How to Link NIN to MTN Number in Nigeria 2023

Learning how to link NIN to MTN or any other line in Nigeria has become so important and popular. Especially as the Nigerian Communications Commission (NCC) has threatened many times to block phone lines not paired with NIN Number.

Before we get into how to link your NIN to MTN in Nigeria and synchronise your SIMs, here are a few things to note.

The National Identification Number or NIN is a government-issued unique identification number used to identify Nigerians. NIN is issued by NIMC – the government agency responsible for identity management in Nigeria.

NIN is a core component of Nigeria’s National Identity Database, it essentially maps you your biometric data and some other details.

Most importantly, NIN is used for verification and authentication.

When you link NIN to MTN or any other line, it is only connecting to your phone number, it doesn’t have anything to do with your bank account.

The NCC directive to link NIN to MTN line and other telco lines applies to all citizens or anyone who has a Nigerian SIM or mobile line. So you have to enrol for your NIN yourself as It is a personal Identity Number for you.
