Safety While Texting

[AC Question]

I have a Samsung Galaxy Grand Prime. Whenever I'm texting someone, their phone number is shown below their name. And I was wondering if there was a way to change that (for safety reasons)? Any total stranger can simply read the name and phone number and track them down

Yes anyone could read this, but they would need to be holding your phone and have a decent memory to remember an 11 digit (or more) phone number.
