Choose certified mail when you need proof of delivery and time is of the essence. Registered mail is the Postal Service's most secure form of mail delivery, involving an unbroken chain of custody. Registered mail is protected in sealed containers, safes and cages, and held under lock and key.
Certified Mail is a type of Special Service mail offered by the United States Postal Service and other postal services that allows the sender proof of mailing. Some in-transit tracking and delivery confirmation information may be provided, but is not guaranteed with Certified Mail. Certified Mail is only available for Priority Mail and First Class Mail letters mailed within the United States and its territories.
