if you call 131171 and use the prompts to check a vehicle....all you need to do is say the reg number and the recorded voice at the other end will tell you the VIN,engine number,date of reg expiry and if it been through the VIV system ect.......its a 24 hour system so you can do it anytime.....just give them the reg and it will sing like elvis giving anyone the details of your vehicle,i actually think its a breach privacy myself and shouldnt be allowed.....imagine the amount of false-e-fying you could do and shit you could get innocent ppl in
