I code stuff with my bare hands.

I like to make programs and devices smarter, and easier to use. I experiment with new, brilliant interface concepts. I'm a programmer, designer, web developer, and a nice guy.

I believe choices make us who are, and are a major part of how we and others feel.

I'm an address validator.

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.)

comment What are the most detailed and reliable address databases for the United States?
@GeoDave Ah. Yes, it is. Notice that the address validates. It's also in the autocomplete, but you don't see it once you type "Dr" followed by the city name because it is a "St" in Lenoir, not a "Dr". Autocomplete does not override what you type in while it gives suggestions, since you know your address better than it does: but validating the address will resolve any discrepancies. That's the difference between suggestion and validation (in our book).

@GeoDave What do you mean by address suggestion exactly? I bet there are at least a couple.

Try this answer, maybe? (Works only for US addresses but you might try a similar approach for different countries.)

comment Samples of US Residential or business addresses without zip+4?
Even unique ZIP codes, like 12345, have addresses with a +4 code of "0001" by default.

revised Using multiple address locators in ArcGIS
The tag "address" is very generic. I replaced it with a more specific one.
