Certified Mail Cost in 2026: What You'll Actually Pay (and How to Pay Less)

Certified Mail costs $5.55 per piece in 2026, plus postage. With a Forever stamp ($0.82), a 1-ounce Certified letter costs $6.37. Add an electronic return receipt ($2.91) and the total is $9.28; add the green-card return receipt ($4.65) instead and it is $11.02. Certified Mail Restricted Delivery is $14.35 plus postage.

Quick answer: The Certified Mail fee pays for the mailing receipt and delivery tracking only. Postage is separate, and a return receipt (proof of who signed) is another fee on top. The cheapest way to get a signed delivery record is Certified Mail with the electronic return receipt, which costs $1.74 less per piece than the green card. These fees did not change with USPS's temporary holiday prices.

All fees below come from USPS Notice 123, the official price list (Notice 123, effective October 4, 2026), the Domestic Mail Manual section 503 and usps.com Insurance & Extra Services, all checked on November 4, 2026. Prices change, so confirm before you mail.

Certified Mail fees in 2026 (USPS Notice 123)

Every Certified Mail fee is charged per piece, in addition to postage. These are the fees USPS lists:

Certified Mail Restricted Delivery and the two Certified Mail Adult Signature options are each a single $14.35 fee that replaces the $5.55 Certified Mail fee. You don't pay both; postage and any return receipt are extra. A return receipt is not included in any of them; add it separately if you need a signature record. With the Certified Mail Adult Signature options, only the green-card return receipt can be used (DMM 503, Exhibit 1.4.1).

The current Notice 123 does not list a Return Receipt for Merchandise fee, so it is not covered here.

What certified mail actually costs: worked totals

Here is what you pay at the counter for common pieces, using the retail postage in Notice 123 (checked November 4, 2026):

A few notes on those numbers:

• Letters: stamped First-Class Mail letters are $0.82 for 1 ounce, $1.11 for 2 ounces, $1.40 for 3 ounces and $1.69 for 3.5 ounces. Letters over 3.5 ounces pay large-envelope prices. A letter that is rigid, square or otherwise nonmachinable adds a $0.49 surcharge.
• Large envelopes (flats): $1.69 for 1 ounce, $2.27 for 3 ounces and $5.24 at the 13-ounce maximum. A flat that is rigid, nonrectangular or not uniformly thick pays parcel prices instead.
• Priority Mail: the retail Flat Rate Envelope is $13.90 through January 17, 2027 under USPS's temporary holiday prices. The July 2026 Notice 123 listed it at $12.90 (July 12, 2026 Notice 123). Priority Mail by weight starts at $11.50 retail (1 lb, Zone 1) on the current list.
• Restricted Delivery: a 1-ounce stamped letter with Certified Mail Restricted Delivery is $15.17, or $18.08 with an electronic return receipt and $19.82 with a green card.

Which mail classes can you send certified?

Certified Mail can be added to First-Class Mail (letters and large envelopes) and Priority Mail only. The DMM eligibility table lists just those two classes, and the comparison chart on usps.com says the same (usps.com). You cannot add Certified Mail to USPS Ground Advantage, Media Mail or Priority Mail Express. The Adult Signature versions of Certified Mail are available with Priority Mail only.

Certified Mail itself is not insurance. The DMM says no insurance coverage is provided with Certified Mail, except for Priority Mail pieces that come with included insurance (DMM 503.3.1.1). If you're mailing something valuable, look at insured mail or Registered Mail (from $20.90 plus postage) instead. See our guide to USPS shipping insurance costs and claims.

Green card vs electronic return receipt

Certified Mail on its own gives you a mailing receipt and an online delivery status. It does not give you the recipient's signature. For that you add a return receipt, bought at the time of mailing, in one of two forms:

• Hardcopy (green card, PS Form 3811), $4.65: the signed card is mailed back to you. The mailpiece must be endorsed "Return Receipt Requested."
• Electronic, $2.91: you get the delivery record, including the signature, by email. No endorsement is needed. It is not available to APO/FPO/DPO addresses, U.S. territories and possessions, or the Freely Associated States.

DMM 503 says a return receipt gives "evidence of delivery (to whom the mail was delivered and date of delivery)" and the recipient's actual delivery address (DMM 503.6.1.1). Some contracts, court rules and government notices specify how a document must be sent, and a few may call for the physical green card. Check the requirement that applies to you before choosing; this article is not legal advice.

If you paid for a green card and it never came back, DMM 503.6.3 lets you ask for the delivery information within 90 days of purchase using PS Form 3811-A at any Post Office, with your receipt showing you paid the return receipt fee.

Buying certified mail at the counter vs online

USPS publishes one Certified Mail fee. Notice 123 does not list a separate online or commercial price for Certified Mail or return receipts, so the $5.55, $2.91 and $4.65 fees are the same wherever you buy. What can change is the postage.

