Certified mail vs. return receipt: what's the difference?
Certified Mail tracks delivery. A return receipt sends you the signature.
Short answer
Certified Mail and a return receipt aren't alternatives: a return receipt is an add-on to a service like Certified Mail, not a separate way to send. Certified Mail gives you a tracking number and a USPS record of delivery.
Adding a return receipt sends you a record of who signed for it: their signature, the delivery date and the address where it was actually delivered.
What each one gives you
Certified Mail is the service; the return receipt is added to it. You can't buy a return receipt for a regular First-Class letter on its own.
| Certified Mail | Certified + return receipt | |
|---|---|---|
| Tracking number | Yes | Yes |
| Delivery or attempt date and time | Yes | Yes |
| Signature taken at delivery | Yes, kept by USPS | Yes |
| Who signed, sent to you automatically | No | Yes |
| Address where it was actually delivered | No | Yes |
| Price with Sendpaper | $14.99 | $19.99 |
In short: Certified Mail tells you when it arrived. A return receipt tells you who took it.
Green card or electronic
USPS offers two kinds of return receipt. The green card (PS Form 3811) is attached to the envelope, signed at delivery and mailed back to the address on the card. The electronic version arrives by email. Both give you the signature, the delivery date and the delivery address.
The electronic version isn't available for mail to APO/FPO/DPO addresses or US territories.
Which kind comes with a Sendpaper order, or a receipt that hasn't arrived? Email support@sendmypaper.com and we'll sort it out.
When to add a return receipt
Add one when the signature itself matters:
- The contract, lease, notice or rule you're following says "return receipt requested".
- You may need to show who received it, not just that it arrived.
- You want a delivery record you hold yourself, without looking it up later.
When Certified Mail alone is enough
Skip the return receipt when a delivery date is all you need: confirming a reply is on its way, or a rule that asks only for certified mail. Tracking shows when it was delivered or attempted, and USPS keeps the signature on file; it can email a proof of delivery letter that includes the signature when one is available.
That letter isn't the same thing as a return receipt, so if a rule specifically asks for one, buy the return receipt. If you're not sure what a rule requires, check it or ask a professional; we print and mail letters and don't give legal advice.
Common questions
Can I add a return receipt after mailing?
No. USPS sells a return receipt only at the time of mailing, so decide before you send. With Certified Mail alone, you can still look up the delivery record with the tracking number.
Is a return receipt the same as restricted delivery?
No. Restricted delivery limits who can sign for the letter. A return receipt tells you who did sign.
Does a return receipt prove what was in the envelope?
No. It records delivery and who signed, not the contents. Keep a copy of exactly what you sent.
What if no one signs for it?
USPS leaves a notice, and the recipient can pick it up or request redelivery. If it isn't claimed within 15 days, it goes back to the sender, and there's no signature to report. See what certified mail is for more.
