Definitely a FPN, I just assumed it was a traffic warden, but it could've been a police officer who issued it me.

Hi Everyone I received a fixed penalty notice yesterday, and when I went online to pay the fine last night, the system said my Notice Number was invalid. I then tried paying over the phone with an automated system, but again it said my Notice Number was incorrect. I have today telephoned the ticket office to find out what I was doing wrong when entering the Number and I was told that the traffic warden had put an extra zero in the Number when writing my slip out, making the number of digits too many - I was trying to enter a 17 digit number into the system when it would only accept 16 digits. Have I got any grounds for appealing against this ticket on the basis that the information on my ticket is incorrect? Many thanks.
