What is a VIN?
A Vehicle Identification Number (VIN) is a unique 17-character code assigned to every motor vehicle. It acts as the vehicle's fingerprint, as no two vehicles have the same VIN.
Where to find your VIN:
- Dashboard (driver's side, visible through windshield)
- Driver's side door jamb
- Vehicle registration or title
- Insurance card
VIN Breakdown:
- Characters 1-3: World Manufacturer Identifier
- Characters 4-8: Vehicle Descriptor Section

- Character 10: Model Year
- Character 11: Assembly Plant
- Characters 12-17: Production Sequence

Model year & plant
The model year (character 10) and the assembly plant (character 11) decoded straight from the identifier.

Frequently asked questions
Is this VIN decoder really free?
Yes. The VIN decoder is completely free with no signup, no credit card and no daily limit. Paste a 17-character VIN and get an instant report. If you want the same data programmatically, it's also available through our REST API.
Where do I find my VIN?
Look at the lower corner of the windshield on the driver's side, the driver-side door jamb sticker, your vehicle registration, title or insurance card. The VIN is always exactly 17 characters and never uses the letters I, O or Q.
What does a VIN lookup tell me?
A VIN check decodes the make, model, model year, engine, body style, drivetrain, fuel type and the manufacturing plant. It describes the vehicle as it was built — it is not an ownership, title or accident-history report.
Where does the VIN data come from?
Decoding uses the NHTSA vPIC database, the authoritative US government source for VIN data. That means it works for virtually any vehicle sold in the United States, across all makes and model years.
Why won't my VIN decode?
The most common reason is a typo — VINs are 17 characters and exclude I, O and Q to avoid confusion with 1 and 0. Double-check each character. Vehicles older than 1981 may use shorter, non-standard VINs that don't fully decode.
Can I find tire sizes from my VIN?
Yes. When a decoded VIN matches a vehicle in our database, we show the OEM and alternate tire fitments alongside the report. You can also jump to the Tire Finder for fitment by make, model and year.
