what3words

what3words is a global addressing system. It has divided the world into squares measuring three metres on each side and given each one a unique address made of three random words, so people can name a precise spot such as a delivery entrance or a parking space.

What what3words offers

• Three-word addresses — a fixed address for every square, which does not change as towns develop.
• Consumer app — lets people find, save, share and navigate to exact locations.
• Integration options — ways for businesses to add the addresses into their own products, platforms and apps.
• Offline use — the addresses are fixed, so the system also works on devices without a connection.

Who it works with

It is used by individuals planning meet-ups, trips and taxi pick-ups, and by businesses and governments for delivery, logistics, navigation and emergencies. The company says over 650 businesses, government bodies and charities in more than 170 countries use it.
