We often get asked how @what3words differs to other mapping software. @what3words splits the world in to 3m by 3m grids & assigns a unique 3 word code to each. When you give these words, we can understand where you are, better than being told "in the green bit off the blue road"pic.twitter.com/348I8B9HoC
Several emergency services support what3words but you can always ask your local services if they do too!
