A VIN (Vehicle Identification Number) is the 17-character code a manufacturer assigns to a vehicle. It uses letters and digits but never I, O or Q, so those characters cannot be confused with 1 and 0.

Look on the driver-side door jamb, at the bottom of the windshield on the driver side, or on the title, registration and insurance card.

Yes. There is no account, no payment and no usage limit.

No, and the page says so. Ten makes get a full decode (year, make, model, engine and plant): Toyota, Volkswagen, Ford, Hyundai, Honda, Kia, Nissan, Chevrolet, BMW and Mercedes-Benz. Ten more get year, make and plant plus model and engine when the public data covers them: Subaru, Mazda, Lexus, Audi, Tesla, Jeep, Ram, GMC, Dodge and Volvo. Every other make shows the year, make, plant code and country only.

No. This decoder accepts the 17-character VIN used from 1981 onward. Older or shorter numbers return a length error instead of a guess.

No. Decoding runs entirely in your browser, and nothing is written to cookies or browser storage. If you share a result, the link you create contains the VIN in its address — that only happens when you choose to share.

The 10th character is the model-year code. The position breakdown on this page shows the code and the year it maps to, including the 1980–2009 and 2010–2039 windows.

The public NHTSA vPIC data does not cover that field for the VIN. The decoder names the gap instead of guessing, so “Not decoded” means the source data is missing, not that the VIN is invalid.
