VIN
Vehicle Identification Numbers (VINs) are used to uniquely identify vehicles. Prior to 1980 there was not an accepted standard for these numbers, so different manufacturers used different formats. Modern day VINs consist of 17 characters that do not include the letters I, O or Q. In the United States a confidential vehicle identification number is used with certain major assemblies of a vehicle and is known only to designated persons within the FBI and the National Automobile Theft Bureau.
