The Federal Government has directed that all SIM cards be linked to a National Identification Number (NIN). Failure to do so will result in a blockage. To keep your 9mobile sim from being blocked, we’ve created this post to educate you on the various methods you can use to link your NIN to your 9mobile sim.

NIN stands for National Identification Number, which I’m sure you already know. It is a unique 11-digit number, and everyone should have one.
If you haven’t yet registered for your NIN, you can do so at any NIMC Enrolment Centres or at your preferred mobile operator center. If you’ve registered or had a NIN in the past but can’t quite remember it, dial *346# on your 9mobile phone to get your NIN right away.
How to link NIN to your 9mobile line
- On your phone, dial *996#.
- If your NIN has been successfully linked to your phone number, dial 1 to confirm.
- To link your 11-digit NIN, dial 2.
