Address Service Requested: The mailpiece is forwarded to the new location when possible and a printed notice is returned to the mailer with the new address information. This notice is then used by the mailer to update the address list.
Months 1-12: the mailpiece is forwarded at no charge; the mailer is provided a separate notice of new address and charged an address correction fee (fee is determined by the USPS).
Months 13-18: for First-Class Mail, the mailpiece is returned with the new address attached at no charge. For Standard Mail, the mailpiece is returned at a weighted fee.
After month 18 or if undeliverable at any time: the mailpiece is returned with reason for nondelivery. Fee charged for Standard Mail
Use of an ancillary endorsement on a mailpiece obligates you to pay USPS any applicable charges for forwarding, return, and separate address notification charges. Details can be found here: USPS
Important: per USPS Move Update requirements, your use of ancillary endorsements obligates you to update address records with all changes that you receive back from USPS.
