> The order of entering an address is street address, city, state, zip code.

In the US. Most of Europe uses street address; postcode, settlement and optionally province; country. There are still enough occasional warts that you shouldn’t dictate the structre of the second line, though: e.g. in France you’ll usually see things like “75005 Paris” but large institutions that get separate deliveries may list addresses like “75231 Paris CEDEX 05”, where everything but “Paris” is a postcode-like routing instruction. Unless you definitely, absolutely know better, just let people type in whatever postal label they want.
