I really think that you're going to have to come up with a regex for each country -- some of them could be re-used, but that weirdness of UK postcodes is going to force you to develop your own system for them.

You could, for example, have a hash of regexes, and use the first column as the key. $regexes{'GB'} would be the one that dealt with your SW1 example, and it would be something like /\w+(\d+)(\w)?\s\w+(\d+)/ and test the values in $1 and $3.

But in fact, come to think of it, you'd need at least two for the UK because as you can see, London postcodes have a different format to ones outside London.

I wonder whether the UK postal authorities have some kind of database or flat-text file you could grab and munge.
