains all mail (regardless of quantity) for a 3-digit ZIP Code (or 3-digit scheme) area processed by the SCF/LPC in whose service area the mail is verified. A separate tray may be prepared for each 3-digit ZIP Code (or 3-digit scheme) area. A tray may be prepared for each 3-digit (or 3-digit scheme) area served by the SCF/LPC/plant where mail is entered (if that is different from the SCF/LPC/plant serving the Post Office where the mail is verified). In all cases, only one less-than-full tray may be prepared for each 3-digit (or 3-digit scheme) area.
  19. [7-14-24] An origin AADC tray contains all mail (regardless of quantity) for an AADC ZIP Code area processed by the AADC or SCF/LPC in whose service area the mail is verified/entered. Only one less-than-full tray may be prepared for each AADC area.
  20. The required at [quantity] instruction (e.g., “required at 10 pieces”) means that the particular unit must be prepared for the corresponding presort level whenever the specified quantity of mail is reached or exceeded. Bundles and containers may contain more than the specified required at quantity up to the applicable maximum physical size. Subject to applicable price eligibility standards, smaller quantities may be prepared only if permitted. Where specified by standard, required preparation applies only if the mailer chooses to qualify for the corresponding price.
  21. The optional at [quantity] instruction means that the particular unit may be prepared for the corresponding presort level whenever the specified quantity of mail is reached or exceeded. Bundles or containers may contain more than the specified optional at quantity up to the applicable maximum physical size. Smaller quantities may be prepared only if permitted by applicable price eligibility standards. Standards for quantities with which preparation is optional are often followed by standards for larger quantities with which preparation is required.
  22. [7-14-24] Entry [facility] (or origin [facility]) refers to the USPS mail processing facility (e.g., “entry NDC/RPDC”) that serves the Post Office at which the mail is entered by the mailer. If the Post Office where the mail is entered is not the one serving the mailer’s location (e.g., for plant-verified drop shipment), the Post Office of entry determines the entry facility. The following also apply:
    1. Entry SCF/LPC (letter and flats) and Entry SCF/RPDC (parcels) includes both single-3-digit and multi-3-digit SCFs.
    2. Entry NDC/RPDC includes subordinate ASFs unless otherwise specified.
  23. The group pieces instruction means the pieces are to be sorted together but not secured into a bundle.
  24. A bundle is a group of addressed pieces secured together as a unit. Bundle preparation is described in 2.0.
  25. [7-14-24] A “logical” presort destination represents the total number of pieces that are eligible for a specific presort level based on the required sortation, but which might not be contained in a single bundle or in a single container (flat tray, sack or pallet) due to applicable preparation requirements or the size of the individual pieces. For example, there may be 42 mailpieces for ZIP Code 43112 forming a USPS Marketing Mail “logical” 5-digit bundle, and they are prepared in three physical 5-digit bundles because of the applicable weight and height restrictions on bundles. For pallets, 2,800 pounds of mail may be destined to an SCF/LPC (letters and flats) or SCF/RPDC (parcels) destination, and these would form the “logical” SCF pallet, but the mail is placed on two SCF pallets, each weighing 1,400 pounds because of the 2,200-pound-maximum pallet-weight requirement.
  26. Cobundling is an alternate preparation method available under 705.11.0 for USPS Marketing Mail that allows the combining of flat-size automation price and Presorted price pieces within the same bundle under the single minimum bundle size requirement. Regardless of the class of mail, pieces may not be combined in more than one physical bundle for each logical presort destination unless presented using an approved manifest mailing system under 705.2.0.
1.5 Optional Containerization for Flats

Mailers may prepare pallets or other USPS-approved containers as described in 705.8.10.2 or according to local customer/supplier agreements.

    2. Line 2: “STD LTR MACH WKG.”
5.4 Nonmachinable Preparation
5.4.1 Nonmachinable Bundling

Except as provided in 203.4.4, bundling is required before traying. A bundle must be prepared when the quantity of addressed pieces for a required presort level reaches a minimum of 10 pieces. Smaller volumes are not permitted except for mixed ADC bundles. Preparation sequence, bundle size, and labeling:

  1. 5-digit (required); 10-piece minimum; red Label 5 or optional endorsement line (OEL); labeling not required for pieces in full 5-digit trays.
  2. 3-digit (required); 10-piece minimum; green Label 3 or OEL.
  3. ADC (required); 10-piece minimum; pink Label A or OEL.
  4. Mixed ADC (required); no minimum; tan Label X or OEL.
5.4.2 Traying and Labeling

