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 service provided by the United States Postal Service in which the sender of an envelope or package receives a proof of delivery postcard after the item has been delivered, signed by the recipient. The postcard includes the date and time. The sender then knows the item has been received by the addressee.
