In the UK, addresses are more vertical than in the USA.
(This was from a fax that came through to the office I worked at in England from 1995–1998.)
In Nairobi, Kenya, Africa, where Heather and I lived for five years, there are no street addresses. And that’s a city of 3–4 million people. There are street names but not building numbers. You have to ask good directions to find a place.
