To make what3words precise enough to refer to an entrance or parking spot, it needed to be accurate to a 3m square. This meant we needed 57 trillion addresses to cover the world, and three words allowed us to create 64 trillion addresses – covering the entire world with quite a few spare!  If we’d used only two words, we’d only have had enough for 1.6 billion squares.
