{{Main|Unique Population Registry Code}}
In Mexico, the ID number is called the [[Unique Population Registry Code|CURP (Clave Única de Registro de Población)]] although the most important and accepted ID card would be the [[Voting Credential|election card]] ("credencial de elector" or else "credencial del INE," as per the initials of Instituto Nacional Electoral (National Electoral Institute), the institution responsible for electoral procedures). There are, however, other important ID numbers in Mexico: for instance, the social security number, which is the number assigned by [[Instituto Mexicano del Seguro Social]] (Mexican Institute of Social Security, or IMSS) to every citizen who starts working, or the [[Federal Taxpayer Registry|RFC (Registro Federal del Contribuyente)]] which is assigned by the Treasury and has the same format as the CURP but a shorter length.
