:: Importance of Return Address

The Postal Service encourages all mailers to use return addresses so that undeliverable mail can be returned to the customer. This allows you to update your list for future mailings.

A return address tells the USPS where the sender wants the mail returned if it is undeliverable.

A return address is required on certain types of mail. Mail qualifying for Nonprofit Standard Mail rates must have the name and return address of the authorized nonprofit organization either on the outside of the mail piece or in a prominent location on the material being mailed.
