Korean house numbers

In most countries, when you are looking for a house you can follow the numbers on the buildings. They are arranged in a logical numbered sequence, right? Not in Korea. Next to House No. 1 could be house No. 88 or anything! House No. 2 will probably be half a mile away. Why? I wondered. Something to do with confusing the invading North Korean troops when they arrive, as somebody helpfully suggested? No. Apparently, they are numbered according to their age. So No. 1 will be the oldest house on the street. What happens if they tear it down and build a new one on the same spot, God only knows. Anyway, what it all means is that giving your address to a taxi driver is next-to-useless. You have to guide them every step of the way.
