In [[Spain]], all resident Spanish citizens can obtain (mandatorily after 14&nbsp;years old)<ref name=spaindni>{{cite web|title=DNI - Concepto y validez|url=http://www.interior.gob.es/web/servicios-al-ciudadano/dni/concepto-y-validez|website=Ministerio del Interior|access-date=18 September 2015|archive-date=21 February 2017|archive-url=https://web.archive.org/web/20170221031557/http://www.interior.gob.es/web/servicios-al-ciudadano/dni/concepto-y-validez|url-status=dead}}</ref> a ''[[Documento Nacional de Identidad (Spain)|National Identity Document]]'' (Spanish: ''Documento Nacional de Identidad'' (DNI)), with a unique number, in the format 00000000-A, where 0 is a digit and A is a [[checksum]] letter. Since 2010, foreign residents are no longer issued with identity cards, although they are assigned a number in the format X-0000000-A (again, 0 is a digit, A is a checksum letter, and X is a letter, generally X but lately also Y), called an [[NIE Number]] (''Número de Identificación de Extranjeros'', Foreigner's Identification Number). The DNI is required for all transactions related with tax authority, as well as to access the ubiquitous [[Spanish National Health System]] (although it has its own insured identification document), apply for marriage licences, receive unemployment compensation, and in general all interactions with law enforcement and any government or government-supervised institution.

Foreign residents are required to use their passports together with the document containing their NIE number
