I wonder if it’s like when any business tries to get on Google Maps, they have to make sure the address is correct because an address can be valid if no city is provided. I used to see it all the time on Google Maps because the place got imported to where it could have been valid but looking at it for more than 5 seconds would tell you it’s off.
An example for my area is Tamiami Trail for US 41.
If you said 14400 Tamiami Trail that could be a valid place for Osprey, Venice, Sarasota, Port Charlotte, and for the rest of Southwest Florida.
