1.18 Computing Postage for First-Class Mail

Determine single-piece weight and weight (postage) increment for each addressed piece as prescribed in 1.19 and 1.2, Rate Computation for First-Class Mail Letters. For First-Class Mail, affix postage to each piece under 234.2.2, Affixed Postage for Presorted First-Class Mail, or, for permit imprint mailings, multiply the number of addressed pieces at each rate increment (and in each rate category, if applicable) by the corresponding postage rate, add the unrounded products, and round off the total postage to the nearest whole cent.

1.19 Determining Single-Piece Weight

To determine single-piece weight in any mailing of nonidentical-weight pieces, weigh each piece individually. 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. Express all single-piece weights in decimal pounds rounded off to four decimal places.

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 Move Update Standard

3.5.1 Basic Standards

The Move Update standard is a means of reducing the number of mailpieces in a mailing that require forwarding or return 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. 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 185 days before the mailing date, with one of the USPS-approved methods in 3.5.2.

b. Each individual address in the mailing is subject to the Move Update standard.

c. If an address used on a mailpiece in a mailing at one class of mail and rate is updated with an approved method (e.g., Address Change Service), the same address may be used during the following 185 days and meets the Move Update standard.

d. Except for mail bearing an alternative address format, addresses used on pieces claiming First-Class Mail Presorted rates, regardless of any required surcharge, must meet the Move Update standard.

3.5.2 USPS-Approved Methods

The following methods are authorized for meeting the Move Update standard:

a. Address Change Service (ACS).

b. National Change of Address Linkage System (NCOALink).

c. FASTforward MLOCR processes if used each time before mail entry. If a mailpiece that initially uses FASTforward MLOCR processing is rejected and then entered into a Direct View Encoding Desk (DVED) operation (or similar system), the piece does not meet the Move Update standard. The name and address information on the piece must then be processed through a FASTforward RVE system to meet the Move Update standard. FASTforward RVE processes also meet the Move Update standard if used each time before mail entry.

d. Mailer Move Update Process Certification and USPS-approved alternative methods for mailers with legitimate restrictions on incorporating USPS-supplied change-of-address information into their mailing lists. The National Customer Support Center (see 608.8.1 for address) administers and approves both Mailer Move Update Process Certification and alternative methods.

e. Ancillary service endorsements under 507.1.5.1, First-Class Mail and Priority Mail, except "Forwarding Service Requested."

3.5.3 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.

3.6 ZIP Code Accuracy

3.6.1 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 rates under 3.6.1d 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 3.6.2.

b. Each individual address in the mailing is subject to the ZIP Code accuracy standard.

c. If an address used on a mailpiece in a mailing at one class of mail and rate 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 rate.

d. Except for mail bearing a simplified address, addresses used on pieces claiming First-Class Mail rates, regardless of any required surcharges, must meet the ZIP Code accuracy standard.

3.6.2 USPS-Approved Methods

The following methods are authorized for meeting the ZIP Code accuracy standard:

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.

b. For manually maintained lists or small computerized lists, options include the following:

1. Surveys of addressees on mailer's address list inquiring about the accuracy of ZIP Code information.

2. Any mailing list service in 507.6.0.

3. An authorized service provider.

4. CASS-certified matching software.

5. USPS Web site www.usps.com.

A numeric ZIP+4 code must consist of five digits, a hyphen, and four digits.

5.6.3 Numeric Delivery Point Barcode (DPBC)

A numeric equivalent of the delivery point barcode (DPBC) consists of five digits followed by a hyphen and seven digits as specified in 202.5.6. The numeric equivalent is formed by adding three digits directly after the ZIP+4 code.

Addresses must include the correct street number, predirectional, street name, suffix, and postdirectional that are input to obtain a match with the current USPS ZIP+4 Product.

5.6.5 Firm Name

An address must include a firm name when necessary to obtain a match with the finest level of ZIP+4 code in the USPS ZIP+4 Product. If an address contains a firm name assigned a unique ZIP+4 code in the USPS ZIP+4 Product, the unique ZIP+4 code must be used. If the firm name is not one assigned a unique ZIP+4 code in the USPS ZIP+4 Product and the apartment/suite number is included in the address, the ZIP+4 code for the range in which the apartment/suite number appears must be used in that address. If the firm name does not correspond to a firm name that has a unique ZIP+4 code assigned in the USPS ZIP+4 Product and the apartment/suite number is not included in the address, the ZIP+4 code for the building must be used.

5.6.6 Secondary Designator

If a secondary address designator (e.g., an apartment number) is shown in the address, the mailpiece must show the appropriate ZIP+4 code representing the range for that secondary address as contained in the current USPS ZIP+4 Product. If a secondary address designator is required to obtain an exact match with the finest level of ZIP+4 code in the USPS ZIP+4 Product but the information is not available, the alternative ZIP+4 code or ZIP+4 or delivery point barcode for the building must be used.

5.6.7 Rural and Highway Contract Routes

If a rural route or highway contract route box number is included in the address, the mailpiece must show the appropriate ZIP+4 code representing the range for that box number as contained in the current USPS ZIP+4 Product. If a rural route or highway contract route box number is required to obtain a match with the finest level of ZIP+4 code but is not available, the alternative ZIP+4 code or ZIP+4 or delivery point barcode for the rural route or highway contract route must be used. If used, the rural route or highway contract route box number must be placed on the line immediately above the city/state/ZIP Code line.

5.6.8 P.O. Box

A post office box address must contain a post office box number that can be exactly matched with the USPS ZIP+4 Product in effect.
