A national identification number, national identity number, or national insurance number is used by the governments of many countries as a means of tracking their citizens, permanent residents, and temporary residents for the purposes of work, taxation, government benefits, health care, and other governmentally-related functions. The number appears on identity documents issued by several countries.

Director-General of the National Identity Management Commission (NIMC), Engr. Aliyu Aziz, had at a press conference in Lagos, warned that any Nigerian without the National Identification Number (NIN) issued by the commission runs the risk of being regarded as a non-Nigerian citizen.

At NIGTEL-CS, you will be guided through on how to get your NIN, this is because it is compulsory for every Nigerian citizen to acquire his/her own.
