9-digit ZIP Code (ZIP+4) for Finding Representatives & Legislators

If you have a website that lets people lookup U.S. Government legislative districts or find representatives, you've probably been frustrated with finding a good way to get people to get their ZIP+4 Code. Since the +4 Code is pretty much required to find the correct congressional and legislative districts, it's a problem that a lot of webmasters face.

A lot of people end up directing their visitors to find the ZIP+4 Code on the USPS Lookup. This is an OK solution, but it isn't the best solution. It takes the visitor away from your site and is inconvenient.

By using the Qualified Address API, you can implement a better solution. Our Address Verification API can be integrated into any website form in as little as 15 minutes and would allow the visitor to enter their address and get their ZIP+4 right on your website. It's convenient for both you and your user.

Please visit the Address Verification API product page at QualifiedAddress.com for more information on how you can use this on your website to improve your lookups that require ZIP+4 Codes.
