What3words is revolutionising the way we communicate location by dividing the world into a grid of 3m x 3m squares, and given each square a unique combination of three words: a what3words address.

Now everywhere has its own address, from the side of the motorway to parking spots and remote viewpoints. For example, ///topmost.super.headboard identifies a precise location of a hard-shoulder along the M60 where drivers can pull over in case of an emergency.

The app is free to download for both iOS and Android and works entirely offline – making it ideal for use in areas of the UK with an unreliable data connection, such as rural back-roads and motorways.

What3words can also be used via the online map at what3words.com.

The app is available in 54 languages to date, including welsh, arabic, chinese and polish.

What3words is now used by over 85% of UK emergency services – police, fire and ambulance – and has become an important tool in the emergency toolkit.
