comment How often does Google change the geo-coordinates for a given address?
Even if we knew how often Google updates their map data, I think the real question is, "Can I use coordinates as a way to identify addresses/buildings?" unless I'm reading the question wrong?

comment Is there a geocoding service that can return building or area type?
Any services which offer RDI can tell you if an address is residential or commercial, at least (for example, SmartyStreets, where I work). Doesn't tell you what kind of district but it can tell you if it's a "high-rise" (meaning, has secondary units, like an apartment or office building).

comment Commercial Geocoding API that is as good as Google
See this answer for a link to a document comparing 11 different geocoding services. Note: This might have been compiled before SmartyStreets improved their geocoding accuracy.

comment Possible for there to be same street, city, and country in two locations
What about something like "Main St" and "Main Rd"? Are you referring to just the street name or also its suffix?

comment What is the best way to apply the correct ZIP Code when Geocoding
This is a good answer because it addresses the fact that ZIP codes are not polygons.

comment Looking for an API that will autocomplete adresses, and split them up into parts
For US addresses, you could try SmartyStreets... (I helped develop the autocomplete API. It comes free with an active subscription.)
