Ancillary Service Endorsements (ACS)

ACS™ is a USPS® change of address service available to help you either attain new address information, or the reason for non-delivery on mail that has already entered the USPS mailstream. Information is returned in an electronic file, making updates more efficient and accurate than manual updates.
