What our free VIN decoder gives you
Enter a 17-character VIN and the free preview confirms the year, make and model the VIN belongs to. The decode comes from NHTSA's vPIC database, which holds data reported by manufacturers. In the same step we search our history sources and show how many auction and damage, listing and sales records exist for that VIN. No account and no payment are needed.
That combination is the useful part. A plain decoder tells you what the car should be. The record counts tell you whether there is history worth reading before you go and see it. A 2019 sedan with four auction records is a different conversation from one with none.
The full report ($9.99) adds the detailed decode, including trim, engine, drivetrain, fuel type, dimensions, safety features and manufacturing details, plus the salvage title check, theft check, auction records with photos when available, sales and listing history, NHTSA recall campaigns for the model and market value.
How a 17-character VIN is built
Since model year 1981, every car and light truck sold in the U.S. and Canada has a 17-character VIN in a standard format. The letters I, O and Q are never used, so they cannot be confused with 1 and 0.
| Position | Section | What it tells you |
|---|---|---|
| 1–3 | World manufacturer identifier (WMI) | Country or region and manufacturer. VINs starting with 1, 4 or 5 were built in the U.S., 2 in Canada, 3 in Mexico. |
| 4–8 | Vehicle descriptor section | Model, body style, engine, restraint system and similar attributes, coded differently by each manufacturer |
| 9 | Check digit | A calculated digit that catches typos and many fake VINs |
| 10 | Model year | A letter or number for the model year, for example L = 2020, M = 2021, N = 2022 |
| 11 | Plant code | The assembly plant |
| 12–17 | Serial number | The production sequence number of that vehicle |
Our guide to what all 17 characters mean goes through each position with examples.
How to use a decode before you buy
- Match the VIN in three places: the dashboard plate visible through the windshield, the label in the driver's door jamb and the title or registration.
- Compare the decode with the ad. If the listing says "V6 AWD Limited" and the VIN decodes to a base four-cylinder front-wheel-drive model, ask why. Mismatches are common in scams and in honest mistakes alike.
- Look at the record counts. Zero records is not proof of a clean past, but several auction or damage records mean you should read the full history before making an offer.
- Check open recalls on NHTSA's free VIN lookup and ask whether they were repaired. See our recall check guide.
Official free decoder and other options
NHTSA's vPIC decoder (vpic.nhtsa.dot.gov/decoder) is the official U.S. source. It is free to use, shows the full set of manufacturer-reported attributes such as body class, engine and plant, and does not decode pre-1981 VINs. If all you need is a detailed specification list, it is an excellent choice. Use our decoder when you also want to know whether the VIN has auction, listing or sales history, with the option of a full report.
