Click on the map to start drawing an area. Once you have defined the area in which you wish to search, click the [Search For Zip Codes] button. After a small delay, the results will appear inside the area. If you hover over or tap a marker, you will see its ZIP code.

You can also find a comma separated list of the ZIP codes, states and cities in the text boxes below the map in the CSV Output section.

You can filter states in/out of the result set using the State Filter control. You can also edit and adjust the area afterwards to refine your search area

DEA, unfortunately there are few options to export the map image.

Is there a way to export this map file?
By DEA on 5th April 2017

Will, unfortunately it is not possible to define the area in this way on this page.

This is great! However, I was wondering if it would be possible to specify the bounds of the box by latitude and longitude. For instance, enter the lat, lon for the Northeast corner and the Southwest corner of the box. Besides that, Thank You.
By Will on 2nd April 2017

Thanks, it works perfectly now!

Jw. Thanks for your comments. It was always trying to update straight after any change to the polygon. This made it slow and seem to get set on the original states. Now it should wait until you decide to search again.

Can you remove the state selector box, or at least correct it so it shows ALL states by default? Currently when I'm configuring my selection, I only get a couple of states, and if I add states outside of that the page just freezes for a short time and doesn't actually add those selections.

Hi Ben, Very accurate could have too many points/sides so this page struggles to process the area. Simpler shapes are more likely to be processed without issues.
By Free Map Tools on 28th March 2017

FYI, when you use the "Very Accurate" setting on the "How Far Can I Travel" tool and save it and try to run it here, it does not run. I made a 60 mile radius, left it running here for about four hours, and it never gave zip code.

Glad to hear its working for you again.

Map is working now! You guys are great. Complete life savers.

Please try again... an issue was found and fixed.

The map is not loading for me either, I have tried clearing cache, browsing history, using different browsers (Chrome and IE). Other maps work on the site, just this one not loading.

I love this tool but the map is not loading. I cleared my cache and also tried Edge (after trying chrome), still not loading

Hi, can you try clearing your temporary internet files (internet cache) or try a different web browser?
By Free Map Tools on 21st March 2017

It's not loading now.

Hi, we have now added a State Filter to allow you to control which US States are included/excluded. Hope this helps...
By Free Map Tools on 2nd March 2017

I agree with the suggestion to filter out states. I use this tool to pull in zip codes for my company's services and need to isolate one state at a time. Otherwise a perfect tool! Thanks!

This is absolutely amazing! Thank you!
