Google Voice has no built-in fax feature. Use Fax.Plus separately to keep calls and texts, or port an eligible number to Fax.Plus for faxing only, without calls or SMS.

Choose based on whether you need to keep using your number for calls and texts. Sending a fax does not require moving your Google Voice number.
Before unlocking your number, ask Fax.Plus to check whether it is portable. Porting is available on Premium, Business and Enterprise plans. Wait for confirmation of eligibility and the required documents before proceeding.
For a personal Google Voice account, unlock the number before requesting a transfer. If your number belongs to Google Workspace, contact your administrator for the organization's transfer process. Do not apply the personal-account instructions to a managed Workspace number.
