Have you forgotten your MTN phone number and need a quick way to retrieve it? Whether you have just purchased a new SIM card or need to confirm your existing number, you can check your MTN number using a simple USSD code.

The easiest method we recommend is dialling *663#. It displays your MTN number in a pop-up message and also sends an SMS containing the number to your SIM.

In this guide, you will learn how to check your MTN number, why another commonly recommended code may fail, and how to use the myMTN NG app as an alternative.
