What3words (English Wikipedia)

"Location Encoding Systems". checkmypostcode.uk. What3Birds...is a parody of the commercial What3Words system, which isn't suitable for this website as it doesn't have a published, open source algorithm. It does, though, work - every postcode on this website has a unique, three bird code. The list of birds was taken (in simplified form) from the British Ornithologists' Union's official list of birds recorded in Britain.
