Return Address Requirements
You don't need a return address on your envelope if you send a letter through the USPS directly. However, if you use our website, we do require that a valid USA return address is included on your mailings. We need this in order to comply with specific USPS rules due to the way we submit mail to them.
If your letter doesn't have a return address or has a deceptive return address, we may need to hold up your mail. To see other items that may violate our user agreement, please review the details on our shopping cart/check out page.
