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

Hi Dan, not 100% what you mean. Can you give a bit more detail please?

Is there a function that allows for a user defined area on the map to be converted to drive time?

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.

Anita, no plans currently

Any plans to include the Zip[Plus]4 data?
By Anita on 18th September 2017

Unfortunately we do not provide ZIP[plus]4 data
By Free Map Tools on 14th September 2017

This is great. Is there a way to get the zip 4 in the csv window?
By Anita on 12th September 2017

Add county names as part of the output?

On 6th September 2017, not as such but you could use Find ZIP Codes Inside a Radius and use the airport address as the centre of the radius.
By Free Map Tools on 7th September 2017

Do you have a tool that will query which zip codes are within a certain radius of an airport code?

DEA, unfortunately there are few options to export the map image.
By Free Map Tools on 5th April 2017

Is there a way to export this map file?
By DEA on 5th April 2017

Will, unfortunately it is not possible to define the area in this way on this page.
By Free Map Tools on 3rd April 2017

This is great! However, I was wondering if it would be possible to specify the bounds of the box by latitude and longitude. For instance, enter the lat, lon for the Northeast corner and the Southwest corner of the box. Besides that, Thank You.
By Will on 2nd April 2017

Thanks, it works perfectly now!

Jw. Thanks for your comments. It was always trying to update straight after any change to the polygon. This made it slow and seem to get set on the original states. Now it should wait until you decide to search again.
By Free Map Tools on 29th March 2017

Can you remove the state selector box, or at least correct it so it shows ALL states by default? Currently when I'm configuring my selection, I only get a couple of states, and if I add states outside of that the page just freezes for a short time and doesn't actually add those selections.
