How to read a 17-character VIN
A VIN identifies the vehicle; its positions describe different parts of that identity. The manufacturer determines many of the detailed codes, so a generic character chart cannot replace manufacturer data. Model-year codes repeat, which is why the tool accepts a known model year.
- Positions 1–3
- Manufacturer identifier. Some low-volume manufacturers also use later positions.
- Positions 4–8
- Vehicle attributes encoded by the manufacturer.
- Position 9
- Check digit used to detect many transcription errors.
- Position 10
- Model-year code; the code repeats across decades.
- Position 11
- Assembly plant code.
- Positions 12–17
- Vehicle identifier / production sequence, with manufacturer-specific details.
VIN decoder, history report or recall check?
Choose the check that answers your question. This free decoder returns vehicle specifications. It does not establish ownership, reveal every installed option or produce a vehicle-history report.
For a used-car purchase, compare the dashboard and door-label VINs with the title, have the vehicle inspected, and use the appropriate title and recall sources. A correct decode does not establish that the physical vehicle is safe or free of liens.
- Year, make, model and reported engine
- Use the decoder, then compare the result with the vehicle.
- Unrepaired safety recalls
- Use the official NHTSA VIN-specific recall lookup linked in the results.
- Title brands, liens and ownership
- Use state title records and appropriate history services.
- Classic or pre-1981 VIN
- Use make- and year-specific records. Classic mode supplies structural guidance.
What to do with missing or conflicting specifications
“Not reported” means NHTSA did not supply that field. Confirm trim, safety equipment, modifications and optional packages using the vehicle, original window sticker or manufacturer.
If the federal service is temporarily unavailable, local character and check-digit checks remain available. Retry the lookup later or open NHTSA directly. Do not use a guessed correction in a title or insurance application.