When all full trays for a destination have been prepared, mailers may include a group of 10 or more overflow pieces for that destination in a qualified tray at either of the next two tray levels. For example, overflow pieces for a 5-digit destination may be placed into an existing correct 3-digit tray; if a 3-digit tray that includes the 5-digit destination does not exist, the overflow pieces may be placed into the correct existing ADC tray. Bundle the overflow pieces separately with the correct presort bundle label or OEL; the pieces will still qualify for the 5-digit price. Mailers must note these trays on standardized documentation (see 203.3.2). Preparation sequence, tray size, and labeling:

  1. 5-digit (required); 150-piece minimum; labeling

    2. Line 2: “STD LTR MANUAL WKG.”
5.5 Residual Pieces

Mailers entering USPS Marketing Mail residual pieces that do not qualify for USPS Marketing Mail prices, and paying the First-Class Mail prices (but prepared “as is” under 244.5.0), must prepare these pieces in separate trays from the automation and presort pieces. Mailers must label the trays under 204.3.0 using CIN code 560 on residual trays. Label trays as follows:

  1. Line 1: Use L011, Column B.
  2. Line 2: Use the human-readable content line corresponding to content identifier number 560 (see Exhibit 204.3.2.4).
  3. Line 3: Office of mailing or mailer information.

6.0 Preparing Enhanced Carrier Route Letters

6.1 Basic Standards

  1. All pieces must meet the standards for basic eligibility in 243.2.0 through 243.4.0 and specific eligibility in 243.6.0. Nonprofit Enhanced Carrier Route USPS Marketing Mail must meet the additional eligibility standards in 703.1.0.
  2. All pieces in each mailing must be in the letter-size processing category. Unless excepted by standard, letter-size pieces must be prepared in letter trays.
  3. All pieces must meet the applicable general preparation standards in 2.0 through 4.0 and 202, and the following:
    1. Pieces must be sequenced according to 6.8.
    2. Pieces with a simplified address format must meet the standards in 602.3.0.
  4. All pieces in the mailing must meet the specific sortation and preparation standards in 6.0 or the palletization standards in 705.8.0.
  5. Sortation determines price eligibility as specified in 243.6.0.
6.2 Marking

All regular and Nonprofit USPS Marketing Mail Enhanced Carrier Route pieces must be marked under 202.3.0. All pieces must also be marked “ECRLOT” for basic price, “ECRWSH” for high density or high density plus price, or “ECRWSS” for saturation price. Pieces in carrier route mailings under 6.7 must bear carrier route information lines under 203.8.0.

6.3 Residual Pieces

Pieces not sorted as a carrier route mailing must be prepared as a separate mailing at USPS Marketing Mail automation or Presorted prices or at the applicable single-piece First-Class Mail or USPS Ground Advantage — Retail prices.

6.4 Carrier Route Bundle Preparation

Prepare carrier route bundles of letter-size mail as follows:

  1. Mailers must prepare only carrier route bundles, except under 6.7. Carrier route bundles are not permitted in full carrier route trays, except for card-size pieces.
  2. Except under 203.4.12 or 6.5, carrier route bundles must contain at least 10 pieces.
  3. The method of labeling a carrier route bundle is based on the following tray levels:
    1. Carrier route tray: No bundle labeling is required.
    2. 5-digit or 3-digit carrier routes tray: Bundles must have a facing slip unless the pieces in the bundle have a carrier information line or an optional endorsement line (OEL).
6.5 Bundles and Trays With Fewer Than the Minimum Number of Pieces Required

As a general exception to 6.4, a mailer may prepare a bundle with fewer than 10 pieces and a less-than-full carrier route tray when they are claiming the saturation price for the contents and the applicable density standard is met.

6.6 General Traying and Labeling

For all ECR letters over 3.5 ounces and all ECR letters that are not automation-compatible or delivery-point barcoded, prepare trays as explained below. Also prepare trays as explained below when a mailing contains some pieces over 3.5 ounces and some pieces up to 3.5 ounces. Pieces with simplified addresses must be prepared in separate trays from pieces with other forms of addressing. For ECR automation-compatible letters that are delivery-point barcoded and weigh up to 3.5 ounces, prepare trays under 6.7. Preparation sequence, tray size, and labeling:

  1. Carrier route: required; full trays only, no overflow.
    1. Line 1: city, state, and 5-digit ZIP Code on mail (see 203.5.11 for overseas military mail).
    2. Line 2: for saturation, “STD LTR MACH WSS,” followed by route type and number; for high-density or high density plus, “STD LTR MACH WSH,” followed by route type and number; for basic, “STD LTR MACH LOT,” followed by route type and number.

