1.0 Prices and Fees for Standard Mail
1.1 Standard Mail Price Application
a. The appropriate minimum per piece price applies to any Standard Mail piece that weighs 3.3 ounces (0.2063 pound) or less.
b. A price determined by adding the per piece charge and the corresponding per pound charge applies to any Standard Mail piece that weighs more than 3.3 ounces.
1.2 Regular and Nonprofit Standard Mail—Presorted and Enhanced Carrier Route Prices
1.4.1 Annual Mailing Fee
1.4.2 Weighted Fee
For return of pieces bearing the ancillary service markings “Address Service Requested” and “Forwarding Service Requested.” Weighted fee equals single-piece First-Class Mail or Priority Mail price multiplied by 2.472.
1.5 Computing Postage for Standard Mail
a. Identical-weight pieces, multiply the computed average weight of a single piece by the corresponding number of pieces; do not round the product.
b. Nonidentical-weight pieces, add the actual weight of the individual pieces or weigh the entire mailing in bulk; do not round either result.
To determine single-piece weight in a mailing of identical-weight pieces, weigh a sample group of at least 10 randomly selected pieces and divide the total sample weight by the number of pieces in the sample. To determine single-piece weight in a mailing of nonidentical-weight pieces, weigh each piece individually. Express all single-piece weights in decimal pounds, rounded off to four decimal places.
1.5.3 Net Postage
Postage is computed at the applicable prices on the entire mailing to be mailed at one time. The net postage price is either the applicable minimum per piece price or the piece/pound price, as adjusted for any discounts and surcharges.
The per piece charge is computed based on the total number of addressed pieces for each price category claimed. The minimum price may apply to each piece as detailed in 1.1, Standard Mail Price Application. Otherwise, the per piece charge must be added to the per pound charge to determine total postage. Where applicable, the per pound charge is computed based on the total weight of the addressed pieces for each price category claimed, and is added to the per piece charge to determine total postage. For example, a quantity of pieces weighing 100.25 pounds is charged 100.25 times the applicable price per pound, based on the price claimed, plus one unit of the applicable per piece charge for each addressed piece.
To compute postage to be affixed to each piece, multiply the weight of the piece (in pounds) by the applicable price per pound; add the applicable per piece charge and any surcharge; and round the sum up to the next tenth of a cent. The applicable minimum per piece charge must be affixed if it is more than the total computed per piece postage.
1.5.6 Permit Imprint
a. For each price or price category, multiply the number of addressed pieces by the corresponding price per piece and (if applicable) multiply the unrounded total weight of the pieces by the corresponding price per pound; round off each product to four decimal places.
b. Add the per piece and per pound charges and round off the total postage to the nearest whole cent.
2.0 Content Standards for Standard Mail Parcels
Standard Mail consists of mailable matter that is neither mailed or required to be mailed as First-Class Mail nor entered as Periodicals (unless permitted or required by standard) and that weighs less than 16 ounces.
Personal information may not be included in a Standard Mail mailpiece unless all of the following conditions are met:
a. The mailpiece contains explicit advertising for a product or service for sale or lease or an explicit solicitation for a donation.
c. The exclusive reason for inclusion of all of the personal information is to support the advertising or solicitation in the mailpiece.
Mail containing bills or statements of account as defined in 433.2.2 may not be entered as Standard Mail except under the conditions described in 2.5.2.
Mail containing handwritten or typewritten matter may not be entered as Standard Mail except under the conditions described in 2.6.
An invoice, whether it also serves as a bill, may be placed either inside a Standard Mail piece or in an envelope marked “Invoice Enclosed” and attached to the outside of the piece if the invoice relates solely to the matter with which it is mailed. The invoice may show this information:
b. Names and quantities of the articles enclosed, descriptions of each (e.g., price, tax, style, stock number, size, and quality, and, if defective, nature of defects).
c. Order or file number, date of order, date and manner of shipment, shipping weight, postage paid, and initials or name of packer or checker.
