The Federal Government of Nigeria through its Communications Commission issued a directive for all Nigerians to link their NIN to their SIM cards.

The FG gave a timeline and a deadline for the Nigerian Communications Commission (NCC) to do this. However, many Nigerians did not comply till the deadline. The NCC had to extend the deadline by several months. Yet, that was not enough for Nigerians to do the needful.

So the government had to follow this extension of deadline by about 8 other extensions before implementing the deadline.

On the final deadline, that is March 31, 2022 opportunity to use SIM cards without linking to NIN was over.

The government gave strict orders to Telecommunication Operators to bar outgoing calls for subscribers who are yet to link their line to NIN.

Therefore, on Tuesday, April 5, 2022, the Association of Licensed Telecommunication Operators of Nigeria began implementation of the orders.

Consequently, hundreds of thousands of Nigerians who did not link their SIM cards to NIN lost the ability to make outgoing calls with their phones. However, they could still receive calls and send text messages.

So you can get your 11-digit NIN at no cost using the steps below.

1. Dial *346# from the phone number associated with your voter’s card, driver’s licence, or BVN registration.