    2. Line 2: “STD LTR 3D CR-RT MACH.”
  4. For trays containing barcoded automation-compatible letter-size pieces over 3 ounces or nonmachinable letter-size pieces, use these Line 2 label designations in place of “MACH”:
    1. Trays containing barcoded, automation-compatible pieces over 3 ounces: “BC.”
    2. Trays containing nonmachinable pieces: “MAN.”
    3. Trays containing simplified address pieces: “MAN.”
6.7 Traying and Labeling for Automation-Compatible ECR Letters

[7-14-24] Mailers must make full carrier route and 5-digit carrier routes trays, when possible, for automation-compatible, delivery-point barcoded ECR letters that weigh up to 3.5 ounces. Except for card-size pieces, pieces must not be bundled. Group pieces together by carrier route in 5-digit and 3-digit carrier routes trays. If pieces for one carrier route do not result in a full tray, mailers must combine pieces from at least two routes to make full 5-digit carrier routes trays, grouping pieces together by carrier route. If pieces for multiple carrier routes do not result in a full 5-digit tray, mailers must combine pieces from at least two 5-digit ZIP Codes to make 3-digit carrier routes trays, grouping pieces together by carrier route. If pieces fill more than one tray but do not fill an additional tray, mailers must place excess pieces in a tray at the next sortation level. (See 6.10 for optional 5-digit-tray preparation). Preparation sequence, tray size, and labeling:

  1. Carrier route: required; full trays only, no overflow.
    1. Line 1: city, state, and 5-digit ZIP Code on mail (see 203.5.11 for overseas military mail).
    2. Line 2: for saturation, “STD LTR BC WSS,” followed by route type and number; for high-density, “STD LTR BC WSH,” followed by route type and number; for basic, “STD LTR BC LOT,” followed by route type and number.
  2. 5-digit carrier routes: required; no overflow, no bundling.
    1. Line 1: city, state, and 5-digit ZIP Code on mail (see 203.5.11 for overseas military mail).
    2. Line 2: “STD LTR 5D CR-RT BC.”
  3. 3-digit carrier routes: required; bundling required in less-than-full trays.
    1. Line 1: city, state, and 3-digit ZIP Code prefix shown in L002, Column A, that corresponds to 3-digit ZIP Code prefix on mail.
    2. Line 2: “STD LTR 3D CR-RT BC.”
6.8 Delivery Sequence Standards
6.8.1 Basic Standards

Mailpieces for which a walk-sequence discount is claimed must be organized in the delivery sequence determined by the USPS and prepared as a carrier route mailing under 6.1 through 6.7 and the standards below. Pieces prepared with a simplified address must also meet the corresponding standards.

6.8.2 Missing Addresses

Some mailpieces cannot be sequenced because an exact match for a name or address cannot be obtained. These pieces may be included in a sequenced mailing only if they are placed behind or after the sequenced mail. Arrange these pieces:

  1. Alphabetically by complete street name, then either in ascending order by ZIP+4 code sector segments or numerically in ascending order by primary address.
  2. Numerically for numbered streets, then either in ascending order by ZIP+4 code sector segments or numerically in ascending order by primary address.
6.8.3 Updating Walk Sequence Information—General

Walk-sequence price pieces prepared with other than a simplified address format under 6.8.4 must be sequenced using USPS data from one of the following sources, issued within 90 days before the mailing date:

  1. The Computerized Delivery Sequence (CDS) file.
  2. The Delivery Sequence File (DSF) or Delivery Sequence File, Second Generation (DSF2).
  3. Delivery sequence information from USPS address sequencing services, as requested by the customer.
6.8.4 Updating Delivery Statistics Information for Simplified Addressing

Mailpieces prepared with a simplified address must be based on delivery stop information obtained within 90 days before the mailing date from the Delivery Statistics File, in accordance with 509.1.11.

6.8.5 Out-of-Date Walk Sequence Information

Mailings prepared with out-of-date walk-sequencing or delivery statistics information are not eligible for prices requiring walk-sequence preparation.

