I have a text conversation that I don't know who the number is and have never sent a text to. Is it possible for someone to hack your number and have a text conversation with someone without you knowing?
We're concerned to learn you have a text conversation that you did not create, Lmathias. Let's take a closer look into what's going on. What is the make and model of your phone? What message app is in use? What is the date of the message thread? Is it possible this is an old contact that was deleted?

It's an iPhone 7 plus and I am using the apple message app with multiple dates from the thread. Again I don't know the number and never had a text conversation with it.
Should I do a factory reset or wouldn't that take care of the problem? Can someone hack my phone buy just knowing the number?
A factory data reset can certainly do the trick. Please make sure you content is save before making such move. Getting hacked is always a risk in this day an age, however, it is extremely rare and hard to happen by just knowing the number.
