There are lots of rural places the USPS doesn't deliver to. They require you to get your mail at a PO Box at the nearest post office, or have a mailbox at a common spot on the nearest public road (which might be a fair distance from your house).

They won't deliver to the house but they'll still deliver to that area. Amazon/etc wouldn't even deliver to the area without the infrastructure of the USPS.
