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. [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, enhanced carrier route) 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. Standard Mail. Except as provided in 243.3.4, Residual Volume Requirement, the types of Standard Mail listed below may not be part of the same mailing.
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.
c. 5‑digit scheme (trays) for automation letters: the ZIP Code in the delivery address on all pieces is one of the 5‑digit ZIP Code areas processed by the USPS as a single scheme, as shown in the USPS City State Product.
d. 3‑digit: the ZIP Code in the delivery address on all pieces begins with the same three digits (see L002, Column A).
e. 3‑digit scheme: the ZIP Code in the delivery address on all pieces begins with one of the 3‑digit prefixes processed by the USPS as a single scheme, as shown in L003.
f. Origin/optional entry 3‑digit(s): the ZIP Code in the delivery address on all pieces begins with one of the 3‑digit prefixes processed at the sectional center facility (SCF) in whose service area the mail is verified/entered. Subject to standard, a separation is required for each such 3‑digit area regardless of the volume of mail.
g. 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.
h. Origin/optional entry SCF: the separation includes bundles for one or more 3‑digit areas served by the same sectional center facility (SCF) (see L002, Column C, or L005) in whose service area the mail is verified/entered. Subject to standard, this separation is required regardless of the volume of mail.
l. Residual pieces/bundles 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. 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 rate claimed.
d. 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 rate claimed.
e. A 5‑digit scheme sort for automation letters yields 5‑digit scheme trays for those 5‑digit ZIP Codes identified in the USPS City State Product and 5‑digit trays for other areas. Mail prepared using 5‑digit scheme sort must be entered no later than 90 days after the release date of the City State Product used to obtain the scheme information (see 708.3.0, Coding Accuracy Support System (CASS)). 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 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 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 rate eligibility, and need not be used for all 5‑digit ZIP Codes that are part of a scheme.
f. A 3‑digit scheme sort 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.
g. An origin 3‑digit (or origin 3‑digit scheme) tray 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 must be prepared for each.
h. 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.
i. 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.
j. 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.
k. 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.
l. 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. The term bundle does not apply to unsecured groups of pieces (e.g., pieces prepared in trays and identified by separator cards or tic marks). Bundle preparation is described in 2.0.
m. A tic mark is defined as a solid black rectangle that must be printed on both the front side (extending over the top) and back side (flap side) of the envelope. Tic marks may be used in lieu of separator cards for Standard Mail automation mailings and separator cards or rubber bands in Standard Mail nonautomation carrier route mailings prepared in full 5‑digit carrier routes trays. Tic marks must be printed on the top edge of the first mailpiece in each carrier route grouping during the mailpiece production process and must meet the following specifications:
2. Reflectance and Contrast Ratio: The tic mark must meet the reflectance and contrast ratio specifications in 708.4.3, Reflectance.
3. Location: The tic mark must extend along the top edge of the envelope, to the left of center line of the envelope. Its location must be referenced to the center line. The right edge of the tic mark must be 0.5 inch (+ 0.125 inch) from the center line of the envelope.
4. Size: The width of the tic mark must be 0.5 inch (+ 0.125 inch). The tic mark must extend over the top of the envelope, down each side a distance of 0.25 inch (+ 0.125 inch). When a second tic mark is used to indicate a tray break at the end of the tray, all specifications are the same as for one tick mark, except for the location on the envelope. When a second tic mark is used on the last piece in a tray to indicate a tray break, the right edge of the second tic mark must be 0.5 inch
n. 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., tray, 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 Standard Mail "logical" 5‑digit bundle, and they are prepared in three physical 5‑digit bundles because of the applicable restrictions on bundles. [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. The term bundle does not apply to unsecured groups of pieces (e.g., pieces prepared in trays and identified by separator cards or tic marks). [M011.1.3z]
c. Bundles must be prepared for mail in all less‑than‑full trays and 3‑digit carrier routes trays; for nonmachinable Presorted Standard Mail; and for Standard Mail pieces where the mailer has requested "manual only" processing.
d. Separator cards or tic marks may be used instead of bundling for letter‑size pieces in full 5‑digit carrier routes trays of Enhanced Carrier Route Standard Mail. Separator cards or tic marks must be used instead of bundling for letter‑size pieces in full 5‑digit trays of automation Enhanced Carrier Route Standard Mail. The cards must be of paper or card stock, at least 0.25 inch higher than the highest pieces in the mailing, and in front of the corresponding groups of mail. The tic mark must be applied during the mailpiece production process and be printed on the top edge of the envelope, to the left of the center line of the envelope.
e. For mailings consisting entirely of card‑size pieces and mail in less‑than‑full trays, bundles must be secured with rubber bands, elastic strapping, flat plastic strapping, or string. (Elastic strapping must have a minimum strength of 15 pounds and a minimum of 150% elongation before breaking. Minimum tension, when applied to the bundle, must be 50% breaking strength. Elastic strapping may not be used unless approved by USPS Engineering. If requested, the mailer must be able to show such approval for the strapping material used for a mailing.)
f. Bundles up to 1 inch thick must be secured with appropriate banding placed once around the girth (narrow dimension). Bundles over 1 inch thick must be secured with at least two bands, one around the length and one around the girth. [M020.2.1]
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. 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.
