For the security of your Nigerian bank account, the government introduced a unique BVN number for all citizens. This is why it is key to create your BVN number via your bank to avoid stories that touch with your hard-earned money. To sign up, simply head to your bank and ask them for the required form, fill it and you will receive your BVN number in no time.
If you wish to know your Bank Verification Number (BVN), you only have to dial 5650# to access the code immediately. No internet access is needed and you do not need to own a very expensive phone for confirmation. It can also be done on any SIM card.
To check your BVN code number online, through internet banking, just get yourself logged into your Internet banking app and the code will be visible on your screen.
That is that.
