I am grasping at straws here but for what its worth... There is a vehicle outside my house my that I suspect has been stolen. When I went to https://www.hpicheck.com/ to do a free check, the system tells me that the number is invalid. Does that conclusively mean that the number plate the vehicle is sporting is fake? I tested the system by providing plates of cars parked across the road and the system successfully returned the make of the car. Anyone? Edit: Its a van btw. Does that make a difference?