In bundle‑based mailings not entirely of card‑size pieces (i.e., pieces not larger than 4‑1/4 by 6 by 0.016 inch), mail need not be prepared in 5‑digit bundles if placed in a full 5‑digit tray. Similarly, mail need not be prepared in other levels of bundles when it will be placed in a full tray to the corresponding tray level, and none of the mail in that tray would have been more finely sorted if bundled. For example, the content of a full ADC tray need not be bundled if, when correctly sorted, it would have all been prepared in ADC bundles to the same destination; conversely, this exception would not apply if some pieces would require preparation in 5‑digit or 3‑digit bundles. [M020.1.9]
For mail prepared with a simplified address, all pieces for the same post office must be prepared in bundles of 50 when possible. If bundles of other quantities are prepared, the actual number of pieces must be shown on the facing slip attached to show distribution desired (e.g., rural route, city route, post office boxholder). Bundles must be secure subject to specific thickness limits in 707.19.5, Letter‑Size Bundles, for cards and letter‑size pieces. [M020.2.3]
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 28 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]
Unless excepted by standard, the presort level of each bundle (other than carrier route bundles) must be identified either with an optional endorsement line under 708.7.0 or with a barcoded pressure‑sensitive bundle label. On letter‑size mail (including card‑size pieces), the bundle label must be placed in the lower left corner of 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 under 708.7.0. [M013.1.1]
Bundles for individual carrier routes, rural routes, highway contract routes, post office box sections, or general delivery units must be prepared with facing slips under 2.0, optional endorsement lines under 708.7.0, or carrier route information lines under 708.6.0. These standards apply to Enhanced Carrier Route Standard Mail mailings. Carrier route information lines may be on all pieces in a mailing, regardless of presort level. [M014.1.0]
Mailings must be prepared in letter trays with sleeves. Containers for Customized MarketMail are specified in 705.1.4. The following additional standards apply:
a. Palletized mail is also subject to 705.8.0.
b. A postmaster may authorize nonpostal containers for a small‑volume presorted mailing if the mailing weighs no more than 20 pounds, consists primarily of mail or bundles of mail for local ZIP Codes, and requires no USPS transportation for processing. [M033.1.2]
a. Subject to availability of equipment, standard managed mail (MM) trays must be used for all letter‑size mail, except that extended managed mail (EMM) trays must be used when available for letter‑size mail that exceeds the inside dimensions of MM trays defined in 3.2. When EMM trays are not available for those larger pieces, they must be placed in MM trays, angled back, or placed upright perpendicular to the length of the tray in row(s) to preserve their orientation.
c. Each tray prepared must be filled before filling the next tray, with the contents in multiple trays relatively balanced. When preparing full trays, mailers must fill all possible 2‑foot trays first; if there is mail remaining for the presort destination, mailers must use a combination of 1‑foot and 2‑foot trays that results in the fewest total number of trays for that presort level. As an alternative, if there is mail remaining, mailers may move those pieces to the next higher presort level at which there is a minimum quantity (e.g., 150 pieces).
e. Mailers must use as few trays as possible without jeopardizing rate eligibility. For instance, a mailer will never have two 1‑foot trays to a single destination; instead, that mail must be placed in a single 2‑foot tray. A 1‑foot tray is prepared only if it is a full tray with no overflow; or if there is less than 1 foot of mail for that destination; or if the overflow from a full 2‑foot tray is less than 1 foot of mail.
