Let’s start with the honest truth, not sugarcoated:
You cannot fully change the phone number linked to your NIN 100% online in Nigeria (as of 2026).
And yes, that’s frustrating. In a world where you can open a bank account from your sofa, NIN still insists on seeing your face and fingerprints. But there’s a good reason for that, and this guide will explain everything clearly.
This article answers:
- Whether you can change your NIN phone number online
- What methods actually work
- Why physical verification is still required
- The safest way to update your NIN in 2026
No fake hacks. No rumours. Just the real process approved by Nigerian authorities.
What Is the “Phone Number Linked to NIN”?
The phone number linked to your NIN is your primary contact number stored in the National Identity Database.
It is used for:
- OTP verification
- SIM-NIN linking
- Government services
- Bank identity checks
- NIMC notifications
In simple terms, it’s your digital recovery key.
If you lose that number, everything becomes harder.
Why People Want to Change Their NIN Phone Number
Most people try to update their NIN number because:
- They lost the old SIM
- The number was blocked
- The phone was stolen
- They no longer use the line
- They registered with an agent’s number
- The SIM expired
Very common. Very normal.
Short Answer: Can You Change NIN Phone Number Online?
Fully online? No.
Partially online? Yes.
You can start the process online, but final approval requires physical biometric verification at a NIMC office.
This is not a bug. It’s a security feature.
Why NIMC Does Not Allow Full Online Change
Let’s use logic.
Your NIN controls:
- All your SIM cards
- Your bank identity
- Your BVN
- Government records
If anyone could change your NIN number online, fraud would explode overnight.
So NIMC requires:
- Fingerprint verification
- Facial match
- Physical presence
Because identity should not be editable like a Facebook profile.
Official Ways to Change Phone Number Linked to NIN (2026)
There is only one real method.
Everything else is fake or incomplete.
Method 1: Visit a NIMC Office (Only Guaranteed Method)
This is the only official and permanent solution.
What You Need:
- Your NIN slip or NIN number
- A valid ID (if available)
- Your new phone number
- Your fingerprint and face
Steps:
- Visit any NIMC enrollment center
- Request NIN data modification
- Ask to change phone number
- Provide new number
- Verify biometrics
- Pay official modification fee (if required)
Your new number gets linked within 24–72 hours.
This method:
- Updates the central database
- Reflects across all banks and networks
- Works nationwide
No shortcuts beat this.
Can You Start the Process Online?
Yes, but it won’t finish online.
You can:
- Book NIMC appointment
- Fill modification form
- Pre-enter new details
But you must still:
- Show up physically
- Scan fingerprints
- Confirm identity
So think of online steps as pre-registration, not completion.
Can I Change My NIN Number via USSD?
No.
USSD codes like:
*346#
allow you to:
- Check NIN
- Check linked numbers
But they cannot modify NIN data.
USSD is for viewing, not editing.
Can I Change It Through My Bank?
Some banks help you:
- Retrieve NIN
- Update BVN-NIN linkage
But no Nigerian bank can change your NIN phone number.
They don’t control NIMC database.
Can I Change It at MTN, Airtel, Glo?
No.
Networks can:
- Link SIM to NIN
- Unlink SIMs
- Verify identity
But they cannot edit your NIN profile.
Only NIMC can.
Why Online “NIN Change Services” Are Dangerous
If a website or agent says:
“Change NIN number online – no office visit”
That is a scam.
They may:
- Steal your NIN
- Clone your identity
- Register SIMs under your name
- Use your data for fraud
There is no legal API for public NIN modification.
What Happens If You Don’t Update Your NIN Phone Number?
If your old number is gone, you may face:
- No OTP access
- SIM linking failures
- Bank verification issues
- Delays in government services
- Trouble recovering identity
Your NIN becomes like a locked account without the password.
Special Case: Lost NIN Phone Number
This is very common.
If you lost your NIN SIM:
You must:
- Visit NIMC
- Request phone number change
- Verify biometrics
- Register new number
There is no online recovery for this.
Even NIMC cannot bypass biometrics.
How Long Does It Take to Change NIN Number?
| Method | Time |
|---|---|
| NIMC office | 1–3 days |
| Busy locations | Up to 7 days |
| System delays | Rare but possible |
Once updated, the new number becomes your official contact across Nigeria.
Does It Cost Money?
Officially:
- NIMC may charge a small modification fee
- The amount depends on location
It is not expensive, and you should never pay agents.
If someone asks for large fees, walk away.
How to Check Your Current NIN Phone Number
You can confirm linked numbers by dialing:
*346#
Then:
- Select NIN services
- Choose “Check linked numbers”
You’ll see all numbers attached to your NIN.
This helps you verify if:
- Old number still exists
- Wrong number was used
- Multiple lines are present
