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:


District Consolidations—ZIP Code Realignments

We revised 608.8.4  to align various 3-Digit ZIP Code™ service areas with the appropriate Manager Business Mail Entry District listing. We published this information in the March 8, 2012, Postal Bulletin.  


Increase eBay Insurance Indemnity Limit

We revised 503.1.0 to align the maximum indemnity for all sources of domestic postal insurance to the same $5000 limit. We published this information in the March 8, 2012, Postal Bulletin.


Optional Preparation for FSS Zones When Combining Mailings of Standard Mail and Periodicals Flats

We revised 705.15.0 to provide an option for mailers authorized to combine mailings of Standard Mail® and Periodicals flats to also prepare these mailings in accordance with the FSS preparation standards under 705.14.0, and we revised 708.7.1 to describe the new optional endorsement line (OEL) standards when these two mailing options are used together. We published this information in the February 23, 2012, Postal Bulletin.


Shipper Paid Forwarding—Treatment of Mail

We revised 507.1.0 to clarify the treatment of mail for Shipper Paid Forwarding service. We published this information in the February 23, 2012, Postal Bulletin.


Our next scheduled DMM update is May 7.
