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
