Address Finder API

SimplyPostcode™ offers an extensive range of Address Finder API's (Application Programming Interfaces) for both easy integration into a web site or bespoke windows desktop software.

V3 Open API: For web/desktop applications, we have an Open API JSON web service that takes a Postcode, Postcode + Part of address, or “Search as you type” words and returns a list of matching addresses, which can be used by almost any programming stack.

The user then selects an address from the list presented, and another call is made to the Open API to get the detailed address record and its Geolocation.

Desktop: We have a Git Hub example of V3 Open API Desktop App and how to implement it in different languages/platforms.

V2 Legacy API's: We also provide legacy SOAP, JSON and HTTMP/XML, can be used to implement Postcode Search functionality on any platform.
