NIN to SIM Linkage for all Mobile Networks

For Citizens who have the National Identification Number (NIN) and also are subscribed to any of the various mobile phone networks in Nigeria, Follow the steps below to link your SIM card with the 11 digits National Identification Number (NIN) i.e. NIN to SIM linkage.

But before you start, take note of the following:

  • Firstly, those with the National Identity Card issued by NIMC, sorry to tell you that the 11-digit identification number is not printed on it. The NIN is meant to be confidential; you have to search for the National Identification Number Slip (NINS) issued to you on the day you registered to get the NIN number;
  • Secondly, If you have misplaced the National Identification Number Slip (NINS), there is hope! Use the USSD code *346# to retrieve your NIN from NIMC at no cost as directed by the Federal Government.
  • Lastly, the National Identification Number (NIN) submitted through the various platforms provided by all mobile network operators will be received as unverified, pending validation on NIMC database. If not successfully validated, you may be required to re-validate this information in person in the office of your network provider.

In Conclusion, after your NIN (11-digit number) has been submitted, the network provider will begin the process of verification with the NIMC. If your NIN is verified, congratulations! It will further be linked to your network SIM registration, so you may not need to do anything. But if it is not possible to verify the NIN you have submitted, then you may need to visit a NIN enrolment center, in person.

Failure to either submit your NIN (11-digit number) to your network operator for verification and linkage or go to the NIN registration center to get a National Identification Number (NIN) before 19th January 2021 or 9th February 2021 respectively will lead to the blocking of the subscriber line as directed by the Nigerian Communication Commission (NCC).

For Nigerians in diaspora, visit NIMC for details of diaspora enrolment and to learn more on the National Identification number, read the article “NIM registration and linkage with SIM“.
