what3words is the easiest way to describe any precise location. Every 3 metre (10ft) square in the world has been given a unique address made of 3 random words. what3words addresses are precise, enabling them to specify building entrances, unlike a street address which identifies an entire building. It can easily be integrated into products, platforms and apps giving businesses access to precise location data for deliveries, in-car navigation, pinpointing infrastructure assets, ride-hailing, emergencies and more.
