This is a tangent, but:

"That's particularly useful in places where street numbers are otherwise unavailable or places such as Japan and South Korea where streets are rarely numbered in chronological order but in other ways such as the order in which they were constructed, a system that makes many buildings impossibly hard to find, even for locals."

South Korea finished renumbering streets in 2011 and after two and a half years of trial completely switched to the new system in January 2014.
