ZIP Codes






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 delay, the results will appear inside the area. 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.

This is absolutely amazing! Thank you!

Excellent and easy to use. A nice to have feature would be the ability to filter by state or to follow a geographic feature (i.e. highway) but these would be minor enhancements to an otherwise super useful tool.

Is there a way to zoom in on the map much more easily, similar to what google maps does of double clicking. Or at least give me the option to filter by state.

I did not realize there was a save and load area function on this website, in the upper right! This has saved me a ton of time, thank you for these tools.

Is there a way to combine this with the How Far Can I Travel? to get zip codes within an area defined by distance? Right now I am doing it manually by comparing the How Far Can I travel map area to points manually created on this map.

Hi Eduard, the best you can do is use this page to get USA cities. It is not currently possible to find the cities for other countries.
By Free Map Tools on 25th October 2016

And I hope to get cities of other countries. Is it possible? I am sorry for many question. thanks
On 24th October 2016

Thank you for your wonderful map tool. But is there any getting cities name tool? I hope to get only cities, states and countries. Please help me. Thanks

Steve D, how many points? it will have its limits once the shape gets too complex.
By Free Map Tools on 16th October 2016

Fantastic tool! Thanks. I created a complex user defined area with a lot of points following state boundaries along rivers. The app seems to be hung up "List of Cip Codes found..." but nothing happens.

Hi Al, not quite sure what you mean. Is it like a state area x miles extra?
By Free Map Tools on 26th August 2016

Excellent tool! Would there be a way to define an area within X miles around a state, and have the map automatically draw this?
By Al on 25th August 2016

On 22nd August 2016, we have now added labels to the markers
By Free Map Tools on 23rd August 2016

If this had a way to add zip code labels it would be 100% perfect, but has already saved me days of work.

Tpierce, thanks for the kind comments.
By Free Map Tools on 5th August 2016

I have used this tool several times, it has saved me DAYS worth of work. Thank you Thank you!
