You budget for the certified mail fee. You hand your letter to the clerk. Then a second charge shows up that you did not plan for.
That second charge is the return receipt. It is optional on paper, but it is the part that gets you the signature. So how much is certified mail with return receipt, all in, for one normal letter?
For a standard 1 ounce letter, the answer is $11.02 with a mailed green card. It is $9.28 with the electronic version. Certified mail by itself, no receipt at all, is $6.37.
Those three numbers cover most senders. The rest depends on weight, which receipt type you pick, and whether you add extras like restricted delivery.
How much is certified mail with return receipt for a 1 ounce letter
Certified mail with return receipt is not one flat fee. It is three separate line items stacked together, and the clerk rings up each one on its own.
| Item | Price |
|---|---|
| First-Class Mail postage, 1 oz letter | $0.82 |
| Certified Mail fee | $5.55 |
| Return Receipt, mailed (green card) | $4.65 |
| Return Receipt, electronic | $2.91 |
Add postage, the certified fee, and your chosen receipt type. That is your total.
With the green card, it comes to $11.02. With the electronic receipt, it drops to $9.28.
Skip the receipt entirely and you pay $6.37 for certified mail by itself. Our full certified mail cost breakdown covers that base fee on its own in more depth.
These prices come straight from USPS. They are posted on the official extra services and fees page. They are the same at every post office in the country.

Green card or electronic, which one should you pick
The paper green card, PS Form 3811, gets mailed back to you after delivery. It carries the recipient’s actual signature. The electronic version arrives as a PDF by email instead, and it beats the paper card back every time.
I would grab the electronic one almost every time. It is $1.74 cheaper. It also does not have to survive its own trip through the mail, and green cards do go missing.
Courts and agencies that accept a return receipt as proof of delivery generally accept either format. The one exception is a request for the original green card with a wet signature. Some legal filings and older institutions still ask for that exact paper form, so ask before you mail.
Our return receipt guide walks through the timing and paperwork for both formats in more detail.
What changes if your letter weighs more than 1 ounce
Postage climbs $0.29 per additional ounce. The certified fee and the return receipt fee stay flat no matter how heavy the letter gets. A 2 ounce letter with certified mail and a green card runs $11.31.
A 3 ounce letter with the same combo runs $11.60. Letters cap out at 3.5 ounces. A thick stack of documents usually goes in a large envelope instead, and that changes the base postage.
A 1 ounce large envelope starts at $1.69. The same certified mail plus green card combo becomes $11.89 before any extra ounces get added.
Weigh your envelope before you get in line. Guessing at weight is the most common reason a certified mail total comes in higher than expected at the counter.
Add ons that push the price higher
Certified mail with return receipt proves your letter was delivered and signed for. It does not control who signs for it. Two extra services handle that, and both cost more than the receipt itself.
- Restricted Delivery on certified mail: $14.35. Delivery goes only to the named addressee or their authorized agent.
- Adult Signature Required: $9.70. The recipient must be 21 or older and show ID.
- Adult Signature Restricted Delivery: $10.00, which combines both controls into one fee.
Stack restricted delivery onto a certified letter with a green card receipt and a 1 ounce letter jumps to $25.37. That number surprises people. Budget for it only if your situation truly calls for restricted delivery.
Certified mail already gets a signature at delivery by default. Most senders do not need to pay extra for that part. See our breakdown on whether a signature is required at all before adding anything on top.
Do online certified mail services cost more
A little, usually. Several online services let you upload a document. They print it, mail it, and handle the certified and return receipt paperwork.
The ones I have looked at price a basic certified letter a bit above the $6.37 counter total. The return receipt is an add on from there. You are paying for the printing and for skipping the post office trip.
That is worth it if you cannot get to a post office during open hours. It also helps if you send certified mail often and want the paper trail stored for you. For a single letter, walking it into your local post office is cheaper.
Our guide to mailing certified letters online weighs that tradeoff in more detail.
When the total at the counter looks wrong
Two things throw off a certified mail total more than anything else. The first is weight. A letter that tips past 3.5 ounces gets priced as a large envelope, and anything past 13 ounces has to go Priority Mail.
The second is the receipt type getting swapped without you noticing. Ask to see the receipt before you pay if the number does not match your own math.
Certified mail fees and return receipt fees are set nationally and posted. They do not vary by ZIP code or by which post office you use. So how much is certified mail with return receipt should be identical at a big city branch and a small rural one.
Once your letter is moving, tracking is a separate question from cost. Our certified mail tracking guide covers scans after you leave the counter, and our step by step guide to sending certified mail covers the mailing process itself.
Bottom line
A standard 1 ounce certified letter with an electronic return receipt costs $9.28. Swap in the mailed green card and it is $11.02. So when someone asks how much is certified mail with return receipt for a routine letter, those two numbers are the real answer.
Every dollar past that comes from extra weight, an add on like restricted delivery, or a third party service handling the mailing for you.
