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 small delay, the results will appear inside the area. If you hover over or tap a marker, you will see its ZIP code.

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.

You can filter states in/out of the result set using the State Filter control. You can also edit and adjust the area afterwards to refine your search area

This is a fantastic tool. Just found it. Exactly what I needed to target ad locations. Thank you so much. iMac using Chrome.

We have now added a search icon on the map to allow you to jump to a ZIP or location.

Great tool - appreciate the effort. Any roadmap plans to define a 'starting' ZIP code or location to narrow/zoom the map, then the user can draw a perimeter from that point?

Bravo! thanks for this tool!

TG, sorry, this is not possible.

Hello, is there a way to search multiple counties and be "taken" to them on the map while being provided data about them such as zip codes? Thanks!
By TG on 24th July 2020

You can use the User Menu (top right) > Save Area option. Then on a future visit User Menu > Load Area to recall the saved area.

Am I able to save my map to revisit later?

Thanks for the feedback

Thanks so much this is an amazing tool! Helped me determine zip codes for our businesses delivery region
By Aaron M. on 29th April 2020

Awesome tool.
By Luke on 11th October 2019

so much more difficult to see/identify cities - please revert to the old UI
By anon on 17th June 2019

Love this! Thank you very much for this free service. Would it be possible to go back to the old map though? This one is a lot more difficult to see and identify cities/towns. Thanks again!
By IC on 7th June 2019

Really love this tool. It's the only one that I've found anywhere that lets you generate zip codes from a map, rather than the other way round. It would be insanely useful if you could upload a kml file to import an existing map :)

Thank you for adding [Auto-zoom after each point added?] !
