We divided the world into 3m squares and gave each square a unique combination of three words. It’s the easiest way to find and share precise locations. Over the last year, what3words has been used in 193 countries, and our monthly active users continue to grow at an impressive pace. Our tech is used by emergency services, delivery companies, eCommerce businesses, ride-hailing apps and NGOs, and is integrated into the navigation systems of millions of cars around the world.
