Vehicle Identification Numbers (VINs)

Vehicle Identification Numbers are unique codes given to each on-road vehicle in the United States. From 1981, each new car is given a standardized 17-digit code, which includes a serial number.

Older cars may have VINs too, although they will not follow the standardized formula. A VIN lets you unlock vital information about the vehicle and its history.

Locating VINs

You can find a VIN on the car itself and on a variety of documents.

Finding it on the Car

The two most common places are the dashboard and driver's side door jamb sticker. Other places to find it are on the engine and inside the hood.

Finding it on Paperwork

The VIN is always on vehicle title documents. It's also on insurance policies, service records and police reports for the vehicle.

Do motorcycles or ATVs have VIN numbers?

Yes. You can find them on the frame. The National Highway Traffic Safety Administration requires all motorcycles and all-terrain vehicles (ATVs) or "four wheelers" and "three wheelers" to display this 17-digit unique vehicle identification number on the frame. Check your owner's manual for exact location.

Do bicycles have a VIN?

No. Bikes are not motorized and are not registered with state DMVs. But they should have a manufacturer's serial number which can be used to register a bike with a local municipality or the national bike registry.

Using VINs

Characters within a VIN indicate a vehicle's year, make, model, where it was manufactured, and more.
