How to Correct NIN Details Online: Name, Date of Birth and Fees (2026)

A small error on your National Identification Number (NIN) record can cause big problems. It can block a bank account update, delay a passport, stop JAMB or NYSC from validating your records, or make SIM linking fail. The good news is that you can correct NIN details online without queuing at an enrolment centre. This guide shows you how to correct NIN details through the NIMC self-service modification portal, which documents you need, what each change costs and how to avoid the most common mistakes.

Why you may need to correct NIN details

Your NIN record is now used almost everywhere in Nigeria. Banks, telecom companies, JAMB, WAEC, NYSC, the Immigration Service and many employers check it. If your NIN shows a different name or date of birth from your other documents, verification fails.

The most common reasons people need to correct NIN details are:

• A spelling error in the surname, first name or middle name
• First and middle names in the wrong order
• A change of surname after marriage or divorce
• A wrong date of birth typed during enrolment
• An old address or phone number
• A missing middle name that appears on your certificates

Whatever the cause, the fix starts with NIMC. Other agencies, including JAMB, copy your details from the NIMC database. If you need to match your JAMB record, read our guide to the JAMB NIN alignment service after you finish here.

First, check your current NIN details

Before you change anything, confirm exactly what NIMC holds. You can do this in a few ways:

• Dial *346# from the phone number linked to your NIN and follow the menu to retrieve your NIN.
• Use the official NIMC mobile app to view your digital NIN slip.
• Check your printed NIN slip or improved NIN slip.

Our step-by-step guide on how to check your NIN number covers each option. Write down every field exactly as it appears, including spaces and hyphens. Then compare it with your birth certificate, school certificates and bank records.

Where to correct NIN details: the NIMC self-service portal

NIMC moved NIN modification online, and enrolment centres stopped handling most modification requests in 2024. Today, the main route to correct NIN details is the NIMC self-service modification portal at selfservicemodification.nimc.gov.ng.

You can also find official information on the NIMC website. Always type the address yourself or follow links from NIMC’s verified pages. Fake “NIN correction” websites are common, and they collect money and personal data.

What you can change through NIN modification

The self-service portal handles the main types of NIN modification:

• Change of name: correcting spelling, adding a missing name or changing a surname after marriage
• Change of date of birth: correcting a wrong day, month or year
• Change of address: updating where you live
• Change of phone number: updating the number linked to your record

Each change type has its own fee and its own supporting documents. Some changes, especially date of birth, come with strict limits, so read the rules carefully before you submit.

How much does NIN modification cost?

Fees widely reported from NIMC’s portal are:

• Change of name: ₦1,522.50
• Change of address: ₦1,522.50
• Change of phone number: ₦1,522.50
• Change of date of birth: ₦16,340

These figures come from 2024 and 2025 reports, and fees can change. The portal shows the current fee before payment, so confirm it on screen before you pay. Payments are processed online through Paystack. Never pay a “NIMC agent” into a personal account.

Documents you need to correct NIN details

The right documents make approval much more likely. Prepare clear scans or photos before you start:

For a change of name

• A sworn affidavit stating your old name and new name
• A newspaper publication of the change of name, where required
• Marriage certificate, if the change is due to marriage
• Supporting records showing the correct name, such as a birth certificate or school certificate

For a change of date of birth

• Your National Population Commission (NPC) birth certificate or attestation
• The NPC certificate number, which the portal checks

For a change of address or phone number

• A recent utility bill or other proof of address, if asked
• Access to the new phone number for OTP verification

Make sure every scan is sharp, well lit and readable. Blurry uploads are a common reason for rejection.

How to correct NIN details online: step by step

Here is the typical process on the NIMC self-service modification portal. Screens may change after updates, so follow what you see.

1. Open the portal. Go to selfservicemodification.nimc.gov.ng on a phone or computer.
2. Verify your NIN. Enter your NIN and complete the verification. An OTP is usually sent to the phone number or email linked to your record.
3. Log in to your dashboard. Create or confirm your login details.
4. Choose “NIN Modification”. Select the type of change you want: name, date of birth, address or phone number.
5. Enter the correct details. Type them exactly as they appear on your supporting documents.
6. Pay the fee. Pay through the Paystack checkout shown on the portal.
7. Upload documents. Attach your affidavit, certificate or NPC attestation.
8. Tick the attestation box. Confirm that the information is true.
9. Submit and save your slip. The portal generates a modification transaction slip. Save it as a PDF and take a screenshot.

After submission, NIMC reviews your request. Check your dashboard and your email for updates.

Changing your date of birth: special rules

A date of birth change is the most sensitive type of NIN modification, so NIMC treats it carefully. Keep these rules in mind:

• Get NPC attestation first. You must register or attest the correct date with the National Population Commission before you apply.
• The NPC number is checked. During the process, you enter your NPC certificate number. The portal validates it, and the date field may fill in automatically and become locked.
• It can usually be done only once. Reports on the portal’s rules say you can correct your date of birth through self-service only once. Later attempts may not be processed or refunded.

Because of these limits, double-check the correct date with your parents and your oldest records before you start. Do not guess.

Name correction or change of name: which one do you need?

Many people mix these up, but the difference affects the documents you upload. A name correction fixes a mistake. Your real name never changed, but someone typed it wrongly, for example “Ifeoma” saved as “Ifeomah”. A change of name means your legal name actually changed, for example after marriage, divorce or a formal decision to adopt a new name.

For a simple correction, your strongest proof is an older official document that shows the right spelling, such as a birth certificate or WAEC certificate, along with an affidavit. For a true change of name, NIMC usually expects the legal paper trail: an affidavit, a newspaper publication and, where relevant, a marriage certificate or court document.

