“Address service requested” means that a piece of U.S. mail is sent to the new address for free, and the sender is charged for a separate notice of the new address. This can happen for up to a year if the Postal Service has your new address on file.
13 to 18 months after a person moves, mail marked “address service requested” is sent back to the sender with the new address attached. After 18 months, the piece is sent back with a note explaining why it wasn’t sent. This service is one of the extra ones that the U.S. Postal Service offers to people who send mail. Costs vary based on what kind of mail is being sent, such as first-class letters, priority mail, or magazines.
