How it Works and Cost of USPS Certified Mail

The Certified Mail form contains a green and white sticker that includes a barcode, which allows mail to be tracked through the USPS. The form also contains a perforated receipt, which serves as proof that the item was mailed.

  • Write all of the required information on the form, including the recipient’s name and address.
  • Remove the backing and place the sticker along the top edge of the envelope being mailed, directly to the right of the return address area.
  • Make sure to leave room on the top right portion of the envelope to apply correct postage.
  • On a package, the sticker can be placed to the left of the address area.

With Certified Mail service, the sender receives a mailing receipt, and the mail recipient must sign for the envelope or package. The USPS keeps a copy of the recipient's signature on file as proof of delivery for two years from the date of mailing. A copy of the signature, or equivalent signature stamp can be received by purchasing the Return Receipt service when mailing the item. If the Return Receipt service is not purchased, a request of delivery proof can be made by purchasing Return Receipt After Mailing service, also known as Duplicate Return Receipt service, for up to two years. With Certified Mail, insurance cannot be purchased.

The current cost to send a 1-ounce USPS Certified Mail® letter with Return Receipt (Green Card) is now $6.70 as of Jan. 21, 2018, by first-class mail.
