Complicated. There's the city, and it'll be broken into neighborhoods with their own names. Then that will be broken down into blocks (approximately) with their own numbers. Then each building has its own number within the block. So you can only find a place based on its address (assuming no online mapping) if you already know approximately where it is.

Before Google maps became a big thing, taxi drivers would have massive books full of neighborhood maps which they would refer to when you told them the address you wanted to go to.
