Datatag is not a black market source. The process involves your local law enforcement agency. I don't think the law is in the black market and is going to help you commit fraud.
I know someone that got a VIN from Datatags, he was correcting a fast one the seller tried to pull on him, he put the correct VIN back on the car. The prior owner swapped the dash frame to another because the car was missing it's original engine and the donor had the original engine, what the donkey neglected to do was remove the factory fender tag which had the original VIN on it and those numbers matched the build plant and partial stamped on the body in 2 places .
There was no law enforcement involved. Maybe things have changed ?
