Postcode Radius Scripts

Product Details

Postcode radius scripts ASP, PHP, Coldfusion
Free Download

All of our customers get free access to all example scripts
(PHP / ASP / Coldfusion) in the download area.
New: We added a free MS Access™ radius finder application to the download area. All source code is open, feel free to copy to your own app.


A typical task for a 'postcode radius search' is an online "Dealer locator". It allows your website visitors to find the nearest dealers to their home by entering their own postcode.

It can be too very useful in social network or dating sites (show members in my area) real estate or any other classified ads directory.

Having a database of localities with their latitudes and longitudes enables you to locate the closest cities to a set point (or within a radius of X).

To help you to implement a Postcode radius / distance search we offer free access to example codes in many scripting languages and programming languages like ASP, PHP, Coldfusion...

To achieve the highest accuracy the formulas in our example scripts take the earth's curvature into consideration.
