Vehicle Identification Number (VIN)

Print

See Figures 1, 2, 3, 4, 5 and 6

The 1964-67 vehicle serial number is stamped on a vehicle identification plate, attached to the left front door hinge pillar. On 1968 and later cars, the Vehicle Identification Number (VIN) is stamped on a plate located on the top left hand side of the instrument panel, so it can be seen by looking through the windshield.

The VIN is a thirteen digit (1968-80) or seventeen digit (1981 and later) sequence of numbers and letters important for ordering parts and for servicing. The VIN is also part of the Federal Vehicle Theft Prevention Standard and cannot be removed or altered in anyway.

Model years appear in the VIN as the last digit of each particular year (6 is 1976, 8 is 1978, etc.) until 1980 (which is A). This is the final year under the thirteen digit code. The seventeen digit VIN begins with 1981 (B) and continues 1982 (C), 1983 (D), etc. Once the vehicle year lettering system began, any letter that might be mistaken for a number was skipped, therefore 1988 was J not I, because I might be mistaken for the number 1.
