I will also answer some frequently asked questions about managing MTN phone numbers to help you maintain updated details in their system. Whether you need to provide your number to someone else or confirm your identity, the following methods will ensure you have instant access to your MTN mobile number information.

How to Check MTN Number Using USSD Code

MTN makes checking your phone number remarkably straightforward using Unstructured Supplementary Service Data (USSD) codes.

USSD codes require dialing a short string of numbers directly from your phone dial pad to trigger a function. Every major network in Nigeria, including MTN, uses USSD codes for customers to quickly check balances, purchase data, and more.

Here is a step-by-step walkthrough to check MTN number using *131# code:

What You Need

  • Working MTN SIM card inserted into phone
  • Active MTN mobile plan with minutes to make a call
  • Access to phone dial pad

Step 1: Dial 1311# Code

To initiate the number check process, simply open your phone’s dial pad and enter the following USSD code:


Once dialed, hit the phone icon on your mobile screen to call the number.

Step 2: Wait for Response Message

After calling, you will typically see “please wait” or “processing” message flash on your screen. Within 10-15 seconds, MTN will automatically send a text response containing details.

Step 3: Note Down Number Shown

Carefully look at the message sent back to your device. It will display important information including:

  • Main account number referenced by MTN
  • Associated cell phone number registered to SIM card
  • Available airtime balance

Be sure to note down or save your returned 10-digit MTN mobile number for future reference.

Step 4: End Session

The confirmation text from the USSD session will ask if you wish to check another part of your account. Simply exit or hit end on your smartphone to complete the process.

And that’s it! Using the 1311# MTN number check code requires less than 30 seconds to accurately retrieve your registered phone number details from their databases.

Locating Your MTN Number on SIM Packaging

If you still have the original SIM card holder and paperwork that came with your MTN SIM purchase, you likely have your 10-digit cell number printed directly on the items.

Here is a quick guide to finding and identifying your MTN phone number using just the SIM packaging:

What You Need

  • MTN SIM card holder
  • SIM purchase receipt or paperwork

Step 1: Locate SIM Packaging

If you still have the plastic SIM card sleeve or holder intact, this will be printed with a special serial number. While not the same as your final working mobile number, MTN references this SIM serial during activation.

Step 2: Find Number on Receipt

Any official paperwork, whether the activation instructions or payment receipt from an authorized MTN dealer, will contain your new MTN cell phone number. This paperwork prints automatically upon registration of a new prepaid or contract account creation.

Step 3: Match Number to SIM Packaging

Once you locate the printed number on either your SIM packaging or other documents, you can cross-reference it to your registered account. This official paperwork from MTN should accurately display the mobile number paired to that SIM.

While not as instantly accessible as the USSD method, keeping your SIM holder and receipts lets you independently double check your number if ever uncertain.

Using MyMTN Mobile App Number Check

Beyond using USSD codes and physical SIM packaging, MTN subscribers can also confirm their mobile numbers directly in MyMTN app.

Frequently Asked Questions

Why does my MTN number show differently across my devices?

In rare cases, an issue during activation or phone number porting can create a discrepancy in how your MTN number displays in services like WhatsApp or on call screens. Always cross-reference using the official channels above.

Can I check if an MTN number is currently active?

Unfortunately individual subscribers cannot independently verify if another MTN number is currently active. You would need to call the assigned number to confirm if currently working. However, contacting MTN directly provides the most reliable method to check another MTN number’s status.

Does MTN send the updated number details via SMS or Email?

Whenever you successfully change or update your official registered phone number with MTN, they will notify your old and new number via SMS. This ensures you have a record of the change on your end for documentation.

Is there a code to check MTN data bundle balance?

Yes, you can quickly check available MBs in your data bundle by dialing 1314# to view data balance and bonuses. Other USSD codes help check airtime, borrowing limits and more.

What happens if I lose my SIM card?

If your physical MTN SIM card is damaged, lost or stolen, you must contact MTN customer service immediately to suspend service temporarily until a new SIM is activated on your number. Failing to report missing SIM cards leaves you vulnerable to illegal use of your number.
