The Iranian identity card is the primary identity document in Iran. Every citizen age of 15 and above, whether resident or not, needs to apply for such a card, which bears their unique national identity number, given name, surname, birth date, and postal code. The current version of this card is called the national smart card and is the successor of the national card. This card is intended to reduce the need for the more valuable Iranian identity booklet, which is issued at birth.
