Sending a certified letter with a return receipt through USPS costs between $8.86 and $10.48 for a standard one-ounce letter, based on the price schedule that took effect July 13, 2025. The exact figure depends on whether you choose an electronic return receipt or the physical green card, and whether you buy postage at the retail stamp price or through a meter. Every certified return receipt letter cost is really three fees stacked together: First-Class postage, the Certified Mail fee, and the Return Receipt fee.1United States Postal Service.

What You Pay, Line by Line
The total is built from three separate charges. Each one covers a different piece of the service.
- First-Class Mail postage for a one-ounce letter: $0.78 at the retail stamp price, or $0.74 with metered postage. Each additional ounce adds $0.29.
- Certified Mail fee: $5.30 per item, on top of postage.
- Return Receipt, physical green card: $4.40 for a hard-copy PS Form 3811 mailed back to you with the recipient’s signature.
- Return Receipt, electronic: $2.82 for a digital delivery notification emailed to you, including a signature image and delivery date.
Add the pieces together and you get the two common totals. A one-ounce retail-stamp letter with the physical green card runs $10.48 ($0.78 + $5.30 + $4.40). Switching to metered postage and the electronic return receipt drops the total to $8.86 ($0.74 + $5.30 + $2.82).1United States Postal Service. Notice 123 Price List
Optional Add-Ons That Raise the Price
Two extras can push the cost higher. Restricted Delivery for Certified Mail costs an additional $13.70 and requires the carrier to hand the letter only to the specific person you addressed it to, blocking a roommate, office assistant, or family member from signing. Adult Signature, also $13.70, requires the person signing to be at least 21.1United States Postal Service. Notice 123 Price List
A fully loaded one-ounce letter with Certified Mail, a physical return receipt, and Restricted Delivery totals $24.18 ($0.78 + $5.30 + $4.40 + $13.70). That is a lot for a single envelope, but it is still cheaper than hiring a process server when you need to prove a particular individual received a document.
How to Keep the Cost Down
A few choices trim the total without giving up the proof of delivery.
- Pick the electronic return receipt. At $2.82 instead of $4.40, you save $1.58 per letter, and the digital record arrives faster than a green card traveling back through the mail.
- Use metered postage. Metered mail runs $0.04 less per letter than retail stamps. Small on one piece, meaningful in volume.
- Skip Restricted Delivery unless you truly need it. At $13.70, it more than doubles the base cost. For most purposes, a return receipt showing that someone at the address signed is enough.
The floor for a single certified return receipt letter is $8.86 with metered postage and an electronic return receipt. The ceiling for a one-ounce letter with every add-on tops $24, though few situations call for all of them at once.1United States Postal Service. Notice 123 Price List
What the Fees Buy You
You leave the counter with two things: a dated mailing receipt and a unique tracking number. The tracking number lets you follow the letter online. The receipt, when postmarked by the clerk, serves as legal proof of the mailing date.3United States Postal Service. PS Form 3800 – Certified Mail Receipt
The return receipt arrives after delivery. The physical version comes back through the mail with the recipient’s signature and the delivery date on the green card. The electronic version arrives by email as a PDF containing the delivery date and an image of the signature captured at delivery.4United States Postal Service. Return Receipt – The Basics
Together, the mailing receipt and return receipt form a chain: one proves when you sent the letter, the other proves who signed for it and when. Courts and government agencies routinely accept that pairing.
If the Letter Comes Back, You Still Pay
Certified mail requires a signature, so the carrier will not leave it at the door. When no one is home, the carrier leaves a notice (PS Form 3849) and the letter goes to the local post office for pickup. The recipient has about 15 days to claim it. If they do not, USPS sends it back to you marked unclaimed.
A recipient can also refuse to sign. The letter is then returned marked refused. Either way, you do not get a refund on the Certified Mail or Return Receipt fees. USPS treats the service as rendered once it has been attempted. The tracking record still documents what happened, and in many jurisdictions a properly addressed certified letter that comes back refused or unclaimed can support a claim of constructive notice.
