Bank verification number aka BVN is a biometric identification system that is integrated by Central bank of Nigeria to reduce illegal banking transaction in Nigeria. However, this is a modern security measure that is in line with the CBN Decree which helps reduce fraud in the country.
Recently, I was trying to make an order online, and it was denied, only for me to find out that I was locked out from internet banking and all other related transactions. My bank account was temporary locked out. I was a bit confused only to find out that my BVN was not linked to my bank account.
