- SIM Registration Nigeria
- GLO USSD Code
If you’re a GLO subscriber in Nigeria, linking your National Identification Number (NIN) to your SIM is mandatory by law. Failure to do so may lead to disconnection or restrictions on your line — including inability to make calls or access mobile data.
In this 2024 guide, we’ll walk you through all the available ways to link your NIN to your GLO SIM, how to confirm if your linking was successful, and what to do if you’re facing errors during the process.
Let’s get into it.
Why You Must Link Your NIN to Your GLO Line
The Nigerian Communications Commission (NCC) mandated all telecom operators — including GLO — to ensure that subscribers link their NIN to their phone numbers. This is to:
- Enhance national security
- Prevent SIM-related fraud
- Create a unified national database
Failure to link your NIN can result in:
- Blocked outgoing calls
- No access to mobile data or services
- Possible line suspension
Option 1: Link NIN to GLO via USSD Code
This is the easiest and fastest way to link your NIN.
Steps:
- Dial *996# on your GLO line
- Select the option to link your NIN
- Enter your 11-digit NIN
- Submit and wait for confirmation
You should receive a message confirming successful submission. It may take up to 48 hours for the link to reflect in the system.
Option 2: Link Your NIN to GLO Using SMS
If the USSD method doesn’t work for you, use this SMS method:
Steps:
- Type a message in this format:
UPDATENIN NIN FirstName LastName
(Example: UPDATENIN 12345678901 John Musa) - Send to 109
You should receive a confirmation message from GLO shortly afterward.
Option 3: Link NIN Through the GLO NIN Portal
GLO has a dedicated web page for NIN linking.
Steps:
- Visit https://www.gloworld.com/ng/nin/
- Enter your GLO phone number
- Type in your 11-digit NIN
- Fill in your full name
- Submit the form
You’ll get a confirmation message once your submission is received.
Option 4: Visit a GLO Customer Service Center
If you’re getting errors with the online or SMS method, or if your NIN is not validating, visit any nearby GLO office with:
- A valid National ID slip/card
- Your mobile phone and SIM card
They’ll assist you in linking your NIN manually and can troubleshoot any issues instantly.
How to Confirm If Your GLO Line Is Linked to Your NIN
There are two easy ways to check your linking status:
- Dial *996# and select “NIN Status.”
- Or: Use the NIMC NIN Verification Portal
If the line isn’t linked, the system will prompt you to repeat the linking process.
Common Problems & Fixes
| Problem | Possible Fix |
|---|---|
| Error submitting via USSD | Retry after a few minutes, or switch to SMS method |
| NIN not valid | Confirm your NIN via *346# or check NIMC status |
| Still blocked after linking | Wait 48–72 hours or contact GLO customer care |
| NIN mismatch | Ensure the name on your NIN matches the name registered with your GLO line |
Tips for Successful NIN Linking on GLO
- Always double-check your NIN digits before submission.
- Avoid submitting the same NIN multiple times — it may cause delays.
- Keep the confirmation message as a backup in case of future issues.
- If your SIM was not originally registered in your name, you’ll need to do a SIM update or re-registration at a GLO office.
Final Thoughts
Don’t wait until your GLO line gets restricted or blocked before taking action. Linking your NIN is not just a legal requirement; it also protects your mobile identity.
