In Albania, there are practically no house numbers anywhere. People somehow live in a system where there are only street names and that's it.

Mail gets sent to addresses like "Tirana, Kemal Stafa Street, the house near the mosque, John Smith". And it works. It's up to the postal workers to know all these people.

In my opinion, this solution doesn't scale very well. Especially in a world where people are constantly moving.

I mean, just the other day I was moving into a place, and the location on the map was marked incorrectly, with only a pretty long street name in the address. I had to ask locals for directions.
