What term is used for the identification number assigned to vehicles?

The identification number assigned to vehicles is known as the Vehicle Identification Number (VIN). This unique alphanumeric code is crucial for identifying specific vehicles and is used extensively in various aspects such as registration, insurance, and tracking vehicle history. Each VIN is distinctive to a particular vehicle and includes important information about the vehicle's make, model, year, and place of manufacture. The significance of the VIN extends to law enforcement and vehicle history reports, making it an essential component in automotive regulations and law enforcement practices.

Other terms listed, such as License Plate Number and Registration Number, serve different purposes; for example, the license plate number is a registration identifier displayed on the vehicle for legal identification while on the road. The registration number pertains to the vehicle's registration with the state's Department of Motor Vehicles but does not include the comprehensive information encoded in a VIN. Similarly, the term Identification Code could refer to a number used for various identification purposes but does not specifically identify vehicles in the standard context used in automotive law.
