The official Vehicle Identification Number (for title and registration purposes) is stamped on a metal tab which is fastened to the instrument panel. It is close to the windshield on the driver's side and is visible from outside the vehicle. In addition to the aforementioned model identification, the Vehicle Identification Number also contains coded information regarding the assembly plant, model year, type of engine, and production sequence number. Beginning with the 1981 model year, the expanded Vehicle Identification Number also includes coding for the type of restraint system, as well as the identity of the vehicle's specific world manufacturer.
The Vehicle Certification Label is affixed to the left front door lock panel or door pillar. The upper half of the label contains the manufacturer's name, month and year of manufacture, Gross Vehicle Weight Rating (GVWR), Gross Axle Weight Rating (GAWR), and the certification statement. The lower half of the label contains the Vehicle Identification Number, as well as coded information regarding the vehicle's color, body type and interior trim, as well as axle ratio and transmission. Additional codes on the lower portion of the label pertain to the vehicle's air conditioning, radio, vinyl roof and sun roof (if applicable). Beginning with the 1981 model year, the Vehicle Certification Label also includes coding for body side moulding, front and rear springs and special order numbers.

The first digit in the vehicle identification number is the model year of the car (9=1979, 0=1980). The second digit is the assembly plant code for the plant in which the vehicle was built. The third and fourth digits are the body serial code designations (2-dr sedan, 4-dr sedan, etc.). The fifth digit is the engine code which identifies the type of engine originally installed in the vehicle (see the Engine Codes chart). The last six digits are the consecutive unit numbers which start at 100,001 for the first car of a model year built in each assembly plant.1981-88
See Figure 3
Beginning in 1981, the serial number contains seventeen digits. The first three give the world manufacturer code. The fourth is the type of restraint system. The fifth will remain the letter P . The sixth and seventh are the car line, series and body type. The eighth is the engine type. The ninth is a check digit. The tenth is a letter representing the model year (B=1981, C=1982, D=1983, E=1984, F=1985, G=1986, H=1987, J=1988). The eleventh is the assembly plant. The remaining numbers are the production sequence.
