How three words can save a life

Street addresses or the 'closest dispatchable address' do not always point to the right location or entrance, and many parts of the world do not have an address, like parks, forests and waterways.

what3words is an easy way to identify precise locations. Every 3 metre square in the world has been given a unique combination of three random words: a what3words address. For example, ///tower.defeat.land will take you to the top of Parliament Hill, Hampstead Heath, London. It's much easier to say a what3words address than to try and describe a location based on landmarks in an emergency.

The app is free to download for both iOS and Android devices, and works offline, making it ideal for use in areas with an unreliable data connection, such as hiking trails and campsites. what3words can also be used via the online map at what3words.com. The technology is available in 50 languages and can be used anywhere in the world.

Over 85% of the UK’s emergency services are now using the system in the Control Room, and out in the field, to respond to incidents more effectively.
