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 00544.

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 centre 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.

Suggested New Features

Option to plot multiple ZIPs to build up a number of radius area

If ZIPs found are 90% or more of a city, suggest returning all ZIPs for that city

Hi David, this isn't possible right now but it will be added as a suggested new feature.

Is it possible to type in multiple zip codes to generate a map that has multiple radius' on the same page (i.e. see multiple coverage areas for a state)?
By David on 22/07/2016

Thank you so much! Really helpful tool!

Hi, This can be changed to miles. It is not intuitive by any means but if you select the User Menu at the top right of the screen, then Settings, then change Units Preference from KM to Miles. The units of the distance to the ZIP codes should then be in miles.

Wonderful tool but would have preffered distance in miles!!!

Hi, for information on the API, please get in contact.

Awesome, love this tool. Have you guys considered making this an API? I can't seem to find a single API that can return multiple zip codes within a radius of a coordinate.

This tool is absolutely FANTASTIC!! Thank you for all the hard work in making this happen.

Being a programmer of software I understand how difficult it is to create things like this, so I thank you for your efforts and for sharing it. To those with wish lists or feedback; REMEMBER THIS IS BEING GIVEN TO YOU FREE OF CHARGE. Please show some respect and appreciation of that in the way you word things. It never ceases to amaze me how many people look gift horses in the mouth and come across like they have every right to make demands. There are far too many people running around with a sense of entitlement. As though they are OWED the fruits of another's labors. Just sayin'

Mike , thanks for the comment. This page : Find ZIP Codes Inside a User Defined Area allows you to draw a custom shape.
By Free Map Tools on 30/06/2016

Hello, great tool. I'm wondering if there is a way to take this one step further and draw, or import polygon information to retrieve the zip codes within a rectangle, square, or irregular shape, rather than a radius around a point? Thank you!

Hi shaun, what OS and browser do you use? Testing at this end, the Toggle CSV works on any browser we test with. Referring doing it in bulk, please get in contact to discuss.
By Free Map Tools on 27/06/2016

The toggle CSV button does not appear to work. We would like to determine the zips within a radius in bulk

I would like to give OT therapy for patients in the 33647 zip code
