Code to check my MTN Phone number in Nigeria? *663# Guide for 2026
Dial *663# on your MTN line and press call. Your number appears on the screen and arrives by SMS a moment later.
4 Ways to Check Your MTN Number
| *663# | Dial and read the pop-up |
| *123*1*1# | Backup code, same result |
| Phone settings | Often blank on many SIMs |
| Call a friend | Your number shows on their screen |
Step by Step With *663#
- Put the MTN SIM in your phone
- Open the dialler and type *663#
- Press call
- Read the number, then check your SMS for a saved copy
USSD runs on the network’s signalling channel, so *663# works even on a SIM with no airtime and on basic phones with no internet. The SMS copy means you can find the number again later in your messages.
Phone Settings Method
On Android, open Settings, About phone, then SIM status. On iPhone, open Settings, Phone, then My Number. A blank field means the number was never written to the SIM, so use *663# instead.
If Nothing Shows
- Confirm the SIM is an MTN line
- Restart the phone and redial
- Try again outside peak hours
- Dial *123*1*1# instead
- Link your NIN if the SIM is barred, then wait a few hours
Still stuck? Contact MTN customer care or visit an MTN service centre with your ID, and they can confirm the number tied to your SIM.
Save It for Next Time
Store the number in your contacts, send it to your email and write it somewhere safe. Never share your number with strangers who claim to be MTN staff, and never give out your PIN or OTP.
