How to check if your NIN
is linked to your SIM
card
Before we show you how to link NIN
to SIM card for all networks, let’s first
take you through how to check if your
SIM card is connected with NIN
already.
The process to check this is by dialing
the USSD code 346#, and the eleven-
digit number will appear on your
screen. 346# can be used for all
networks.

<ins class="adsbygoogle" style="display:inline-block;width:336px;height:280px" data-full-width-responsive="true" data-ad-client="ca-pub-2676590700924448" data-ad-slot="5270264218"></ins>

You can only see the unique number
if your NIN is linked to the particular
line (SIM Card) you dialled it with.
All mobile phone users are hereby
advised to confirm if their NIN is
linked with their line by following the
procedures above.
