465 Mail Preparation

1.0 General Information for Mail Preparation

1.1 Basic Preparation—Nonpresorted

There are no presort, sacking, or labeling standards for nonpresorted price Bound Printed Matter.

1.2 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.

1.3 Definition of Mailings

A mailing is a group of pieces within the same class of mail and, except for certain parcel prices, 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.

1.4 Terms for Presort Levels

Terms used for presort levels are defined as follows:

a. Carrier route: all pieces for delivery to the same city route, rural route, highway contract route, Post Office box section, or general delivery unit.

b. 5-digit: the delivery address on all pieces includes the same 5-digit ZIP Code.

c. 5-digit scheme (pallets and sacks) for Bound Printer Matter parcels: the ZIP Code in the delivery address on all pieces begins with one of the 5-digit ZIP Code ranges processed by the USPS as a single scheme, as shown in L606.

d. 3-digit: the ZIP Code in the delivery address on all pieces begins with the same three digits (see L002, Column A).

e. SCF: the separation includes pieces for two or more 3-digit areas served by the same sectional center facility (SCF) (see L005), except that, where required or permitted by standard, mail for a single 3-digit area may be prepared in an SCF separation when no mail for other 3-digit ZIP Code areas is available. For pallets, the SCF sort may include mail for a single 3-digit ZIP Code area.

f. ADC: all pieces are addressed for delivery in the service area of the same area distribution center (ADC) (see L004).

g. ASF/NDC: all pieces are addressed for delivery in the service area of the same auxiliary service facility (ASF) or network distribution center (NDC) (see L601, L602, or L605).

h. Mixed [NDC, ADC, etc.]: the pieces are for delivery in the service area of more than one NDC, ADC, etc.

1.5 Preparation Definitions and Instructions

For purposes of preparing mail:

a. Pieces refers to individually addressed mailpieces. This definition also applies when pieces is used in eligibility standards. Quantities indicated for optional or required sortations always refer to pieces unless specifically excepted.

b. A full sack is defined in the standards for the class and price claimed.

c. A 5-digit scheme sort for Bound Printed Matter 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. The 5-digit scheme sort is always optional, including when 5-digit sortation is required for price eligibility. The 5-digit scheme sort need not be used for all possible 5-digit scheme sorts.

d. An origin 3-digit (or origin 3-digit scheme) tray/sack contains all mail (regardless of quantity) for a 3-digit ZIP Code (or 3-digit scheme) area processed by the SCF in whose service area the mail is verified. If more than one 3-digit (or 3-digit scheme) area is served, as indicated in L005, a separate tray/sack must be prepared for each.

e. 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.

f. 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.

g. Entry [facility] (or origin [facility]) refers to the USPS mail processing facility (e.g., “entry NDC”) 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. Entry SCF includes both single-3-digit and multi-3-digit SCFs. Entry NDC includes subordinate ASFs unless otherwise specified.

h. The group pieces instruction means the pieces are to be sorted together as if to be bundled but not actually secured into a bundle. Bundle labels and other bundle identification methods may be used for unsecured groups of pieces as permitted by standard.

i. A bundle is a group of addressed pieces secured together as a unit. Bundle preparation is described in 2.0.

j. 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 (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 Bound Printed Matter “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 destination, and these would form the “logical” SCF pallet, but the mail is placed on two physical SCF pallets each weighing 1,400 pounds because of the 2,200 pound maximum pallet weight requirement.

5.0 Preparing Presorted Parcels

5.1 Basic Standards

5.1.1 General Preparation Requirements

All mailings of Presorted Bound Printed Matter (BPM) are subject to these general standards:

a. Each mailing must meet the applicable eligibility standards in 402.2.0, 463, 465, and 466,

b. All pieces in a mailing must be within the same processing category. See 401.1.0 for definitions of machinable and irregular parcels.

c. All pieces must be sorted to the finest extent possible under 5.2, and 5.3, or palletized under 705.8.0.

d. Subject to 402.2.0, pieces must be marked “Bound Printed Matter” (or “BPM”) and “Presorted” (or “PRSRT”).

5.1.2 Separation

Pieces for each zone must be sacked separately. When presented for verification, sacks must be separated by zone. Exception: Pieces for different zones may be sacked together, and the sacks do not have to be separated by zone for verification if the mailing is prepared under 705.2.0, 705.3.0, 705.4.0, or 5.1.3.