Choosing the right path matters. If you upload marriage documents for what is really a spelling error, or only an affidavit for a full surname change, your NIN modification request may be delayed or rejected.

Final checklist before you click submit

Run through this short checklist every time you correct NIN details. It takes two minutes and prevents most rejections:

1. The new details match your supporting documents exactly, letter for letter.
2. You selected the correct modification type on the portal.
3. Every uploaded document is clear, complete and in the format the portal accepts.
4. The fee shown on screen matches what you expected, and you are paying through the portal’s own checkout.
5. Your phone is charged and your network is stable, so the OTP and payment do not fail midway.
6. You know where you will save the transaction slip once it appears.

If any item is not ready, stop and fix it first. A rushed submission costs more time than a short pause.

How long does it take to correct NIN details?

NIMC does not publish one fixed timeline for every request. Simple changes, such as a phone number update, may be processed faster than a name or date of birth change, which need document checks. Keep your transaction slip and check your dashboard regularly.

If your NIN modification is urgent, for example because of a JAMB deadline, start as early as possible. Do not wait until the last week.

Common problems and how to fix them

Users have reported a few recurring issues with the self-service portal. Here is how to handle them:

OTP not arriving

Make sure the phone number linked to your NIN is active and has network coverage. Wait a few minutes before requesting a new code. If your old number no longer works, you may need to update the phone number first.

Payment made but request rejected

Read the rejection reason carefully. Usually, a document was unclear or did not support the change. Keep your payment receipt and contact NIMC support with your transaction slip.

Portal not loading

Try a different browser, clear your cache or use a computer instead of a phone. Busy periods can slow the site, so try early in the morning.

Details still wrong after approval

Check again after a few days, because updates can take time to reflect across systems. If the problem remains, contact NIMC with your slip.

After you correct NIN details: update everywhere else

Once NIMC approves your NIN modification, other records still need to match. Work through this list:

• Banks: update your BVN details at your bank so your name and date of birth match. Our guide on how to check your BVN helps you confirm what your bank holds.
• SIM cards: confirm that your lines are linked to the updated NIN. See how to link your NIN to your SIM.
• JAMB and school: use the JAMB alignment window if your JAMB biodata now differs from your corrected NIN.
• Passport and driver’s licence: update these when you next renew, and carry your new NIN slip.
• Employer and pension: inform your HR department and your pension fund administrator.

Matching records across agencies saves you from repeated verification failures later.

Avoid NIMC scams and fake agents

Because many people struggle with the portal, fake agents offer to “do it fast” for a fee. Protect yourself:

• Use only the official NIMC self-service portal and verified NIMC pages.
• Pay only through the portal’s checkout, never into a personal account.
• Never share your OTP with anyone, including people who claim to work for NIMC.
• Keep copies of every receipt, slip and message.
• If someone already has your details, monitor your SIMs and bank accounts closely.

If you are helping a family member, sit with them and let them enter their own OTP. If you notice a payment you did not make or a request you did not submit, report it to NIMC and your bank the same day.

A worked example

Tunde’s NIN shows “Babatunde Adewale Ojo”, but his certificates say “Babatunde Adewale Ojo-Ade”. His bank account update keeps failing. To correct NIN details, he swears an affidavit, publishes the change of name in a newspaper and scans both documents. He logs in to the NIMC self-service modification portal, selects change of name, enters “Ojo-Ade” exactly as it appears on his certificates, pays the fee shown and uploads his documents. He saves the transaction slip and checks his dashboard every few days.

After approval, he updates his BVN at his bank, confirms his SIM links and keeps a printed copy of the new NIN slip. One clean process now fixes problems in several places.

Tips for a smooth NIN modification

• Start with the oldest, most official document you have, such as your birth certificate.
• Use the same spelling everywhere: certificates, bank, school and NIN.
• Use a stable internet connection to avoid failed payments. Our guide on how to save data on Android helps if you are on a small bundle.
• Do one change at a time, unless the portal clearly allows combined changes.
• Save every slip and receipt in one folder on your phone and in your email.

Correcting NIN details for children and elderly relatives

Many families need to correct NIN details for children or older relatives who cannot use the portal alone. You can help, but the record still belongs to them. Use their own phone number and email where possible, and let them confirm every detail before you submit.

For a child, the birth certificate from the National Population Commission is usually the most important document. Make sure the name order on the birth certificate matches what the school uses. If the child will write common entrance, WAEC or UTME soon, fix the record early so that exam bodies receive the right details.

For elderly relatives, finding an accurate date of birth can be harder, because older records may be missing. Gather what you can, such as baptism records, old school documents or an age declaration, and ask NIMC or the NPC which documents they accept before you pay for a date of birth change.

Quick checklist before you start

Before you open the portal to correct NIN details, confirm that you have everything in one place:

• Your 11-digit NIN and access to the phone number or email linked to it.
• Clear scans of every supporting document, saved in a format the portal accepts.
• A working debit card or payment method for the fee shown on the portal.
• The exact spelling of your names and your correct date of birth, copied from your oldest official record.
• A stable internet connection and a charged phone or laptop.

With this checklist done, the NIN modification process usually goes much more smoothly, and you are less likely to need a second attempt.

Frequently asked questions

How much does it cost to change my date of birth on NIN?

Reported fees are ₦16,340 for a date of birth change, but confirm the current amount on the portal before paying.

How many times can I change my date of birth?

Will correcting my NIN affect my bank account?

Your account stays open, but your bank may ask you to update your BVN details so they match your corrected NIN. Do this soon to avoid failed verifications.

What if my phone number linked to NIN is lost?

You may need to retrieve your SIM from your network first, or update the phone number on your record so you can receive OTPs.
