Repository of US Addresses ?

[HyltonHaynes]

Is there a repository of addresses in the entire United States available for download, I have been looking for this from couple of week but have no luck in getting any links. Any leads/help is appreciated. 

[HyltonHaynes]

Thanks Chris for those ideas. I did find the repository for Street Suffixes, Prefixes and StreetType from USPS and other sources and corrected those. Street names/numbers is the only one that is giving me a roadblock.

Waiting to hear what ideas the other experts have.

Sure I understand the complexity. I was trying to preprocess millions of addresses, they have a lot of inconsistencies (missing, misspell etc.) because of free form text entry from users. This would then be used for geocoding using ESRI or other tools.

Assuming that Joshua's links can help you out, I'm curious as to what you expect to get in this preprocess phase as opposed to going straight to geocoding. You've got nationwide addresses, which means you have nation wide errors.

I get it that free text entries results in awful addressing;  I worked at a PSAP and was tasked with geocoding about a million records with no standard of entry in any way shape or form.  There was a city that only had three letters, and it was spelled several different ways!  Another city had 48 different spellings!  And this was just one county worth of addresses...

yeah this is the exact problem I'm running into, there can be 'n' permutation combination ways of writing one string. I'm assuming it would be good to do something like fuzzy matching with a repository to correct he addresses and then pass them through geocoding to improve on matches rather than directly geocoding and then choosing right matches.

Best of luck to you.  Keep us posted; you've got quite a challenge ahead!

Not everything, but a really lot of addresses:

If I missed a similar answer forgive me.

1: most addressing is done on the local level. Most of that data is derived from developers for the road names and then the addressing is up to the addressing side (typically in the Plan. Zone Depts.) .

That information is then pushed upward ON REQUEST to third party vendors. Some areas have restrictions, others don't on pushing that data. But given that it is public record in the US the data can usually be had, but the errors spoken of are part of the beast in general.

2: This concept has been banted around for the better part of 50+ years with no real solution, mostly because most places do not have a mandate nor the general ability to do so.

3: As to the privacy issue.

In the US, the information is considered public information and is open to anyone.

Within the realm of the NG 911 systems the short answer is Yes, but due to other issues making that data freely available will not happen in my opinion due to legal issues - and I am sure there are other issues and legal constraints for release / disclosure of that information.
