Method 1: Check MTN Number via ussd Code
This is the method I used to retrieve my MTN number when I couldn’t remember it. I consider it one of the easiest and most straightforward ways for anyone to get their number from the MTN network. It’s free, with no service charges attached, and doesn’t require technical knowledge. It doesn’t matter, whether you have a basic phone or an Android device, this method works on any type of phone.
Here’s how I was able to get my number using the USSD code:
- Pick up your phone.
- Go to your mobile dialer.
- Dial *123# and press send.
- Wait for the prompt.
- Select 1 (ACCOUNT INFO).
- Under MY TOOLS, select 1 (My Number).
Your number will be displayed on your screen, and you will also receive a message from MTN containing your number.
Alternatively, you can retrieve your number by sending a text message to 123:
- Open your messaging app.
- Type “NUMBER.”
- Send it to 123.
Shortly, MTN will send you a message containing your number.
While the USSD code gives you two ways to get your number – dialing *123# or sending a message with “NUMBER” to 123. My preferred method is dialing *123#.
Method 2: Use The MyMTN app To Check Number on mtn
The MTN app method not only allows you to check your number but also helps you manage other account services, such as checking airtime or data balance. To get your SIM number via the app, follow these time-saving steps:
- If you are using Android, download and install the MTN app from the Google Play Store. iPhone users can visit the Apple Store.
- Open the app.
- Allow the login interface to open.
- Enter your login details (if it’s your first time, you need to sign up to get your login details).
- Once inside the app, go to the account section.
- Click on “My Number,” and your number will be revealed.
This method is convenient, as you can also check other account information. However, note that only those with some ICT knowledge may find this method easy to understand.
Method 3: Calling a Family Member or Friend
If you have airtime on the SIM, you can call a family member or friend to share your number with you. Even if the number isn’t saved in their contacts, when you call, your number will display on their device, and they can send it to you via call, text message, or WhatsApp.
Method 4: Call Your Other Line
If you have more than one phone and SIM, you can get your number in less than 60 seconds. Follow these easy steps:
- Phone A: Insert the MTN SIM card for which you want to know the number.
- Phone B: Insert the other SIM (it can be from any network) into the second phone. (Note: you must know this number to enable you to call and retrieve your other line number. For example, call 08037688540.)
- Call 08037688540 from Phone A, and your MTN number will display on Phone B. Copy and save the number.
Method 5: Call MTN Customer Care
The last method is to call MTN customer care for assistance in retrieving your number. Here are the steps to follow:
- Dial 180 from the MTN SIM card you want to retrieve the number for.
