Please can I get the list of all Counties, Cities and Zipcodes of an entire State?

Aaron, this should already be possible. If you select a State then a County but not a city the output window will list the ZIPs from the County.

could you please add the option to not choose a city , that way i can just get all the zip codes in the county? that would be helpful. i understand that some zip codes overlap county lines , yet i would still say to include any zip code that has even a slight portion within the desired county

As of June 3rd, 2020, it's not populating the county field drop-down after selecting the state.

Love your site! Is there anywhere like this page to do a reverse lookup using a set of ZIPs to get city/state/county? Thanks for providing such great info!
