How can I validate worldwide postal codes in my .NET code

Question

I am looking for a way to validate worldwide postal codes in my .NET project, and I don't really want to come up and maintain regular expressions for the whole world.

Preferably I would want to pull in a dependency to a library or in the worst case use some web based service (but that would really be a last resort).

Check out PostalCodes.Net package on github.

It support most countries and has a good interface. Here is an example:

var country = CountryFactory.Instance.CreateCountry("PL");
var postalCode = PostalCodeFactory.Instance.CreatePostalCode(country, "44-100");
