We’ve already seen here at this blog how streets are numbered in Brazil. I will explain today how flats [apartments] are numbered.
The system used is Brazil is easy to understand as it follows the logic of the system used by hotels. The first number indicates the floor, the second number shows the door (the different doors on the same floor are identified with letters and not with numbers). Two examples:
Avenida dos Libertadores, 345, apto. 163
This address belongs to number 345 on Avenida dos Libertadores. The flat/apartment number, identified by the number 163 belongs to door 3 on the sixteenth floor.
Rua da Amargura, 126, apto. 42 C
This address belongs to number 126 of Rua da Amargura. The flat/apartment number, identified by the number 42C, belongs to door 2 on the fourth floor. Letter C shows there are three blocks of flats/apartaments and that the address we are after is on block C.
