How to read a Mazda VIN
Take a 2019 Mazda3. Its VIN starts JM0BP, and those five characters are the useful part. The rest is unique to one car, so it's painted out here.
Mazda3 (BP) · windscreen VIN tag
- Characters 1 to 3: Maker and country
- Characters 4 and 5: Model and generation
- Characters 6 to 8: Variant
- Character 9: Not a check digit on a Mazda
- Character 10: Not the model year on a Mazda
- Characters 11 to 17: Plant and serial number
Characters 1 to 5
Maker, country, model and generation. Enough to tell a BP Mazda3 from a BM.
Characters 9 and 10
On a US car, a check digit and the model year. On a Mazda, neither.
Characters 11 to 17
Plant and serial number. Unique to one car, so never shown.
The year is on the build plate, not in the VIN
US decoders read the 10th character as the model year. In September 2026 we checked 15,834 Mazdas against their build dates. Even allowing a year either way, it matched about one time in ten, no better than guessing. The build date is on the build plate, and in every Carify VIN check.
