After the JN1 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.
JN1 is a Infiniti WMI. Every VIN beginning with JN1 was built by Infiniti and decodes to that make.
The first character J places the manufacturer in Japan (Asia region) under the VIN standard.
No. They are synthetically generated but checksum-valid and use the real JN1 WMI, so a decoder returns Infiniti. No real vehicle's VIN is used.
