Certified Mail vs. Registered Mail

Certified Mail vs. Registered Mail Certified Mail provides you with a receipt at the time of mailing and a record of delivery. Certified is a good choice when you want to prove that you mailed something and that it was received. Items travel as First-Class Mail.

Registered Mail is a highly secure form of delivery that is documented at each step of the way. Registered mail is best for sending documents or items that have an intrinsic value, where security is important. This mail is kept under lock and key during its journey. As a result, it takes longer to reach its destination.

Because of misunderstandings, Registered Mail is sometimes used by mailers who really do not require such a high level of security. Consequently, registry fees are spent and can inflate postage budgets.
