What are USPS Certified Mail labels?

USPS Certified Mail label’ refers to two different USPS items. Most people mean PS Form 3800, the barcoded Certified Mail receipt you get at the Post Office counter. USPS also sells Label 3800-N, a non-barcoded green label used only on parcels that already carry a prepaid IMpb shipping label. Both provide a mailing receipt, USPS Tracking, and a record of delivery or attempted delivery when used correctly.

Which USPS Certified Mail label do you need?

There are two different things called a Certified Mail label, and they are not interchangeable. Choosing the wrong one is the most common reason a Certified Mail piece is delayed or returned.

PS Form 3800, the Certified Mail receipt. This is the barcoded form a retail clerk hands you at the Post Office counter. You write the recipient address by hand, the clerk peels the barcode strip onto your envelope, and you keep the stamped remainder as your Proof of Acceptance.

Label 3800-N, the green Certified Mail Label. This is the non-barcoded, color-coded green label USPS sells in rolls of 600 through the Postal Store. It carries no tracking number of its own. USPS states it is for use only with an Intelligent Mail package barcode (IMpb) shipping label with postage prepaid, which means it only marks a parcel as Certified Mail alongside a separate prepaid shipping label.

A SimpleCertifiedMail.com label, the online alternative. You create the label in your browser and print the recipient address, the digital postage, and the Certified Mail barcode together on one piece. It replaces PS Form 3800 for letters, flats, and parcels, with no counter visit and no form to complete by hand.

Where do you get Certified Mail labels, and are they free?

The label stock is free. The postage and the Certified Mail fee are not.

At the Post Office. Ask for PS Form 3800 at the counter. There is no charge for the form. You pay First-Class Mail postage plus the Certified Mail fee when you mail the piece.

From the USPS Postal Store. Label 3800-N ships free in a roll of 600 self-adhesive labels, limit one roll per order. The label is free, the postage is not, and because this label has no barcode it must be paired with a prepaid IMpb shipping label.

From your own printer. With SimpleCertifiedMail.com there is no label stock to order and no form to pick up. You print the cover sheet or adhesive label with postage already applied, and Certified Mail window envelopes are supplied at no charge.

So when people ask whether USPS gives out free Certified Mail labels, the answer is yes for the label stock and no for the postage.

A note on the October 2026 USPS label changes. USPS is retiring Label 888, Label 889, Label 891, and Label 892 on October 31, 2026. PS Form 3800 and Certified Mail service are not part of that announcement. If your team stocks any of the retiring labels, see which labels are affected and what to do before the cutoff.

They provide a mailing receipt, USPS Tracking, and a record of delivery or attempted delivery. Certified Mail is often used for legal, tax, and official documents when proof of mailing is required.

You might be wondering, what a Certified Mail label looks like. Typically, a Certified Mail letter is sent in a regular envelope with a USPS sticker (known as the PS Form 3800) that indicates the item is Certified Mail and includes a barcode for tracking.

When sending Certified Mail at the Post Office counter, the postal clerk provides a PS Form 3800 (Certified Mail label) for the sender to complete, including the delivery address and type of Certified Mail service chosen. After paying the Certified Mail fees, the postal employee attaches the barcode portion of the label to the envelope and then will stamp the other half, providing it to you as a Proof of Acceptance receipt. The Proof of Acceptance receipt includes a 22-digit tracking number you can enter on the USPS.com website to track delivery of your letter.

Need Proof of Delivery with a signature? Add Return Receipt.

Mailers can purchase an additional service at the time of mailing called a Return Receipt if their business or legal matter requires an official signature confirming the Certified Mail was delivered. The mailer fills out the USPS PS Form 3811, commonly referred to as the Green Card, and then attaches it to the back of the envelope. The Green Card includes a section for the recipient to sign once it is delivered by the USPS mail carrier. After a signature is captured, the Mail Carrier mails the Return Receipt postcard back to the original sender for Proof of Delivery (POD).

Some downsides to this option include waiting several days for the Green Card to be returned, cards getting lost in the mail, cards needing to be physically stored for record, and the original card serving as the only valid legal form of signature documentation (scans or copies of the card are not valid in court.)

The USPS also offers a Return Receipt Electronic which provides a PDF file that is universally accepted as a legal equivalent to the Green Card. Mailers can download the Return Receipt Electronic from the USPS web site by entering the 22-digit tracking number, then save it on their computer. Once downloaded the Return Receipt Electronic can be emailed and printed in multiple copies.

How to attach Certified Mail labels to an envelope, flat, or parcel

The right setup depends on what you are mailing.

For letters

Print the cover sheet on plain paper and place it inside a certified mail window envelope so the address, postage, and barcode show through the window.

For flats

Print the adhesive label and place it flat on the address side of the mailpiece.

For parcels and boxes

Print the adhesive label and place it squarely on the largest flat side of the parcel. Keep the label flat, keep the barcode easy to scan, and do not fold the label over an edge or place tape over the barcode.

For Priority Mail packaging

If you are mailing with Priority Mail, place the label on the outside of the Priority Mail envelope or box and make sure old labels or barcodes are removed or covered.

What records do you get after mailing?

SimpleCertifiedMail.com helps you keep all of your mailing records in one place.

Proof of mail receipt

This is your Electronic Proof of Acceptance. It shows that USPS accepted the item into the mailstream.

Tracking events

You can follow the key USPS tracking events for each mailpiece, including acceptance scans, in-transit updates, delivery attempt events, and final delivery.

Delivery confirmation

When the item is delivered, your account shows the delivery result.

Electronic Return Receipt

If you added Return Receipt Electronic, your account posts the USPS signature record after delivery.

Postage receipt and mailing costs

Many mailers use the term postage receipt. In SimpleCertifiedMail.com, the main USPS proof is the Electronic Proof of Acceptance, and your account also stores the mailing cost details for each piece.

Printer and label information

SimpleCertifiedMail.com works with standard home and office printers.

• Letters can be printed on plain paper cover sheets and inserted into certified mail window envelopes.
• Flats and parcels can use adhesive labels.

If your office tracks supplies by template number, use the approved certified mail label stock listed by your team. If you do not use a separate template number, say that clearly so users know the platform generates the label layout automatically.
