How Many Digits is a BVN in Nigeria?
The BVN in Nigeria is always an 11‑digit number.
It is unique to every individual, and no two people share the same BVN, even if they have accounts at the same bank.
Example format: 22345678901 (for illustration purposes).
Every time you open a bank account in Nigeria, you are required to enroll for a BVN (if you don’t already have one). This biometric system was introduced by the Central Bank of Nigeria (CBN) to curb fraud and improve security across the banking sector.
Why 11 Digits?
The BVN is designed to fit into a national database with room for over 99 billion unique numbers, enough to cover Nigeria’s population and beyond.
Each digit is generated to uniquely identify your biometric data (fingerprints, facial image, signature) securely across all banks.
Why Knowing the Length of BVN is Important
Many people wonder why it even matters to know that BVN is 11 digits. Here are some reasons why:
1 To Avoid Fraud
There are scammers who send fake messages or emails asking you to “verify” your BVN. They sometimes send you incorrect BVN formats as a trap.
If you know your BVN must always be 11 digits, you can instantly spot a fake.
2 For Proper Verification
When filling online forms for loans, banking apps, government schemes (like NYIF, NIRSAL, TraderMoni), you will always be asked for your BVN.
If you mistakenly enter 10 or 12 digits, the system will reject your request.
3 To Verify Your Identity Across Banks
Because your BVN is linked to all your bank accounts, knowing the exact 11‑digit number ensures you can verify your identity seamlessly, even if you open a new account at a different bank.
Common BVN Mistakes to Avoid
Using the wrong number of digits (less or more than 11).
Giving your BVN to strangers or agents unnecessarily.
Forgetting which phone line is linked to your BVN.
Not updating your BVN details (like phone number) when you change SIMs.
Your BVN is more than just a number — it is your unique financial identity in Nigeria. Always remember:
Your BVN is exactly 11 digits.
Never share it publicly.
If anyone gives you a BVN shorter or longer than 11, it is fake.
If you forget your BVN, you can easily retrieve it with the code *565*0# or via your banking app.
