Nigeria is a country that continues to grow in population and in turn, increases the number of active mobile subscribers in the country. But having an identification number that enables you to use mobile networks effectively is important. This is why Airtel subscribers need to know how to link NIN to an Airtel line to avoid disconnection from the Nigerian Communications Commission (NCC).

In the last decade, there has been a call for Nigerians to register and get captured in the country’s identification portal. This exercise entails the data capture of every mobile Nigerian. Therefore, it becomes necessary because your identity registration precedes getting an identification number – the NIN.

Link NIN to Airtel line

NIN (National Identification Number) is the unique 11-digit number that characterises the identity of a registered Nigerian. This means that NIN can be used to track the identity of a Nigerian. Therefore, this can be likened to the unique alphanumeric code on your international passport, which represents and can be traced to you.

How To Get An NIN Code

You must think of having a NIN code before you decide to link your NIN to your Airtel line. Therefore, the following are the steps to obtaining your NIN:

  • Visit any NIMC registration centre closest to you
  • Request for a pre-enrolment slip
  • Enter your details. This includes your full name, date of birth, state of origin, mother’s maiden name, etc
  • Submit your application
  • Wait to get your tracking number
  • Go back after a few weeks to collect the slip that has your NIN on it

Understanding The NIN Code For Airtel

In recent times, the mobile networks in Nigeria have been working in synergy with the NCC to ensure the compliance of active mobile subscribers to register to get a NIN code. This is evident in the phases of disconnection some unregistered Nigerians have gone through. It is owed to the fact that you are expected to register for the NIN code and link the NIN to your mobile number to enable you to activate the use of the phone number.

Airtel is one of the network giants in Nigeria, with tens of millions of mobile subscribers. Therefore, Airtel is working in sync with the directive of the NCC to ensure absolute compliance of its users to having a NIN code and linking their NIN to their respective Airtel line. As such, your Airtel phone number stands the risk of disconnection if you do not link your NIN to your Airtel line.

Your access to Airtel service becomes limited when your Airtel line is disconnected. This would prevent you from buying airtime to call or text. It can even disconnect you from using the line for internet access.

Broadly, the link of NIN to Airtel lines has been able to ascertain the number of active subscribers for the mobile network. At the same time, it has reduced the chances of unscrupulous individuals serving as a threat in identity theft. So once you link NIN to your Airtel line, your phone number indicates your personal information, especially your full name and address.
