What Does The Post Office Do With Undeliverable Mail?

A dead letter office (DLO) is a facility within a postal system where undeliverable mail is processed.

Mail is considered to be undeliverable when the address is invalid so it cannot be delivered to addressee, and there is no return address so it cannot be returned to the sender.

How long does post office hold undeliverable mail?

After the unsuccessful delivery, the letter carrier brings the mail item back to the post office, and the post offices hold mail for 15 days before returning it to the sender. If someone comes to claim for the mail item within 15 days, then it’s okay, and if no one comes, then that mail item will be returned to sender.
