Hi im a beginner to regular expressions really, just learning the basics, at the moment i require to be able to do some basic validation checking on numbers and hoped for some help here.

for example, our council tax ref numbers are in format of 8 numeric characters and begin with a 3 or a 2, such as 31000044 or 28443562.

my form needs to validate these on this basis so could anyone provide a regex that would do this?

thanks

Well, this is a "Newsbin Regular Expression" forum. Not a general purpose one.

Code: Select all

^[23]\d{7}$

should work
