LetterStream Return Address Requirements

Using our website requires 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, has a deceptive return address, or an international 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.