The main postage saving online is metered or PC Postage letter postage: $0.78 for a 1-ounce metered letter versus $0.82 with a stamp, a $0.04 difference per piece. Stamps.com markets "discounted Certified Mail rates" (Stamps.com). The USPS price list shows only one Certified Mail fee, so any discount there comes from the postage, not the Certified fee. For a business sending a handful of Certified letters a month, a $0.04 saving won't cover a $29.99 monthly plan. The case for PC Postage is convenience and volume, not the price of one letter.

Getting proof of delivery and keeping records

• Online status: delivery information for Certified Mail can be looked up by article number on usps.com or by calling 1-800-222-1811, and USPS can email a proof-of-delivery letter, including a signature when one is available (DMM 503.1.8).
• Your receipt: the PS Form 3800 receipt is your proof of mailing. Ask the clerk to round-date it if you want a postmarked receipt.
• Longer history: USPS Tracking Plus extends tracking history for up to 10 years, starting at $2.50, and is available for First-Class Mail letters and flats bought with a trackable extra service such as Certified Mail (usps.com).

The DMM says USPS keeps a record of delivery, including the recipient's signature, for Certified Mail, but we did not find a stated retention period for Certified Mail on the USPS pages we checked. If you need the record for years, keep your own copy: save the electronic return receipt PDF or file the green card, and consider Tracking Plus.

How the 2026 price changes affected certified mail

July 12, 2026: USPS's mailing-services price change took the Forever stamp from 78 to 82 cents and the 1-ounce metered letter from 74 to 78 cents (USPS, April 9, 2026). Certified Mail fees went up at the same time. Comparing the Notice 123 effective April 26, 2026 (USPS archive) with the July 12 edition:

October 4, 2026 to January 17, 2027: USPS's temporary holiday price change applies only to Priority Mail Express, Priority Mail, USPS Ground Advantage and Parcel Select. USPS's announcement says "No other products or services would be affected" (USPS, August 25, 2026). Certified Mail, return receipts and First-Class Mail letters and flats are not affected. If you send Certified Mail by Priority Mail, the postage is higher during that window; the retail Flat Rate Envelope, for example, went from $12.90 to $13.90. See our post on the USPS peak season surcharge.

As of November 4, 2026, USPS's price change page lists only the time-limited holiday change. Check Notice 123 again in January, and see our roundup of 2027 shipping rate increases.

How to pay less for certified mail

1. Choose the electronic return receipt. It is $2.91 versus $4.65 for the green card, a saving of $1.74 per piece, or $174.00 on 100 letters, unless a rule you have to follow calls for the physical card.
2. Skip Restricted Delivery unless it's required. Certified Mail Restricted Delivery is $14.35 versus $5.55, so it adds $8.80 per piece. Use it only when delivery must go to a named individual.
3. Don't add a return receipt you won't use. If you only need proof that you mailed something and the delivery status, Certified Mail alone ($6.37 for a 1-ounce letter) may be enough. If you only need proof of mailing, a Certificate of Mailing is $2.45 plus postage, but it provides no delivery information.
4. Keep it a letter if you can. A 3-ounce letter costs $1.40 in postage; the same weight as a large envelope is $2.27. Folding documents into a standard letter envelope saves $0.87 each.
5. Use First-Class Mail, not Priority Mail, for documents. A 1-ounce Certified letter with an electronic return receipt is $9.28; the same services on a retail Priority Mail Flat Rate Envelope are $22.36 during the holiday price period.
6. Buy postage online if you mail in volume. Metered and PC Postage letters are $0.78 instead of $0.82. That only pays off once the savings cover any subscription fee.

If you also ship packages that need a signature, compare those options in our guide to USPS Signature Confirmation and Adult Signature fees. Signature Confirmation is for packages; it is not available for First-Class Mail letters.

For a 1-ounce letter, $9.28 with an electronic return receipt ($2.91) or $11.02 with the hardcopy green card, PS Form 3811 ($4.65). Heavier letters, large envelopes and Priority Mail cost more because the postage is higher.

No. USPS's temporary price change from October 4, 2026 to January 17, 2027 applies only to Priority Mail Express, Priority Mail, USPS Ground Advantage and Parcel Select. The Certified Mail fee, return receipt fees and First-Class Mail stamp prices are unchanged. It does raise the postage if you send Certified Mail by Priority Mail.

Can I buy certified mail online?

USPS's extra-services page says to purchase Certified Mail at a Post Office. Some PC Postage providers support it: Stamps.com includes Certified Mail on its Professional plan (from $29.99 a month on November 4, 2026). Pirate Ship says it does not offer Certified Mail.

The bottom line

In 2026, Certified Mail is $5.55 plus postage, and a signed delivery record adds $2.91 electronically or $4.65 for the green card. For most routine letters, Certified Mail with the electronic return receipt ($9.28 for a 1-ounce letter) gets you the proof at the lowest price. Pay for the green card or Restricted Delivery only when a requirement calls for it. Small fees like these add up across a year of mailings.
