Identity document
Other forms of officially accepted identification include the driver's license and the birth certificate. However, these are accepted only in limited circumstances and cannot take the place of the ID Card in most cases. The ID Card is mandatory for dealing with government institutions, banks or currency exchange shops. A valid passport may also be accepted, but usually only for foreigners.
Brazilian identity card
The documents required to obtaining an identity card depend on whether the applicant is single, married or naturalized. Single people need a birth certificate (the original or a certified copy), while married people can use their marriage certificate, and naturalized people can use a naturalization certificate. An applicant's CPF number can be printed on the card alongside the RG number, if desired.
