Tech Notes


StreetPerfect.NET is an XML Web service with a SOAP API that allows you to add verification and lookup functionality to your application that calls on the US Postal Service and Canada Post databases of StreetPerfect.NET.

We’ve included some sample downloadable code to help you learn how to use StreetPerfect.NET at the bottom of this page.

The formal Web-service description document (streetperfect.wsdl) is an XML document that defines the format of messages that StreetPerfect.NET uses. The service description serves as an agreement that defines the behaviour of StreetPerfect.NET and instructs potential clients in how to interact with it.

StreetPerfect.NET is comprised of two functions:

  • Correct Address
    • This ensures that entered data is accurate
    • This web service function checks against a current database of valid addresses to verify that the street address, postal/zip code, and city represent a real location
    • Even if some of the information is wrong the entries can be corrected, ensuring accurate information
  • Suggest Address
    • This provides a method of rapidly collecting accurate information with minimal data entry
    • Valid address ranges described by the entry of a postal or zip code are returned and can easily be used to populate forms
