After the 1GN 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.
1GN is a Chevrolet WMI. Every VIN beginning with 1GN was built by Chevrolet and decodes to that make.
The first character 1 places the manufacturer in United States (North America region) under the VIN standard.
No. They are synthetically generated but checksum-valid and use the real 1GN WMI, so a decoder returns Chevrolet. No real vehicle's VIN is used.
