Certified Mail®

Certified Mail is an extra service that provides the sender with a mailing receipt, tracking history, and, upon request, electronic verification that a mail piece was delivered or that a delivery attempt was made. Certified Mail can be used with both First-Class and Priority Mail, and items sent with this extra service are dispatched and handled in transit as ordinary mail.  This guide provides an explanation of the product, the different types of Certified Mailings, and instructions for preparing Certified Mail.