6.8.6 Updating Line-of-Travel Sequence Information

Unless the mail is prepared in carrier walk sequence, line-of-travel (LOT) sequence is required for mailings at USPS Marketing Mail Enhanced Carrier Route basic prices. LOT sequence is not an exact walk sequence but a sequence of ZIP+4 codes arranged in the order that the route is served by a carrier. (First the ZIP+4 groups are sequenced, then the addresses within each are identified as being in ascending or descending order.) The USPS eLOT product provides a list of the ZIP+4 codes each carrier route serves, identifies the order in which they are delivered, and provides an indicator specifying whether the addresses that share the same ZIP+4 code must be sorted in ascending or descending order. When a range of ZIP+4 codes on the same carrier route are assigned the same sequence number, the addresses bearing those ZIP+4 codes must be arranged in ascending ZIP+4 code order before the sequence number is assigned. LOT information must be updated within 90 days before the date of mailing.

6.9 Delivery Sequence Documentation
6.9.1 Basic Standards

[1-21-24] The postage statement must be annotated in the “Carrier Route Sequencing Date” block on page 1. The mailer must annotate the postage statement to show the earliest (oldest) date of the method used to obtain sequencing information for the mailing. The mailer’s electronic confirmation during eDoc submission certifies that this standard has been met when the corresponding mail is presented to USPS. The mailer must maintain documentation to substantiate compliance with the standards for carrier route sequencing. Unless submitted with each corresponding mailing, the mailer must be able to provide the USPS with documentation (if requested) of accurate sequencing or delivery statistics for each carrier route to which pieces are mailed. Acceptable forms of documentation are:

  1. The invoice showing that the addresses came from CDS.
  2. DSF2 invoice or documentation.
  3. Copies of the delivery unit summaries that served as the mailer’s bills for address sequencing service charges.
  4. Evidence of receipt of information from postmasters for simplified address mailings (see 509.1.0).
  5. Form 3553 showing the date of the eLOT product used, or the date from the USPS Qualification report produced by presort software.
6.9.2 High Density and High Density Plus

For each carrier route to which high density or high density plus mail is addressed, the mailer must document the total number of addressed pieces to the route.

6.9.3 Saturation Density—Simplified Address Mail

For each carrier route to which mail with a simplified address is sent at the saturation price, the mailer must be able to document that the mailing meets the applicable density standard. This documentation must show the total number of active possible deliveries and the total number to which mailpieces in the mailing are being addressed, by 5-digit ZIP Code and, within each, by carrier route. It must be submitted with each applicable mailing.

6.9.4 Saturation Density—Other Mail

For each carrier route to which mail without a simplified address is sent at the saturation price, the mailer must be able to document that the mailing meets the applicable density standards. This documentation must show either the total number of active possible residential deliveries and the number and percentage to which mailpieces are addressed, or the total number of all active possible deliveries and the number and percentage to which mailpieces are addressed, depending on whether qualification is based on the 90% or 75% criterion, respectively. The documentation must be listed by 5-digit ZIP Code and, within each, by carrier route. It must be submitted with each applicable mailing.

6.9.5 Both Prices

If a mailing contains pieces qualifying for more than one walk-sequence price, the documentation required by 6.9.2, 6.9.3, or 6.9.4 may be combined. Entries for pieces at the high density or high density plus prices must be so annotated on the documentation. For the entire mailing, a summary of the total number of pieces at each price must be provided. This documentation must be submitted with each mailing.

6.9.6 Carrier Route Price

If a mailing includes walk-sequence price and basic carrier route price pieces, in addition to the information required by 6.9.2 through 6.9.5, the documentation for the basic carrier route price mail must show, by 5-digit ZIP Code and, within each, by carrier route, the total number of addressed pieces at each price for each carrier route to which pieces are addressed. Pieces qualifying for the basic carrier route price must be so annotated. For the entire mailing, a summary by 5-digit ZIP Code of the total number of pieces at each price must be provided. This documentation must be submitted with each mailing.

[7-14-24]
6.10 Optional 5-Digit-Tray Preparation for High Density and High Density Plus ECR Automation-Compatible Letters
6.10.1 Basic Standards

An optional 5-digit-tray preparation allows combining multiple mail owners’ High Density, High Density Plus, and 5-digit automation-compatible letters in a letter tray when meeting the following standards:

  1. Each individual mail owner must meet the minimum quantities in 243.6.4.2 for High Density (HD) and High Density Plus (HD+) to claim HD/HD+ prices with a minimum combined 150 pieces of 5-digit, HD or HD+ in a 5-digit tray.
  2. The separate requirement of 150 pieces for 5-digit is waived.
  3. The minimums must be achieved by a single mail owner defined by the mail owner’s individual Mailer ID (MID) and/or Customer Registration ID (CRID) in the “By/For” of the eDoc for each carrier route.
  4. Walk sequencing is not required within the letter trays.
  5. Bundling and facing slips are not required.
  6. The optional tray preparation must meet the HD and HD+ marking requirements in 6.2.
  7. The optional tray preparation must be used for the entire mailing within eDoc.
6.10.2 [7-14-24] Traying and Labeling

