Perfect Address Software Developer's Kit TM (January 2023 data)
Attention Windows Developers - Now you can easily add transparent address matching and ZIP+4 lookup to your own programs. Find the exact county name, county FIPS code and congressional district (117th Congress) for every address!
The Perfect Address Software Developer's Kit makes it easy to add transparent address matching and ZIP+4 lookup to your web site, custom or commercial data entry programs, point of sale programs, customer support applications, or database programs.
The Perfect Address Software Developer's Kit (SDK) consists of a mailing address database for the entire USA plus 32-bit and 64-bit "search engine" DLL modules which searchs the 700-MB national address database quickly and efficiently in a standard Windows 32-bit or 64-bit environment. The search engine is a standard Windows Dynamic Link Library (DLL) module which makes it easy for you to search the address database from your own custom programs, from commercial Windows database applications such as MS Access or Visual Basic, or from commercial Windows spreadsheet programs such as Excel or Quattro Pro.
The Perfect Address SDK does all the dirty work of address matching, correcting spelling and naming mistakes for cities and streets, and adding the correct street name suffix. It even finds the proper city name from only the ZIP code, and corrects "alias" city names to the preferred city name. It also provides additional detailed information about each address, including the exact county name and FIPS code, congressional district, area code, time zone, and daylight saving time status.
And best of all, you can incorporate the Perfect Address SDK into your web site or commercial product. You can even distribute the SDK's DLL modules free of all royalties!
* Semiannual subscription: Annual fee. You'll receive the January 2023 Perfect Address SDK now and a second version in 6 months.
