The Move Update standard is a means of reducing the number of mailpieces in a commercial mailing that require forwarding, returning, or treating as waste by periodically matching a mailer's address records with change-of-address orders maintained by the Postal Service. The revised Guide to Move Update is now posted on RIBBS®. Revisions include new subsections "Overview of the Change of Address Process"; "What is a PAF and Why is It Required?"; "Non-US Mailers and NCOALink"; and "NCOALink MPE." The Quick Start Guide at the beginning of the Guide to Move Update has been reworked to emulate the DMM Quick Service Guide and the Move Update Questions and Answers section has been revised and clarified. The complete Guide to Move Update can be found on RIBBS at https://ribbs.usps.gov/index.cfm?page=moveupdate under Important Links.