Mailers must make full 5-digit trays for automation-compatible, delivery-point barcoded letters that weigh up to 3.5 ounces and meet the standards of 6.10.1. Bundling or facing slips are not required. Preparation sequence, tray size, and labeling:

  1. Same carrier route to same 5-digit; full trays only:
    1. Line 1: City, state, and 5-digit ZIP Code on mail.
    2. Line 2: “STD LTR BC.”
  2. Multiple carrier routes to same 5-digit; full trays only:
    1. Line 1: City, state, and 5-digit ZIP Code on mail.
    2. Line 2: “STD LTR 5D MXD CR-RTS BC.”

7.0 Preparing Automation Letters

7.1 Basic Standards

Letter-size automation price USPS Marketing Mail must be prepared under 7.0 and the eligibility standards for the price claimed. Trays must bear barcoded tray labels under 203.5.0.

7.2 Mailings

All pieces in a mailing must meet the standards in 201.1.0, and 201.3.0, and must be sorted together to the finest extent required for the price claimed. The definitions of a mailing and permissible combinations are in 1.0.

7.3 Marking

All USPS Marketing Mail automation price pieces must be marked under 202.3.0. Pieces claimed at an automation price must bear the appropriate class marking and “AUTO,” except as provided in 202.3.0. Pieces not claimed at an automation price must not bear “AUTO” unless First-Class Mail single-piece price postage is affixed or a corrective single-piece price marking (“Single-Piece” or “SNGLP”) is applied.

7.4 General Preparation

Grouping, bundling, and labeling are not generally required or permitted, except bundling is required in any mailing consisting entirely of card-size pieces and for pieces in overflow and less-than-full trays, and grouping is required under 7.5.

7.5 Tray Preparation

Instead of preparing overflow trays with fewer than 150 pieces, mailers may include these pieces in an existing qualified tray of at least 150 or more pieces at the next tray level. (For example, if a mailer has 30 overflow 5-digit pieces for ZIP Code 20260, these pieces may be added to an existing qualified AADC tray for the correct destination and the overflow 5-digit pieces will still qualify for the 5-digit price). Mailers must note these trays on standardized documentation (see 203.3.2). Pieces that are placed in the next tray level must be grouped by destination and placed in the front or back of that tray. Mailers may use this option selectively for AADC ZIP Codes. This option does not apply to origin/entry AADC trays. Preparation sequence, tray size, and Line 1 labeling:

  1. 5-digit/scheme: optional, but required for 5-digit price (150-piece minimum); overflow allowed. Make 5-digit scheme trays first, then 5-digit trays; see 1.4f. For Line 1, label as follows:
    1. For 5-digit scheme trays, use destination shown in labeling list L012.
    2. For 5-digit trays, use city, state, and 5-digit ZIP Code destination on pieces (see 203.5.11 for overseas military mail).
  2. AADC: optional, but required for AADC price (150-piece minimum except no minimum for origin entry AADC); overflow allowed; group pieces by 3-digit (or 3-digit scheme) ZIP Code prefix. For Line 1, use L801, Column B.
  3. [7-14-24] Mixed AADC: required (no minimum); group pieces by AADC when overflow pieces from AADC trays are placed in mixed AADC trays. For Line 1 labeling: use L011, Column B. Use L010, Column B if entered at an ASF/NDC/RPDC or for mail placed on an ASF/NDC/RPDC, or SCF/LPC pallet under the option in 705.8.10.3.
7.6 Tray Line 2

Line 2: “STD LTR” and:

  1. 5-digit scheme: “BC 5D SCHEME.”
  2. 5-digit: “5D BC.”
  3. AADC: “AADC BC.”
  4. Mixed AADC: “BC WKG.”
7.7 Presentation

Upon presentation of letter-size automation price USPS Marketing Mail mailings to USPS for verification, mailers must present all mixed AADC trays together, and such trays must either be adjacent to one another or side by side, and must be placed as the top layer(s) on any given container.

