Description

The Move Update standard is a means of reducing the number of mailpieces requiring forwarding or return by periodically matching the mailer's address records with change-of-address (COA) orders received and maintained by the Postal Service™. Mailers who claim presorted or automation prices for First-Class Mail® or Standard Mail® service must demonstrate that they have updated their mailing list within 95 days before the mailing date.

The Postal Service offers three preapproved methods: ACS™, NCOALink®, NCOALink MPE, and Ancillary Service Endorsements except for Forwarding Service Requested.

Alternative methods: 99 Percent Accurate and Legal Restraint 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.
