I think there’s a bit of false equivalence going on here as well regarding zip codes (several thousand addresses, or thereabouts) and a UK postcode (maybe 10-15 houses).
You could genuinely address a letter to me using something like:
4, L226ET
That’s all it would take. No, that’s not my address, characters within changed to protect the guilty, but my address could look just like that.
First was a house in a small cul de sac – with no number just a name. Second was a flat – there are two number 1s in the same post code.
That is, in a navigational sense, superior to ordinary street addressing.
Take something like N90 W17567. Once you understand the system, you already know approximately where the destination is: the road lies about 90 blocks north of the baseline, while the property is about 175.67 blocks west of the north-south baseline. The address is essentially a human-readable coordinate pair.
In other words, if someone gives you an address like N90 W17567, and you understand the grid, you immediately know roughly how far north and west the property is without having to look up the street or pull out a map.
I have a feeling that someone has to have a special interest in all that. Hell, maybe I should write a blog post.
Was quite interesting, especially the fact that house numbers were invented multiple times for different reasons and with different systems.
It got quite repetitive though, and I quit after roughly half of the read, when the even/odd number system was explained for the third time. Seems to be written with heavy AI assistance.
On a side note, boy, this page is a nightmare of low-contrast design and ads everywhere on top of that.
Unrelated, Japan (shocker) has a totally different system, at least they used to.
So the first house may have a number somewhere between 0 and 20, depending on how far the entrance is from the corner. The last house number on that block will be below 100.
On the next block, the first house will be numbered somewhere between 100 and 110-120, depending on how many meters the entrance is from the second corner.
This system is amazing. Without much mental effort, you can understand how many blocks you need to walk to reach house 340 if you are starting from the first block.
In Barcelona, you can walk 400m and still see only four house numbers. It doesn't make sense at all.
They also use things like 26A, 26B, and 26C because each house cannot have its own number. And they also use ranges. My house, for example, is not Streetname 26. It's Streetname 26-28. Bonkers.