8.0 Preparing Nonautomation Flats

8.1 Basic Standards

All mailings and all pieces in each mailing at Regular USPS Marketing Mail and Nonprofit USPS Marketing Mail nonautomation prices are subject to specific preparation standards in 8.2 through 8.9 and to these general standards (automation price mailings must be prepared under 10.0):

  1. All pieces must be in the flat-size processing category.
  2. All pieces must meet the applicable general preparation standards in 1.0 through 4.0 and the following:
    1. All regular and Nonprofit USPS Marketing Mail pieces must be marked under 202.3.0. Regular and Nonprofit USPS Marketing Mail pieces must not be marked “ECRLOT,” “ECRWSH,” “ECRWSS,” “AUTO,” or “Single-Piece” (or “SNGLP”).
    2. 7Unless excepted by standard, all pieces must be in the flat-size processing category and must be prepared in flat trays or on pallets. Certain flat-size pieces may be prepared in letter trays under 3.0.
  3. All pieces in the mailing must meet the specific sortation and preparation standards in 8.0 or the palletization standards in 705.8.0. Flat-size pieces may be prepared under 705.9.0 through 705.13.0.
  4. Sortation determines price eligibility as specified in 243.5.0.
8.2 Bundle Preparation

[1-21-24] Bundling in flat trays is optional, and any bundles must be trayed and labeled separately from loose flats prepared in flat trays. Prepare a bundle when the quantity of addressed pieces for a required presort level reaches the required minimum bundle size specified in 8.3. Smaller volumes are not permitted except under 203.4.0 and for mixed ADC bundles.

8.3 Bundling and Labeling

Mailings consisting entirely of pieces meeting the automation-compatibility criteria in 201.6.0 must be prepared in 5-digit scheme bundles for those 5-digit ZIP Codes identified in L007 and in 3-digit scheme bundles for those 3-digit ZIP Codes identified in L008. Preparation sequence, bundle size except as allowed under 203.4.12, and labeling:

  1. 5-digit scheme (required for flats meeting the automation-compatibility standards in 201.6.0), see definition in 1.4j:
    1. For mailings containing only pieces weighing 5 ounces (0.3125 pound) or less: 15-piece minimum; red Label 5 SCH, or OEL.
    2. For mailings containing any pieces weighing more than 5 ounces (0.3125 pound): 10-piece minimum; red Label 5 SCH, or OEL.
  2. 5-digit (required), see definition in 1.4j:
    1. For mailings containing only pieces weighing 5 ounces (0.3125 pound) or less: 15-piece minimum; red Label 5 or OEL.
    2. For mailings containing any pieces weighing more than 5 ounces (0.3125 pound): 10-piece minimum; red Label 5 or OEL.
  3. 3-digit scheme (required for flats meeting the automation-compatibility standards in 201.6.0), see definition in 1.4o; 10-piece minimum; green Label 3 SCH, or OEL.
  4. 3-digit (required), see definition in 1.4o; 10-piece minimum; green Label 3 or OEL.
  5. ADC (required); 10-piece minimum; pink Label A or OEL.
  6. Mixed ADC (required); no minimum; tan Label X or OEL.
8.4 Required Traying

Except as provided in 8.6, flat tray,or a letter tray under 3.0, must be prepared when the quantity of mail for a required presort destination reaches a full flat tray (up to the handholds), 125 pieces, or 15 pounds, whichever occurs first, subject to these conditions:

  1. For identical-weight pieces, mailers must apply these methods:
    1. Pieces weighing 1.92 ounces (0.12 pound) or less must be prepared using the 125-piece minimum.
    2. Pieces weighing more than 1.92 ounces must be prepared using the 15-pound minimum.
  2. For nonidentical-weight pieces, mailers must apply either one of these methods:
    1. The minimum that applies to the average piece weight for the entire mailing is used. The net weight of the mailing is divided by the number of pieces, and the resulting average single-piece weight is used to determine whether the 125-piece or 15-pound minimum applies.
    2. The actual piece count or mail weight for each tray is used, if documentation can be provided with the mailing that shows for each tray the number of pieces and the total weight.
8.5 Drop Shipment

A mailer using Priority Mail or Priority Mail Express to drop ship USPS Marketing Mail flat-size pieces may prepare flat trays/sacks containing fewer than 125 pieces or less than 15 pounds of mail.

