What is what3words?

what3words is a really simple way to talk about location.

We have assigned each 3m square in the world a unique 3 word address that will never change. For example filled.count.soap marks the exact entrance to what3words’ London headquarters. 3 word addresses are easy to say and share, and are as accurate as GPS coordinates.

Our vision is to become a global standard for communicating location. People use what3words to find their tents at festivals, navigate to B&Bs, and to direct emergency services to the right place.
