I have a cell phone with Verizon and I want to change my phone number?

I have a cell phone with Verizon and I want to change the phone number. Does anyone know if you get the first time number change for free? Or if not...how much will it cost?I have a cell phone with Verizon and I want to change my phone number?
It just depends on what sales rep you get. Some do it for free. If not its $15 for a telephone number change. I know theyre suppose to waive it if u move out of zip code or ure recieving unwanted phonecalls.
