In my limited understanding so far: You cannot order to any address, only to residential addresses that USPS ships to (as indicated by their Residential Delivery Indicator). Specifically, you cannot order to commercial addresses and PO boxes. Resale is not prevented but (intentionally or not) limited by the distribution of only 4 tests per home, regardless of how many people live there. This means that poor folks where typically many people share a household get fewer tests per person to begin with, while more affluent folks (who are less likely to resell the tests) get more per person.
