The commission oversees the registration and distribution of the National Identification Number (NIN), issues National e-ID card s, conducts identity verification, and ensures the harmonization and authentication of user data. The
national identification number is a part of Nigeria's National Identity Management System, the other part is the General Multi-Purpose Card. The number stores an individual's unique data into the database. It is part of a measure to create a national identity database and to prevent both double identity and
identity fraud. The NIMC self-service portal allows users to modify their National Identification Number (
NIN) details online. This includes changes to date of birth, name, address, email, and phone number. The portal provides a secure and user-friendly process, requiring specific documents for each type of modification. In July 2024, the offices of
MTN,
Glo and others were stormed nationwide by subscribers after the telecoms deactivated lines not linked with a NIN. One month later, the NCC announced a new September 14, 2024 deadline for individual linking of NINs to SIM cards. ==Identity card==
