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

BM, sorry, this is not possible but there is a paid-for API that can be used to get the back-end functionality. Get in direct contact if you wish to discuss.

Hi David, can you try adjusting the accuracy on the drive time search to a lower setting to see if this helps?
By Free Map Tools on 7th May 2018

Followed these instructions - - but after submitting to get the zip codes after loading in the map outline, it just gets stuck on "please wait" and never pulls in the zip code data. Is there a bug at the moment? Thanks!
By David on 2nd May 2018

Hi Dan, not 100% what you mean. Can you give a bit more detail please?
By Free Map Tools on 13th December 2017

Is there a function that allows for a user defined area on the map to be converted to drive time?
By Dan on 13th December 2017

Hi Jennifer, if you define (draw) an area on the map then click [Search For ZIP Codes] it should return all ZIP codes inside.

I'm having trouble getting this page to work....I can't copy and paste zips or get the map to work. I've tried in Chrome and IE and cannot copy or paste or enter text in the fields. What am I doing wrong? Was excited to find this page as I'm trying to pinpoint only certain zips for a project for work. Any help you can provide would be greatly appreciated.
