| How Many Digits Is NIN |
Are you wondering how many digits your NIN has or trying to verify if your NIN is correct? This guide explains everything you need to know about the structure, length, and importance of the NIN (National Identification Number) in Nigeria.
What Is the NIN?
The NIN stands for National Identification Number. It is a unique 11-digit number issued to every Nigerian citizen and legal resident by the National Identity Management Commission (NIMC) after successful enrollment.
It is your permanent identification number, used for:
- Government and banking services
- SIM registration and linkage
- JAMB, NYSC, WAEC, and NECO processes
- International passport applications
- Tax and health records
- Identity verification across platforms
So, How Many Digits Is the NIN?
Your NIN is exactly 11 digits long. No more, no less.
Example:
A typical NIN looks like this:
12345678901
Every NIN is unique to an individual — no two people share the same number.
Why 11 Digits?
The 11-digit format allows NIMC to assign:
- Over 90 billion possible combinations
- Enough room for all Nigerians and future generations
- Security and uniqueness per user
- Easy use across mobile and online systems
Fun fact: With 11 digits, the NIMC can register over 99 billion people, far more than Nigeria's population.
How to Verify If Your NIN Is Valid
If you're unsure whether your NIN is correct or complete:
Option 1: Dial USSD Code
- Dial
*346#on your registered phone line - Select “NIN Retrieval”
- Your 11-digit NIN will be displayed (₦20 charge may apply)
Option 2: Use NIMC Mobile App
- Download the MWS: NIMC Mobile ID app
- Log in with your security PIN
- View your NIN and virtual slip on the dashboard
Option 3: Visit a NIMC Center
- Present your ID card and details
- They can help retrieve or confirm your NIN
Common Mistakes When Checking NIN Digits
- Entering 10 or 12 digits: Your NIN must be exactly 11 digits
- Confusing NIN with tracking ID on enrollment forms
- Using old slips: Always confirm with *346# if unsure
- Mistaking virtual NIN (vNIN) for the real one — vNIN changes with each generation, but your NIN remains the same
FAQs About NIN Digits
Can I have more than one NIN?
No. NIMC allows only one unique NIN per person for life. If you mistakenly enroll twice, the system may detect duplication and suspend both NINs.
Is the NIN same as BVN?
No. Your NIN is different from your Bank Verification Number (BVN). The BVN has 11 digits too, but is managed by banks and not linked to NIMC records unless you authorize it.
What if my NIN has less or more than 11 digits?
It's likely incorrect. Only a proper 11-digit number from NIMC or *346# is valid.
Your NIN is exactly 11 digits. Memorize it, keep it safe, and use only trusted platforms (like the *346# code or NIMC app) to verify or retrieve it.
The NIN is now required for everything — from opening bank accounts to writing exams and using mobile phones. Make sure your 11-digit number is correctly linked and saved.