Incidental First-Class Mail matter may be enclosed in or attached to Standard Mail merchandise (including books but excluding merchandise samples) without payment of First-Class Mail postage. Incidental First-Class Mail matter may not be enclosed in or attached to matter mailed as Customized MarketMail under 705.1.0. An incidental First-Class Mail attachment or enclosure must be matter that, if mailed separately, would require First-Class Mail postage, is closely associated with but secondary to the host piece, and is prepared not to encumber postal processing. An incidental First-Class Mail attachment or enclosure may be a bill for the product or publication, a statement of account for past products or publications, or a personal message or greeting included with a product, publication, or parcel. Postage at the Standard Mail or Package Services price for the host piece is based on the combined weight of the host piece and the incidental First-Class Mail attachment or enclosure.
Letters or other pieces of nonincidental First-Class Mail, subject to postage at First-Class Mail prices, may be enclosed with Standard Mail pieces (except matter mailed as Customized MarketMail under 705.1.0). Postage for the First-Class Mail enclosure must be placed on the outside of the piece. It may be affixed separately or added to the postage for the host piece. The endorsement “First-Class Mail Enclosed” must be placed on the piece, below the postage and above the address.
Letters or other pieces of nonincidental First-Class Mail may be placed in an envelope and securely attached to the address side of a Standard Mail piece (except matter mailed as Customized MarketMail under 705.1.0), or of the principal piece, as applicable. Combination envelopes or containers with separate parts for the two classes of mail may be used. The names and addresses of the sender and addressee must be placed on both the principal piece and the attachment. Alternatively, the sender’s name and address must be placed on one part and the addressee’s name and address on the other. If the piece is a combination container with inseparable parts or compartments, the names and addresses may appear on only one part. The applicable Standard Mail postage for the Standard Mail matter must be prepaid and placed in the upper right corner of the address space. Postage at the applicable First-Class Mail price must be paid for and affixed to the First-Class Mail attachment, unless other payment methods are permitted by standard.
2.5.5 Attachment of Other Standard Mail Matter
Standard Mail pieces may bear an attachment that is eligible as Standard Mail matter if these additional conditions are met:
a. The piece bearing the attachment is claimed as Customized MarketMail (CMM) under 705.1.0 or as Enhanced Carrier Route Standard Mail under 6.0.
b. The face of the attachment may bear only the price markings and endorsements permitted for the price claimed for the host piece.

f. Each piece in the mailing bears the attachment, and the attachment is of identical size, weight, and positioning on the host piece. Different wording or designs may be used.
g. The attachment does not interfere with processing or delivery. Folded or multipage attachments must be secured to prevent opening during handling.
Markings that have the character of personal correspondence require, with certain exceptions, additional postage at the First-Class Mail prices. The following written additions and enclosures do not require additional First-Class Mail postage:
a. The sender’s and the addressee’s names, occupations, and addresses, preceded by “From” or “To,” and directions for handling.
e. A manuscript dedication or inscription not having the nature of personal correspondence.
h. Manuscripts accompanying related proof sheets and corrections of proof sheets including corrections of typographical and other errors, changes in the text, insertions of new text, marginal instructions to the printer, and corrective rewrites of parts.
i. Handstamped imprints, unless the added material is in itself personal or converts the original matter to a personal communication.
j. Matter mailable separately as Standard Mail printed on the wrapper, envelope, tag, or label.

3.1.2 Minimum Quantity
Standard Mail provides economical prices for mailings of 200 or more pieces or 50 or more pounds of mail.
3.2.1 Mailpiece Weight Limit
3.2.2 Preparation Requirements
3.2.3 Inspection of Contents
3.2.4 Forwarding Service
The price of Standard Mail typically does not include forwarding service. Forwarding service is available under 507.1.5.

