How to Decode a VIN, Character by Character
You can read a surprising amount of a VIN with no tools at all. Here's what each of the 17 positions means, with the country table and the check-digit math fraud investigators use.
Positions 1–3: World Manufacturer Identifier
The first character is the country, the second the manufacturer, the third the vehicle type or division. Common first characters:
| 1st character | Country of manufacture |
|---|---|
| 1, 4, 5 | United States |
| 2 | Canada |
| 3 | Mexico |
| J | Japan |
| K | South Korea |
| L | China |
| S | United Kingdom |
| V | France / Spain |
| W | Germany |
| Y | Sweden / Finland |
| Z | Italy |
| 9 | Brazil |
Familiar full WMIs include 1HG (Honda USA), 1FT (Ford trucks USA), WBA (BMW Germany), JTD (Toyota Japan), and 5YJ (Tesla USA).
Positions 4–8: vehicle attributes
Each manufacturer encodes model, body style, restraint system, and engine here using its own scheme — which is why full decoding needs a database. The free decoder resolves these against NHTSA's records.
Position 9: the check digit
Every character is assigned a numeric value and a positional weight; the products are summed and divided by 11. The remainder (with 10 written as X) must equal the 9th character. A VIN that fails this test is invalid — a re-stamp, a typo, or fraud. Our decoder validates it automatically, and it's a key test in spotting cloned VINs.
Position 10: model year
A single letter or digit on a 30-year cycle. Full lookup table on the VIN year chart.
Position 11: assembly plant
The factory code, assigned per manufacturer. Enthusiasts use it to identify desirable plants for specific models.
Positions 12–17: serial number
The unique production sequence. Low serial numbers on first-year models can carry collector value.
