After the 3MV WMI, positions 4–8 describe the model, body and engine; position 9 is the mod-11 check digit; position 10 is the model year; position 11 is the assembly plant; and positions 12–17 are the serial number. See the full 17-digit VIN format.
3MV is a Mazda WMI. Every VIN beginning with 3MV was built by Mazda and decodes to that make.
The first character 3 places the manufacturer in Mexico (North America region) under the VIN standard.
