A National Identification Number is a means governments around the world use to track their citizens, permanent residents, and temporary residents for the purposes of security, health care, taxation, government benefits, and other tracking-related functions to simplify government works and functions.

Understanding National Identification Number by country

Countries around the world call their National Identification Number (NIN) by different names, in some, such as Australia use means of proof to identify its citizens.

National Insurance Number, Social Security Number, Unique Master Citizen Number, and Personal Identification Number of Citizen or JMBG/EMBG are some of the names some jurisdictions use to identify their citizens.


The implementation of means of ID varies from country to country, in most cases, countries issue means of ID to their citizens upon reaching legal age or at birth.

This means of identification isn’t designed only for citizens of country, there is inter-connectivity between countries. Canadian citizens travel to the United Kingdom, and United States citizens travel to Australia, as such, non-citizens may be issued some unique numbers or permanent residence permit when they enter a country other than their own.


After several attempts to have a database for its citizens, the most populous African country launched its National Identification Number in May 2007, by establishing a separate agency National Identity Management Commission (NIMC) to manage the identification of Nigerians.