h. If a mailing is prepared using an MLOCR/barcode sorter and is submitted with standardized documentation, then pieces do not have to be grouped by 3‑digit ZIP Code prefix (or by 3‑digit scheme, if applicable) in AADC trays, or by AADC in mixed AADC trays. [M033.2.1]
Each letter tray must be sleeved using USPS‑provided sleeves. Except under 3.5, each sleeved letter tray must then be secured with one plastic strap placed tightly around the length of the tray without crushing the tray or sleeve. [M033.1.5]
Strapping is not required for any letter tray placed on a 5‑digit, 3‑digit, or SCF pallet secured with stretchwrap. In addition, if the processing and distribution manager gives a written waiver, strapping is not required for any letter tray that originates and destinates in the same SCF (mail processing plant) service area. [M033.1.6]
After all finer sort levels are prepared, an origin/entry 3‑digit tray (or, if applicable, origin/entry 3‑digit scheme tray) must be prepared to contain any remaining mail for each 3‑digit (or 3‑digit scheme) area serviced by the SCF serving the post office where the mail is verified (origin), and may be prepared for each 3‑digit (or 3‑digit scheme) area served by the SCF/plant where mail is entered (if that is different from the SCF/plant serving the post office where the mail is verified—e.g., a PVDS deposit site). In all cases, only one less‑than‑full tray may be prepared for each 3‑digit (or 3‑digit scheme) area. [M033.1.7]
Only tray labels may be used for trays. Machine‑printed labels (available from the USPS) ensure legibility. Legible hand‑printed labels are acceptable. Illegible labels are not acceptable. Container labels for automation rate mailings are subject to 4.9, Barcoded Tray Labels, and 708.6.0. [M031.1.1]
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 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 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 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]
A tray label must be securely placed in an adhesive‑backed label holder that is affixed to the specific location designated on the tray. Where no specific location is indicated the label must be securely placed in an adhesive‑backed label holder that is affixed horizontally to the top left corner of one end of the tray. Do not use tape. Insert labels completely into the label holder to ensure that they do not fall out during processing. Do not insert labels upside down. [M031.3.1]
Exhibit 4.9.1, Required Barcoded Container Labels, shows the types of mail requiring barcoded tray labels. Barcoded labels must meet these general standards:
b. Mailer‑produced barcoded labels must meet the standards in 708.6.0.
b. Reflectance: minimum reflectance requirements in 708.6.2i..
All mailings and all pieces in each mailing at Regular Standard Mail and Nonprofit Standard Mail nonautomation rates are subject to specific preparation standards in 5.0 and to these general standards (automation rate mailings must be prepared under 7.0):
c. All pieces must meet the applicable general preparation standards in 202, Elements on the Face of a Mailpiece.
d. All pieces in the mailing must meet the specific sortation and preparation standards in 5.0.
e. Sortation determines rate eligibility as specified in 243.5.0, Additional Eligibility Standards for Presorted Standard Mail Letters. [M610.1.1]
Subject to the marking standards in 202.3.0, Placement and Content of Mail Markings, and 202.4.0, Endorsement Placement, regular Standard Mail pieces must be marked "Presorted Standard" (or "PRSRT STD") and Nonprofit Standard Mail pieces must be marked "Nonprofit Organization" (or "Nonprofit Org." or "Nonprofit"). Regular and Nonprofit Standard Mail pieces must not be marked "ECRLOT," "ECRWSH," "ECRWSS," "AUTO," "AUTOCR," or "Single‑Piece" (or "SNGLP"). [M610.1.1b1]
Mailers who prefer that the USPS not automate letter‑size pieces (including cards) must use the bundling and tray preparation sequence for nonmachinable pieces in 3.5, Strapping Exception, and 3.4, Tray Sleeving and Strapping. [M610.1.6]
Machinable pieces are not bundled, except for (see 707.19.0, Bundles):
1. Line 1: city, state, and 5‑digit ZIP Code on mail, preceded for military mail by correct prefix under 4.0, Tray Labels.
1. Line 1: L002, Column A.
1. Line 1: L002, Column A.
1. Line 1: L801, Column B.
Except as provided in 2.5, Exception to Bundle Preparation—Full Single‑Sort‑Level Trays, 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. Mailers who prefer that the USPS not automate letter‑size pieces must also identify each bundle with a facing slip marked "MANUAL ONLY" or use a "MANUAL ONLY" optional endorsement line (see 708.7.0). Preparation sequence, bundle size, and labeling:
1. Line 1: city, state, and 5‑digit ZIP Code on mail (see 4.0, Tray Labels, for overseas military mail).
1. Line 1: L002, Column A.
1. Line 1: L002, Column A.
1. Line 1: L004, Column B.
1. [03-17-05] [02-03-05] Line 1: "MXD" followed by city, state, and ZIP Code of ADC serving 3‑digit ZIP Code prefix of entry post office, as shown in L004. If placed on an ASF or BMC pallet under option in 705.8.10.2, use L010.
