A requirement for presorted and automation First-Class Mail service and for all Standard Mail service that helps reduce the number of mailpieces in a mailing that might require forwarding or return because of outdated or inaccurate addresses. The mailer periodically matches address records with customer-filed change-of-address orders received and maintained by USPS. By performing these address matches, mailers can avoid mailing to customers at old addresses. Approved methods of meeting this requirement include Address Change Service, National Change of Address Linkage System, FASTforward service, and Ancillary Service endorsements except Forwarding Service Requested.
