Below are the most efficient ways to check your number and manage other MTN account details.

USSD Codes – Fast and Reliable Options

For many MTN users, the quickest way to find their number is by using a USSD code. Whether you’re on a smartphone or a basic phone, these methods work seamlessly.

Dial *123#

This is one of the most frequently used methods.

  • Dial *123#.
  • Select Option 1 for ‘My Tools’.
  • Choose Option 1 again for ‘My Number’.

Your MTN number will pop up immediately.

Dial 1231*1#

Another shortcut that works just as effectively is dialling 1231*1#.
Your number appears instantly, saving you time.

Dial *663#

This option also works quickly.
Just enter *663# and wait a few seconds for your number to appear on your screen.

Whether you use *123#, 663#, or 12311#, each one is a working code to check MTN number in Nigeria.

Use the MyMTN App for More Account Details

Prefer something visual and more detailed? The MyMTN app helps you do more than just check your number.

  • Send ‘Care’ via SMS to 5018.
  • You’ll receive a link to download the app.
  • Once installed, sign in using your MTN line.

Your phone number, airtime balance, and data usage details will all be visible from your dashboard.

The app is perfect for tracking subscriptions and making quick top-ups. You can even cancel unwanted MTN subscriptions directly from the app or using the linked code.

Try the “Call Me Back” Option

When you’re out of airtime, this method comes in handy.

  • Dial *133#.
  • Enter the phone number of someone you trust.

They’ll receive a “Please Call Me” message with your MTN number attached.

Reach MTN Customer Service

Still unsure about your number?

  • Dial 180 on your MTN line.
  • Speak with a customer care agent.

They can help retrieve your number and assist with any account-related queries.

Use the SIM Pack

If you’ve kept the original SIM card pack, your MTN number might be printed on it, along with your SIM serial number (ICCID).

Support staff can use this ICCID to recover your number if needed.

Make a Call or Send a Message

This remains one of the simplest methods.

Just call or text someone you know. Ask them to tell you the number that shows up on their phone.

It’s fast, direct, and doesn’t require any code.

Check Airtime and Data Balances

Managing your MTN account goes beyond checking your number. You’ll also want to keep tabs on your airtime and data usage.

Check Your Airtime

  • Dial *556# to see your current balance.

Check Your Data

  • Dial *131*4# to view your active data bundle and balance.

Knowing how to check these regularly helps you avoid sudden disconnections or low-balance issues.

Check Your MTN Number Online

You can also check your number through web-based options:

  • Download the MyMTN app, or
  • Visit the MTN Nigeria website to sign in.

Your dashboard will show your MTN number, airtime, data plans, and more.

Additionally, these platforms make it easy to link your NIN to MTN, which is mandatory for keeping your line active.

Other Handy Codes and Info

Verify NIN Linking

Dial *785# to confirm your NIN is properly linked to your MTN line.

Find Your SIM Serial Number

Look at the SIM card or the original packaging. This number, known as the ICCID, is useful if your SIM has issues.

  • Dial one of the code use to check MTN number to see if it’s still working.
  • Visit the nearest MTN centre for SIM diagnostics or reactivation.
  • You can also call 180 for additional help.

With all these methods available, you’ll never be stuck wondering what your MTN number is. From using a quick code to check my MTN number to accessing full account details via the app or online platform, there’s always an option that works fast and reliably.
