Paying or challenging a parking fine
You must pay or challenge a parking fine, also known as a Parking Penalty Charge Notice (PCN), within 28 days of it being issued.
Your fine will be reduced if you pay within 14 days.
You'll need your vehicle registration number and the 10-digit reference number printed on your PCN in order to pay or challenge a fine. The reference starts with two letters followed by 8 numbers, or 7 numbers if the PCN ends in A.
