Hi k t. You can definitely port your landline number to NumberBarn! Porting is what we do. However, you won't be able to port from NumberBarn directly to Google Voice. NumberBarn's numbers are classified as "wireline" and Google Voice will only accept wireless numbers. You can port your number to a cheap wireless service first and then on to Google Voice. We offer some help in our Help Center on this if you are interested: https://help.numberbarn.com/knowledge_base/topics/will-my-new-carrier-accept-a-numberbarn-number If you have any other questions about porting, feel free to reach out to us via email to support@numberbarn.com
