Rio de Janeiro in detail
Postal services are decent in Brazil, and most mail gets through. Airmail letters to the US and Europe usually arrive in a week or two. For Australia and Asia, allow three weeks.
There are yellow mailboxes on the street, but it’s safer to go to a correios (post office). Most post offices are open 8am to 6pm Monday to Friday, and until noon on Saturday.
Branches include Botafogo, Copacabana and Ipanema.
