Common Mazda WMI prefixes (VIN positions 1–3)
| WMI prefix | What it identifies |
|---|---|
| JM1 | Mazda passenger car, built in Japan |
| JM3 | Mazda SUV/MPV, built in Japan |
| 3MZ / 3MV | Mazda, built in Mexico (Salamanca) |
| 4F2 / 4F4 | Mazda, built in the USA |
How a Mazda VIN breaks down
Every Mazda built since 1981 carries a 17-character VIN under the ISO 3779 standard. Positions 1–3 are the World Manufacturer Identifier — a Japan-built Mazda car commonly opens JM1, a Japan-built SUV JM3, and a Mexico-built model 3MZ or 3MV. Positions 4–8 encode the model line, body and engine; position 9 is the check digit; position 10 the model year; position 11 the plant; and 12–17 the sequential build number.
Because the engine and trim are described in positions 4–8, two same-year CX-5 or Mazda3 models can carry different descriptor characters depending on Skyactiv engine and drivetrain.
Decode vs. history: what the VIN can and can't tell you
Decoding a Mazda VIN reveals the factory build — year, engine, plant and trim. It won't show what happened after the sale. For salvage, accident, flood and odometer brands, run the same VIN through a history report drawing on NMVTIS and state-DMV records.
