DMM Advisory

May 17, 2005


Following are the May 2005 changes to the Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM 300).


Mailers who prepare merged pallets of AFSM 100-compatible, flat-size Periodicals, Standard Mail, and Bound Printed Matter mailpieces must prepare 3-digit scheme bundles.

Mailers who enter pallets at BMC/ASF, ADC, and SCF facilities now have the option to prepare specific pallets weighing a minimum of 100 pounds.

Labeling Lists

Effective May 15, 2005, mailers no longer may use labeling list L004 for Optional Endorsement Line (OEL) and sack labeling for mixed ADC bundles and sacks of nonautomation rate flats.  Mailers must use L009 for OEL and sack labeling for mixed ADC bundles and sacks of nonautomation rate flats and for some irregular parcels.
