Most people, because of the numerous amount of information they keep in their head, most times find it difficult to keep their personal phone numbers in their heads.
If you can somehow save it on your phone or write it down in your dairy or somewhere else for easy reference fine but if you cannot do that then the best way to check your phone number on the MTN network anytime you would like to use it is by keeping the short code for checking in your head.
The short code is *156#.
Now here is how you check for your MTN number:
1. Dial the short code (which is *156#).
There will be a pop-up menu.
2. On the pop-up window, select number 1. (Check My Number)
Your number will be displayed.
