The Mongol post has several hurdles to jump over in order to deliver mail: a quarter of the country’s population is nomadic, roads rarely have well-known names, and the country is huge but barely populated (it’s twice the size of Texas but has a tenth of the state’s population). Now the Mongolian government is teaming up with a British start-up called What3Words in an attempt to make the postal system more effective. Instead of a traditional Western-style address, the system gives each location a three-word name: Engine.Doors.Cubs. or Chief.Score.Locked. It’s a fascinating approach and reads somewhat similarly to a poem. Find out how it works on NPR.
