Until very recently, Costa Rica did not have a traditional address system. Instead, locals used directions from landmarks to explain location. Directions to a friend’s house might be explained as “100 meters north of the supermarket, 100 meters east and 25 meters west, the blue house on the left.” (100 meters = 1 block) In 2010, the country began implementing an address system in San Jose – and there are plans to expand throughout the Central Valley.
