Since I'm already talking about it, might as well explain how it works for anyone curious.
Our address system kinda reflexts the fact that 1) cities in Colombia (just like a lot of latin america) tend to be a lot more gridlike than cities in the US, and 2) We very rarely do street names here, and stick almost exclusively to street numbers.
(Neither of these two things are like. big innovations ofc, I know grid-like city layouts and numbered streets also exist in the US, but they're not anywhere as universal as they are here)
Streets are numbered in a standardized way, where the basic concept is that streets going west-east are called "calles" while streets going north-south are called "carreras", and both calles and carreras are numbered sequentially starting at one edge of the city (ofc there are some special terms for diagonals or types of streets that can't be approximated neatly as cardinal directions, but that's the basic concept). So if you see something like "calle 42" you know it's the 42nd west-east street, or if you see "carrera 15" it's the 15th north-south street.
An address includes three numbers, with one being the street it's on, the next being the street it intersects before reaching the address, and the other being the distance from the intersection. So on an address like "Calle 54 #93-42", it tells you: 1) You're on the 54th west-east street.
2) You need to find where it intersects with the 93rd north-south street.
3) The building you're looking for is roughly 42 meters away from this intersection along the Calle 54.
But the number for distance from the intersection isn't actually a precise measurement: The numbers are fudged a bit to make it so that all odd-numbered buildings are on one side of the street, while all even-numbered buildings are on the other, so if you care to take that into account (which I usually don't) it can even tell you that information.
So it's a system where the address itself gives you the geographical location of the building using a cartesian grid. And if you compare it to the address of your current location, it allows you to immediately conclude things such as its cardinal directions relative to you, and roughly how many blocks away it is in each direction. Which in turn makes it like. Almost trivially easy to find an address even without any directions, even when visiting an unfamiliar city for the first time.
I'd say the system's biggest weakness is, however, that it necessarily assumes the city is a grid. Which generally works bc, as I said, colombian cities are generally pretty grid-like, butttt... none of them are a perfect grid, most cities feature at least a few areas that break the grid pattern, and the address system starts getting noticeably messier the less grid-like the area is.