8.6 Traying, Sacking, and Labeling

[7-14-24] Flat trays are allowed for all sortations. Sack preparation is allowed only for the following: Nonpalletized residual 5-digit flats entered at a DDU/S&DC along with carrier-route flats; Nonpalletized carrier-route flats entered at the DSCF/LPC (origin); Nonpalletized 5-digit flats entered at the DSCF/LPC (origin); and nonpalletized 3-digit flats entered at the DSCF/LPC (origin). DSCF/LPC (origin) 5-digit and 3-digit/SCF sacks must be entered at the BMEU and emptied into a designated container. All other sortations require flat-tray preparation. Preparation sequence and labeling:

  1. 5-digit/scheme (required); scheme sort required (before 5-digit sort), only for pieces meeting the automation flats criteria in 201.6.0, see definition in 1.4j; full flat tray; 125-piece, or 15-pound minimum; labeling:

  5. Sortation determines price eligibility as specified in 243.5.0.
9.2 Residual Pieces

Pieces not sorted as a carrier route mailing must be prepared as a separate mailing at USPS Marketing Mail automation or Presorted prices or at the applicable single-piece First-Class Mail or USPS Ground Advantage — Retail prices.

9.3 Carrier Route Bundle Preparation

Prepare carrier route bundles of flat-size mail as follows:

  1. Mailers must prepare only carrier route bundles. Carrier route bundles are not required in full carrier route trays.
  2. Except under 9.4, carrier route bundles must contain at least 10 pieces.

When traying/sacking is required, mailers must prepare a flat tray/sack when the quantity of mail for a required presort destination reaches up to the handholds (see 1.4), 125 pieces or 15 pounds of pieces (sacks), whichever occurs first. The following conditions apply:

  1. For identical-weight pieces, a single-piece weight of 1.92 ounces (0.12 pound) results in 125 pieces weighing 15 pounds. Identical-weight pieces weighing 1.92 ounces (0.12 pound) or less must be prepared using the 125-piece minimum; those that weigh more must be prepared using the 15-pound minimum.
  2. For nonidentical-weight pieces, mailers must use one of the following:
    1. The minimum that applies to the average piece weight for the entire mailing. Divide the net weight of the mailing by the number of pieces; the resulting average single-piece weight determines whether the 125-piece or 15-pound minimum applies; or
    2. Tray/sack by the actual piece count or mail weight for each flat tray/sack, if documentation can be provided with the mailing that shows (specifically for each flat tray/sack) the number of pieces and their total weight.

  3. 5-digit carrier routes: required (no minimum).
    1. Line 1: city, state, and 5-digit ZIP Code on mail (see 203.5.11 for overseas military mail).
    2. Line 2: “STD FLTS CR-RTS.”
9.8 Merged Containerization of Carrier Route, Automation, and Presorted Price Flats

Under the optional preparation in 705.10.0, carrier route price bundles prepared under 9.3 and 9.4 are cotrayed with Presorted price 5-digit bundles prepared under 8.0 and with automation price 5-digit bundles prepared under 10.0 in merged 5-digit scheme flay trays and merged 5-digit flat trays. Under the optional preparation in 705.10.0, 705.12.0, or 705.13.0, carrier route price bundles prepared under 9.3 and 9.4 are copalletized with Presorted price 5-digit bundles prepared under 8.0 and with automation price 5-digit bundles prepared under 10.0 on merged 5-digit scheme pallets and merged 5-digit pallets. Presorted price pieces may be cobundled with automation price pieces under 705.11.0.

9.9 Delivery Sequence Standards
9.9.1 Basic Standards

Mailpieces for which a walk-sequence discount is claimed must be organized in the delivery sequence determined by the USPS and prepared as a carrier route mailing under 9.0 and the standards below. Pieces prepared with a simplified address must also meet the corresponding standards.

9.9.2 Missing Addresses

Some mailpieces cannot be sequenced because an exact match for a name or address cannot be obtained. These pieces may be included in a sequenced mailing only if they are placed behind or after the sequenced mail. Arrange these pieces:

  1. Alphabetically by complete street name, then either in ascending order by ZIP+4 code sector segments or numerically in ascending order by primary address.
  2. Numerically for numbered streets, then either in ascending order by ZIP+4 code sector segments or numerically in ascending order by primary address.
9.9.3 Updating Walk Sequence Information—General

Walk-sequence price pieces prepared with other than a simplified address format under 9.9.4 must be sequenced using USPS data from one of the following sources, issued within 90 days before the mailing date:

  1. The Computerized Delivery Sequence (CDS) file.
  2. The Delivery Sequence File, Second Generation (DSF2).
  3. Delivery sequence information from USPS address sequencing services, as requested by the customer.
9.9.4 Updating Delivery Statistics Information for Simplified Addressing

Mailpieces with a simplified address, prepared for distribution to rural or highway contract routes or to PO boxes in a Post Office without city delivery, must be based on delivery stop information obtained within 90 days before the mailing date, either from the Delivery Statistics File, in accordance with 509.1.11, or from the postmaster of the destination office. Mailpieces with a simplified address, prepared for distribution to city routes or to PO boxes in a Post Office with city delivery, must be based only on delivery stop information obtained from the Delivery Statistics File, in accordance with 509.1.11, within 90 days before the mailing date.

