The clock is ticking for Nigerian mobile subscribers. The Nigerian Communications Commission (NCC) has been unwavering in its determination to achieve full compliance with the Federal Government’s directive on the National Identification Number (NIN)-Subscriber Identity Module (SIM) linkage. With the latest deadline extension to September 14, 2026, as announced by the NCC, millions of subscribers who have yet to complete the process are on notice. This is not just a bureaucratic exercise; it is a critical step in securing your identity and maintaining access to essential communication services.
This guide provides a comprehensive, step-by-step walkthrough to ensure every single one of your mobile numbers is successfully linked to your NIN before the final cut-off date. We will cover everything from official procedures to practical tips for managing multiple lines, helping you avoid the frustration of deactivation.
The 2026 Deadline Reality: Why You Must Act Now
The narrative around the NIN-SIM linkage has seen various deadlines come and go. The initial deadline was extended to April 6, 2026, in a move that gave subscribers more time to comply. However, the NCC has now set the final deadline for the end of this compliance exercise as September 14, 2026.
This date is significant. The NCC has made it clear that SIM cards not linked to their owners’ NINs by this deadline will be deactivated. Telcos have already begun blocking millions of phone lines from making and receiving calls as the previous deadlines approached, demonstrating that the regulatory body is serious about enforcement. The sale and purchase of pre-registered SIMs are also criminal offences, underscoring the importance of doing this process yourself and correctly.
There is also a security dimension. Fraudsters are known to use people’s data to register SIMs for other customers without their knowledge. By checking the numbers linked to your NIN and ensuring only your lines are attached, you can prevent acts of impersonation or the illegal use of your identity for fraudulent purposes. The time to act is now.
Verification First: Checking Your Current NIN-SIM Status
Before you start the linkage process, it is wise to first verify exactly how many mobile numbers are already linked to your NIN. This prevents you from unknowingly re-linking a line and helps you identify any numbers that may have been fraudulently registered under your identity.
The NCC has provided a simple USSD code for this purpose. Using the same SIM whose status you wish to check, dial the code *996# on any Nigerian network. You will then be presented with a menu. Select the option to view your NIN status, view numbers linked to your NIN, or view linked numbers.
The mobile numbers linked to your NIN will either be displayed on your screen immediately or sent to you via SMS. Take note of this list. If you see a number you do not recognise, it could be a sign of fraudulent activity. In that case, you should report it to your network provider and the relevant authorities. This verification step is your first line of defence in ensuring you only link your legitimate numbers.
Official Methods: How to Link Your NIN to Your SIM
There are several official channels approved by the NCC for linking your NIN to your mobile numbers. These methods are designed to be accessible whether you have a smartphone or a basic feature phone. The primary methods are via USSD codes, the NIMC mobile app, and through your network provider’s online portals.
The *996# USSD Code Method
The USSD code *996# is a universal code that works across all Nigerian networks. To use this method, dial *996# from the SIM you wish to link. Follow the on-screen prompts, which will include entering your 11-digit NIN.
Alternatively, for a more direct approach, you can dial *996*Your NIN# (for example, *996*12345678901#). This method submits your NIN directly for linkage with the SIM you are using.
The *346# NIMC Code
While *996# is the primary code for submission, *346# is the official NIMC USSD code for retrieving your NIN if you have forgotten it. This is a useful first step before proceeding with the linkage.
Network-Specific USSD and SMS Codes
Each mobile network provider has also created simple solutions, including shortcodes, to help you link your NIN to your SIMs. Here are the official codes for the major providers:
- MTN: DialÂ
*785#Â using the phone number you wish to link, enter your NIN, and submit. You can also dialÂ*785*Your NIN#Â from the phone number you wish to link. - Airtel: DialÂ
*121*1# on the Airtel line you wish to link. Select the option for NIN Capture, enter your NIN, and wait for a confirmation message. - Globacom (Glo): Send an SMS with “UPDATENIN NIN FirstName and LastName” to 109. For example, you would send “UPDATENIN 12345678912 John Doe” to 109.
- 9mobile: The process is done via their online self-service NIN update portal at www.9mobile.com.ng/NIN[citation:15].
The NIMC Mobile App Method
For smartphone users, the NIMC Personal Identity mobile application is arguably the most efficient method, especially if you have multiple phone numbers to link. The app can be downloaded from the Google Play Store or the Apple App Store.
After installing the app, launch it and input your 11-digit NIN to proceed. The app may require you to confirm your number using a one-time password (OTP) sent via SMS. If you do not receive an OTP, you can dial *364*2*NIN# to receive your UserID and OTP.
Once you are logged in, you will be taken to your identity platform, which displays your NIN information and picture. There will be an icon to link your numbers. Click on it and add the numbers you wish to link. An OTP will be sent to each number you are attempting to link; input this code, and the number will be successfully linked to your NIN.
What to Do if You Have More Than One Number
Having multiple phone lines is common in Nigeria, and the system is designed to accommodate this. Your unique NIN is your identity, and you are required to submit it to each of your different network providers to update your SIM records.
The process is simple: you must repeat the linkage process for each individual SIM card. If you have two MTN lines, you will use the MTN code *785# on each line. If you have lines on different networks, you will use the respective network-specific code for each line.
Using the NIMC mobile app can simplify this process, as it allows you to link up to 28 mobile numbers in one go, provided they are not all on the same network. The app facilitates the process by sending OTPs to each number for verification.
After Successful Linkage: Confirmation and Final Steps
Once you have submitted your NIN via any of the approved channels, your mobile network provider will validate the submitted NIN against the NIMC database. If the validation is successful, your SIM will be linked.
You should receive a confirmation message from your network provider. This message is your proof of compliance. Keep it for your records. If you do not receive a confirmation, or if you receive an error message, wait a while and try again. Ensure you are entering the correct 11-digit NIN. If problems persist, contact your network provider’s customer service directly.
Remember, the final deadline is September 14, 2026. Do not wait until the last minute. There will likely be a surge in traffic, potentially causing delays or system errors. Acting proactively is the only way to ensure your lines remain active and your identity remains secure. The NCC’s directive is clear: by the end of this compliance exercise, SIMs without NINs will no longer work.
