March DMM Update


Postal Explorer ( 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. On March 4 we updated our mailing standards to include the following changes:


Usage of Franked Envelopes and Labels

We revised 703.6.2.1 to clarify the use of franked envelopes and labels. We published this information in the February 21, 2013, Postal Bulletin.


USPS Tracking/Delivery Confirmation Label Usage

We revised 503.11.0 to clarify the use and application of integrated retail systems labels and other unique, USPS-provided tracking labels for USPS Tracking/Delivery Confirmation service. We published this information in the February 21, 2013, Postal Bulletin.


Intelligent Mail Barcode on Periodicals, Flats and Letters

We revised 707.12.0, 13.0 and 14.0 to correct the omission of standards limiting automation discounts for Periodicals letters and flats to Intelligent Mail barcodes only. We published this information in the February 7, 2013, Postal Bulletin.


New Minimum Value for Treatment as Dead Mail

We revised 507.1.9 to update the minimum value for treating undeliverable articles as dead mail. We published this information in the January 10, 2013, Postal Bulletin.


Our next scheduled DMM update is April 1, 2013.
