Welcome to the free Zip Code Distance application from CDX Technologies. This software tool will allow you to calculate straight line (as the crow flies) or driving distance for any pair of US zip codes. Just enter your two zip code in the boxes above and press the Generate Report button. The distance can be optionally specified in miles, kilometers or nautical miles. Bing Maps is used for the driving distance calculation and displayed map. CDXGeodata is used for the straight line distance calculation

An example report for zip code 07869 to 08033 is shown on the right side of this screen. The report contains the straight line distance, driving distance, distance type, map and the latitude, and longitude for both zip codes.

Do you need to analyze thousands of zip codes or addresses? If so, we recommend using our CDXZipStream product. CDXZipStream can analyze both straight line and driving distance and also supports Canadian and worldwide Postal codes. Our CDXGeodata multi-platform web based service allows these functions to be access via a REST (REpresentational State Transfer),API interface.
