How to Correct NIN Date of Birth, Name & Phone Number on NIMC Portal Online
Updating your National Identification Number (NIN) details — such as your date of birth, name, or phone number — is now more streamlined thanks to the NIMC Self-Service Modification Portal. This official platform allows Nigerians and legal residents to make necessary corrections to their NIN records without visiting a physical NIMC office.
Making sure your NIN information accurately reflects your current personal details is essential because the NIN is widely used for identity verification across government services, banking, education, telecommunications, and digital verification systems.
What Details You Can Correct Online
Through the NIMC self-service portal, you can update several key pieces of your NIN data, including:
Name (first, middle, or last)
Date of Birth (DOB)
Phone number
Address
Email address
Other personal information as allowed by NIMC policies
These modifications can be done securely online without a physical visit to a NIMC enrolment centre.
Before You Start: Requirements
Before you attempt any corrections, you should have:
Your 11-digit NIN and means to verify it
A valid phone number or email linked to your NIN
Supporting documents required for each type of modification
For DOB corrections, a birth certificate or NPC attestation (National Population Commission) is typically required
For name corrections due to marriage or legal changes, an affidavit, marriage certificate, or official change document may be needed
For phone changes, a valid proof of phone ownership and sometimes a police report (depending on portal rules) may be required
A debit/ATM card to pay modification processing fees online
Supporting documentation requirements must be uploaded as part of your application.
Step-by-Step: How to Correct Your NIN Details Online
Step 1: Visit the NIMC Self-Service Portal
🔗 Open your web browser and go to the official NIMC self-service modification portal:
https://selfservicemodification.nimc.gov.ng/
This is the official portal where NIN modifications are processed online.
Step 2: Log In with Your NIN
Enter your 11-digit NIN
Complete any required verification, such as biometric confirmation or face match if prompted
Follow on-screen instructions to access your dashboard
Once logged in, you’ll see a list of available modification options.
Step 3: Choose the Detail to Correct
From your dashboard, select the field you want to update:
✔ Name
✔ Date of Birth
✔ Phone number
✔ Address
✔ Email address
Each category will open a separate form or section for that particular correction type.
Step 4: Upload Supporting Documents
For each correction type, you will be prompted to upload relevant documents. Some common document guidelines include:
Date of Birth: Birth certificate or NPC attestation
Name: Court affidavit, marriage certificate, or official change document
Phone Number: Proof of current phone number

Make sure all documents are clear and legible before uploading.
Step 5: Make Online Payment
Once your files are uploaded and verified on the portal:
Proceed to payment using the integrated payment gateway
Use your ATM/debit card (Visa, MasterCard, etc.)
Pay the required service fee (this may vary per correction type)
Note: Date of birth modifications typically attract a higher processing fee than other changes.
Step 6: Submit and Track Your Request
After payment, submit your request and note the confirmation details.
You will receive a transaction slip or reference number
Keep this for tracking and future reference
The portal may notify you by email or SMS once your correction has been approved and effected
Turnaround times can vary — most users see corrections reflected in a few days after approval.
Common Issues and Support Tips
If your birth certificate is not recognised, you may need to complete a birth attestation with NPC before updating DOB on NIMC.
Some users report occasional portal validation errors — contacting NIMC support or retrying later can help.
After correction, ensure all linked services (banks, SIM registration, BVN, etc.) reflect the updated NIN information.
Why Keeping Your NIN Details Accurate Matters

By using the self-service portal, you can ensure:
Your identity records match your official documents
Verification systems provide accurate authentication
Services that depend on NIN data process smoothly
Accurate NIN data directly supports identity integrity in digital and offline systems.
