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.

First Class Mail

Stay Compliant with Move Update

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® and USPS Marketing Mail prices 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®, and ancillary service endorsements except for Forwarding Service Requested.

Alternative methods: 99 Percent Accurate and Legal Restraint that require separate approval are also offered for First-Class Mail. Mailers must use one of the preapproved or alternative methods to meet the Move Update standard.
