Postcode Programming API  Get Thoroughfare/Street Address from SOAP Web Service:


Thoroughfare/Street Address Search functionality:

  • Postcode is entered
  • User presses search button
  • Address filled in apart from House Name/Number
  • User manually types in House Name/Number, unlike Full Address

The following example calls our server to retrieve Thoroughfare/Street address for a given postcode. The Thoroughfare Address is a cut down version of the Full Address, basically it does not contain the Building name or number. Therefore the programmer should allow the user to enter the House Name/Number for the address. These licenses are cheaper than Full Postcode data.

  Please note: Section 3.5 of the terms and conditions state: "The Customer, when using the Postcode Lookup service via Web Service, must make sure each user is identified by a unique Computer name, in each call to the Web Service if used internally”. In simple language this means that each user must be identified by a unique computer name, if used by a company employee. In the above example "UserID" was passed as the computer name.
