A Vehicle Identification Number (VIN) is the string of 17 numbers and letters that an automobile manufacturer assigns to an individual vehicle. The VIN can reveal a number of things about a car, including its airbag type, country of origin, engine size, model year and trim level.
The VIN can be found by looking at the dashboard on the driver's side of the vehicle. The easiest way to view it is to stand outside the vehicle on the driver's side and look at the corner of the dashboard where it meets the windshield. If the VIN cannot be found there, open the driver's side door and look at the door post (where the door latches when it is closed). It is likely that the VIN will also be displayed in this location.
