This is the only zip code and area code solution you will ever need! AreaZipCode.net provides developers with a feature rich SDK written in C# .net. It provides developers with methods to return location data from a wide range of values including zip code, area code, radius, city, and state. Flexible Provider Architecture The API uses provider architecture so that you can specify XML file, web service, or SQL server data access strategies for retrieving data. You can choose to host the data in your sql database, in a local cached and pooled XML file, or call our web services layer directly using HTTP SOAP, POST, or GET. We give you the ability to pass the data directly to your existing location based search stored procedure or SQL statement, with no impact to your existing application. Low Maintenance Updating your location data can cost you time and money. Turn on the automatic update feature and get the most recent location data, on the interval you specify or call our web services directly for a hands-off solution. Great Performance Use the .net API with SQL server for super high speed queries. Tables are indexed for optimal performance. Use in memory representations of the data for near real-time queries. Easy Deployment Stay up to day with automatic updates. Set the interval and never touch it again! If you're deploying your solution as a standalone windows application, don't worry, just copy the dll into your solution and let the data load from raw XML. That means the database is optional! If you are using a database, the product includes a simple configuration windows application. Scaleable Scale up and scale out! With the web services based architecture; you have the ability to span regions and software boundaries. Availability If you need a solution that can fail over when the web services layer is unavailable, this is it. You just set the provider type when your connection is unavailable and all data is retrieved from your local cached copy. Just one line of code! Extensible The self contained .net based API provides the ability to extend the application and the data beyond its existing implementation. Full documentation makes developing more features easy.
