what does it mean when your VIN doesn't exist?

I am trying to donate a car and they asked for the VIN, which I gave them. However it doesn't come up. I ran a carfax report. No such VIN. I go out to the car thinking maybe the DMV screwed up and put the wrong number on the title, but there it was, right in front of the engine. The same VIN thats on the title.
