Why do I need to link my NIN to my MTN SIM?
The Nigerian Communications Commission (NCC) requires every active SIM in Nigeria to have a National Identification Number (NIN) linked to it, across MTN, Airtel, Glo, and 9mobile alike. This is a national identity and security policy, not something MTN introduced on its own — MTN, like every network operator, is required to enforce it. The NCC's own consumer-facing materials describe this as an ongoing, mandatory requirement into 2026, applying to both existing lines and newly registered SIMs.
How do I link my NIN to MTN using *996#?
- Dial *996# and press call.
- Select the option to submit your NIN (menu wording is typically along the lines of "Submit NIN").
- Enter your 11-digit NIN exactly as it appears on your NIN slip or National ID card.
- Confirm submission. You should receive an on-screen or SMS confirmation that the number has been received for processing.
*996# is described in NCC-related guidance as a short code intended to work uniformly across all Nigerian networks, not an MTN-specific code — so the same code is expected to route correctly regardless of which network's SIM is dialing it.
Can I link my NIN online instead?
Yes. MTN Nigeria operates a dedicated NIN linking portal, accessible from MTN's own website, where you can enter your NIN and phone number without needing to dial a USSD code. The myMTN app offers an equivalent option, typically under an account or identity-verification menu. Either route submits the same information as the *996# method.
What happens if I don't link my NIN?
The NCC's rules treat unlinked lines as non-compliant, and in past enforcement rounds this has led to restrictions — barred outgoing calls first, followed by full deactivation for lines that remained unlinked past a published cutoff. A deadline from September 2024 is the most recent one this research could confirm; NCC materials describe linkage as an ongoing mandatory requirement through 2026, but this research could not confirm whether a new, currently-active enforcement cutoff date exists right now. Rather than waiting to find out, link your NIN as soon as possible — there's no downside to doing it early, and every method above is free.
How do I check if my NIN is already linked?
MTN's NIN status portal, reachable from MTN's website, lets you check your current linkage status by entering your phone number. You can also dial *996# and look for a status-check option within the menu, though the exact wording of that option could not be independently confirmed in this research pass.
What if my NIN and SIM registration details don't match?
Linkage can fail or get flagged if the name, date of birth, or other identity details on your NIN record don't match what was captured when your SIM was originally registered. In that case, submitting the NIN through *996# or the portal alone may not resolve it — you're likely to need an in-person visit to an MTN store with a valid ID matching your NIN details, so the mismatch can be corrected on MTN's side. This detail is based on how identity-mismatch cases are generally handled across Nigerian NIN-SIM linkage, and wasn't independently confirmed against an MTN-specific process description in this research pass, so treat it as a likely-but-unconfirmed path rather than a guaranteed fix.
People also ask
Is linking NIN to MTN free?
Yes. Neither the *996# USSD session nor the online portal charges a fee to submit or link your NIN.
Do I need to link my NIN separately for each SIM I own?
Yes. NIN-SIM linkage is done per SIM, so if you have more than one active MTN line, each one needs to be linked individually.
What if I don't have a NIN yet?
You'll need to register for a NIN through the National Identity Management Commission (NIMC) first, since NIN-SIM linkage requires an existing, valid NIN to submit. This page does not cover NIN registration itself.
