Hi There, I have created a form where I am asking the user to input a postcode, how do I validate the field to ensure it is a genuine Postcode format for the UK?
I am using NWC
Thanks

Hi,
Because of the amount of combinations that a UK postcode can have this may be a little difficult. I looked at using a Text Mask but that won't work. Cant really see how to impliment a regular expression validation.

Here are some suggestions in stackoverflow but none are comprehensive - including the regex suggested by the UK Government themselves! https://stackoverflow.com/questions/164979/regex-for-matching-uk-postcodes

@AndyEmery looks like this regular expression should do the trick:
^[A-Z]{1,2}[0-9][A-Z0-9]? ?[0-9][A-Z]{2}$
