Foreign / International Addresses

[stndrdsnz]

I have an application that I developed as a contact management system. The original development of the application was written to store domestic (US) addresses and validate them.

However, recently some of the users of the system are needing to be able to store Foreign addresses in the system, but are unable to as a result of some of the data validation erring out a foreign address (mainly zipcode and phone).

Do any of you have good solutions for storing addresses, both foreign and domestic? Or know of an open source application that does, so that I could look and see how they manage that data?

Thanks

I believe the US Postal Service has a guide of some kind I've read before on properly formed addresses both within and outside of the US. I found it with google last time I needed it fairly easily.
