What Is a Return Address?

A return address (also known as the sender's address) is used by the USPS to return undeliverable mail. Including a return address ensures:

  • Failed deliveries are returned to you
  • USPS can process your mail correctly
  • Your mailing complies with USPS regulations

Default Return Address

Before submitting your first mailing through LetterStream, you’ll be prompted to add a default return address. This is required because:

  • Every piece of mail must include a valid U.S.-based return address
  • Missing or invalid return addresses may cause delivery delays or USPS rejection

You can override the default return address for individual jobs if needed.

Using a Return Address Logo

You have the option to add a logo or image in place of your return address:

  • Black and White Printing: Free of charge
  • Color Printing: $0.15 per recipient

Ensure that your image includes the actual return address within the artwork. For step-by-step instructions, click here.

International Return Addresses

Currently, LetterStream does not support international return addresses. Here's why:

  • Mailings are paid for using domestic U.S. postage
  • If the USPS cannot deliver the letter, it must return it to a U.S.-based location
  • International returns require additional postage not covered in the original mailing
