Software HTTP/XML Web Service

V2 Legacy HTTP/XML Web Service offers a simple way to interact with our postcode address lookup service. A simple web request URL returns XML which can be read by almost any programming language.   This service provides up to date Royal Mail address information, that is updated daily.

This data source can be used by any web server or programming language that supports a server-side scripting language that can parse JSON data, to provide Postcode Software Lookup and Nearest Store locator within your software/Web site.

The service is available across a simple HTTP protocol. Each request is a standard HTTP GET request with the query string forming the request parameters, and returns the address Lookup information as XML data feed.

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. More info about Open API
