FedEx Tracking Number Validator
A FedEx tracking number is 12 to 22 digits long. FedEx Express uses 12 digits, Ground uses 15 digits, SmartPost uses 20 digits, and Freight uses 12 digits starting with specific prefixes. The last digit is a check digit using modulo 11.
If you are tracking a FedEx package, you will notice that their tracking numbers are purely numeric, unlike some other carriers that include letter prefixes like "1Z". FedEx uses specific digit lengths to identify the shipping speed and network used to transport your package.
Here is a quick look at the main formats:
| Service / Mail Class | Digit Length | Example |
|---|---|---|
| FedEx Express | 12 digits | 400123456789 |
| FedEx Ground | 15 digits | 961101234567890 |
| FedEx SmartPost (Ground Economy) | 20 digits | 92612999912345678901 |

Guide to common FedEx formats
By simply counting the digits in your tracking number, you can tell exactly how your package is traveling.
12-Digit format (FedEx Express)
Most FedEx Express shipments use a 12-digit numeric code. This service includes premium options like Priority Overnight, Standard Overnight, 2Day, and International Express. Because Express is time-definite, these shipments move through FedEx's air networks and receive frequent scan updates.
15-Digit format (FedEx Ground & Home Delivery)
FedEx Ground and Home Delivery packages use a 15-digit tracking number. This is standard road transport, taking 1 to 7 business days depending on the distance between the sender and the recipient. Unlike Express, Ground packages are scanned at regional sorting terminals rather than airport hubs.
20-Digit format (FedEx SmartPost / Ground Economy)
FedEx Ground Economy (formerly known as SmartPost) uses a 20-digit tracking number. This is a budget service where FedEx handles the long-distance shipping and then hands the package to the local post office (USPS) for the final delivery.
- Once the package is handed over to USPS, you can track it on the USPS website using the exact same 20-digit number.
- Updates on the FedEx website will usually stop after the scan indicating the package was transferred to the local post office.
22-Digit format (FedEx Freight)
Large freight, palletized shipments, and LTL (Less-Than-Truckload) shipments use a 22-digit numeric code. Because freight moves on cargo trucks between commercial logistics terminals, tracking updates are less frequent than for standard home deliveries.
Decoding the barcodes
Internally, FedEx uses the PDF417 barcode format on their shipping labels. FedEx introduced the standard 12-digit Express tracking code layout in the late 1980s alongside their SuperTracker barcode scanning system, while Ground adopted the 15-digit structure in the early 2000s following the acquisition of RPS (Roadway Package System).
These barcodes contain structured data:
- For Express (12 digits), the number is a sequential serial code with a check digit using the Modulo 11 algorithm. The first 11 digits are multiplied by a repeating sequence of weights (1, 3, 7, 1, 3, 7...), summed, and divided by 11 to determine the checksum.
- For Ground (15 digits), the number contains a mailer ID and a unique package sequence, verified with a Modulo 10 checksum.
Troubleshooting common tracking errors
If your tracking number is showing an error on the website, it is usually caused by one of these issues:
Label created but not shipped
If the tracking page says "Shipment information sent to FedEx," the merchant has printed the label but has not dropped the package off or scheduled a pickup. Give it 24 hours to receive its first active scan at a FedEx facility.
Hidden characters in copy-paste
When copying tracking numbers from confirmation emails, make sure you do not include spaces, dashes, or brackets. A formatted number like 1234-5678-9012 will return a "not found" error. Remove all non-numeric characters before searching.
Wrong carrier website
If you paste a 15-digit FedEx Ground number into a USPS or UPS tracking search, it will return an invalid error. Ensure you are tracking the package on the official FedEx portal.
FAQs
Can I track a FedEx package without a tracking number?
Yes. If you sign up for the free FedEx Delivery Manager service, you can view all incoming packages sent to your name and address without entering individual tracking numbers. You can also track shipments using reference numbers (like purchase order numbers or invoice IDs) if the shipper entered them when creating the label.
Why is my package sitting in another state?
FedEx routes packages through regional hubs (such as their main air hub in Memphis, Tennessee). Even if a package is traveling between two cities in the same region, it may fly to a hub in another state first for sorting. This is normal routing and does not mean your package is lost.
What should I do if my package is marked "Delivered" but is missing?
Check all entry points around your home, including side doors, porches, and garages. If you live in an apartment, check with the front desk or mail room. If you still cannot locate it, contact FedEx customer support immediately to request a delivery verification check (drivers often take photos or log GPS coordinates at the delivery spot).
How long does tracking history remain active?
FedEx keeps tracking information active in their system for 90 days after delivery for Express and Ground packages. Freight records are maintained for up to two years.
