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 :

Please Note : 3 or 4 digit ZIPs should be padded with zero's to produce a 5 digit number for the most accurate results. So 544 should be input as 00504.

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.

Wow, great tool for finding the zips inside a radius of specific location.

The map doesn't load

For use with government applications a "percent of each zip codewould be very helpful

This site is great! Exactly what I was looking for.

Can you add the option of a driveable-mile radius in addition to what you have now -- a straight-line radius? And then possibly an API :)
By Mark H on 04/11/2015

Is it possible to show how to do this on our own website, for example, Find all zip codes within 50 miles of Madison, Wisconsin, and it just returns the zip codes comma delimited?

Hi peg, so you are saying it will appear eventually, but takes a very long time? Does it do this every time? Thanks

I love the site but suddenly the map doesn't populate for minutes when I load the page "Radius around a point on a map"

Jeanne, the page Find German Postal Codes Inside a Radius has just been added.

This is a very useful tool and thank you for creating it. Maybe if you like this idea, you could give the UI the ability to search as it does now, but toggle states so you can find the zip codes that are only in a specific state. An example is that I ran a repo company in Northern Virginia and we were located at the northern tip of VA and we covered 50 miles out, but we only covered VA even though WV, DC and MD were well within 50 miles and it would be helpful to find the zip codes only in my state within this radius. I am sure others would like this kind of functionality as well... Regardless, great idea and thank you.

What about other countries? like Germany and Belgium?
By Jeanne on 14/10/2015

I have and it works... but out of laziness I thought I'd see if I could avoid an extra step :)
By RCG on 08/10/2015

RCG, have you tried find and replace in a text editor?
By Free Map Tools on 07/10/2015

I would love it if I could change the delimiter to something other than a comma... specifically a semicolon.
By RCG on 06/10/2015

Hi, if you wish to filter by state, you could use the output in the Combined text box, copy it in to Excel (or equivalent) then filter on the State column.
By Free Map Tools on 05/10/2015

This is very helpful. Is there a way to filter by state? I need zip codes within a 50 mile radius of a location in Baltimore but I only want the results to include Maryland zips. Thank you.
By K Burke on 05/10/2015

This is great, but I wish there was a feature to break it down. I need to know all zipcodes between 0-50 mi and 50-100. When I type 100 miles into radius I get all zipcodes within that radius, then manually erase the 0-50. Keep up the good work tho
By Alex G on 30/09/2015

Thanks for all your efforts... its awesome.

Abhi, you can copy and paste from the text box in to excel. It is best to click the [Toggle CSV or New Line] button to get them in a single column first.
By Free Map Tools on 23/09/2015

I want the results of zip codes as an excel file.. or can I download those as an excel file format?
