Requirements for USPS Return Address Endorsements

Designing and setting up the mail panel properly for a direct mail piece is very important and it can determine how much you pay in postage. Following a few guidelines can save you big bucks at the Post Office! Here are some quick tips regarding the  requirements for USPS return address endorsements:

Physical Standards (102.4.0)

An endorsement must be printed in no smaller than 8-point type, and it must stand out clearly against its background. Brilliant-colored envelopes and reverse printing are not permitted. There must be a 1/4-inch clear space around all sides of the endorsement. The endorsement and return address must read in the same direction as the delivery address.

Placement of Endorsement (202.4.0)

The exhibit below shows the options for placing an endorsement. The endorsement shown (ADDRESS SERVICE REQUESTED) is just one of several options. See DMM 507.1.5 for a complete list of endorsements, treatment, and fee consequences according to the class of mail.
