Overview

Transferring your Google Voice number to OpenPhone requires unlocking the number first through Google’s portal, then completing the standard porting process. The entire process typically takes 1-2 weeks.

Before you begin

Requirements

  • Active Google Voice account with the number you want to port

What to know

  • Your old Google Voice messages remain in your Google account after porting