9.9.5 Out-of-Date Walk Sequence Information

Mailings prepared with out-of-date walk-sequencing or delivery statistics information are not eligible for prices requiring walk-sequence preparation.

9.9.6 Updating Line-of-Travel Sequence Information

Unless the mail is prepared in carrier walk sequence, line-of-travel (LOT) sequence is required for mailings at USPS Marketing Mail Enhanced Carrier Route basic prices. LOT sequence is not an exact walk sequence but a sequence of ZIP+4 codes arranged in the order that the route is served by a carrier. (First the ZIP+4 groups are sequenced, then the addresses within each are identified as being in ascending or descending order.) The USPS eLOT product provides a list of the ZIP+4 codes each carrier route serves, identifies the order in which they are delivered, and provides an indicator specifying whether the addresses that share the same ZIP+4 code must be sorted in ascending or descending order. When a range of ZIP+4 codes on the same carrier route are assigned the same sequence number, the addresses bearing those ZIP+4 codes must be arranged in ascending ZIP+4 code order before the sequence number is assigned. LOT information must be updated within 90 days before the date of mailing.

9.10 Delivery Sequence Documentation
9.10.1 Basic Standards

[1-21-24] The postage statement must be annotated in the “Carrier Route Sequencing Date” block on page 1. The mailer must annotate the postage statement to show the earliest (oldest) date of the method used to obtain sequencing information for the mailing. The mailer’s electronic confirmation during eDoc submission certifies that this standard has been met when the corresponding mail is presented to USPS. The mailer must maintain documentation to substantiate compliance with the standards for carrier route sequencing. Unless submitted with each corresponding mailing, the mailer must be able to provide the USPS with documentation (if requested) of accurate sequencing or delivery statistics for each carrier route to which pieces are mailed. Acceptable forms of documentation are:

  1. The invoice showing that the addresses came from CDS.
  2. DSF2 invoice or documentation.
  3. Copies of the delivery unit summaries that served as the mailer‘s bills for address sequencing service charges.
  4. Evidence of receipt of information from postmasters for simplified address mailings (see 509.1.0).
  5. Form 3553 showing the date of the eLOT product used, or the date from the USPS Qualification report produced by presort software.
9.10.2 High Density and High Density Plus

For each carrier route to which high density or high density plus mail is addressed, the mailer must document the total number of addressed pieces to the route.

9.10.3 Saturation Density—Simplified Address Mail

For each carrier route to which mail with a simplified address is sent at the saturation price, the mailer must be able to document that the mailing meets the applicable density standard. This documentation must show the total number of active possible deliveries and the total number to which mailpieces in the mailing are being addressed, by 5-digit ZIP Code and, within each, by carrier route. It must be submitted with each applicable mailing.

9.10.4 Saturation Density—Other Mail

For each carrier route to which mail without a simplified address is sent at the saturation price, the mailer must be able to document that the mailing meets the applicable density standards. This documentation must show either the total number of active possible residential deliveries and the number and percentage to which mailpieces are addressed, or the total number of all active possible deliveries and the number and percentage to which mailpieces are addressed, depending on whether qualification is based on the 90% or 75% criterion, respectively. The documentation must be listed by 5-digit ZIP Code and, within each, by carrier route. It must be submitted with each applicable mailing.

9.10.5 Both Prices

If a mailing contains pieces qualifying for more than one walk-sequence price, the documentation required by 9.10.2, 9.10.3, or 9.10.4 may be combined. Entries for pieces at the high density or high density plus prices must be so annotated on the documentation. For the entire mailing, a summary of the total number of pieces at each price must be provided. This documentation must be submitted with each mailing.

9.10.6 Carrier Route Price

If a mailing includes walk-sequence price and basic carrier route price pieces, in addition to the information required by 9.10.2 through 9.10.5, the documentation for the basic carrier route price mail must show, by 5-digit ZIP Code and, within each, by carrier route, the total number of addressed pieces at each price for each carrier route to which pieces are addressed. Pieces qualifying for the basic carrier route price must be so annotated. For the entire mailing, a summary by 5-digit ZIP Code of the total number of pieces at each price must be provided. This documentation must be submitted with each mailing.
