Many of them are duplicates, but at the very least I have 31,514 that need to be coded, although that would leave out many that I want to use. I am in the process of developing filters to clean out apartment numbers, etc., to be able to pull a single coordinate for a whole set of addresses, and there are at least 6,000 that are invalid (from the original 146k, so 140k). It is a lot. I will take a look at openaddresses and do some testing. </div>

It seems like a good system, I think I can use it to pull addresses out of my database and write back coordinates. There is one thing that I am not sure, about, though, is whether I am actually allowed to use the Google API without my use being liked to a specific web page. The terms of service and form for getting a Google API key require a URL linked to a Google account. In fact, it looks like the API can only be used through a web site:</p>