5.1.3 Commingling Zones

Subject to this section, when zoned BPM is presented as individual pieces, the mailing must be separated by zone. Nonidentical-weight pieces may not be commingled unless authorized by the BMS manager. The mail must be prepared and documented:

a. A unique number is assigned to each pallet in the mailing and printed on a separate line at the top of the pallet label (above the Line 1 information).

b. A detailed list accompanies each mailing or mailing segment, sequenced numerically by the numbers assigned to the pallets in the mailing, that shows the Post Office where the mail is to be entered (entry Post Office), a unique identifier for the mailing or mailing segment that also appears on the corresponding postage statement, the name and address of the mailer, the permit number, the date of mailing, individual line entries for each pallet, and the total number of pieces to each zone in the entire mailing or mailing segment. Line entries for pallets containing mail for only one zone must show the pallet number, the sortation level, the zone for which the mail is destined, and the total number of pieces for the pallet. Entries for pallets containing mail for more than one zone must also show (by zone) the number of pieces to each 3-digit ZIP Code area and the total number of pieces for that zone for the pallet. Mailings are not accepted if there are discrepancies between the information in the detailed listing or on the postage statement and the results of USPS random verification of piece counts and postage.

5.2 Preparing Irregular Parcels Weighing Less Than 10 Pounds

5.2.1 Required Bundling

Bundling is required before sacking, except for pieces placed in 5-digit scheme and 5-digit sacks when such pieces are enclosed in an envelope, full-length sleeve, full-length wrapper, or polybag and the minimum bundle size is met. Otherwise, a bundle must be prepared when the quantity of addressed pieces for a required presort level reaches a minimum of 10 pieces or 10 pounds, whichever occurs first. Smaller volumes are not permitted (except mixed ADC bundles). The maximum weight of each physical bundle is 20 pounds, except that 5-digit bundles placed in 5-digit scheme and 5-digit sacks or prepared for and entered at DDU prices may weigh a maximum of 40 pounds each. Each physical bundle must contain at least two addressed pieces (except mixed ADC bundles). Bundling also is subject to these conditions:

a. Identical-weight pieces that weigh 1 pound or less must be prepared using the 10-piece minimum; those that weigh more than 1 pound must be prepared using the 10-pound minimum.

b. For nonidentical-weight pieces, mailers must either use 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 10-piece or 10-pound minimum applies), or bundle by the actual piece count or mail weight for each sack, if documentation can be provided with the mailing that shows the number of pieces and their total weight.

c. Mailers must note on the postage statement whether they applied the piece count, weight, or both, except for eVS mailings prepared under 705.2.9.

5.2.2 Bundling and Labeling

Preparation sequence and labeling:

a. 5-digit (required); red Label 5 or optional endorsement line (OEL).

d. Mixed ADC (required); tan Label X or OEL.

5.2.3 Required Sacking

A sack must be prepared when the quantity of mail for a required presort destination reaches either 10 addressed pieces or 20 pounds, whichever occurs first. Smaller volumes are not permitted (except mixed ADC sacks). Optional SCF sacks may be prepared only when there are at least 10 addressed pieces or 20 pounds, whichever occurs first. Sacking is not required for 5-digit bundles when prepared for and entered at DDU prices. Such bundles may be bedloaded and may weigh up to 40 pounds. Sacking also is subject to these conditions:

a. Identical-weight pieces weighing 2 pounds or less must be prepared using the 10-piece minimum, those that weigh more must be prepared using the 20-pound minimum.

b. For nonidentical-weight pieces, mailers must use either 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 10-piece or 20-pound minimum applies). Alternatively, sack by the actual piece count or mail weight for each bundle destination, provided that documentation can be provided with the mailing that shows (specifically for each sack) the number of pieces and their total weight.

c. Mailers must note on the postage statement whether they applied the piece count or weight except for eVS mailings prepared under 705.2.9.

6.0 Preparing Carrier Route Parcels

6.1 Basic Standards

6.1.1 General Standards for Carrier Route Preparation

All mailings of Carrier Route Bound Printed Matter (BPM) are subject to the standards in 6.2 through 6.4 and to these general standards:

a. Each mailing must meet the applicable eligibility standards in 463, mail preparation standards in 2.0, through 4.0, and deposit and entry standards in 466.

b. All pieces in a mailing must be within the same processing category as described in 401.1.0. A BPM irregular parcel is a piece that is not a machinable parcel as defined in 401.1.5.1. Irregular parcels also are pieces that meet the size and weight standards for a machinable parcel but are not individually boxed or packaged to withstand processing on NDC parcel sorters under 601.7.0.

c. All pieces must be sorted to the finest extent possible under 6.0, or palletized under 705.8.0.

d. Subject to 402.2.0, pieces must be marked “Bound Printed Matter” (or “BPM”) and “Carrier Route Presort” (or “CAR-RT SORT”).

6.1.2 Separation

Pieces for each zone must be sacked separately. When presented for verification, sacks must be separated by zone. Exception: Pieces for different zones may be sacked together, and the sacks do not have to be separated by zone for verification if the mailing is prepared under 705.2.0, 705.3.0, 705.4.0, or 6.1.3.

