In the Republic of South Africa every citizen must apply for an Identity Document from the age of 16 years. The ID number is already allocated at the time the birth certificate is generated and required for child passport applications. This passport-size document contains only 8 pages - the first page containing the national identification number (also in barcoded format), name of bearer, district or country of birth, as well as a photograph of the bearer. The other pages are used for recording of voting participation, a page for driver's license information (although it is no longer used since the introduction of plastic card type licenses), as well as pages for fire arms licenses (also plastic card type now). The document is required to apply for a passport, car learner's license (over 17), motorcycle learner's license (over 16), driving license (over 18), motorcycle license (over 16 or 18 depending on cc) and to vote (over 18). The Identity Document is not used for international travel purposes (a separate passport is issued) but usually is acceptable photographic identification for internal flights, and mainly serves as proof of identification. Some authorities may accept the driver's license as proof of identity, but the Identity Document is the only universally accepted form of identification. The government has started issuing ID cards which contains a biometric chip which, in turn, holds biographical information which is unique to the holder of that specific card. The South African government wishes to phase out the old Green Barcoded ID book and replace it with the Identity Card. The Identity number is also used when the holder applies for a grant from the South African Social Security Agency (SASSA).
