VIN Number

General Information

The VIN (Vehicle Identification Number) is located on the dashboard, facing outward. You can look at it from the outside of the windshield, at the bottom on the driver's side.

There are a couple of VIN decoders on the net which will decode your VIN for you. These are listed below, or continue on to the section on decoding your own VIN.

Decoding the VIN

Your Average Fiero VIN looks something like this: 1G2PF379XGP233123

This is how the VIN is decoded:

Position 01: Country of Origin (1=USA)
Position 02: Company (G=GM)
Position 03: Division (2=Pontiac)
Position 04:
1984: Manual or Automatic seatbelts. (A=Manual)
1985-1988: Model (P=Fiero)
Position 05: Model (E=coupe, F=SE, G=GT, M=Sport Coupe)
Position 06-07: Bodystyle (37=Notchback Special, 97=Fastback, 11=Notchback. There is no known difference between 11 and 37.)
Position 08: Engine (9=L44 2.8L V6, R=LR8 2.5L L4)
Position 09: Check digit (see MVSS115 Section 5)
Position 10: Model year (E=84, F=85, G=86, H=87, J=88.)
Position 11: Built at Plant (P=Pontiac, MI plant)
Position 12-17: Plant sequence number. (Drop the leading "2" for XX,XXXth car made in the model year.)

I noticed a thread a while back on VIN numbers. I ran across this document and figured it might be usefull to someone. Sorry about the date, but I think you can use this if your VIN isn't over 17 chars.

S5. Check Digit.

S5.1 A check digit shall be provided with each vehicle identification number. The check digit shall immediately follow the fifth character of the second section and appear with the vehicle and on any transfer documents containing the vehicle identification number and prepared by the manufacturer to be given to the first owner for purposes other than resale.

S5.2 The check digit is determined by carrying out the mathematical computation specified in S5.2.1-S5.2.4.

S5.2.1 Assign to each number in the vehicle identification number its actual mathematical value and assign to each letter the value specified for it in Table IV.

S5.2.2 Multiply the assigned value for each character in the vehicle identification number by the weight factor specified for it in Table V. Multiply the check digit by 0. Add the resulting products and divide the total by 11.

S5.2.4 The remainder is the check digit. If the remainder is 10, the check digit is X.
