Is their a way to check who is prank calling me?

Question

Well in the middle of the night i get prank called all the time and i heard their is a way to check the phone # even if they do private call(witch can u tell me what it is? the numbers) like *67 or somthing

but i also heard u can press like *49 or somthing and it tells u teh number that just called you

Answer 1

*69 will call the number back - probably won't work if they used *67.

*67 will block your number when you call someone.

I haven't heard of *49 before.
