VIN Decoder
Decode any Vehicle Identification Number instantly. The tool validates the 17-character format and the ISO 3779 check digit, extracts the model year, region and country of manufacture, and identifies the manufacturer from the WMI prefix — all locally in your browser. For vehicles sold in North America you can additionally fetch full factory specifications (make, model, engine, body style, assembly plant) from the free public NHTSA vPIC database with one click.
Before you start: this tool makes a network request
The structural decode always stays local. Only the optional “Get full specs” button sends the VIN you entered to vpic.nhtsa.dot.gov, the US government's free public vehicle database — nothing is sent until you click it.

Frequently asked questions
- What is a VIN?
- A Vehicle Identification Number is the unique 17-character serial number assigned to every road vehicle since 1981. It encodes the manufacturer (positions 1–3), vehicle attributes (4–8), a check digit (9), model year (10), assembly plant (11), and the production serial number (12–17).
- Why does my VIN fail the check digit?
- The position-9 check digit is mandatory only for vehicles sold in North America. Many European and Asian market vehicles use that position for other data, so a mismatch there is normal. For a US or Canadian car, a mismatch usually means a typo.
- Why doesn't a VIN contain the letters I, O, or Q?
- They are banned by the ISO standard because they are too easy to confuse with the digits 1 and 0 — a safeguard against transcription errors on titles and registrations.
- Is my VIN sent anywhere?
- The structural decode runs entirely in your browser. Only if you click “Get full specs” is the VIN sent — directly from your browser to vPIC, the free public database of the US National Highway Traffic Safety Administration.
- Can I get the accident or ownership history from a VIN?
- No. The VIN itself only encodes factory data. Accident, mileage, and ownership history live in commercial databases (Carfax, AutoCheck) and national registries, which require paid access.
