Zipcode validation

Hi All,

How to validate Zip/Postal code enterd is valid based on country selected? Is there any plugin for checking zipcode format for different countries..

Thanks

I dont know on country level, but on US you can check this gem http://rubygems.org/gems/zip-code-info

Depends on what you want the postcode for. If it's for something like geocoding, you might be better off relying on the geocoder to validate the input.

There's some stuff about this, but the validation is ultimately country-specific (and can change - apparently Ireland is debating the creation of a postcode system):

- https://github.com/globaldev/going_postal - validates postcodes for UK, US, Canada, Australia, New Zealand, and South Africa - Regexp::Common::zip - provide regexes for postal codes. - metacpan.org - not directly applicable, but this is a Perl module with regexes for more countries. The syntax should translate readily to Ruby

Hope this helps!
