Barnet PCN entered wrong reg - appeal rerfused -HELP!! in Local Authority Parking and Traffic Offences Posted October 31, 2016 If it's any help, I did actually get off a parking ticket under similar circumstances ... I was at a hotel and to use the parking you had to enter your REG on some swipe screen thingy. I entered it wrong, only realised it when I got the ticket. In my appealI said the swipe screen wasn't working properly and that it didn't put the characters in. I asked them to give details of any reg numbers entered that were similar to mine, and they seemed to give up and waived the ticket.
