Guide to 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 First-Class Mail presorted or automation prices and USPS Marketing Mail prices must demonstrate that they have updated their mailing list within 95 days before the mailing date.
