PostCoder API Professional

A developers' toolkit which includes a full range of PAF® and GeoData search functions maximised for efficiency and speed, with working examples for many standard Windows development languages. This allows you to seamlessly integrate address lookup and validation into your own software. It is our most popular product because it is so versatile. Unlike our Web services, PostCoder API Professional is installed along with the data on your server, giving you more control over address database updates and configuration management.

You can also access this service immediately, switching from a free trial to 'live' with no interruption of service, meaning you can be up and running in no time at all.


Developers of web applications for service companies such as property search websites, utility companies, telephone companies and online retailers find this product very useful. It is ideal for online order and registration forms, nearest lookup and map display.

PostCoder Web Nearest store locator

This store locator software specifically provides a 'find my nearest' search for your website. PostCoder Web Nearest comes with the code you need to integrate it into your website. Additionally you provide the service with a list of points to search against (e.g. stores, suppliers etc). You could display the X nearest results, or all results in nearest order, display the distances in miles or kilometres or display sponsored links first- whatever you choose. Visitors to your website enter a Postcode or town name and your website will inform them of the nearest outlets within the specified distance.
