Ye Ol' Dublin Town

[Providence1]

So I just found out that Dubliners have one digit zip codes! (must not be many of them in the city proper).

My postal code lookup returns several thousand hits so I could either do something different based on how many characters, or lack or characters, the user enters or I can see if someone has come up with some really cool idea for zip codes with a limited length (and maybe even UK and Canadian zip codes with spaces, etc).

Any ideas?

Thanks in advance for any suggestions...!

You can use regular expressions I guess...
