From the founders of Tomtom .

A mapcode represents a location. Every location on Earth can be represented by a mapcode. Mapcodes were designed to be short, easy to recognise, remember and communicate. They are precise to a few meters, which is good enough for every-day use

Mapcodes are a free, open way to make every house or location on Earth addressable by a short code. With nothing else except your mapcode, for instance, a navigation system will bring someone to within meters of your front door.

By example: my workadress:   
-  latitude/longitude 52.363323, 4.912090
-  mapcode: NLD 4N.0Q
