There are several reasons why mail can be undeliverable, such as an incorrect address, an expired forwarding order, or the recipient refusing the mail.
Undeliverable USPS mail is returned to the sender if there is a return address on the mailpiece. If there is no return address or other way to identify the sender, mail is delivered to the USPS Mail Recovery Center (MRC) in Atlanta, Georgia.
At the MRC, the mail is processed and sorted in an attempt to identify the sender or recipient. The USPS then attempts to return the mail to the sender or forward it to the correct address if possible. If the mail cannot be returned or forwarded, it may be auctioned off or destroyed.
It is important to ensure that mail is addressed correctly and that any forwarding orders are up to date to avoid mail being undeliverable.
