November DMM^® Update

Postal Explorer^® (pe.usps.com) is your source for up-to-date mailing standards. The Domestic Mail Manual (DMM^®) is fully searchable on Postal Explorer and features fly-out menus, cross-reference links, and an extensive subject index. Today, we updated our mailing standards to include the following changes:

Periodicals - Record of Deposit

We revised 207.5.2.2 to clarify the mailing standards for pending Periodicals applications. Specifically, this revision will add preparation and payment guidelines for a publication while mailing as a pending Periodical. We published this information in the October 12, 2017, Postal Bulletin.

Barcode Standards

We revised 204.2.0, Standards for Package and Extra Service Barcodes, to update barcode standards. We published this information in the September 28, 2017, Postal Bulletin.

Ride-along Eligibility

We revised the 207.15.2 by adding clarification guidelines for a Periodicals mailing with a USPS Marketing Mail ride-along. We published this information in the September 28, 2017, Postal Bulletin.

Our next scheduled DMM update is January 21, 2018.
