Please note & stay safe

Belmadeng is an independent study platform and is not affiliated with NIBSS, the CBN or any bank. This is an informational guide — check, enrol or update your BVN only through official channels (your bank, the official NIBSS BVN validation portal, or the BVN helpdesk). Never share your BVN, OTP, PIN or card details with anyone, and never pay “agents” promising shortcuts.

Stay safe: your BVN, OTP and PIN are private. Never share them, and remember — knowing your BVN alone cannot move money from your account (that needs your card, OTP or a mandate you authorise).

Frequently asked questions

What is a BVN?

The Bank Verification Number — a unique 11-digit number tied to your fingerprints and photo that links all your bank accounts across every Nigerian bank. It was introduced by the CBN and NIBSS in 2014 to reduce fraud.

How do I check my BVN quickly?

Dial *565*0# from the phone number linked to your bank account (a small network fee applies), or check it in your bank’s mobile app or at a branch.

Do I need a separate BVN for each bank?

No — you have one BVN for life, and the same BVN is linked to all your accounts across every bank.

Is Belmadeng affiliated with the banks or NIBSS?

No — Belmadeng is an independent study platform. Use only official channels, and never share your BVN, OTP or PIN with anyone.
