The National Identification Number (NIN) is a key ID issued by the National Identity Management Commission (NIMC). It is required for activities like opening a bank account, applying for passports, accessing public services, and carrying out other official tasks.
Sometimes, people notice mistakes in their NIN details—such as incorrect names or wrong dates of birth. These errors can lead to issues when using government or financial services.
If you find any mistakes in your NIN, it is important to correct them quickly. This guide shows you the steps to fix those errors safely and easily
Why You May Need to Correct Your NIN Details
Your NIN is used for various government and official purposes like banking, employment checks, and voter registration. If your information is wrong, it may affect services linked to your identity.
Errors in names, birth dates, or other personal information can cause mismatched records. This might delay important processes or cause rejections. Fixing these issues early will help you avoid future stress.
Making corrections on time helps you use your NIN for official matters without problems. It also ensures that your government records are accurate and up to date.
What NIN Details Can Be Corrected?
You can apply for corrections in the following areas:

Name
- What can be corrected? This covers situations like typos (e.g., “Jonh” instead of “John”), missing middle names, or a complete mismatch with your legal name (e.g., your birth certificate says “Amina Bello,” but your NIN lists “Amina Yusuf”).
- Why it matters: Your name is a key identifier. Errors can cause issues with bank accounts, travel documents, or government services.
- Example: If you registered with a nickname but now need your full legal name, you can request this change.
Date of Birth
- What can be corrected? If the day, month, or year was entered incorrectly during your NIN registration (e.g., “12th May 1990” instead of “12th May 1980”).
- Why it matters: An incorrect date of birth can affect age-related services like pensions, voting eligibility, or even job applications.
- Example: If you accidentally selected the wrong year on a dropdown menu during registration, you can fix it to match your official documents like a birth certificate.
Phone Number
- What can be corrected? You can update this if the number you originally registered is no longer active, lost, or if you simply switched to a new one.
- Why it matters: Your phone number is often linked to NIN-related notifications, SIM card registration, or banking alerts. An outdated number could lock you out of these services.
- Example: If you registered with “234-803-1234 5678” but now use “234-806-1234 5678,” you can update it to stay connected.
Gender
- What can be corrected? If the gender recorded (e.g., “Male” instead of “Female”) doesn’t match your identity or official documents.
- Why it matters: Gender errors can create confusion in systems like healthcare, insurance, or legal documentation where this detail is relevant.
- Example: If a data entry mistake marked you as “Male” when you’re “Female,” you can have it corrected.
Address
- What can be corrected? You can update your address if you’ve moved to a new house, city, or even state since your initial registration.
- Why it matters: An accurate address ensures you receive official correspondence or services tied to your location, like tax documents or voter registration.
- Example: If you registered with an address in Lagos but now live in Abuja, you can update it to reflect your current residence.
Marital Status
- What can be corrected? This applies if your marital status has changed (e.g., you got married or divorced) and you need to update your surname or status.
- Why it matters: This keeps your records consistent, especially if you’ve legally changed your name after marriage or need to revert to a maiden name post-divorce.
- Example: If you registered as “Fatima Ali” (single) but got married and now use “Fatima Ibrahim,” you can update your NIN to reflect this.
Steps to Correct Your NIN Details (Offline Method)

To make any corrections, follow these steps:
1. Visit an NIMC Enrollment Center
You must go to an official NIMC office or an approved registration center. Find the nearest one through the NIMC website or visit a designated government office.
2. Fill Out the Data Correction Form

5. Biometric Verification
Once your payment is confirmed, NIMC staff will take your biometric details again to update your records. This ensures your identity is correctly stored in the system.
