The VIN number of the older Mondeo is located on the lower black trim strip near the driver's side of the front windshield. Vehicle Identification Number: The Vehicle Identification Number (VIN), or chassis number, is a unique set of seventeen letters or numbers used on automobiles to identify the manufacturer, engine, chassis serial number, and other specifications. Introduction to VIN: Each character in the VIN generally has a specific meaning, and the entire VIN consists of multiple sections. The first section identifies the vehicle manufacturer, comprising the first three digits: the first digit indicates the country/region of origin. If the car is assembled from parts produced in different countries/regions, this digit represents the assembly country/region; the second digit identifies the vehicle manufacturer. In the United States, the Society of Automotive Engineers is responsible for issuing manufacturer codes. The third digit identifies the manufacturer's internal division or general vehicle type.