3.2.6 Extra Services
Extra services available with Standard Mail are insured mail service (bulk insurance only), certificate of mailing service (bulk certificate of mailing only), return receipt for merchandise service, and Delivery Confirmation service (parcels only). See information regarding extra services in 503.
3.2.8 Identical Pieces
The contents of printed matter in a Standard Mail mailing must be identical to a piece sent to at least one other addressee. Standard Mail may include the addressee's name and address but may not transmit personal information except as permitted under 2.2.
Each Standard Mail mailing is subject to these general standards:
a. All pieces in a mailing must be of the same processing category, except that irregular and machinable parcels may be combined in 5-digit scheme and 5-digit sacks or on 5-digit scheme and 5-digit pallets.
b. Each mailing must contain at least 200 pieces or 50 pounds of pieces. See 3.6, Residual Volume Requirement, for volume requirement eligibility unique to Presorted Standard price mailings. Other volume standards also can apply, based on the price claimed.
c. All pieces in a mailing must be sorted together and marked under the standards for the price claimed.
d. Each piece must bear the addressee’s name and delivery address, including the correct ZIP Code or ZIP+4 code, unless an alternative addressing format is used subject to 602.3.0. Detached address labels may be used subject to 602.4.0.
f. A postage statement, completed and signed by the mailer, using the correct USPS form or an approved facsimile, must be submitted with each mailing. In addition, mailings must be documented under 444.3.0.

h. Mailings must be deposited at a business mail entry unit of the Post Office where the postage permit or license is held and the annual mailing fee paid, unless deposit elsewhere is permitted by standard.
An annual mailing fee must be paid once each 12-month period at each Post Office of mailing. For mail manifested using the Electronic Verification System (eVS) under 705.2.9, only one annual mailing fee, paid at the Post Office of account where the permit imprint account is held, is required regardless of the number of Post Offices of mailing. A mailer paying this fee may enter clients’ mail as well as the mailer’s own. The mailer whose permit imprint appears on pieces in a mailing paid with a permit imprint must show that permit number on the postage statement and must pay the annual mailing fee for that permit; this fee is in addition to the one-time fee for an application to use permit imprints. The fee may be paid in advance only for the next 12 months and only during the last 60 days of the current service period. The fee charged is that which is in effect on the date of payment.
3.5 Merging Similar Standard Mailings
Mailings are subject to the general definitions and conditions in 445.1.0, General Information for Mail Preparation. Generally, mailers may merge similar Standard Mail matter into a single mailing. Differences in text, address labels, and address lists or list key numbers do not prohibit the mailer from merging and sorting pieces together. Pieces with different methods of postage payment may be combined in the same mailing only if authorized by Business Mailer Support (BMS). Pieces of nonidentical weight, if merged in the same mailing, must bear the correct postage when mailed, unless otherwise authorized by BMS.
Pieces in an Enhanced Carrier Route price mailing that has separately met a 200-piece or 50-pound minimum quantity requirement may be counted toward the minimum quantity requirement for a Presorted price mailing, provided that the Enhanced Carrier Route price mailing and the Presorted price mailing are part of the same mailing job. Likewise, pieces in an automation price mailing that has separately met a 200-piece or 50-pound minimum quantity requirement may be counted toward the minimum quantity requirement for a Presorted price mailing, provided that the automation price mailing and the Presorted mailing are part of the same mailing job. Pieces mailed at Presorted Standard Mail prices must not be counted toward the minimum volume requirements for an Enhanced Carrier Route price or an automation price mailing.
