How to Fax With Google Voice

Can you ​fax using Google Voice numbers?​ Yes. Back when Google Voice was first introduced, it was a brilliant way for users to send and receive calls, voice messages, and text messages from anywhere, anytime.

Now, you can ​unlock and transfer your current number in Google Voice ​and use it to send and receive faxes over a virtual fax line. Fortunately, you can effortlessly sync your GV number with an online fax service like CocoFax. In this article, you’ll learn how to do it!

In fact, most online fax services assign you a random fax number that can only send faxes but not receive faxes at all. However, with CocoFax, you can choose your own free fax number once you sign up, and use it to send and receive faxes.
