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 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.

Hi Mike, unfortunately this is not available.

Is there any API call which can be used, directly?

Hi, we don't output county codes, only the county name in the last text box.

Is there a way to find county codes within a certain radius?
By Ashlie on 28/04/2015

Hi Chuck, Has it worked before for you? What parameters are you searching with? If you simply click on the map on a populated area, do any ZIPs come back? Thanks

Doesn't seem to be working. I put in the zipcode, chose Draw Radius. It will draw the radius but not list any zipcodes.Says 0 found I attempted from multiple PCs, and used Chrome and IE. Exactly What I am looking for, so hoping this is a temporary bug.

Hi, For each ZIP, an assumed center point is made and this is used to determine the county and city.
By Free Map Tools on 26/04/2015

Awesome tool!!! Just one question - how are the county and city determined? I am just curious since zips can often go across county/city lines

I am looking for all casinos located within a 4hr driving radius (200mi)from the center of Chicago (60601). I have over 3000 zip codes, is there a way to isolate just casinos?

AWESOME TOOL - Just made my job 100% easier!

Hi Julia, counties can be extracted from the bottom text box. You could copy/paste in to Excel. In terms of processing more than one at once, sorry this is not possible.
By Free Map Tools on 15/04/2015

Would like a list of counties within 25 mile radius of an address and ability to export to excel. Also is there a way to load multiple addresses at once - for example all the store locations
