Also in other pages of the Shenasnameh Marriage status, Spouse(s) name(s), Children names, Date of every vote they give and also their death would be registered.[16]
Every Iranian permanent resident above the age of 15 must hold a valid National Identity Card (Persian:کارت ملی) or at least obtain their unique National Number from any of the local Vital Records branches of the Iranian Ministry of Interior.[17]
In order to apply for an NID card, the applicant must be at least 15 years old and have a photograph attached to their Birth Certificate, which is undertaken by the Vital Records branch.
Since June 21, 2008, NID cards have been compulsory for many things in Iran and Iranian Missions abroad (e.g., obtaining a passport, driver's license, any banking procedure,etc.)[18]
