How to send mail back to sender usps

To send mail back to the sender using the United States Postal Service (USPS), you can follow these steps:

Return to Sender: If the mailpiece has a "Return to Sender" label or a notation on the envelope, you can simply place the mailpiece in a USPS mailbox or take it to a post office.
Undeliverable As Addressed (UAA): If the mailpiece is undeliverable due to an incorrect or incomplete address, you can take it to a post office and ask the postal clerk to mark it as "Undeliverable As Addressed" (UAA). The USPS will then return the mailpiece to the sender.
Return Receipt Requested: If you want to confirm that the mailpiece was returned to the sender, you can request a return receipt. To do this, you'll need to attach a return receipt request (RRR) label to the mailpiece. The sender will then receive a confirmation when the mailpiece is returned.
Postage: Make sure to affix the correct postage to the mailpiece before sending it back to the sender.

Tips:

If the mailpiece is damaged or has no return address, you may need to contact the sender directly to request their return address.
If you're unable to determine the sender's return address, you can contact the USPS Customer Service department for assistance.
Keep in mind that the USPS may not be able to return mailpieces that are undeliverable due to a non-existent or incorrect sender address.
