Question regarding bill

Apr 30, 2018
Someone who is a Verizon subscriber used to show up on my invoice. That day I looked at my bill as it was coming out and it was one of the days I was contacted by the person. The number was on the bill. By the end of the day the number no longer showed up. Can verizon customers request having their numbers withheld from being displayed on other customers bills. If so is this a law all cell phone companies have to offer?
