After the 3GN 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.
3GN is a Chevrolet WMI. Every VIN beginning with 3GN was built by Chevrolet and decodes to that make.
The first character 3 places the manufacturer in Mexico (North America region) under the VIN standard.
No. They are synthetically generated but checksum-valid and use the real 3GN WMI, so a decoder returns Chevrolet. No real vehicle's VIN is used.
