Individuals and dealers who sell cars get lots of questions from potential buyers. Buyers want to know a vehicle's maintenance history, mileage, and optional features, and some buyers want to know the Vehicle Identification Number, or VIN. The VIN is a 17-digit serial number for all cars sold in the United States since model year 1981.
A VIN number is unique to each car. It identifies the make, model and year the car was made. The VIN number also tells where the car was built, and what engine and transmission were installed. VIN number plates are installed on the dashboard visible from outside the car and on the driver's door jamb. Some manufacturers put VIN numbers on engines and transmissions, as well.
Because the VIN number will always be connected to an individual vehicle, VINs are used by almost every organization that deals with motor vehicles. Law enforcement agencies track stolen cars by the VIN number. Insurance companies and state motor vehicle departments use VIN numbers to identify cars. The manufacturer keeps track of service and recalls through VIN numbers.
With a VIN number, a potential buyer can investigate the history of a car he would like to purchase. There are services that will show if a vehicle has been in an accident or been reported stolen, how many times the car has been sold, and whether or not it has outstanding recalls. The buyer can also contact the manufacturer to see what engine and transmission the vehicle was originally equipped with to learn if either of these items has been replaced.
Assuming the seller has been forthright in the car listing, there is no risk to the seller in disclosing the VIN. Nearly all eBay Motors listings show the VIN. Many used car dealers offer a VIN report with every car they sell, so that the buyer can feel confident in their purchase. Most buyers will not close a sale with a seller who refuses to disclose the VIN number.
