Question: Ok, so with ArcGIS 10, ESRI has depricated 'Address Standardizing' in the new locators, I know you can still use the 9.3.1 locators to do this; but I heavily suspect that after the 10.1 version we will see this available less and less.  

The [FGDC Addressing Standard](http://www.fgdc.gov/standards/projects/FGDC-standards-projects/street-address) places a heavy value on good addresses having the Prefix, Prefix-Direction, Street-Name, Suffix, Suffic-Direction values for a good clean form. And my agency has a need for the same.  

Are there other tools out there that people are using to take structured addresses and parse them out fairly-reliably so they can be stored? Are any of them free?

\**Update:*\*I came across [this on CodePlex (US Address Parser)](http://usaddress.codeplex.com/) and it has given me a really good jumping off point. Its really nice in that its managed code that I can use all over the place and so far it has had a very high sucess rate at breaking down parts to be reviewed line by line and part by part.

Answer: 
I have had great success using the us address parser library. I built a python tool that uses the library to create the parsed out address fields. <https://github.com/datamade/usaddress>
Another option for US based addresses is [YAddress](http://www.yaddress.net). It also corrects and validates the address before splitting it into components. (I work for the company that makes it.)