All mailings and all pieces in each mailing at Enhanced Carrier Route Standard Mail and Nonprofit Enhanced Carrier Route Standard Mail nonautomation rates are subject to specific preparation standards in 6.0 and to these general standards (Enhanced Carrier Route automation rate mailings must be prepared under 7.0):
a. All pieces must meet the standards for basic eligibility in 243.2.0 through 243.4.0 and specific eligibility in 243.6.0, Additional Eligibility Standards for Enhanced Carrier Route Standard Mail. Nonprofit Enhanced Carrier Route Standard Mail must meet the additional eligibility standards in 703.1.0.
1. Pieces must be sequenced according to 6.9, Delivery Sequence Standards.
2. Pieces with a simplified address format must meet the standards in 602.3.0, Use of Alternative Addressing.
e. Sortation determines rate eligibility as specified in 243.6.0, Additional Eligibility Standards for Enhanced Carrier Route Standard Mail. [M620.1.1]
Subject to the marking standards in 202.3.0, Placement and Content of Mail Markings, and 202.4.0, Endorsement Placement, Enhanced Carrier Route Standard Mail pieces must be marked "Presorted Standard" (or "PRSRT STD"), and Nonprofit Enhanced Carrier Route Standard Mail pieces must be marked "Nonprofit Organization" (or "Nonprofit Org." or "Nonprofit"). All pieces must also be marked "ECRLOT" for basic rate, "ECRWSH" for high density rate, or "ECRWSS" for saturation rate. [M620.1.1c1]
As a general exception to 6.4 and 6.6, a bundle with fewer than 10 pieces and a less‑than‑full tray may be prepared to a carrier route when the saturation rate is claimed for the contents and the applicable density standard is met. [M620.1.3]
b. Bundles in 5‑digit carrier routes trays and in 3‑digit carrier routes trays must have a facing slip unless the pieces in the bundle show a carrier route information line or an optional endorsement line. [M620.2.2]
1. Line 1: city, state, and 5‑digit ZIP Code on mail (see 4.0, Tray Labels, for overseas military mail).
2. Line 2: (a) Saturation: "STD LTR BC WSS," followed by route type and number; (b) High density: "STD LTR BC WSH," followed by route type and number; (c) Basic: "STD LTR BC LOT," followed by route type and number.
1. Line 1: city, state, and 5‑digit ZIP Code on mail (see 4.0, Tray Labels, for overseas military mail).
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.
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 6.8 in Preparation for Enhanced Carrier Route Letters and the standards below. Pieces prepared with a simplified address must also meet the corresponding standards.
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:
Walk‑sequence rate pieces prepared with other than a simplified address format under 6.9.4 must be sequenced using USPS data from one of the following sources, issued within 90 days before the mailing date:
Walk‑sequence rate pieces prepared with a simplified address must be based on delivery stop information obtained within 90 days before the mailing date, either from the Delivery Statistics File or from the postmaster of the destination office. [M050.2.1]
Unless the mail is prepared in carrier walk sequence, line‑of‑travel (LOT) sequence is required for mailings at Standard Mail Enhanced Carrier Route basic rates. 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. [M050.2.4]
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 signature on the postage statement certifies that this standard has been met when the corresponding mail is presented to the 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:
d. Evidence of receipt of information from postmasters for simplified address mailings (see 509.1.0, Address Information System Products).
For each carrier route to which high density rate mail is addressed, the mailer must document the total number of addressed pieces to the route. If there are fewer than 125 addressed pieces for a given route, the documentation also must show the number of possible deliveries on the route. [M050.3.2]
For each carrier route to which mail with a simplified address is sent at the saturation rate, 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. [M050.3.3]
For each carrier route to which mail without a simplified address is sent at the saturation rate, 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. [M050.3.4]
If a mailing contains pieces qualifying for both walk‑sequence rates, the documentation required by 6.10.2, High Density, and either 6.10.3, Saturation Density—Simplified Address Mail, or 6.10.4, Saturation Density—Other Mail, may be combined. Entries for pieces at the high density rate must be so annotated on the documentation. For the entire mailing, a summary of the total number of pieces at each rate must be provided. This documentation must be submitted with each applicable mailing. [M050.3.5]
If a mailing includes high density and saturation rate and basic carrier route rate pieces, in addition to the applicable information required by 6.10.2 through 6.10.5 in Delivery Sequence Documentation, the documentation for the basic carrier route rate mail must show, by 5‑digit ZIP Code and, within each, by carrier route, the total number of addressed pieces at each rate for each carrier route to which pieces are addressed. Pieces qualifying for the basic carrier route rate must be so annotated. For the entire mailing, a summary by 5‑digit ZIP Code of the total number of pieces at each rate must be provided. This documentation must be submitted with each applicable mailing to meet the documentation standard for the carrier route rate. [M050.3.6]
a. General.
