To fill out USPS Form 3811, print the recipient’s name and address in Item 1, stick or write the Certified Mail article number in Item 2, check the matching service type in Item 3, and print your own return address on the back of the card. Use ink, not pencil, and match the recipient information to what appears on the envelope exactly. The card itself is free at any post office counter; the return receipt service costs $4.40 for the physical green card on top of your postage and Certified Mail fee.1USPS. Notice 123 – Price List
Where to Get the Card
Ask any post office clerk for PS Form 3811 or “a green return receipt card.” USPS also posts a printable PDF at about.usps.com/forms/ps3811.pdf.2USPS. PS Form 3811 – Domestic Return Receipt If you print your own, use heavy cardstock. A flimsy printout tends to tear off the envelope inside sorting machines, and if it separates in transit, no one gets a signature and no one gets it back.
Front Side: Items 1, 2, and 3
The front of the card has three numbered boxes. Complete all three before you hand the mailpiece to the clerk.
Item 1: Article Addressed To
Print the recipient’s full name and complete delivery address, matching the envelope word-for-word. If you’re mailing to “The Parent or Guardian of” a minor, write that line here too. A mismatch between the card and the envelope can cause the carrier to skip the signature step at delivery.
Item 2: Article Number
Copy the barcode number from your Certified Mail label (or Registered Mail label, COD tag, or insured mail label) into this box. Most Certified Mail labels sold at the post office include a peel-off barcode sticker sized to fit Item 2. If yours has one, peel it and press it in place rather than transcribing the 20-digit number by hand. Hand-copying is where most errors happen.3Penn State Multimedia and Print Center. Certified Mail Instructions
Item 3: Service Type
Check the box that matches the extra service you paid for. Certified Mail is the most common choice. Other options include Registered Mail, Collect on Delivery, and insured mail over $500. Check only one. Don’t check “Return Receipt for Merchandise” unless you specifically paid for that separate service.
Item 3 also contains a Restricted Delivery checkbox. Check it only if you paid the Restricted Delivery fee (more on that below).
Back Side: Your Return Address
Flip the card over and print your own name and mailing address. This is where USPS mails the signed card after delivery. If the back is blank or illegible, the signed receipt has nowhere to go. Double-check the ZIP code before you attach the card.
Attaching the Card to the Envelope
The back of the card carries two adhesive strips along its edges. Peel the backing off both, then press the card firmly onto the back of the envelope with the front of the card (Items 1–3) facing outward. On packages too small or oddly shaped for the back, you can attach the card to the front, as long as it doesn’t cover the delivery address, postage, or Certified Mail barcode.
Take the completed mailpiece to the counter. The clerk rings up your postage, your Certified Mail fee, and your Return Receipt fee together, then hands you a mailing receipt. Keep that receipt. It’s your proof the item entered the mail system, and if the green card never returns, the article number on it is what you’ll need to pull tracking or request a duplicate.
What It Costs
The card itself is free. The Return Receipt service that sends it back to you signed is $4.40 for the physical green card, or $2.82 for the electronic version. Certified Mail adds another $5.30, so a typical Certified Mail piece with a physical return receipt runs $9.70 in add-on fees before postage.1USPS. Notice 123 – Price List
The Restricted Delivery Option
Restricted Delivery is a separate service you can add, and it gets its own checkbox on Form 3811. Without it, any competent person at the delivery address can sign for the mail. With it, the carrier can hand the piece only to the named addressee or someone that person has authorized in writing.4USPS. Domestic Mail Manual S916 Restricted Delivery
The service costs $13.70 on top of Certified Mail and postage, so it makes sense only when you need proof a specific individual received the document rather than just someone at their address.1USPS. Notice 123 – Price List Eviction notices, demand letters, and cease-and-desist letters are typical uses.
A few exceptions apply. Mail addressed to a minor can be delivered to a parent or guardian. Mail to an inmate can go to the warden if the inmate can’t sign personally. Mail to government officials can be accepted by someone authorized under that agency’s internal procedures.4USPS. Domestic Mail Manual S916 Restricted Delivery If the addressee wants a regular stand-in, they can file USPS Form 3801 with their local post office designating an authorized agent.
The Electronic Alternative
If you don’t need the physical postcard, you can buy an electronic return receipt for $2.82 instead of $4.40.1USPS. Notice 123 – Price List You purchase it at the counter the same way, but no card gets attached. The carrier captures the recipient’s signature electronically on PS Form 3849 at delivery. You then go to usps.com, use Track & Confirm with your article number, and request the electronic receipt. USPS emails you a PDF showing the delivery date, time, and an image of the signature.5USPS. Domestic Mail Section – Electronic Return Receipt
One caution: some courts and agencies specifically require the original signed green card, not a PDF. Check your filing requirements before going paperless.
What Comes Back to You
At delivery, the carrier asks the recipient (or authorized agent) to sign the front of the card and write the delivery date. The carrier peels the card off the envelope and drops it into the outgoing mail. The card is pre-printed with First-Class postage indicia, so it travels back to you as a postcard using the return address you wrote on the back. It usually arrives in your mailbox within one to two weeks after delivery.
When it shows up, the card carries three things: the recipient’s signature, the date of delivery, and the article number linking it to your original mailpiece. File it with your copy of what you sent and your original mailing receipt from the post office.
If the Card Doesn’t Come Back
Cards sometimes get lost on the return trip. If yours hasn’t arrived within 30 days of the delivery date shown in tracking, check USPS Tracking online with the article number from your mailing receipt. If tracking confirms delivery, ask your local post office to file a search request for a duplicate. The electronic tracking record with a delivered status and signature on file isn’t as clean as the physical card, but it holds up as evidence of delivery in most contexts.
