What is a Certified Mail Receipt?

A Certified Mail Receipt, also known as PS Form 3800, is a slip of paper that has a unique Certified Mail tracking number and bar code printed on it.  Half of the document is a receipt showing that you mailed a Certified Letter, the other half is a bar code and tracking number is placed on and over the top of the letter you are sending.  The receipt portion proves that you mailed a piece of Certified Mail.

This document is needed before you can actually mail your letter.  You can pick them up at your local Post Office or order them online at USPS.com.

If going to the Post Office for supplies sounds like a lot of work; LetterStream's process does not require you to use the PS Form 3800, and you don't need to go to the Post Office or fill out any forms.  Simply log in to LetterStream and upload your document, we'll take care of all the rest.
