Why is My NIN Invalid? What to Do

Let us treat this issue because if your NIN is Invalid, you need help with the guides below, so let's find out why your NIN is Invalid and what you can do to fix the situation.

Despite the struggle and all the time wasted during NIN registration, many still have issues with invalid NIN after registering and receiving their NIN. Usually, it occurs when you try to link your NIN to your phone number. When attempting to link your NIN to your SIM, there are three main reasons you may get an invalid NIN error.

• BVN generated NIN
• NIN registered a long time ago
• Newly registered NIN
• Problem from NIMC

BVN generated NIN

Suppose you're opening your first bank account without a NIN. After generating your Bank Verification Number (BVN), you'll receive a National Identification Number (NIN).

Isn't that great? It has saved you the hassle of visiting a NIMC enrolling centre for NIN registration. You're mistaken. The error is because NIMC has cautioned Nigerians only to use the NIN obtained from their BVN if it has been updated at an authorised NIMC registration centre.

Should I? Carry your BVN-generated NIN to the nearest NIMC Enrolment centre and inform the agent or official that you want to validate it? Validation removes the error.

NIN registered a long time ago

The second cause for the incorrect NIN issue is that your NIN was obtained long ago. Your NIN may not have been authenticated by the NIN site, not because you registered it long ago. Don't worry. Instead, verify the NIN at a nearby NIMC enrolling centre.

Newly registered NIN

After enrolling for NIN at an authorised NIMC enrolment location, you'll be handed a slip with your tracking ID and requested to return it on a specified date (typically 1-5 working days) to get your NIN.

You'll receive your NIN slip when you return on the specified date. Newly registered NINs are generally inactive the day you receive the Slip, so you can't use them for a while. How come? The NIMC needs time to verify registration details. Validating your information eliminates the invalid problem.

How can I proceed? Ask the NIMC representative at the enrolling centre where you registered how long it would take to use your NIN fully. After a short period (typically two weeks), you can use your NIN without problems.

Problem from NIMC

Your name, BVN, and other attributes will be requested during NIN enrollment or registration. If NIMC detects incorrect data, your NIN won't be activated, resulting in an invalid error message.

In this situation, take your NIN slip to the nearest NIMC Enrolment Centre and notify the NIMC officer that you want to change the details. Your NIN will be validated and active when you complete the following steps.
