While the light-duty and passenger segments encompass a large portion of the vehicles that one might be looking to VIN decode, it certainly doesn't cover them all. These additional segments each represent huge markets with large direct and allied business opportunities. As a result, there is a fair amount of interest in services to VIN decode these vehicles.
