Find ZIP Codes Inside a Radius

Map of the USA where you can specify a point and a radius to search within and return all the ZIP codes found inside that radius.

Radius Search Map


Show Centre Marker? Show US County Borders?

Step 1 : Radius km (maximum = 1000km) OR miles (maximum = 625 miles)

Step 2 : Click on map OR Place radius by location name or ZIP code :

CSV Output

ZIP Codes




Input a radius to search within in KM or miles. Click on the map or type in an address or ZIP code on the center of your search. After a delay, the results will appear inside the radius. If you hover over a marker, you will see its ZIP code.

You can also find a comma separated list of the ZIP codes in the large text box in the CSV Output section.

There is a limit to the radius because excessive results can take a long time to load and some web browsers struggle to load them all.

I can confirm that glitch - I use this page to define geographic territories to use for lead search. When I incorporate the Zip Code list, usually about 20% of the results seem to be outside the US, even.

On 08/04/2014, can you let us know the ZIP codes that are outside the 2 miles?

Great tool! Thank you!

Is there a way to print this report out?

I absolutely ADORE using this tool. I thank you for developing it. Just a head's up. There may be a glitch. When I ask for it to search for zip codes within a 2 mile radius of 75226; it supplies me with zip codes beyond that.

Hi Tony, each zip code is assumed to be in a single location (the point that best represents the center). All measurements and searches are then based on that single point.
By Free Map Tools on 07/04/2014

And how are the zipcode markers placed? are the markers in the center of the zipcode?
By Tony on 07/04/2014

How does the software calculate distance? Is it from the center of the zipode or if any of that zipcode passes through the radius?
By Tony on 07/04/2014

You Rock! Thank you for this App.

Hi Brian, Which AZ ZIP code did you use?
By Free Map Tools on 30/03/2014

I put in AZ zip code and recieve back MA zip codes. What's up?

I've been using this awesome tool for about 5 years to get zip code radius. Do you have a way to show the counties in a radius?
By Lisa D. on 27/03/2014

Is there a way report the postal codes with the states that each postal code is part of? Awesome tool. Thank you!

Sam, please have a look at [Upload and Plot USA ZIP Codes] inside [Import Data] on Generic Map Generator.
By Free Map Tools on 21/03/2014

Question please... If I have a list of zip codes, can I enter them anywhere so I can see where they are on a map? In other words, doing this tool in reverse? Thanks.
By Sam on 21/03/2014

Very helpful too. Thanks
By Ted on 20/03/2014

Awesome tool; use it weekly. I also would like to suggest adding a feature that allows some kind of a free-form border drawing of zip codes that fall within that border. Oo, and one more thing%u2014what about allowing user accounts, and users would be able to save/select pre-defined ZIP groups.

Thank you for the New Line option. That is extremely helpful for me!
