The Vehicle Identification Number (VIN) is a seventeen digit alpha/numeric sequence stamped on a plate which is located at the top, left hand side of the instrument panel.
As far as the car owner is concerned, many of the digits in the VIN are of little or no value. At certain times, it may be necessary to refer to the VIN to interpret certain information, such as when ordering replacement parts or determining if your vehicle is involved in a factory service campaign (recall). In either of these instances, the following information may be helpful:
Fig. Fig. 1: The VIN tag is located on the dash, behind the windshield, in the upper left hand corner

1ST DIGIT - Indicate the country of manufacture. A
designates the USA;
8TH DIGIT - Indicates the type and the manufacturer of the original engine which was installed in the vehicle.
10TH DIGIT - Indicates the model year of the vehicle.
designates a 1982 model,
is for 1983, and so on. Certain letters such as I, O and Q are not used due to possible confusion with numbers.
11TH DIGIT - Indicates the specific plant at which the vehicle was assembled.
12TH-17TH DIGITS - This is the plant sequential number, which identifies the specific number of each vehicle within a production run. In the event of engineering change or a recall involving only a certain quantity of vehicles within a production run, the affected vehicles can be identified with this number.
The Vehicle Emission Control Information (VECI) tag is located on the front of the strut tower on most vehicles. This tag identifies the information needed to tune-up your vehicle.
