What is NIN?

NIN stands for National Identification Number, and it is a set of unique numbers allocated to every Nigerian citizen who has enrolled for the NIN registration.


The enrollment process involves biometrics which has to do with the capturing of the individual’s demographic data and ten fingerprints, headshot, and digital signatures which are used to cross-check already existing data in the NID (National Identity Database) to affirm that their has been no previous entry of similar data.

As soon as this (deduplication) process is completed, the data is stored with a distinct NIN assigned to it. Once issued to a person, the NIN cannot be reused (i.e., the string of numbers cannot be issued to another person even if the previous owner is dead). It is the NIN that helps to link all records of a person in the database and is used to verify his or her identity.

Guidelines for NIN Registration

How To Know If My Line is Linked to NIN

The National Identification Number (NIN) consists of a string of 11 unique numbers that are selected at random and assigned to an individual upon completion of registration in the National Identity Database (NIDB). Once a NIN has been assigned to an individual, it can never be reassigned, given, or used by another person – this is what makes them unique in nature.

In the event of a person’s death, their NIN will be retired as soon as a death certificate is presented and issued to the family of the deceased. The NIN is used to link all records of a person in the database and is also used to establish or verify their identity.


All citizens and individuals legally resident in Nigeria from age zero (birth) and above are eligible to enroll for their NINs. The NIN should be closely guarded and kept confidential by the owners and should never be disclosed to everyone except when requested by the banks, government, law enforcement agencies, and other relevant authorities in the country.

In the same vein, the NIN should never be revealed on the internet or social media platforms and should not be one of the contact details printed on business cards and other office stationery.

Eligibility and Requirements For NIN Registration

It is compulsory for every citizen and every legal resident to register for the National Identification Number (NIN). The process is the same whether you choose self-service or need assisted service.  Minors do not receive an identity card until they have reached the mature age of 16.
