Can I switch the phone I'm using through my account with no charge?

I'm buying a used iPhone that is compatible with Verizon (I already checked through my online account). I have a Galaxy 7 now. I'm wondering if I can switch my number from the Galaxy to the iPhone. Would I be able to do that, from my home, with no charge?

Added (1). It's too late to call Verizon right now so I was hoping for some experiences from others.
