Some Latin American cities were designed as grids (100m x 100m squares), and numbering of blocks spans a hundred per block (first block is 0 to 100 house numbers).

So if you are at 200s in one street and are looking for a house at 1200s, you know you are a kilometer away.

This with numbered streets is awesome to navigate. Buenos Aires has the first, but named streets. La Plata in Argentina has both.

If you are into maps see an air pic of La Plata.

Chicago is like this, there are numbered streets on the south side, but all the streets on the north and west sides are named, however they're very good about putting the grid numbers on the named street signs, so it's easy to figure out where you are. 100 addresses per block, 8 blocks to a mile, so if I'm at Western and Belmont, that's 2400W 3200N, so 3 miles west and 4 miles north of downtown. All the Metro stations list the grid numbers on the signs at the exits too
