Ancillary Service Endorsements

Description

Undeliverable-as-addressed (UAA) mail is forwarded, returned to the sender, or treated as dead mail, as authorized for the particular mail class. A mailer endorsement is used to request forwarding, return, change, or address correction service. These are identified as "Ancillary Service Endorsements."

Four ancillary service endorsements are used for all mail classes:

  • Address Service Requested
  • Forwarding Service Requested
  • Return Service Requested
  • Change Service Requested

Please refer to the chart below for information on endorsements for First-Class Mail, Priority Mail, and Express Mail.

Expected Benefits

Ancillary service endorsements allow the sender to obtain on request (provided the appropriate ancillary service endorsement is used) the addressee’s new (forwarding) address (if the addressee filed a change-of-address order with the Postal Service) or the reason for non-delivery. These endorsements also provide the Postal Service with instructions for the disposition of UAA mail. These endorsements provide a simpler and more consistent system than the one currently in place.
