Description

What are Ancillary Service Endorsements?

Ancillary Service Endorsements allow the sender to obtain the addressee's new (forwarding) address (provided the appropriate endorsement is used and if the addressee filed a Change-of-Address Order with the Postal Service) or the reason for non-delivery.

Undeliverable-as-addressed (UAA) mail is forwarded, returned to sender, or discarded as authorized for the particular mail class. A mailer endorsement is used to instruct the Postal Service regarding the appropriate disposition upon determining that it is UAA. A return address is required on the face of the mailpiece when using ancillary service endorsements. The following endorsements may be used as an updating method to meet the move update standards for First-Class™ and Standard Mail®.

Change Service Requested

Separate notice of new address or reason for non-delivery provided; in either case, address-correction fee is charged; mailpiece is not forwarded or returned, but discarded by the Postal Service. 

Address Service Requested 

Mail is forwarded if possible, or returned if forwarding is not possible. A separate notice with new address information is provided for forwarded pieces and the address-correction fee is charged. First-Class Mail is forwarded or returned at no charge. Standard Mail is charged the weighted fee for mail that must be returned. The Weighted Fee is equal to the single-piece First-Class price multiplied by 2.472 (a one ounce letter is charged 50¢ x 2.472 = $1.236, rounded-up to $1.24)

  • Months 1 - 12: the mailpiece is forwarded; no charge; a separate notice of the new address is provided.
  • Months 13 - 18: the mailpiece is returned with the new address attached.
  • After month 18 or if undeliverable: the mailpiece is returned with reason for non-delivery attached.

Return Service Requested

If UAA, the mailpiece is returned with the new address or reason for non-delivery. First-Class Mail is returned at no charge. Standard Mail is returned at the appropriate single-piece First-Class price.

Temp-Return Service Requested

This endorsement option is available for First-Class Mail only. If UAA and a temporary change-of-address have been filed, the mailpiece is forwarded at no charge. No separate notice of a new temporary change-of-address is provided.

Ancillary Service Endorsement Authorized Locations

Ancillary service endorsements may be placed under the return address, above the delivery address block, to the left of the postage area, or below the postage area (postage stamps, meter stamps, or permit imprints).
