@chrysauthorJun 13.2005 — #I think some of the zipcodes that are missing are in Hawaii and Alaska... I just made the dropdown value of Entire country to 6000 miles, which I thought would be enough to cover it.
I just put that there to demostrate how quickly it can calculate the distance of every single zipcode within 6000 miles, less than 2 seconds.
I will do some more quality assurance for the time being.