6.1.3 Commingling Zones

Subject to this section, when zoned BPM is presented as individual pieces, the mailing must be separated by zone. Nonidentical-weight pieces may not be commingled unless authorized by the BMS manager. The mail must be prepared and documented:

a. A unique number is assigned to each pallet in the mailing and printed on a separate line at the top of the pallet label (above the Line 1 information).

b. A detailed list accompanies each mailing or mailing segment, sequenced numerically by the numbers assigned to the pallets in the mailing, that shows the Post Office where the mail is to be entered (entry Post Office), a unique identifier for the mailing or mailing segment that also appears on the corresponding postage statement, the name and address of the mailer, the permit number (if applicable), the date of mailing, individual line entries for each pallet, and the total number of pieces to each zone and in the entire mailing or mailing segment. Line entries for pallets containing mail for only one zone must show the pallet number, the sortation level, the zone for which the mail is destined, and the total number of pieces for the pallet. Entries for pallets containing mail for more than one zone must also show (by zone) the number of pieces to each 3-digit ZIP Code area and the total number of pieces for that zone for the pallet. Mailings are not accepted if there are discrepancies between the information in the detailed listing or on the postage statement and the results of USPS random verification of piece counts and postage.

6.1.4 Residual Pieces

Residual pieces not sorted under 6.2 and 6.3 may be prepared as a Presorted Bound Printed Matter mailing under 5.0, provided that they are part of the same mailing job and reported on the same postage statement. Residual pieces paid at the Presorted price do not need to meet a separate 300 piece minimum. These pieces must be separated from the Carrier Route portion when presented to the USPS for verification.

6.2 Preparing Irregular Parcels Weighing Less Than 10 Pounds

6.2.1 Bundle Preparation

Bundling is not required in direct carrier route sacks. Otherwise, a carrier route bundle (or bundles) must be prepared when the quantity of addressed pieces for a carrier route reaches a minimum of 10 pieces or 20 pounds, whichever occurs first. Smaller volumes are not permitted. The maximum weight of each physical bundle is 40 pounds. Each bundle must contain at least two addressed pieces except for the last bundle for each carrier route destination under 2.0. Bundles must be labeled with a facing slip unless the bundle is labeled using a carrier route information line (708.6.0) or an optional endorsement line (708.7.0). Bundling also is subject to these conditions:

a. Identical-weight pieces that weigh 2 pounds or less must be prepared using the 10-piece minimum; those that weigh more must be prepared using the 20-pound minimum.

b. For nonidentical-weight pieces, mailers must either use 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 10-piece or 20-pound minimum applies), or bundle by the actual piece count or mail weight for each bundle destination, provided that documentation can be provided with the mailing that shows (specifically for each bundle) the number of pieces and their total weight.

c. Mailers must note on the accompanying postage statement whether they applied the piece count, weight, or both.

6.2.2 Required Sacking

Mailers may prepare irregular parcels as unsacked bundles under 601.2.10 or in bundles on pallets. Otherwise, mailers must prepare a direct carrier route sack when the quantity of mail for an individual carrier route reaches either 10 addressed pieces or 20 pounds, whichever occurs first; smaller volumes are not permitted. Mailers then must place remaining bundles in 5-digit scheme carrier routes sacks or 5-digit carrier routes sacks, which have no minimum sack size. Carrier route sacks also are subject to these conditions:

a. Identical-weight pieces that weigh 2 pounds or less must be prepared using the 10-piece minimum; those that weigh more must be prepared using the 20-pound minimum.

b. For nonidentical-weight pieces, mailers must either use 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 10-piece or 20-pound minimum applies), or sack by the actual piece count or mail weight for each sack destination, provided that documentation can be provided with the mailing that shows (specifically for each sack) the number of pieces and their total weight.

c. Mailers must note on the accompanying postage statement whether they applied the piece count or weight.

6.4 Preparing Machinable Parcels

6.4.1 Required Carrier Route Sacking

Machinable parcels may be prepared only in direct carrier route sacks. Each carrier route sack must contain a minimum of 10 addressed pieces or 20 pounds, whichever occurs first. Carrier route sacks also are subject to these conditions:

a. Identical-weight pieces that weigh 2 pounds or less must be prepared using the 10-piece minimum; those that weigh more must be prepared using the 20-pound minimum.

b. For nonidentical-weight pieces, mailers must use either 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 10-piece or 20-pound minimum applies), or sack by the actual piece count or mail weight for each sack destination, provided that documentation can be provided with the mailing that shows (specifically for each sack) the number of pieces and their total weight.

c. Mailers must note on the accompanying postage statement whether they applied the piece count or weight.
