DMM Revision: Guaranteed by End of Day Endorsement for Express Mail Service

Effective November 6, 2008, the Postal Service™ is revising the Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®) 413.4.2.1 and 413.4.3.1 to include the option for Express Mail Corporate Account (EMCA) customers to endorse their domestic Express Mail® items with “Guaranteed by End of Day” when they have an approved customer agreement that allows them to do so.

Currently, Express Mail items must be delivered by a specific time, either noon or 3 p.m. With an approved cus­tomer agreement, EMCA customers are allowed to endorse their Express Mail items with Guaranteed by End of Day. This endorsement does not provide a time-certain delivery guarantee, but provides for delivery by the end of the day on a specific date. “End of Day” is the time that a Postal Service letter carrier actually completes the delivery route covering the recipient’s address in the normal line of travel. This endorsement makes it possible for Express Mail items to be delivered by the regular carrier at the time of the customer’s regular delivery for the address, without the need for a special Express Mail delivery trip or deviation from the letter carrier’s route.

We will incorporate these revisions into the November update of the online DMM on Postal Explorer® at http://pe.usps.com and into the next printed edition of the DMM.
