ZP4 Address Correction Snapshot

ZP4 supports program-to-program interfaces so your standard database or custom applications can automatically correct addresses. Any program can accept an address typed in by a user, then pass the address to ZP4. ZP4 will immediately correct and standardize the address and pass it back to the program. In the example below, a user has typed in the top address and clicked the Find button. ZP4 then corrected the company name (chicao title becomes Chicago Title), corrected the street name (markt becomes Market St), added the secondary address (Ste 1300), added the state abbreviation (CA), and added the ZIP + 4® code (94111-5350). ZP4 also generated detailed notes documenting how the address was standardized. ZP4 includes complete source code examples demonstrating built-in address correction for a variety of standard databases and scripting environments (including C, Delphi, FileMaker, FoxPro, Paradox, and Visual Basic), and even source code for complete stand-alone applications like this one.
