All motorized vehicles, including Yamaha ATVs, have a unique 17-character vehicle identification number. Yamaha ATV VIN plates, mounted on the frame, may be positioned behind the left wheel well, on the front of the ATV or on the left side beneath the shifter pedal, depending on the model.
Depending on exact positioning, Yamaha ATV VIN plates may be obscured by the fender, skid plate or added accessories, such as nerf bars. A VIN's combination of letters and numbers indicates the manufacturer identification code, vehicle attributes, a check digit, model year, plant identification code and a sequential number. As of 2014, there are numerous smartphone applications that scan VIN plates and send the information to VIN decoding tools on specifically designated websites.
