Editing National identification number (section)

=== Colombia ===
In [[Colombia]], each person is issued a basic ID card during childhood (''Tarjeta de Identidad''). The ID number includes the date of birth and a short serial number. Upon reaching the age of 18, every citizen is reissued a citizenship card (''Cédula de Ciudadanía''), and the ID number on it is used and required in all instances, public and private.

Every Colombian national traveling abroad is issued a passport document (which includes a passport number related to the national identification number); in this manner foreign governments can track Colombian nationals with their consulates.

There is as well a number assigned to companies: NIT (''Número de Identificación Tributaria''). Tributary Identification Number (for its Spanish acronym). Among other things, it is used for tax reports.

RUT (''Registro único tributario'') (taxpayer identification number)
