VIN this is an acronym for Vehicle Identification Number, a number unique for every single vehicle produced. It serves to not only identify a specific vehicle but also contains coded information relative to such things as the vehicle’s country of origin, manufacturing plant, trim code, drive train, and interior and exterior color just to name a few. This number helps the body shop order the correct replacement parts and the correct paint color for each car. Any professional estimate or repair order will include this number.
