April 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 April 1 we updated our mailing standards to include the following changes:


5-Digit/Scheme and 3-Digit/Scheme Sortation

We revised 235 and 245 to clarify the preparation of 5-digit/scheme and 3-digit/scheme trays. This notice similarly revises DMM 345, 365, and 375 regarding 5-digit/scheme sacking of Standard Mail, Bound Printed Matter, Media Mail, and Library Mail flats. We published this information in the March 7, 2013, Postal Bulletin.


Clarification of Standards Relating to IMpb Use

We revised 708.5.1.1 to clarify standards relating to the data requirements of the electronic file that mailers submit along with mailings bearing Intelligent Mail package barcodes (IMpb). We published this information in the March 7, 2013, Postal Bulletin.


New Price Eligibility for 5-Digit Containers Deposited at FSS Facilities

We revised 346.4.0, 366.5.0 and 707.29.0 to provide Destination Sectional Center Facility (DSCF) eligibility for 5-digit containers of bundles of addressed machinable Periodicals, Standard Mail or Bound Printed Matter flats deposited at Flats Sequencing System (FSS) processing facilities. We published this information in the March 7, 2013, Postal Bulletin.


Promotions and Incentive Programs for First-Class Mail and Standard Mail

We revised 709.3 to include new promotions and incentive programs that will be offered at various time periods during calendar year 2013 for Presorted and automation First-Class Mail cards, letters, and flats, and Standard Mail letters, flats, or parcels. We published this information in the March 7, 2013, Postal Bulletin.


Our next scheduled DMM update is May 6, 2013.
