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: 
Yes there are tools, free would depend on where your addresses are located.
There are many not free address scrubbers licensed by the USPS. One of the ones I use is [ZP4](http://www.semaphorecorp.com/cgi/zp4.html). I find the input and output to be flexible based on how you store your data currently and how you would like to store your data in the future.
You can choose to output your data, for those addresses which match to deliverable addresses within the USPS data, into 7 fragments. These fragments correspond to house number, predirection, street name, street suffix, postdirection, apartment unit abbreviation, and apartment number. It is the lease expensive solution I have found.
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.)
