How to alert on UK NI numbers and credit card details

L0 Member

Hi All,

For credit card numbers there is a default CC# which I can assign a weight to, does anyone know the Palo version of a regex to match UK NI numbers?

This one works in a regex tester but not on the Palo because it doesn't like the formatting of it

^([a-zA-Z]){2}( )?([0-9]){2}( )?([0-9]){2}( )?([0-9]){2}( )?([a-zA-Z]){1}?$

Actually the 1st two digits can't be any letter so it would be better if it only matched the first two digits according to these rules :-

doesn't allow D, F, I, Q, U or V for the first two letters and doesn't allow O for the second letter; on top of this, the prefix letters can not be BG, GB, NK, KN, TN, NT and ZZ. Also the suffix letter is either A, B, C or D, but may be represented by a space if unknown.

I'm hoping someone has done this before and has a working regex I can use!
