One of the available regions is "Earth", which offers global coordinates(they're a bit longer, four or five characters on each side of the dot).

Why not just use lat, lon, which can be shorter too?

Central park, NY - 40.78 -73.97

Hyde Park, LON - 51.51, -0.17

Those coordinates are obviously less accurate than the mapcode, and not at all any smaller.
