How to Track Certified Mail (and Get Proof It Was Delivered)
How to track Certified Mail in four steps
- Find the tracking number. It is the 20-digit number under the barcode on your PS Form 3800 receipt, on the label if you printed it online, or in your account if you used a Certified Mail service.
- Enter it at USPS.com. Go to USPS Tracking and paste the number. You can also text the number to 28777 (2USPS) or use the USPS Mobile app.
- Read the status. Acceptance, In Transit, Out for Delivery, Delivery Attempt, and Delivered are the ones that matter. Notice Left means the carrier could not get a signature and the piece is being held at the Post Office.
- Get your proof. Tracking shows that the piece was delivered. If you need the signature, you must have added Return Receipt when you mailed it; the signed green card comes back by mail, or the Return Receipt Electronic PDF is posted to your account.
USPS keeps Certified Mail tracking records for two years. Save your receipt or download the records if you may need them later.
Where the Certified Mail tracking number comes from
Every Certified Mail piece gets a unique 20-digit USPS tracking number when the barcode is created. At the Post Office that happens when the clerk applies the PS Form 3800 sticker; online it happens when the label is printed. The number is the same one that appears on your Proof of Acceptance, on the Return Receipt, and in USPS Tracking, so one number ties the whole record together. If you lose the receipt and did not mail online, USPS cannot look up the piece for you; a Certified Mail account keeps the number searchable by recipient name, date, or reference for 10 years.
Key Takeaways:
- You track Certified Mail with the 20-digit number on your PS Form 3800 receipt or label, at USPS.com, by text to 28777, or in the USPS Mobile app.
- USPS Tracking shows delivery status only. To get the recipient’s signature you need Return Receipt, added at mailing time.
- All tracking and receipt documents in a Certified Mail account are stored for 10 years and are searchable by recipient name, tracking number, delivery date, and other delivery confirmation details.
If you send more than a few pieces a month, a Certified Mail service does the tracking for you. Here is what SimpleCertifiedMail.com adds on top of USPS Tracking:
The process begins with printing Certified Mail cover sheets from any standard office printer, complete with electronic postage and the USPS barcodes required to track Certified Mail (see image below). Fold and insert the cover sheets into the USPS approved window envelopes we provide, along with your letters. Then simply drop your Certified Mail letters in any USPS Mailbox or leave them for your Mail Carrier to pick up. This makes it easier for offices to prepare Certified Mail without juggling handwritten forms, separate shipping labels, or trips to the Post Office.
Proof of Acceptance within hours of mailing
You receive electronic Proof of Acceptance within hours of mailing your Certified Mail — no PS Form 3800, scan forms, firm books, manifests, or Post Office visits required. A Proof of Acceptance (Electronic) PDF file (see image below) for each Certified Mail piece is posted to your account soon after the letter receives its first outbound scan at a USPS facility. This PDF file is accepted by state and federal courts as prima facie evidence that the Postal Service physically took possession of your mail.
For teams that need immediate tracking updates, this is an efficient way to confirm that a piece has entered the USPS system and is now in transit. Because the record is electronic, it is easy to produce for a court, auditor, or regulator years later.
Once your mail pieces are in the mail stream, SimpleCertifiedMail.com captures the USPS tracking events as your mail pieces make their way through the USPS network, and displays the most relevant information in its Delivery Information screen, including tracking statuses such as in transit, out for delivery, delivery attempt, and final delivery.
Return Receipt Electronic within 24 hours of delivery
For Certified Mail requiring proof of delivery with a signature, the USPS Return Receipt Electronic is posted to your account within 24 hours, eliminating the inconveniences of using Green Cards. The Return Receipt (Electronic) is the Postal Service’s electronic alternative to the PS Form 3811 Green Card, with the same legal standing as the PS Form 3811 Green Card, just much more convenient. The PDF file is posted to your account within 24 hours of the Mail Carrier delivering your Certified Mail letter and receiving a signature from the recipient. It is stored in your account for 10 years, and can be downloaded to your own server, and printed at any time. In addition, a box on the form contains the Recipient’s name, address and any reference text you entered before sending the Certified letter providing a match of the Certified Mail item number to the Addressee.
For mailers sending legal, compliance, or time-sensitive documents, this visibility can be especially useful when Restricted Delivery or signature-based proof is required.
The Return Receipt Electronic eliminates filling out Green Cards by hand and waiting days for Green Cards to come back after mailing your Certified letters. It eliminates the risk that Green Cards get lost in the mail, requiring a second Certified Mail letter to be sent. And of course it means no stuffing file cabinets and closets with Green Cards, and having to hold on to them for years.
Proof of Delivery for pieces without a signature
For Certified Mail pieces not requiring a signature, you receive a Proof of Delivery (Electronic) PDF file, also within 24 hours. The Proof of Delivery (Electronic) PDF file provides the city, state, time and date the Certified Mail® piece was delivered. It is posted to your account within 24 hours to make sure you have a full tracking history, Acceptance and Delivery, for every mail piece. (See sample below.)
Importantly, the Delivery Information screen in the SimpleCertifiedMail.com online software enables you to search for specific mail pieces, and groups of mail pieces. Your search options include: Recipient Name, Sender Name, Tracking Number, Reference, Date Created Between, Date Received Between, Ten Day Report, and Undelivered Report. This gives users one place to review tracking statuses, delivery confirmation records, and historical tracking updates without sorting through paper files.
What each Certified Mail tracking status means
- Accepted — USPS has the piece; your Proof of Acceptance is generated
- In Transit
- Out for Delivery — at the local delivery unit
- Delivery Attempt / Notice Left — no one available to sign; held at the Post Office
- Delivered
- Return to Sender — unclaimed
These updates provide useful context when a recipient says a letter never arrived. If only a named person may sign, add Restricted Delivery when you mail; tracking will show the attempt if someone else tries to accept it.
FAQ
Can you track a Certified Mail letter?
Yes. Certified Mail is one of the few letter services USPS tracks, because the barcode on the label is scanned at acceptance, in transit, and at delivery.
Can the recipient track Certified Mail?
Yes, with the tracking number. Anyone who has the number can see the same status at USPS.com.
Why has my Certified Mail tracking not updated?
Letters are scanned less often than packages, so a gap of a day or two between scans is normal. If there has been no update for a week, check USPS Service Alerts for your area, then contact USPS with the tracking number.
Does tracking show the signature?
No. USPS Tracking shows that a piece was delivered, not who signed. The signature only comes back to you through Return Receipt, either the green card or the electronic PDF. See Certified Mail vs. Certified Mail Return Receipt.
