Last updated on May 15th, 2024 at 03:11 am


There have been a lot of changes in how to change your name, modify your date of birth, change of address, and update of your phone number on your NIN data since the National Identity Management Commission (NIMC) launched its self-service modification portal.

Date of birth

The documents you will need to have the correct date of birth on your NIN are:

  • Digitalize NPC attestation certificate (if you were born before 1992)
  • Digitalize NPC birth certificate (if you’re born after 1992)
  • You can apply for NPC attestation and birth certificate on the National Population Commission website or check our guide on how to obtain a birth attestation certificate online on NPC portal.

Change of phone number


Don’t add a zero to your phone number if you’re using the international dialling code (+234) to prevent double zeros in front of your phone number.


  • Correct: +2348067024054
  • Wrong: +23408067024054

If you use the wrong sample, you will most likely have 008067024054, which will return as an error or lead to the invalidation of your data.

Instead of going this route, it is better to retrieve your phone number at any of the branch offices of your telecom provider. Although you will also need a police report, which is not free, you will not have to pay your telecom provider to get this done.

Going through the NIN route will make you pay for a police report and also pay for change of number on the NIMC self-service portal.

Change of address

If you’re in a rented apartment, it’s better to use your permanent home address in your home town. In case you still want to change the address on your NIN, here are the documents required:

  • Utility Bill. You can download a copy of your power bill.
  • Tenancy Agreement
  • Attestation letter from your community leader
