What Is a Certified Mail Receipt?

A Certified Mail Receipt (also known as PS Form 3800 or the green card) is a physical slip with a unique tracking number and barcode:

  • Serves as proof that a Certified Mail piece was sent.
  • Available at USPS locations or can be ordered online at USPS.com.

If you're using LetterStream, there's no need to visit the Post Office—everything is automated, and Certified Mail receipts are handled digitally within your account.

What Is an Electronic Return Receipt (ERR)?

An Electronic Return Receipt (ERR) is:

  • A digital signature file provided by USPS upon successful delivery of Certified Mail.
  • An official USPS product that serves as proof of delivery without the need for a physical green card.
  • Automatically stored and accessible in your LetterStream account indefinitely.

Key Benefits:

  • No waiting for mail to return.
  • Easy access and permanent digital storage.
  • Usually available within a few days of successful delivery.

Will the USPS Always Capture a Signature?

Yes—USPS policy requires a signature for all Certified Mail deliveries:

  • Signature is captured by USPS whether or not you’ve paid for the ERR.
  • If you pay for the ERR, you’ll receive access to the electronic signature file in your account.
  • If you do not pay for the ERR, you won’t be able to access the signature file later—even though one was likely captured.

Additional Notes:

  • If delivery is unsuccessful, no signature will be provided.
  • PO Box deliveries still require a signature—recipients may sign at the front desk to receive the item.
  • USPS considers Certified Mail to be Accountable Mail, which requires a signature regardless of ERR purchase. Click here for more.

Pricing

An Electronic Return Receipt (ERR) is $2.82 per recipient. If you do not need a signature, you can opt out.
