How To Check My MTN Number in Nigeria

If you want to check your MTN number in Nigeria, the fastest method is to dial *663# on your MTN line. Your phone number should appear on the screen almost immediately.

You can also try *123*1*1# on some lines. And if you cannot use USSD for any reason, there are still other easy ways to see your MTN number without guessing.

That is the short answer.

Now let me show you the full picture, because this is one of those topics where old articles often mix working methods with outdated ones.

How to check my MTN number

If you just want the fastest code, use this first:

• Dial *663#

If that does not work on your line, try:

• Dial *123*1*1#

Other ways to check your MTN number include:

• opening the myMTN app
• checking the SIM pack
• calling or flashing another number
• contacting MTN customer care

For most people, *663# is the easiest option.

What is the code to check my MTN number?

The main MTN number-check code in Nigeria is:

• *663#

Once you dial it, MTN should display your phone number on the screen.

There is also another code many MTN users still use:

• *123*1*1#

I always suggest trying *663# first because it is the simpler option.

How to check my MTN number using USSD

This is the method most people want because it is fast and works on both smartphones and small button phones.

Method 1: Dial *663#

Follow these steps:

1. Open your phone dialer
2. Insert your MTN SIM if it is not already inside the phone
3. Dial *663#
4. Press the call button
5. Wait for the result to appear on the screen

If the code goes through successfully, your MTN number will show on the display.

That is usually all you need.

Method 2: Dial 1231*1#

If the first code does not work, try this alternative:

1. Open your dialer
2. Dial *123*1*1#
3. Send it
4. Wait for the pop-up or on-screen response

On some lines, MTN may display your number through that self-service menu path.

Which MTN code should you try first?

If you are in a hurry, use this order:

1. *663#
2. *123*1*1#
3. myMTN app
4. call or flash another number
5. contact MTN support

That is the cleanest order because it saves time.

How to check my number on MTN if the USSD code is not working

Sometimes the code fails because of network issues, a temporary USSD problem, or a SIM-related issue.

That does not mean you are stuck.

Here are other ways to find your MTN number.

Check your MTN number with the myMTN app

If you already use the myMTN app, this is one of the easiest methods.

Steps to check your MTN number on the myMTN app

1. Open the myMTN app
2. Log in with your MTN line
3. Check the account dashboard or profile area
4. Your MTN phone number should appear on the main screen or account section

This method is useful if:

• your USSD code is failing
• you manage more than one MTN line
• you want to confirm the number tied to your app account

One thing to note though.

If you have never logged into the app before, you may need access to the SIM to receive an OTP first.

Check your MTN number by calling or flashing another line

This is the old method, but it still works.

If you have airtime or you are close to someone with another phone, do this:

1. Insert the MTN SIM in your phone
2. Call a friend or family member
3. Ask them to read out the number showing on their screen

If you do not have airtime, you can try a flash / call-me-back style approach if your line supports it, or simply place a missed call and end it quickly.

This method is still helpful when:

• USSD is not responding
• your phone has network signal but menu codes are failing
• you want to confirm the number exactly as it appears to others

Check the MTN number from the SIM pack

If the SIM is still new or you kept the original pack, look at it.

In many cases, your MTN number is printed on the SIM pack or starter pack material that came with the line.

This is one of the most overlooked methods.

I have seen people stress over USSD codes when the number was already sitting on the SIM jacket in their drawer.

Check your MTN number from phone settings or contacts backup

This one does not always work, but it is worth checking.

Some phones save the SIM number under:

• Settings
• About phone
• SIM status
• My phone number

On Android, the path may look something like this:

• Settings
• About phone
• Status
• SIM status

On some phones, the number field may be blank. On others, it may show correctly.

You can also check if the number was previously saved inside:

• WhatsApp account info
• Telegram account details
• Truecaller profile
• your own saved contact card
• banking or fintech apps already linked to the line

This is not the official MTN method, but it can still help.

How to check my MTN number if I lost the SIM pack

If you no longer have the SIM pack, do this in order:

Option 1: Dial *663#

This should still be your first move.

Option 2: Use *123*1*1#

If the first code does not work, try the second one.

Option 3: Open the myMTN app

If the line is already linked there, your number may show instantly.

Option 4: Call someone

A simple call can reveal the number quickly.

Option 5: Contact MTN customer care

If nothing else works, ask MTN directly.

