What is NIN and Why is it Important?

The National Identification Number (NIN) is a unique 11-digit number issued by the Nigerian government to citizens and legal residents. It serves as a means of verification and identification. Linking your NIN to your bank account helps:

  • Comply with government regulations

What is a Virtual NIN (vNIN)?

A Virtual NIN (VNIN) is a temporary, tokenized version of your actual NIN. It provides an extra layer of privacy protection when verifying your identity with organizations like banks. You can generate a VNIN using the NIMC mobile app or a USSD code (*3463*Your NINAgentCode#)
