All of our customers get free access to all example scripts in the Download area.


A typical task for a ZIP Code radius search is a "Dealer locator" on websites. It allows your website visitors to find the nearest dealers to their home by entering their own ZIP Code.

It can be also 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 ZIP / Postal Code 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.