How to contact MTN customer care to know your number

If you cannot check your MTN number through USSD or the app, MTN support can help.

You can contact MTN through these channels:

• 300 from an MTN line
• myMTN app
• MTN support channels on the MTN Nigeria website
• MTN social support pages
• WhatsApp support where available

If you contact customer care, be ready to confirm that the SIM belongs to you. They may ask for details linked to the line before disclosing account information.

Can I check my MTN number without airtime?

Yes. In most cases, you do not need airtime to check your MTN number with *663# or *123*1*1#.

That is one reason USSD is the best option.

You also do not need airtime if:

• you are using the myMTN app over available internet access
• you still have the SIM pack
• the number is already saved somewhere in your phone records

The only method that may require airtime is when you decide to place a normal call to another line.

Can I check my MTN number on a new SIM?

Yes.

If the SIM has been activated and is already connecting to the MTN network, you should be able to check the number using:

• *663#
• *123*1*1#

If the SIM is brand new and you are having trouble, try this first:

• reinsert the SIM
• wait for network signal
• restart the phone
• try the code again

If the line still refuses to show the number, use the SIM pack or contact MTN support.

How to check my MTN number on a button phone

This works almost the same way.

On a small Nokia-style phone or any basic phone:

1. Open the dial screen
2. Dial *663#
3. Press send
4. Wait for the result

That is one reason USSD remains useful. It does not depend on smartphone apps or internet access.

What to do if *663# is not working on your MTN line

If *663# fails, do not panic. Try these quick fixes.

1. Confirm that the SIM is MTN

It sounds obvious, but it matters.

Many people carry multiple SIMs and dial the right code on the wrong network.

2. Retry after a few minutes

USSD sessions fail sometimes because of network congestion or a temporary service issue.

3. Try the alternative code

Dial:

• *123*1*1#

4. Restart your phone

A simple restart can fix temporary SIM or network registration issues.

5. Move to an area with stronger signal

Weak signal can interrupt USSD responses.

6. Use the myMTN app or call another line

Do not stay stuck on one method.

7. Contact MTN if the SIM seems faulty

If the line is not responding to multiple MTN codes, the issue may be bigger than just the number-check code.

Is *663# still the MTN number check code in Nigeria?

As of the current guidance used by many MTN Nigeria users, *663# remains one of the main codes used to check an MTN number. *123*1*1# is also still commonly referenced as an alternative self-service route.

The reason I mention both is simple.

MTN changes menu structures from time to time. Some lines respond better to one code than the other. So instead of forcing one answer only, it is safer to give readers the working options in the right order.

Difference between checking your MTN number and checking your tariff plan

These are not the same thing.

A lot of readers accidentally search one when they mean the other.

To check your MTN number

Use:

• *663#
• or *123*1*1#

To check your MTN tariff plan

MTN may use a different self-service path for tariff information, often through the *123# menu or other dedicated tariff codes.

So if your real question is not “what is my number?” but “what MTN plan am I on?”, that is a different article entirely.

Best method if you use multiple MTN SIMs

If you use more than one MTN line, I recommend doing this:

• save each number in your contacts immediately after activation
• label them clearly, for example:
  • MTN personal
  • MTN bank alerts
  • MTN business line
  • MTN data SIM
• link the important ones to the myMTN app
• keep the SIM packs for new lines

This saves you from repeating the same problem every few months.

Quick comparison of ways to check your MTN number

Method	What to do	Needs airtime?	Best for
USSD main code	Dial *663#	No	Fastest option
Alternative USSD	Dial *123*1*1#	No	Backup method
myMTN app	Open app and view account	Usually no, if already logged in	Smartphone users
Call another line	Call or flash someone	Sometimes	When USSD fails
SIM pack	Check the starter pack	No	New or stored SIMs
Customer care	Contact MTN support	Not always	Last resort

The best way to avoid forgetting your MTN number again

Once you recover the number, do these small things immediately:

Save it in your contacts

Create a contact like:

• My MTN Number
• MTN Main SIM
• MTN Bank Line

Send it to yourself on WhatsApp or Telegram

This makes it easy to find later.

Write it inside your notes app

Especially if the SIM is for banking, business, or data use.

Keep the SIM pack

At least until you are sure you have memorized the number.

Link it to your email or password manager notes if it is a critical line

That matters if the number is tied to OTPs, banking apps, NIN linkage, or work contacts.
