Quick answer

Dial *996# on any Nigerian network and follow the prompts, or dial *996*YourNIN# to submit it in one step. MTN also accepts *996*1#. Linking is free. If you do not know your NIN, dial *346# from the number you registered with NIMC.

Linking your NIN, step by step

01

Have your NIN ready

The 11-digit number is on your NIN slip or in the NIMC app. If you have lost it, dial *346# from the number you registered with NIMC (a small NIMC charge may apply), or *996*3# on an MTN line.

02

Dial *996# on any network

The NCC's harmonised code *996# works on MTN, Airtel, Glo and 9mobile. Follow the prompts, or dial *996*YourNIN# to submit the number in one step.

03

Or use your network's own route

MTN: dial *996*1# and enter your NIN, or use the MTN NIN linking website. Airtel: dial *996# to check your status; the NCC's FAQ lists *121*1# (NIN Capture) for linking, so confirm on Airtel's site or in an Airtel shop. Glo: dial *996# to check the link status, and complete the linking at a Glo outlet. 9mobile: check 9mobile's website or an outlet; we could not load its site when we checked.

04

Wait for the confirmation message

Your network checks the NIN with NIMC. You get an SMS when the link succeeds or if more details are needed.

05

Check the status later

Dial *996# again on any network to see whether the line is linked. MTN also has a NIN status page on its website.

Why the link matters

The Nigerian Communications Commission requires every active line to be tied to a verified NIN, and a line without one can be barred from the network until the link is done. The NCC also warns subscribers never to let their NIN be linked to another person's SIM, no matter how close the person is, because the line's activity is then recorded against you.

Only channels published by your network, NIMC or the NCC are genuine. Nobody needs your NIN by WhatsApp or a web form sent in a chat.

If you also hold crypto

A linked SIM keeps your bank alerts and one-time codes flowing, which matters the day you move money. If some of that money is in crypto, Yesa sells USDT, Bitcoin and other coins for naira straight to your bank account, with the exact naira figure on screen before you confirm and zero sell fees. Across 1,700 measured bank payouts on Yesa, the median payout time was 4.7 seconds. These are historical measurements, not guarantees. The on-chain part, your crypto reaching Yesa, comes first and depends on the network you send on.

Linking NIN to SIM: common questions

What is the USSD code to link NIN to SIM?

*996# on any network, or *996*YourNIN# to submit it directly. MTN also publishes *996*1#, and the NCC lists *121*1# for Airtel.

How do I check whether my NIN is linked?

Dial *996# on the line. The reply says whether a NIN is linked. MTN also has a NIN status page on its website.

Is linking NIN to SIM free?

Yes. The NCC states that the linkage of SIM to NIN is free. *346# may carry a small NIMC charge; the NCC said it was waived during the 2020 to 2021 update exercise. On MTN you can also retrieve your NIN by dialling *996*3#.

I do not know my NIN. What do I do?

Dial *346# from the phone number you registered with NIMC and choose NIN retrieval. If you were never enrolled, visit a NIMC enrolment centre; the networks cannot create a NIN for you.

How long does the link take?

The network checks your NIN with NIMC and texts you the result, or asks for more details if the check does not go through.

Can I link one NIN to several SIMs?

Yes, a NIN can be linked to more than one line in your name. The NCC's warning is the reverse: never let your NIN be linked to a SIM that someone else uses.
