Definition and Meaning of the Certificate of Mailing

The Certificate of Mailing offers a straightforward way to provide proof that a piece of mail has been handed over to the United States Postal Service (USPS) for delivery. Unlike other mailing services, this certificate does not confirm delivery or guarantee a delivery date. Instead, it serves as evidence that the mail was sent, which can be crucial in business or legal contexts where proof of dispatch is necessary.

  • Purpose: Primarily used for business or legal purposes to ensure there is documented proof of mail handling.
  • Not a Proof of Delivery: It should be noted that the Certificate of Mailing is not a substitute for delivery confirmation services.

  3. Affix Proper Postage: Pay for the mail item by affixing the necessary stamps or having postage metered at the post office.
