Certified Mail is a special service from the USPS that provides the sender with a mailing receipt and electronic verification. The sender is notified about the sent package/mail that it was delivered or that a delivery attempt was made.
The delivery status of the package/mail can be retrieved in three ways:
- From the official USPS Website – https://www.usps.com/ by entering the Tracking Number as found on the mailing receipt.
- By calling the customer service and finding out the status through USPS Tracking number
- By bulk electronic file transfer for mailers who provide an electronic manifest to the USPS
