In Brazil, at the age of 18, all Brazilian citizens are supposed to be issued a "cédula de identidade" (ID card), usually known by its number, the "Registro Geral (RG)", Portuguese for "General Registry". The cards are needed to obtain a job, to vote, and to use credit cards. Foreigners living in Brazil have a different kind of ID card. Since the RG is not unique, being issued in a state-basis, in many places the CPF (the Brazilian revenue agency's identification number) is used as a replacement. The current Brazilian driver's license contains both the RG and the CPF, and as such can be used as an identification card as well.
