The vehicle identification number (VIN) plate is the legal identifier of the vehicle. The VIN plate is located on the upper LH corner of the instrument panel (IP) and can be seen through the windshield from the outside of the vehicle.
The last five digits of the assembly plant sequential number are stamped onto the rear side of the front sill tie bar. This number is the same as the last five digits on the VIN plate. The VIN plate also has bar code characteristics.
