You can port your Google Voice number to Dropbox Fax. However, after you port the number, you'll only be able to use it as an inbound fax number.
Your Google Voice number is automatically locked to prevent it from being ported out without your consent. Before you can port your Google Voice number to another service provider, you must unlock it. There's a fee to unlock your number.
To unlock your number:
- Go to Google Voice.
- If you’re not already signed in to your Google account, click Sign in.
- Click 🗀 (settings).
- Go to the Account section.
- Click Unlock under the number you want to unlock.
- Complete the payment with your Google Account.
Your Google Voice number is ready to be ported out.
