DMM Revision: Amended Move Update Standards

Effective November 23, 2008, the Postal Service™ revised the Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®) 233.3.5, 243.3.9, 333.3.5, 343.3.9, 433.3.5, and 443.3.9 to reflect the changes to the Move Update standard.

The Move Update standard is a means of reducing the number of mailpieces in a mailing that require forwarding, return, or discard by the periodic matching of a mailer’s address records with customer-filed change-of-address orders received and maintained by USPS®.

The DMM is updated to include the revisions that signify mailing addresses must be updated within 95 days prior to the mailing date, and that this revision includes Standard Mail® service in addition to First-Class Mail® service.

We will incorporate this revision into the next printed version of the DMM and into the next update of the online DMM available via Postal Explorer® at
