Typically when you have an address field on a page, you see Country, Province / State, Address Line 1, Address Line 2, Postal Code.

I'm trying to go more granular for the purpose of data mining to offer better intelligence on client's data, but it feels like I have redundant fields, don't know which one of them are redundant and which are absolutely required.

Country (required)

Province / Sate (required)

City (not everyone lives in a city, so is it needed?)

Suburb (only applicable if you live just outside a city)

Town (only seems applicable if you're not close to a city)

Street Address (required)

Postal Code (required)

If I combine Suburb and City, then I'll get people filling in both in some cases or nothing at all filling in their suburb in the Town section.

Wondering if there's some address-field naming convention that's standard and understood by the majority of people on which I can implement auto-complete.
