Ancillary Service Endorsements
Undeliverable-as-addressed (UAA) mail is forwarded, returned to sender, or treated as dead mail depending upon authorization for the particular mail class. An ancillary service endorsement is used to instruct the Postal Service regarding the mailpiece’s appropriate disposition upon determining that it is UAA. On First-Class Mail, the following endorsements may be used as an updating method to meet the move update standard:
Return Service Requested. If UAA, the mailpiece is returned with the new address or reason for nondelivery; no charge.
Address Service Requested.
Months 1 - 12: the mailpiece is forwarded; no charge; a separate notice of the new address is provided; an address correction fee is charged.
Months 13 - 18: the mailpiece is returned with the new address attached; no charge.
After month 18 or if undeliverable: the mailpiece is returned with reason for nondelivery attached; no charge.
Change Service Requested. Separate notice of new address or reason for nondelivery provided; in either case, address-correction fee is charged; mailpiece is not forwarded or returned but disposed of by the Postal Service. This endorsement option is available for First-Class Mail only when used in conjunction with electronic Address Change Service (ACS).
Ancillary service endorsements allow the sender to obtain or request (provided the appropriate 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 nondelivery. These endorsements also provide the Postal Service with instructions regarding the disposition of UAA mail. These new endorsements provide a simpler and more consistant system than the previous endorsements.
