What Does Certified Mail Restricted Delivery Mean?

Certified Mail Restricted Delivery is a U.S. Postal Service option that guarantees your letter or document is handed to one specific named person and no one else. Regular certified mail collects a signature from whoever answers the door; adding restricted delivery tells the carrier to release the item only to the addressee, after verifying their identity. As of the January 18, 2026 price schedule, the combined service costs $13.70 on top of first-class postage, and it produces the kind of paper trail that holds up in court when you need to prove a particular individual personally received a document.¹

What Restricted Delivery Adds to Certified Mail

Certified mail on its own gives you three things: a receipt proving you mailed the item, a tracking number, and a signature captured at delivery. USPS keeps an electronic record of that signature. For many senders that’s enough. But it leaves a gap. Anyone at the delivery address can sign, so a roommate, a receptionist, or an adult family member can accept the piece, and you have no guarantee the intended person ever laid eyes on it.

Restricted delivery closes that gap. The carrier is instructed to release the item only to the addressee, or to someone the addressee has authorized in advance, and to verify identity before handing anything over. The addressee has to be a specific individual named on the envelope, not a business, department, or generic title. What you end up with is a verifiable chain: you sent the document, USPS delivered it, and the named person personally signed for it.

Who Is Allowed to Sign

Only the person whose name appears on the envelope can accept and sign for a restricted delivery item, and the carrier checks identification before releasing it.² A spouse, an assistant, or a neighbor cannot take the letter on the addressee’s behalf just by being present.

Two narrow exceptions exist, and both require the recipient to act. The addressee can name a permanent authorized agent by filing PS Form 3801 (a Standing Delivery Order) at their local post office; that agent is then allowed to sign for restricted delivery mail going forward.² Or, if the carrier has left a PS Form 3849 notice because no one was available, the addressee can use that notice to authorize a specific person to pick up that one mailpiece from the post office. Neither exception happens on its own.

Don’t Confuse It With Adult Signature Restricted Delivery

USPS offers a separate service called Adult Signature Restricted Delivery. It works like Certified Mail Restricted Delivery in that only the addressee can sign, but it also adds an age requirement: the recipient must be at least 21, and the carrier requires a government-issued photo ID to verify both identity and age. It’s used mainly for shipping age-restricted products like alcohol or tobacco, not for legal correspondence. A related but looser option, “Adult Signature Required,” lets any adult at the address sign with valid ID; it does not have to be the addressee.³

When People Use It

Most people encounter restricted delivery in legal or regulatory contexts, where a sender needs ironclad proof that a specific individual was personally notified. The extra dollars over standard certified mail buy protection against the common excuse of “I never got it.” Common uses include:

Legal service of process. Courts and attorneys use it for summonses, complaints, and subpoenas. Federal Rule of Civil Procedure 4 requires certified or registered mail for serving certain parties, including federal agencies and U.S. attorneys’ offices.⁴
Contract and lease terminations. Many agreements require written notice delivered to a named party, and restricted delivery proves the right person received the letter on a specific date.
Debt collection notices. Creditors sending formal demand letters or legally required disclosures use it to show the debtor personally received the notice.
Government correspondence. Federal and state agencies use it for tax notices, enforcement actions, and other communications where personal delivery to the recipient is a legal prerequisite.

If you only need proof that something reached an address and don’t care who signed, standard certified mail at $5.30 is cheaper and does the job. Restricted delivery solves the narrower problem of confirming a named person had the document placed in their hands.

What It Costs in 2026

The USPS fee schedule effective January 18, 2026 sets Certified Mail Restricted Delivery at $13.70 per item. That one fee covers both the certified mail piece and the restricted delivery piece; they aren’t billed separately.¹ Compared with standard certified mail at $5.30, the restricted delivery upgrade effectively adds $8.40.

On top of that you pay first-class postage and, usually, a return receipt fee so you actually get the signature back:

Certified Mail Restricted Delivery: $13.70
First-class postage (1 oz letter): $0.78
Physical return receipt (green card, PS Form 3811): $4.40
Electronic return receipt (signature emailed to you): $2.82

A fully loaded mailing with the physical green card runs about $18.88; using the electronic return receipt instead brings it to roughly $17.30.¹ Both return receipt formats carry the same legal weight; the electronic one arrives faster and is stored by USPS for two years from the mailing date, though records older than 60 days take longer to retrieve.⁵ The physical card is useful when you need an original signed document to file with a court.

How to Send One

You have to go to a post office counter. Certified Mail Restricted Delivery is not available through USPS online retail tools like Click-N-Ship under the current Domestic Mail Manual.⁶

Pick up PS Form 3800, the green-and-white certified mail receipt label that attaches to your envelope and carries the tracking number.⁷ If you want a return receipt, grab PS Form 3811, the green card that travels with your letter and comes back with the recipient’s signature.⁸

Check the “Restricted Delivery” box on the forms, and write “Restricted Delivery” above the delivery address on the envelope itself. Address the piece to a specific individual, not a company or department.⁶ Hand everything to the retail clerk, who postmarks the sender’s portion of PS Form 3800. That postmark is what makes the receipt accepted as legal proof of mailing, so don’t drop the envelope in a collection box instead.⁷

What Happens If the Addressee Isn’t Home

If the carrier attempts delivery and the addressee isn’t available, the item is not left behind. The carrier leaves a PS Form 3849 notice in the mailbox letting the recipient know certified mail is being held at the local post office.⁹ The recipient has 15 days to pick it up, in person and with valid identification. Because this is restricted delivery, they generally cannot send someone else unless they’ve set up an authorized agent through PS Form 3801 or written authorization on the PS Form 3849 itself.

If the addressee refuses the letter at the door, the carrier notes it as a refusal. If the item sits unclaimed past the holding period, USPS returns it to the sender. In either case the returned envelope is endorsed with the reason for non-delivery, such as “Refused” or “Unclaimed.”¹⁰ That endorsement becomes part of the sender’s documentation, and in many legal contexts a proper mailing that came back “Refused” or “Unclaimed” is still treated as having put the recipient on notice.
