what3words is a universal addressing system based on a 3mx3m global grid
The result is precision location represented by a simple string of three words, kind of like a Diceware passphrase. I tried it for my own home address and got a surprisingly memorable string, easier than Eircode; your own mileage may vary. Probably most practicable for predominantly rural locations without signposted roads or postcodes — like Djibouti, which recently adopted the system as its national addressing standard. #link
