what3words is a global grid of 57 trillion 3mx3m squares. Each square has a 3 word address that can be communicated quickly, easily and with no ambiguity.
This is a fascinating project to give a location anywhere in the world when standard addressing fails or does not exist.
Even in developed countries, addresses can change. In my lifetime (about 3 decades) my father’s address has changed three times.
First, it was a Rural Route and a Box number: Route 2 Box 4794.
Then, when the county decided it needed to have real addresses to aid emergency response, it changed to 1511 Kimble Road. Finally, it has changed yet again to a new road name and number because of a shift in how the county decided to handle addressing.
So even in the United States, 60 miles from the Washington, D.C. addressing is still a problem. He lives out near hogs.dogs.improving which is a fitting address for my hometown.
