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.

Most adults need the CURP code too, since it is required for almost all governmental paperwork like tax filings and passport applications. Most companies ask for a prospective employee's CURP, voting card, or passport rather than birth certificates.
