First Class Mail tracking for stamped letters

Does First Class Mail have tracking?

A First Class letter, postcard or large envelope gets no tracking number from USPS, so usps.com has nothing to show you for it. The tracked product that once shared the name, First Class Package Service, became USPS Ground Advantage in July 2023, which is why older advice to buy "First Class Package" for tracking no longer works.

USPS does scan nearly every letter its machines sort. Those machines read the address, and they also read a USPS Intelligent Mail barcode when the envelope carries one. That barcode holds a number unique to the letter, so each plant that sorts it records a scan for it. Printing that barcode on a letter you stamp yourself is how third party letter tracking works, and it is the cheapest way to follow a First Class letter.

How does a barcode on a stamped letter get tracked?

An Intelligent Mail barcode is 65 short and tall bars printed above the address. It carries a USPS Mailer ID, a serial number for the letter and the ZIP code it is going to. Big companies have printed these barcodes on their bills and statements for years. A letter tracking service like PigeonTrail or LetterTrack prints one on a single letter under its own Mailer ID, reads the scans USPS reports for it, and shows them to you.

With PigeonTrail you type or paste the address, print the envelope or a label on your own printer, add a Forever stamp and mail it anywhere a letter can go. Each barcode is drawn on our server for that one letter, so no two letters share a number. Our guide to the Intelligent Mail barcode explains the bars, and our LetterTrack comparison sets the two services side by side.

What do the scans on a First Class letter look like?

Nobody scans a letter when you drop it in a collection box. Its first scan comes when a USPS plant near you cancels and sorts it, usually the evening of the day it was picked up. After that you see a scan at each plant along the way, a scan at the plant that serves the destination, and often one when it is sorted into the order of the carrier's route, usually the night before delivery.

The last event is the day USPS marks the letter delivered. USPS's guide to this data calls it an implied delivery, recorded when the carrier's scanner leaves the area of the address's ZIP+4 on the route, because nobody scans a letter at the mailbox. PigeonTrail shows it as "USPS marked it delivered" and explains what that means. Some letters go quiet before that point, because USPS's own table marks about 17% of ZIP codes as areas where mail is sorted by hand at the last step and no tracking scans are expected. Our guide to what each USPS scan means walks through a real letter from Austin to Columbus.

These scans tell you where a letter is, but they are not a USPS record that you mailed it. In its November 2025 rule on postmarks, USPS said barcode scans "do not constitute evidence of the date when the Postal Service first accepted possession" of a letter. If you need that record, get a Certificate of Mailing at the counter or send it by Certified Mail.

Can the person I mail it to follow the letter?

Yes. Every PigeonTrail letter gets its own tracking page with the route on a map and the day USPS expects it to arrive, and you can share the link or let us send it. When you add the recipient's email, PigeonTrail emails them once at the first USPS scan with the link to that page. If you're on Pro, those emails come from your shop's name instead, and your buyer hears from you when the letter is mailed, when it is almost there and when USPS marks it delivered.

You get your own email at the first scan and again when USPS marks the letter delivered. If a letter falls more than a day behind the date USPS expects, or goes five days without a scan, it is flagged in your letters list, and Pro also emails you about it.

How do I start tracking First Class letters?

1. Make a free account with your email at pigeontrail.com/app, which needs no card.

2. Type or paste an address, or bring orders in from TCGplayer, eBay, Shopify or Mana Pool.

3. Print on the printer you already have, on a #10, #9, #6 3/4, A7 or 6 x 9 envelope, on Avery 5163 labels, or on 4 x 2 or 4 x 6 labels.

4. Put a Forever stamp on it and mail it from any collection box or post office.

5. Watch the scans arrive in your letters list, where the letter shows the day USPS expects it.

Your first 100 letters each month are free. Pro costs $12.99 a month, covers 500 letters and charges 2 cents for each one after that, and Shop costs $49 a month for 2,500. If you'd rather not have a plan, credits cost 10 cents a letter. Your first letter also starts a 30 day Pro trial with no card. The pricing table has every detail.

When should I use Certified Mail instead?

Use Certified Mail when a law, a court, a lease or a contract asks for it, or when you may have to show later that a notice reached someone. It gives you a mailing receipt, a USPS record of delivery and, with a Return Receipt, the signature of the person who took it. A tracked stamped letter gives you none of those records, but it costs far less and suits everyday mail like orders, invoices and cards. Our guide to Certified Mail or a tracked letter compares them in detail.
