ancillary service endorsements

Ancillary service endorsements are used by mailers to request an addressee's new address and to provide the USPS with instructions on how to handle undeliverable-as-addressed mail pieces. The endorsements are the same for all classes of mail, but the treatment and cost differ by class of mail. Use of an ancillary service endorsement on a mail piece obligates the mailer to pay any applicable charges for forwarding, return, and separate address notification charges.

Proper placement of the endorsement is required. If the endorsement cannot be seen or understood you might might not receive the service requested.

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.
