Locate the VIN beneath the windshield of the car on the driver's side. If you cannot read the VIN from this location, you can refer to the Certificate of Title and Registration or the label on the door pillar of the driver's side, which also contains the VIN.
Verify that the second character of the vehicle's VIN is "F," which is representative of a portion of the World Manufacturer Identification number assigned to Ford vehicles by the International Organization for Standardization (ISO). The third digit provides additional information on the type of vehicle. For example, a Ford truck will be "FT" and a multipurpose vehicle such as an Explorer will be "FM."
