Following the Nigerian government’s directive on NIN-SIM integration, linking your NIN to your GLO line is now mandatory. This directive applies to new and existing Glo users, as well as users of other network providers like MTN, Airtel, and 9mobile.

How to Link NIN to a Glo Number in 2025

Start by checking your NIN status to confirm that it has not been previously linked. 

To check your Glo NIN status, dial *996#, select option 1, and the status of your NIN will be sent via SMS. Then, go ahead to link your NIN if you need to. But if you don’t know your NIN, dial *346# on your phone to retrieve your NIN. Alternatively, you can visit any NIMC office close to you.

That said, these are the different ways to go about linking your NIN to your Glo line.

Using the NIMC App to Link NIN to a Glo Line

You can use the National Identity Management Commission (NIMC) mobile app to link NIN to a Glo line. This app allows you to link up to seven numbers to a single NIN.

To link your NIN to your Glo number using the NIMC app in 2025, follow these steps:

1. Download the NIMC app from your device’s app store.
2. Open the app and enter your NIN, or scan the QR code on your NIN slip.
3. Create a 6-digit PIN to secure the app when prompted.
4. Go to the app dashboard, select “My Devices” and then choose “Add Mobile Number“.
5. Enter your Glo phone number and proceed to submit. Glo will send an OTP to your line for verification.
6. Input the OTP and confirm. 

Congratulations! You’ve successfully linked your NIN to your Glo line.

Text “UPDATENIN NIN FirstName and LastName” to 109 using your Glo line. For example, you text “UPDATENIN 12345678910 Solo Solomon”
