Staying safe with reverse cell look up

Everyone has cell phones these days, even my teenagers.  They mostly use their phones to communicate with my husband and I, to let us know where they are going and what time they’ll be coming home.  My teenage daughter uses her cell phone a lot to chat with her friends and texting is popular with both of my kids.  As a parent, I never imagined I would have to monitor their phone usage until my daughter started getting calls from unknown numbers from far-off area codes.  I don’t know who could have gotten her phone number but wanted to make sure it wasn’t some kind of creep and was a little bit scared for her.  When looking those numbers up using reverse cell look up, I found out who the caller was and it was actually one of her friend’s parent’s cell phones.  Everything turned out ok but I sure was relieved that I was able to know who was on the other end of those calls!
