Move Update

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 change-of-address orders received and maintained by the Postal Service. Mailers who claim presorted or automation prices for First-Class Mail or Standard Mail must demonstrate that they have updated their mailing list within 95 days before the mailing date.

Who is Move Update for?

Mailers who claim presorted or automation prices for First-Class Mail or Standard Mail.

First Class Mail
Standard Mail


The Postal Service offers three preapproved methods: Address Change Service (ACS), National Change of Address Linkage System (NCOALink), and ancillary service endorsements except for Forwarding Service Requested. Alternative methods that require separate approval also are offered for First-Class Mail. Mailers must use one of the preapproved or alternative methods to meet the Move Update standard.

The Move Update standard is met when an address used on a mailpiece in a mailing for any class of mail is updated with an approved method and the same address is used in a commercial First-Class Mail or Standard Mail mailing within 95 days after the address has been updated. Except for mail bearing an alternative address format, addresses used on all pieces claiming Standard Mail prices are required to meet the Move Update standard.

ACS is a post mailing service that allows mailers to receive change-of-address (COA) and other reasons for non-delivery electronically and reduce the number of manual (hardcopy) address notifications.


The NCOALink Product is a secure dataset of approximately 160 million permanent change-of-address (COA) records consisting of names and addresses of individuals, families and businesses who have filed a change of address with the Postal Service™. Developed with secure data store technology to increase security of postal customer data and protect the privacy of this information, the NCOALink Product enables mailers to process mailing lists and update lists with new addresses prior to mailing. The NCOALink data is provided on a regular basis to companies that have been licensed by the Postal Service.

Ancillary Service Endorsements

Ancillary Service Endorsements allow for a sender to obtain an addressee’s forwarding/new address if the addressee has filed a Change-of-Address order with the Postal Service, or a reason for why a mailpiece has not been delivered.

99% Testing

The 99% Accurate test is a computer-based process that performs Postal Service ZIP + 4® coding and change-of-address processing utilizing the customer’s file as input. The 99% Accurate test is accomplished by submitting the mailer’s address file(s) to the Postal Service for processing.
