| NIN Portal Issues Affecting SIM Registration in Nigeria: What You Need to Know |
Linking your National Identification Number (NIN) to your mobile SIM card is a mandatory requirement in Nigeria. However, many people face frustrating problems due to persistent NIN portal issues affecting SIM registration. If you’ve tried linking your NIN to MTN, Airtel, Glo, or 9mobile and received error messages or failed confirmation texts, this guide is for you.
In this article, we explore:
- Common issues with the NIMC portal
- How these issues affect SIM registration
- Ways to solve or work around them
- Tips for successful NIN-SIM linking
Why Linking Your NIN to SIM Is Mandatory
In 2020, the Nigerian Communications Commission (NCC), alongside the National Identity Management Commission (NIMC), made it compulsory for all citizens to link their NIN to their SIM cards to improve national security, reduce identity fraud, and centralize citizen records.
Failure to link your NIN can lead to:
- SIM card deactivation
- Inability to access mobile banking
- Blocked calls, messages, or mobile data
Common NIN Portal Issues Affecting SIM Registration
Several users have complained about delays and failures while trying to link their NIN. Below are the top portal-related issues:
1. NIMC Portal Downtime
- The NIN portal often goes down due to high traffic, poor server infrastructure, or technical maintenance.
- This prevents telcos from verifying your NIN during the SIM registration process.
2. Unverified or Incomplete NIN Data
- Many people submitted incomplete data during NIN enrollment (e.g., wrong date of birth, mismatched names).
- The NIMC portal rejects the NIN if the telco's records don’t match the NIMC database.
3. NIN-SIM Linking Delays
- Even after submitting your NIN, the linking process may take days or weeks due to system backlog or slow syncing between telcos and NIMC.
4. Failed OTP Verification
- Users are supposed to get OTPs (One-Time Passwords) when verifying NIN details.
- NIN portal glitches often prevent the OTP from being sent or accepted.
5. Multiple SIMs Linked to One NIN
- Users with multiple SIM cards sometimes exceed the limit of allowed NIN-SIM links.
- If you’ve reached your limit (typically 7 SIMs), your new attempt may be rejected.
How These Issues Affect You
If the NIN verification portal is down or your NIN details are incorrect, you may experience:
- “NIN does not exist” errors
- “Record not found in NIMC database”
- Network bars disappearing (SIM blocked)
- Inability to use mobile data or call
How to Solve NIN Portal Issues for SIM Linking
1. Confirm Your NIN is Valid
Use the NIMC Verification Portal or NIMC Mobile App to confirm your NIN is valid:
- Visit: https://nimc.gov.ng/verification-service
- Or download the “MWS: NIMC Mobile ID” app.
If the portal confirms your NIN is invalid or incomplete, visit a NIMC enrollment center.
2. Use USSD or Network-Specific Linking Codes
Try linking using the official shortcodes:
- MTN: Dial
*785#or send NIN to785 - Airtel: Dial
*121*1# - Glo: Dial
*109*NIN# - 9mobile: Dial
*200*8#
If the system responds with an error, retry after a few hours — portal access might be temporarily down.
3. Visit a Network Centre or NIMC Office
If you’ve tried everything online and it’s not working, take these steps:
-
Visit the nearest mobile network office with:
- Your SIM card (must be registered in your name)
- A valid NIN slip or printout
-
If the issue is from NIMC’s end (e.g., mismatched names or birth date), you’ll be directed to a NIMC office for data correction.
NIN-SIM Linking Delays: What to Do
If you linked your NIN successfully but the SIM is still blocked, try the following:
- Restart your phone and wait 24–48 hours.
- Contact your mobile provider’s customer care line and request a manual check.
- Use online linking portals provided by MTN, Airtel, Glo, or 9mobile.

Pro Tips
- Always double-check your name and date of birth on your NIN before linking.
- Try linking during off-peak hours (e.g., early morning or late evening).
- Use only official channels — avoid cybercafés or agents making unrealistic promises.
NIN portal issues can be frustrating, especially when they delay your SIM card reactivation or block essential services. However, knowing how the NIMC system works and using the right steps can save you time and stress.
By validating your NIN, correcting any errors, and using the correct USSD or mobile app methods, you’ll stay connected — and stay compliant.
