Ever been stuck at a recharge counter, fumbling for your MTN number?
Or maybe you’ve got multiple SIMs and can’t keep track?
Forgetting your phone number isn’t a crime—it’s human.
In Nigeria, where MTN powers millions of lives, knowing your number fast is a game-changer.
This guide cuts through the noise.
No fluff, just the exact steps to check your MTN number in 2025.
Why You Need to Know Your MTN Number
Picture this: You’re trying to share your number with a new client.
Your brain freezes.
You’ve got three SIMs, and the MTN one’s digits are a blur.
Or worse, you’re filling out a form, and your number’s nowhere in your head.
Sound familiar?
Here’s why nailing this matters:
- Stay Connected: Your number’s your lifeline for calls, texts, and data.
- Save Time: No more digging through old messages or SIM packs.
- Avoid Embarrassment: Never stutter when someone asks for your digits.
- Account Management: You need your number for airtime top-ups, data plans, or NIN linking.
MTN’s got over 70 million users in Nigeria.
With that many people, forgetting a number is as common as Lagos traffic.
Let’s fix it.
Method 1: Check Your MTN Number with USSD Codes
USSD codes are your fastest bet.
No internet, no app, no airtime needed.
Just your phone and a few taps.
Think of it as a cheat code for your MTN number.
Here’s how to nail it:
Using *663#
- Dial ** *663# ** from your MTN line.
- Boom—your number pops up on the screen.
- Save it or jot it down.
Using *123#
- Dial *123# .
- Pick Option 1 (Account Info).
- Select Option 1 again (My Number).
- Your MTN number flashes up, plus you’ll get an SMS with it.
Pro Tip: If *663# doesn’t work, try *123*1*1#.
It’s the same deal, just a shortcut.
I once forgot my number at a bank.
Dialed *663#, and in 10 seconds, I was sorted.
No stress, no sweat.

Method 2: Use the MyMTN App to Find Your Number
Got a smartphone?
The MyMTN app is your digital wingman.
It’s not just for checking your number—it’s a hub for data, airtime, and more.
Here’s the play-by-play:
- Download the App: Grab it from Google Play Store or Apple App Store.
- Log In: Use your MTN number (if you know it) or sign in with Google/Apple.
- Check Profile: Open the app, head to “Account” or “Profile.”
- Find Your Number: It’s right there, staring at you.
Why It’s Great:
- No memorizing codes.
- You can manage data and airtime in one go.
- Perfect if you’re always online.
Heads-Up: You’ll need internet to use the app.
No data? Stick to USSD.
My cousin swore by this app after losing his SIM pack.
He checked his number and bought data in under a minute
Method 3: Call or Text a Friend to Reveal Your MTN Number
Low-tech, high-reward.
If you’ve got airtime, this is stupidly simple.
Here’s how it works:
- Call a Friend: Dial someone close who’s got your number saved.
- Ask for Your Number: Have them read the caller ID.
- No Answer? Try SMS: Send a text or a “Call Me Back” message with *133#.
- Your number shows up as the sender.
When to Use This:
- You’re out of data and USSD isn’t working.
- You’ve got at least ₦1 airtime for a quick call.
I used this trick at a party.
Called my buddy, he shouted my number across the room.
Problem solved, vibes intact.
Method 4: Contact MTN Customer Care for Your Number
When all else fails, MTN’s got your back.
Their customer care is 24/7, ready to save the day.
Here’s the drill:
- Dial 180: Call from your MTN line.
- Follow Prompts: Pick your language, then ask to speak to a rep.
- Request Your Number: Explain you need your MTN number.
- Alternative: Dial 08031000180 from another network.
Why It Works:
- It’s free from an MTN line.
- Reps are trained to handle this fast.
Downside: You might wait a few minutes for a rep.
Last year, my sister’s USSD code kept failing.
She called 180, and a rep gave her number in two minutes flat.
Method 5: Check Your Phone Settings (Dual-SIM Users)
If you’re rocking a dual-SIM phone, your MTN number might be hiding in plain sight. Here’s how to dig it out:
- Go to Settings: Open your phone’s settings.
- Find SIM Management: Look for “SIM Cards” or “Mobile Network.”
- Check SIM Info: Your MTN number should be listed under the SIM slot.
When This Shines:
- No airtime or data needed.
- Perfect for tech-savvy folks with multiple SIMs.
Catch: Some older phones don’t display numbers in settings.
My colleague found his number this way after juggling two MTN SIMs. Took him 30 seconds.
Bonus Tips to Never Forget Your MTN Number Again
You’ve got your number now. Let’s make sure it sticks. Here’s how to lock it in:
- Save It: Store your number in your contacts as “My MTN Number.”
- Memorize It: Practice saying it out loud a few times.
- SIM Pack Trick: Keep your MTN SIM pack safe—it’s got your number printed on it.
- Link Your NIN: Dial *996# to check if your number’s tied to your National Identification Number.
Keeps things official and secure.
I started saving my numbers as contacts after forgetting one mid-call. Haven’t had a brain freeze since.
