Ancillary Service Endorsements

Ancillary service endorsements are used to request an addressee's new address and to provide the postal service with instructions on how to handle undeliverable-as-addressed pieces.  The endorsements are the same for all classes of mail, but the treatment and cost differ by the class of mail.
