The world is poorly addressed. This is frustrating and costly in developed nations; and in developing nations this is life-threatening and growth limiting.
what3words is a unique combination of just 3 words that identifies a 3mx3m square, anywhere on the planet.
It’s far more accurate than a postal address and it’s much easier to remember, use and share than a set of coordinates.
Better addressing improves customer experience, delivers business efficiencies, drives growth and helps the social & economic development of countries.

what3words is a universal addressing system based on a 3mx3m global grid.
Each of the 57 trillion 3mx3m squares in the world has been pre-allocated a fixed & unique 3 word address.
Our geocoder turns geographic coordinates into these 3 word addresses & vice-versa.
As it is an algorithm our solution takes up less than 10MB, small enough to install on almost all smartphones and works across platforms and devices.
what3words is a plug-in for businesses and individuals, via an API, to enhance their own products and services with simple and precise addressing.
Why is it important ?
Around 75% of the world (135 countries) suffers from inconsistent, complicated or inadequate addressing systems.
This means that around 4 billion people are invisible; unable to report crime; unable to get deliveries or receive aid; and unable to exercise many of their rights as citizens because they simply have no way to communicate where they live.
For example, it means that in remote locations water facilities can’t be found, monitored and fixed; and schools, refugee camps and informal settlements remain unaddressed.
Even in countries with advanced address systems, people get lost, packages aren’t delivered, and businesses and tourist attractions don’t get found.
Poor addressing might seem no more than annoying in some countries, but around the world it hampers the growth and development of nations, ultimately costing lives.
We want to give everyone in the world the ability to talk about a precise location as easily as possible.
Everyone and everywhere now has an address.
