When I was in undergrad, I spent a summer in Taipei. One of the things I remember about that summer was how difficult it was to locate building addresses. Sure, there was the whole language barrier thing, but I swear that some of those alleys (which I loved) didn’t follow a consistent numerical logic.
It turns out that a lot of the world is actually poorly addressed. Think about the favelas in Brazil. How are they addressed? (Not actually a rhetorical question; I’ve never been.)
A company out of the UK called what3words is trying to solve this problem. What they have done is created a 3m x 3m grid of the entire world and assigned a 3 word address to each square. Apparently that translates into about 57 trillion squares.
This is similar to long / lat coordinates, except that 3 words are far more user friendly than a string of numbers. They are more easily remembered and more easily communicated to other people. The front door of the Starbucks in my neighborhood looks to be migrate.stunner.racing.
One service that has built upon the what3words platform is a bike taxi service in Delhi that offers female drivers for female customers. It’s called Bikxie Pink and the 3 word addresses aim to solve the safety problem of inefficient pick-ups and drop-offs.
Even in places where addressing isn’t generally a problem, I could see what3words helping. Interesting platform.

Depending on where you live, street numbering may not be something you’ve given a lot of thought to. In Canada, and in many other places in the world, the convention is usually to start on one end of the street and count up – with even numbers on one side and odd numbers on the other.
In many cities in the US, they’re even more rational. The streets themselves are numbered and the addresses indicate location. For example in Philadelphia, where I used to live, if you were going to let’s say 1750 Walnut Street, you would know that it’s between the cross streets of 17th Street and 18th Street. It’s a kind of hyper-rational approach, which lets you know precisely the number of blocks you need to go to get to your destination.
But not all countries and cities are this rational.
According to this Economist article – which a friend of mine forwarded me over the weekend – Costa Rica actually had no street numbering system until about 2012. Which means that directions were all based on landmarks: “100 metres south of the McDonald’s.” It seems almost hard to believe. But I guess that’s why ¼ of all mail was getting lost.
Of course, there are also lots of variations in between these two extremes.
Japan numbers its buildings, but they’re often clustered together in blocks and have no particular order or logic to them. Brasilia (Brazil) also assigns numbers based on sectors, quadrants, and blocks. And in Ireland, where I also used to live, they actually never adopted postal/zip codes. They’re one of the few developed countries in the world not to do that – though it’s coming next year.
If your city or country has a unique numbering system or you’ve come across one in your travels, I would love to hear from you in the comment section below.
There are obviously practical reasons to adopt an easy to understand numbering system. People need to be able to figure out where they’re going. But I would also imagine that there are spatial implications to the way you number and the way you organize your city.
