If you are a Nigerian citizen, you may have heard about the recent directive from the federal government that requires all bank account holders to link their National Identification Number (NIN) to their bank accounts. This is part of the government's efforts to harmonize the identity management system in the country and improve security and service delivery.

But what is NIN and how can you link it to your bank account? In this blog post, we will answer these questions and guide you through the steps to complete this process.


What is NIN?

NIN stands for National Identification Number, which is a unique 11-digit number assigned to every Nigerian citizen by the National Identity Management Commission (NIMC). The NIN is used to verify your identity and access various government services, such as obtaining a passport, driver's license, voter's card, etc.


To get your NIN, you need to enroll at any of the NIMC enrollment centers across the country. You will need to provide some biometric and demographic information, such as your name, date of birth, address, fingerprints, etc. After enrollment, you will receive a slip with your NIN printed on it.


How to Link NIN to Your Bank Account

There are different ways to link your NIN to your bank account, depending on your bank and the channel you prefer. Some of the common methods are:


1. Via USSD Code
