Yes, you can port your Google Voice number. However, once you do port the number you will no longer be able to use it at anything else other than 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 first unlock it. There is a fee that comes with unlocking your number.
To unlock your number:
- Go to www.google.com/voice/unlock and sign into your Google Voice account.
- If you only have one Google Voice number click Unlock my number underneath your Google Voice number. If you have more than one number, select the number you wish to port away from the drop down menu and then click Unlock my number.
- Click Continue to confirm that you wish to unlock your number.
- Sign into Google Wallet to complete your port out process.
Once you're done your Google Voice number is ready to be ported out.
