my stupid boyfriend?

My boyfriend stoled my cell phone because i have two and he got jelouse. He says he doesnt have it i know he took it he has done it before. I think he might have sold it because i called my number and it says my call canot be completed as dialed please check the number and dial again. What number do i call to report it stolen? I think who ever has it changed my number. Its a verizon prepay. I have pics and stuff on it.
