You can also find a comma separated list of the ZIP codes, states and cities in the text boxes below the map in the CSV Output section.

Looks like the user defined area is not allowing to select any points

I have tried a couple of KML files. they are pretty large for a KML (15kb smallest) but out of the one I have tried, none of them will load the zip code list. When I click to load the Zip Codes, the button just stays on "Please Wait"

David, things are working the same as they did a few months ago. Can you try it again? try a different KML file as a reference test?
By Free Map Tools on 8th August 2023

I am not able to load in my KML file and receive a list of the zip codes from the polygon. When I tried a couple months ago it worked, but now nothing loads in after I click "Search for Zip Codes".
By David R. on 7th August 2023

It would be great if there is a way to download the list and map afterwards!

I wish there were a map that showed all zip code boundaries, from which a user could zoom in and click on individual zip codes areas on the map to highlight them and "output" a list of those selected zip codes.
