A VIN (Vehicle Identification Number) is a unique 17-digit code assigned to every vehicle produced since 1981. The VIN serves as the vehicle's fingerprint, providing a standardized way to identify and track a particular vehicle throughout its lifespan.

The VIN is typically found in several locations on the vehicle, including the dashboard, engine block, and door frame. The VIN can be used to obtain information about the vehicle, such as its manufacturer, model, year of production, engine size, transmission type, and country of origin. It is often used by government agencies, insurance companies, and law enforcement to track vehicle history, verify ownership, and investigate accidents or thefts.
