For now, Glo and 9Mobile have not commenced sim linking with NIN. As soon as they commence, we will update this post to reflect the steps you must follow to carry out the linking.
However, to get yourself ready to be able to carry out the linking of your NIN with your phone number here’s what you must do:
Visit any NIMC office near you and apply for your National Identity Card if you haven’t
Register and obtain your temporary ID slip which will contain your NIN
Keep your NIN details in a safe place so that you’ll be able to provide them when necessary.
What if you forgot your NIN and don’t have the slip?
If you don’t know your NIN, just dial *346# on the SIM card you registered with the National Identity Management Centre (NIMC).
A message containing your NIN will be displayed, just copy it somewhere safe.
Note that checking your NIN via the USSD provided above costs N20 only.
