Vehicle Identification Number

The Vehicle Identification Number (VIN) Derivative is located in two places on the engine and is a nine digit number stamped or laser etched onto the block at the vehicle assembly plant. If reading the identification number the following information can be obtained

  1. The first digit identifies the vehicle division.
  2. The second digit is the model year.
  3. The third digit identifies the assembly plant.
  4. The fourth through ninth digits are the last six digits of the Vehicle Identification Number (VIN).
