Ancillary Service Endorsements

Each class of mail is handled a certain way when it is undeliverable, either due to the recipient having a forwarding address or not being known at the delivery address.  Ancillary service endorsements allow you to request alternate handling for undeliverable mail.  For example, instead of being forwarded, you cab request the mail piece be returned to you with the forwarding address.

The endorsement wording must be exact, be in at least 8 point type, have at least 0.25 inch clear space around it and be located in one of these four locations:

  • Directly below the return address
  • Directly above the delivery address
  • Directly to the left of the postage area
  • Directly below the postage area

The different endorsements and how the Postal Service will handle the mail are explained below. When a separate notice of the new address or the reason for nondelivery is sent back to sender, they are sent back postage due at 75¢ each.
