To update the phone number on your NIN, use the official NIMC Self-Service Modifications portal at selfservicemodification.nimc.gov.ng. You need a police report that shows the new number in the format NIMC requires.
NIMC lists Phone Number as one of the details you can change through that portal — alongside name, date of birth and address. Use only nimc.gov.ng domains.
Quick answer
Get a police report for the phone number change. Write the number without a leading 0 after the +234 country code (example style from NIMC: +234 812345…).
Open https://selfservicemodification.nimc.gov.ng/, verify your NIN, and register or log in.
On your dashboard, choose the phone number modification option.
Pay the official fee shown in the portal. NIMC’s fees page lists N2,000 per updatable field for adult modifications (Date of Birth is a separate, higher fee). Confirm the amount on screen before you pay.
Upload your police report, enter the new phone number carefully, preview the change, tick the attestation box, and submit.
Keep your modification transaction slip. After approval, follow the portal instructions to get your updated NIN slip by email or print from your dashboard.

A police report for the phone number modification
The new phone number written the way NIMC asks: without 0 after +234 (for example +234 812345…)
A way to pay the official modification fee inside the portal
NIMC’s self-service page lists the police report as the required document for Phone Number Modification. Make sure the number on the report matches what you will enter on the portal.
Current fees
On nimc.gov.ng/fees, NIMC lists Modifications (Adults) as N2,000 per updatable field. Date of Birth is not in that group and has its own fee.

Phone number is treated as an updatable field on the self-service portal. Always confirm the exact amount shown in the portal checkout before you pay — fees can be updated on the official site.
Step-by-step: update your NIN phone number
1. Get a police report with the correct number format
NIMC requires a police report for phone number modification. On the report and in the portal, provide your phone number without 0 after the +234 country code — NIMC’s example is +234 812345…
2. Open only the official portal
Go to https://selfservicemodification.nimc.gov.ng/. Ignore WhatsApp agents, lookalike domains, and apps that ask for OTP outside NIMC.
3. Verify your NIN and log in
Begin by verifying your NIN and logging in, as described on NIMC’s self-service modifications page. Register first if you do not yet have a portal account.
4. Choose phone number modification
On your dashboard, select the phone number modification option — not name, address or date of birth. Each change type has its own documents and fee rules.

5. Pay the official fee
Complete payment securely inside the portal. Follow the payment options shown for your phone-number request. Confirm N2,000 (or whatever amount appears) before you finish.
6. Upload documents and submit
Upload a clear copy of your police report. Enter the new phone number exactly as on the report. Preview the change, tick the attestation box, and submit. Save the modification transaction slip from your modification table.
7. After approval
When NIMC approves the request, you should get a notification. NIMC’s self-service guide says your NIN slip can be sent to your email, and you can also print from your dashboard.
If you need the slip later, see our guide: How to Download and Print Your NIN Slip.

Common problems
Wrong number format — NIMC wants +234 without a leading 0 after the country code. Fix the police report and portal entry if they do not match.
Blurry or incomplete police report — re-upload a clear scan that shows the new number.
Paying on a fake site — if the URL is not selfservicemodification.nimc.gov.ng, stop and start again on the official portal.
Selecting the wrong modification type — phone, name, address and DOB are separate options with different documents.
Scam warnings
NIMC directs self-service changes to selfservicemodification.nimc.gov.ng only.
Do not send your NIN, OTP or card details to WhatsApp agents or social media helpers.
Do not pay Remita or card fees on random sites that copy NIMC’s look.
If someone asks you to share your portal password, it is a scam.
