Linking your NIN is mandatory for all Nigerian mobile users to avoid service restrictions, including outright barring of your line. Completing this process secures your SIM and ensures uninterrupted calls, data, and SMS services on the MTN network.
You will learn the exact requirements, the step-by-step process using USSD code *785#, the costs involved, and what to do if you encounter issues. This guide provides everything you need to successfully link your NIN to your MTN line in minutes.
What You Need to Link NIN to MTN
Before you start, ensure you have the following items ready to complete the process smoothly.
- Your 11-digit NIN: This is found on your NIN slip or NIMC ID card. If you don’t have it, dial *346# on any line to retrieve it.
- The active MTN SIM card: The specific line you wish to link must be in the phone you are using and have sufficient network signal.
- A mobile phone: Any basic or smartphone that can make USSD requests. Ensure it is charged.
- Cost: The linking service via USSD is free of charge. No airtime will be deducted for the process.
- Optional – Valid ID: If visiting an MTN service center, bring a valid government-issued ID (Driver’s License, International Passport, Voter’s Card).
The entire process takes less than 5 minutes if you have your NIN handy. If you need to retrieve your NIN first, add an extra 2-3 minutes.
How to Link NIN to MTN SIM Card: Step-by-Step Instructions
Follow these steps to link your NIN to your MTN line in minutes using the official USSD method.
Step 1: Dial the Official USSD Code
On the phone containing your active MTN SIM, open your dialer and enter *785*Your 11-digit NIN#. For example, if your NIN is 12345678901, you will dial *785*12345678901# and press the call button.
This is the primary and fastest method. The service is free, and you do not need airtime on your line for it to work. A menu will load on your screen.
Step 2: Confirm Your Details
The screen will display your name as registered with NIMC. Carefully review the name to ensure it matches your official records. This is a crucial verification step.
If the name is correct, you will proceed. If it is incorrect, do not proceed. You will need to visit an NIMC office to correct your data first.
Step 3: Submit Your Request
After confirming your name, follow the on-screen prompt to submit your request. This is usually done by replying with a specific number like 1 or selecting a “Send” option.
Your request is now sent to MTN for processing. Do not interrupt the process or turn off your phone at this stage.
Step 4: Wait for Confirmation SMS
Wait for a system-generated SMS from MTN (often from “MTN NIN”). This message confirms your submission was received. It may state that your request is being processed.
This first SMS typically arrives within 1-2 minutes. It does not mean the linking is complete; it is an acknowledgment.
Step 5: Receive Final Success Notification
Within 24 to 48 hours, you will receive a second, final SMS confirming your NIN has been successfully linked to your MTN number. The message will read something like, “Dear Customer, your NIN has been successfully linked.”
Save this SMS as your proof of compliance. Your line is now secure and will not be barred for NIN-SIM linkage issues.
Step 6: Verify Your Linkage Status
To double-check, dial *785# again. If your NIN is linked, you will see a notification confirming the linkage on your screen.
Alternatively, you can visit an MTN service center with your phone and ID for them to confirm the status on their system.
Alternative Step: Visit an MTN Service Center
If the USSD method fails, visit any MTN service center or an authorized agent. Go with your phone, original NIN slip, and a valid photo ID.
An agent will assist you. The service is free at official centers. Centers are open Monday-Friday, 8:30 AM – 5:00 PM, and Saturdays 9:00 AM – 3:00 PM in major cities like Lagos, Abuja, and Port Harcourt.
Step 7: What to Do If You Encounter Errors
If you get an error like “NIN not found,” your details may not be fully synced on the NIMC database. Wait 24 hours and try the USSD code again.
If errors persist after 48 hours, visit the nearest NIMC Enrolment Center to verify and update your data. Then, restart the linking process.
Other Ways to Link Your NIN to MTN
If the USSD method fails or you prefer a different approach, use these reliable alternatives.
Method 2: Use the MyMTN App
This method requires a smartphone and internet data. Download the “MyMTN” app from Google Play Store or Apple App Store. Log in with your MTN number, navigate to the services section, and look for the “NIN Linkage” or “SIM Registration” option. Enter your 11-digit NIN when prompted and submit.
This method provides a visual interface and is good for keeping a record. You will receive the same confirmation SMS as the USSD method within 24-48 hours.
Method 3: Visit an MTN Service Center or Authorized Agent
This is the best alternative if you face persistent errors or are not tech-savvy. Walk into any official MTN service center or an authorized dealer/agent shop. Present your physical NIN slip or NIN ID card and a valid government-issued photo ID (Voter’s Card, Driver’s License, International Passport). The agent will process the linkage for you on the spot.
This is the most reliable method for resolving issues, though it requires physical movement. Ensure you go to an official outlet to avoid being charged.

Important Tips and Advice
Follow these practical tips to ensure a smooth and successful NIN linking process:
- Timing is Key: Perform the USSD linkage (*785#) during off-peak hours, ideally between 10:00 AM and 4:00 PM on weekdays, to avoid network congestion that can cause errors.
- Double-Check Your NIN: Verify your 11-digit NIN by dialing *346# before starting. Entering an incorrect NIN is the most common cause of failure and delays.
- Save All Proof: Do not delete the final confirmation SMS from MTN. Take a screenshot and save it as your proof of compliance in case of future disputes.
- Prepare for Physical Visits: If going to a service center, arrive by 8:30 AM, bring a power bank for your phone, and carry a bottle of water, especially in Lagos, Abuja, or Port Harcourt where queues can be long.
- Have a Backup Plan: If the USSD fails after 3 attempts, switch methods. Use the MyMTN app with a stable Wi-Fi connection or proceed directly to an authorized agent to save time.
Common Problems and Solutions
Here’s how to fix the most common issues encountered when linking your NIN to MTN:
Problem 1: “Transaction Failed” or USSD Not Responding
Solution: This is often due to network congestion. Wait 15-30 minutes and try again, preferably between 10:00 AM and 2:00 PM. Ensure you have at least two signal bars. If it persists, restart your phone.
Problem 2: “Invalid NIN” or “NIN Not Found” Error
Solution: Double-check you entered the correct 11-digit number from your slip. If correct, your NIMC data may not be fully synced. Wait 24 hours and try again. If the error remains, visit an NIMC office for data verification.
Problem 3: No Confirmation SMS After 48 Hours
Solution: First, verify your linkage status by dialing *785#. If it shows as unlinked, repeat the process. Also, check your SMS spam folder. If still unresolved, your submission may have failed silently and needs to be redone.
Problem 4: Name Mismatch on USSD Screen
Solution: Do not proceed if the displayed name is wrong. This means your NIN record contains errors. You must visit an NIMC Enrolment Centre to officially correct your data first before attempting to link your SIM.

If problems persist after trying these solutions, contact official support:
- MTN Customer Care: Dial 180 (toll-free from your MTN line).
- Visit an MTN Service Center: Find your nearest one via the MyMTN app or website.
- NIMC Support: Call 0700-CALL-NIMC (0700 2255 6462) for NIN-related data issues.