3.7 Residual Mail Subject to First-Class Mail or Priority Mail Prices
Pieces prepared as Standard Mail (i.e., that bear Standard Mail price markings, ACS codes, etc.) that do not qualify for Enhanced Carrier Route, automation, or Presorted Standard Mail prices are subject to the single-piece First-Class Mail or Priority Mail prices as applicable for the weight of the mailpiece. Metered pieces weighing over 13 ounces but less than 16 ounces that do not qualify for Standard Mail prices and any pieces that do not qualify for Standard Mail prices for which First-Class Mail or Priority Mail service is desired must be re-enveloped or otherwise prepared so that they do not bear Standard Mail markings, endorsements, and ACS codes and must bear the proper First-Class Mail or Priority Mail price markings and ACS codes. Mailers who have pieces (other than metered pieces weighing over 13 ounces but less than 16 ounces) that do not qualify for Standard Mail prices but that are prepared as Standard Mail and who do not desire to receive First-Class Mail or Priority Mail service for those pieces may enter their mailpieces “as is” (i.e., bearing the Standard Mail markings and endorsements), provided the requirements in 444.1.0, Basic Standards for Postage Payment, are met.
3.8.1 Basic Standards
The ZIP Code accuracy standard is a means of ensuring that the 5-digit ZIP Code in the delivery address correctly matches the delivery address information. For the purposes of this standard, address means a specific address associated with a specific 5-digit ZIP Code. Addresses used on pieces claiming certain prices under 3.8.1d., Basic Standards that are subject to the ZIP Code accuracy standard must meet these requirements:
a. Each address and associated 5-digit ZIP Code used on the mailpieces in a mailing must be verified and corrected within 12 months before the mailing date with one of the USPS-approved methods in 3.8.2.
c. If an address used on a mailpiece in a mailing at one class of mail and price is verified and corrected with an approved method, the same address may be used during the following 12 months to meet the ZIP Code accuracy standard required for mailing at any other class of mail and price.
d. Except for mail bearing a simplified address, addresses used on pieces claiming the Standard Mail prices must meet the ZIP Code accuracy standard, regardless of any required surcharges.
3.8.2 USPS-Approved Methods
a. For computerized lists, Coding Accuracy Support System (CASS)-certified address matching software and current USPS City State Product, within a mailer’s computer systems or through an authorized service provider.
1. Surveys of addressees on mailer’s address list inquiring about the accuracy of ZIP Code information.
3.8.3 Mailer Certification
The mailer’s signature on the postage statement certifies that the ZIP Code accuracy standard has been met for each address in the corresponding mailing presented to the USPS.
3.9.1 Basic Standards
The Move Update standard is a means of reducing the number of mailpieces in a mailing that require forwarding, return, or discard by the periodic matching of a mailer's address records with customer-filed change-of-address orders received and maintained by the USPS. For the purposes of this standard, address means a specific address associated with a specific occupant name. Except for mail bearing an alternative address format, addresses used on pieces claiming Standard Mail prices must meet the Move Update standard. Addresses subject to the Move Update standard must meet these requirements:
a. Each address and associated occupant name used on the mailpieces in a mailing must be updated within 95 days before the mailing date, with one of the USPS-approved methods in 3.9.2.
c. The Move Update standard is met when an address used on a mailpiece in a mailing at any class of mail is updated with an approved method in 3.9.2, and the same address is used in a Standard Mail mailing within 95 days after the address has been updated.
3.9.2 USPS-Approved Methods
3.9.3 Mailer Certification
The mailer's signature on the postage statement certifies that the Move Update standard has been met for each address in the corresponding mailing presented to the USPS.
Mailings are subject to a Move Update assessment charge if more than 30 percent of addresses with a change of address (COA) are not updated, based on the error rate found in USPS sampling at acceptance during Performance-Based Verification. Specifically, mailings for which the sample contains greater than 30 percent failed COAs out of the total COAs are subject to additional postage charges as follows:
a. The percentage of the mailing paying the charge is based on the percentage of failed pieces above 30 percent.
c. As an example, if 40% of COAs in the sample are not updated, then the charge is applied to 10% (=40% - 30%) of the total mailing.
d. Mailings for which the sample has five or fewer pieces that were not updated for a COA are not subject to the assessment, regardless of the failure percentage.
4.0 Price Eligibility for Standard Mail
