Penalty Charge Notice (PCN)
PCNs (previously called parking tickets) are issued when drivers break parking rules or enter a bus lane (external link) during times of the day when restrictions are in operation.
PCNs are also issued when a moving traffic rule (external link) has been broken.
If you receive a PCN, please take note of the reference number. This will start with ZN. You will need to quote this number if you wish to pay or challenge the PCN.
If you have a PCN which begins with the letters HP, you will need to follow separate guidance.
There are postal delays in N4, N8 and N10. If you have received a PCN late or Charge Certificate and are unable to pay the discounted amount, you will need to let us know through our Challenge a PCN page.

Our new improved online parking services
We’ve created a digital self-serve option for PCNs which gives you more information, choice, and greater control over parking arrangements.
If you have a PCN number, starting with ZN, our parking ticket viewer makes it even easier for you to pay or challenge PCNs online, and view or upload supporting evidence.
