Many Nigerians misplace their NIN slip or simply forget their National Identification Number when they need it for bank verification, passport applications, SIM registration, JAMB registration, or other government services.

The National Identity Management Commission (NIMC) provides a USSD service that allows registered users to check and retrieve their National Identification Number without visiting an enrollment center. The service works on major networks including MTN, Airtel, Glo, and 9mobile. Recent information confirms that dialing *346# remains the official method for NIN retrieval on mobile devices.
If you have lost your NIN slip, changed phones, or simply need quick access to your identification number, this guide explains the exact steps to retrieve it using your phone.
