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.
What does the Post Office do with dead mail?
Known at one time as the Dead Letter Office, the Mail Recovery Center works to reunite undeliverable packages and letters with either sender or recipient. Processing centers and retail and delivery units send mail items without valid addressee and sender information to the MRC, where MRC staff act as detectives.

What happens to mail with wrong address?
According to the USPS, mail can be considered “undeliverable” due to a number of factors ranging from insufficient postage to the person it’s addressed to refusing to accept it. Regardless of the reason the mail cannot be delivered, the USPS states that: “All nonmailable pieces are returned to the sender.”
