May 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. Yesterday, we updated our mailing standards to include the following changes:

Change in Dimensions for Standard Mail Saturation Flats with Simplified Addresses

We revised 301 and 602 to change the size of pieces allowed as Standard Mail saturation flats when those pieces bear simplified addresses. We published this information in the April 19, 2012, Postal Bulletin.

New Content Identification Number Codes for Use with Priority Mail Open and Distribute Shipments

We revised 705.18.0 and Exhibit 708.6.2.4 to provide an expanded choice of content identification number (CIN) codes for use with Priority Mail Open and Distribute (PMOD) shipments. We published this information in the March 22, 2012, Postal Bulletin.

Our next scheduled DMM update is June 24, 2012.
