Quick Summary

Certified mail is a service offered by postal services that provides proof of delivery for first-class mail. This means that the sender receives confirmation that the mail has reached its destination, but it does not include any insurance or indemnity value for the contents. It is distinct from registered mail, which is recorded at each step of its transmission and guaranteed special care. A certificate of mailing is also available for a small fee, attesting to the nature, destination, and mailing date of a piece of mail. Certified mail was first used in 1947.1234
