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 rate 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. Not all presort levels are applicable in all situations. [M011.1.1]
a. 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.
b. 3‑digit: the ZIP Code in the delivery address on all pieces begins with the same three digits (see L002, Column A).
c. 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.
d. ADC: all pieces are addressed for delivery in the service area of the same area distribution center (ADC) (see L004).
g. Residual pieces/bundles/sacks contain material remaining after completion of a presort sequence. Residual mail lacks the volume set by standard to require or allow bundle preparation to a particular destination, and usually does not qualify for a presort rate. Residual mail is also referred to as nonqualifying or working mail. [M011.1.2]
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.
c. 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 rate 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 rate.
d. 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 rate eligibility standards. Standards for quantities with which preparation is optional are often followed by standards for larger quantities with which preparation is required.
e. Entry [facility] (or origin [facility]) refers to the USPS mail processing facility (e.g., "entry BMC") 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 BMC includes subordinate ASFs unless otherwise specified.
f. A bundle is a group of addressed pieces secured together as a unit. The presort process considers the total number of pieces available for the particular presort destination and assembles them into groups meeting applicable volume and size standards. When the standards for the rate claimed require securing the pieces in each group together, the result is a bundle. Bundle preparation is described in 2.0, Bundles.
g. 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 (i.e., sack, pallet) due to applicable preparation requirements or the size of the individual pieces. [M011.1.3]
A bundle is a group of addressed pieces secured together as a unit. The presort process considers the total number of pieces available for the particular presort destination and assembles them into groups meeting applicable volume and size standards. When the standards for the rate claimed require securing the pieces in each group together, the result is a bundle. [M011.1.3z]
c. When counter‑stacking, pieces must all have addresses facing up and be divided into no more than four approximately equal groups, with each group rotated 180 degrees from the preceding and succeeding group(s); prepare as few groups as possible to create a bundle of uniform thickness.
e. When pieces are nonuniform in thickness because they are thicker in the center instead of along an edge or corner, counter‑stacking will generally not result in a bundle of uniform thickness (i.e., a football‑shaped bundle would be created). Instead of counter‑stacking such pieces, limit the height (thickness) of the bundle to 3 to 6 inches to ensure the bundle will stay together during normal transit and handling. [M020.1.2]
b. Bundles must be secured with banding, shrinkwrap, or shrinkwrap plus one or more bands. Banding includes plastic bands, rubber bands, twine/string, and similar material. Use of wire or metal banding is not permitted.
d. Except under 705.8.5.11, Bundles on Pallets, bundles over 1 inch high (thick) must be secured with at least two bands or with shrinkwrap. When double banding is used to secure bundles, it must encircle the length and girth of the bundle at least once. Additional bands may be used if none lies within 1 inch of any bundle edge.
a. If placed on pallets, the specific weight limits in 705.8.0, Preparation for Pallets.
b. If placed in sacks, Library Mail must meet the specific weight limits in 5.2. [M020.2.2]
Each logical bundle (the total group of pieces for a bundle destination) of Library Mail must meet the applicable minimum and maximum bundle size standards in 5.2. The pieces in the logical bundle must then be secured in a physical bundle or bundles. Wherever possible, each physical bundle for a logical bundle destination should contain at least the minimum bundle size. The size of each physical bundle for a specific logical bundle destination may, however, contain the exact bundle minimum, more pieces than the bundle minimum, or fewer pieces than the bundle minimum depending on the size of the pieces in the mailing or the total quantity of the pieces to that destination. Unless otherwise noted, the maximum weight for bundles in sacks is 20 pounds. Bundles prepared on pallets must meet the additional bundling requirements under 705.8.0 and each physical bundle, including carrier route rate mail, must always contain at least two pieces. [M020.1.6]
a. A greater number of pieces would exceed the maximum physical size for a bundle and the total number of pieces for that presort destination meets the minimum volume standard (e.g., 30 pieces are available to meet a 10‑piece minimum, but a bundle of eight pieces is 6 inches thick).
b. The pieces constitute the "last bundle" for a presort destination and previously prepared bundles met the applicable minimum volume standard (e.g., 505 pieces prepared in 10 50‑piece bundles and one five‑piece bundle). [M020.1.7]
The presort level of each bundle must be identified either with an optional endorsement line under 708.7.0 or with a barcoded pressure‑sensitive bundle label. The label may be placed anywhere on the address side of the top piece in the bundle. Bundle labels must not be obscured by banding or shrinkwrap. The following colors and presort characters apply to bundle labels:
An optional endorsement line (OEL) may be used to label bundles instead of applying pressure‑sensitive bundle labels or facing slips to the top piece of bundles under 708.7.0. [M013.1.1]
a. Placement. Line 1 must be the first visible line on the label. It must be completely visible and legible when placed in the label holder. This visibility is ensured if the top of this line is no less than 1/8 (0.125) inch below the top of the label when the label is cut and prepared.
b. Information. Line 1 must contain only the information specified by standard, including the appropriate destination facility prefix (e.g., "ADC"). Two zeros may follow the 3‑digit ZIP Code prefix required by labeling standards (e.g., 223 as 22300).
c. Overseas Military Mail. On 5‑digit sacks and trays for overseas military destinations, Line 1 shows, from left to right, "APO" or "FPO," followed by "AE" (for ZIP Codes within the ZIP Code prefix range 090‑098), "AA" (for ZIP Codes within the 3‑digit ZIP Code prefix 340), or "AP" (for ZIP Codes within the ZIP Code prefix range 962‑966), followed by the destination 5‑digit ZIP Code of the mail in the sack or tray. [M031.1.2]
a. Placement: Line 2 must be the second visible line on the label. This line must show the class and processing category of the mail in the sack or tray and other information as specified by standards. [M031.1.3]
Line 3 (office of mailing or mailer information line) must be the bottom line of required information and must show either the city and state of the entry post office or the mailer's name and the city and state of the mailer's location. It is recommended that the mailer's name also appear with the city and state of the entry post office. [M031.1.4]
Lines 1 and 3 may contain abbreviated information if such abbreviations are those in the USPS City State Product or in Publication 65, National Five‑Digit ZIP Code and Post Office Directory. [M031.1.6]
b. Mailer‑produced barcoded labels must meet the standards in 708.6.0, Barcoding Standards for Container Labels.
b. Reflectance: minimum reflectance requirements in 708.6.3.3i., Barcode.
a. Each mailing must meet the applicable standards in 5.0.
c. Each piece claimed at Library Mail rates must be marked "Library Mail" under 302.2.0, Placement and Content of Mail Markings. Each piece claimed at Presorted Library Mail rates also must be marked "Presorted" or "PRSRT" under 302.2.0. [M740.1.1]
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. The maximum weight of each physical bundle is 20 pounds, except that 5‑digit bundles, placed in 5‑digit sacks may weigh a maximum of 40 pounds. Each physical bundle must contain at least two addressed pieces. [M740.2.1]
A sack must be prepared when the quantity of mail for a required presort destination reaches the minimums specified in 5.3.2 or 1,000 cubic inches. Smaller volumes are not permitted (except in mixed ADC sacks). [M740.2.3]
