Mailing Address Verification, Etc. Get County from Zip

Question

It seems fairly common today for websites to perform some address verification behind the scenes. For example, the 4 digit extension on zip codes is commonly filled in. In addition to filling in the 4 digit zip code extension, I would like to know what county the address belongs to.

This will be utilized in an ASP.NET 3.5 application that already has all the hooks in place for ASP.NET AJAX along with jQuery.

What services out there would allow for this to be done? Web services, 3rd party includes, etc.

This is old, but if it can help someone, then my time was well spent. It sounds like what you are looking for can be accomplished in two ways.

1 - If you just want to append the county, based on the address, you can do this with a simple ZIP Code/County database.

2 - If you want to standardize the address, verify it, and then add the county to it, you'll need a service that provides frequently updated USPS data. This is part of our standard address verification API called LiveAddress. LiveAddress

I work for an address verification company called qualifiedaddress.

If you've got cash, NetAddress is built for .NET.

It's also been asked on SO before: here.

NetAddress doesn't appear to include county (I still haven't found one that includes county). – James Manning Apr 09 '10 at 13:28

There are many services. We perform our shipping through FedEx so we use their "Address Validation Service". The wrapper code to their API in python can be found here. The manual from FedEx can fe found here.

The are others like minfraud. You can pass fields such as shipping and billing address, phone numbers, emails, ip address, etc.. See more here. Based on the provided information, you will get a response that looks like this:

MinFraud AVS check is more geared towards figuring out if a customer that is conducting business on your site is trustworthy.

The US Postal Service's website lists many address verification services.Publication 28 (PDF) is the addressing standard for US addresses. Unfortunately, it's more complicated than your schema.

Depending on the license option you need UPS can be free.

Note that the UPS Address Validation API limits usage to only those applications which intend to deliver packages through UPS. Although free, it can't be used solely to clean an address during data entry. – NotMe Oct 29 '10 at 14:55
