How to Get a Google Fax Number (2024 Guide)

Author: Richard Haase  Updated April 1, 2024

A Google fax number is a name given to an online fax number that is linked to your Gmail address, and lets you send and receive faxes through it.

Google doesn't provide fax numbers or services,  but we can get one through third party online fax services. These are companies that basically let you fax over Internet using your email, without having to buy additional equipment.  They use a technology known as FOIP, which lets convert incoming analog faxes into digital files and vice versa.

Online fax services have been around for quite some time now. These are services that charge you an affordable fee to be able to send and receive a certain amount of pages per month. For this, they provide you a virtual fax number in charge of redirecting incoming faxes to your Gmail account.

Most of these services let you create a free account. What’s great about this is that these accounts come with all the set of features included with the service. You basically get a basic plan for a full month, and among these features is the availability of a free fax number to receive fax.

At the moment of signing up you’ll be asked to enter the email address you want to use for receiving faxes, and then you’ll need to pick the number associated with the account. There are two options: a local or a toll-free number.

At the moment of creating your account, you'll need to enter your credit card information. But you don’t need to worry this works the same as any free trial, they won’t charge you any fee to your credit card unless you keep using your account after the month has passed. Just make sure you cancel it before the trial period and you won’t have any problems. Also, it is a good idea to stick with reputable online fax vendors such as eFax or Ringcentral Fax among others.

How Virtual Fax Numbers Work

For the user, an online fax number will automatically receive faxes on a Google Mail account, so they can be read electronically. But what happens in the background before that?

When someone sends you a fax, she/he will have to dial your virtual fax number. There will be no difference the person sending you the fax, but this fax number sends the transmission through a digital line to powerful fax servers. It's on these servers that the fax documents will be converted to a digital file, more specifically a PDF which can be opened on any computer or mobile device.

Once the document is converted, it is included as an attachment in an email and then sent to your Gmail account. From there you can download, read or print it as you like. This process takes only a few seconds to complete, and is 100% secure (even more than traditional faxing!).

How to Use Your Google Voice Number to Fax

Changing your fax number and updating your contacts can be a real pain in the you-know-where, especially when you have had a fax number for years. In these cases we recommend you move your current number to a digital platform.

If you wish to fax with your Google Voice number, this is way to do it.

The number porting is done through online fax services, taking advantage that they have already relationships with phone companies across the United States in some countries around the World.

To start you need to request the porting process to your current fax service. You may be asked to pay an additional fee to complete the process.

By porting a number you are moving it from a landline to a virtual line. This means your number will now work over an Internet connection, using what is called Fax Over Internet Protocol, or FoIP.

Now, because this number works over the Internet, it’s not just a matter of quickly changing the company handling the number. The process may take a few days to complete, until the information has been propagated across the Web.

Services know this may cause interruptions and problems when trying to reach your line, that’s why they give you a temporary fax number. This number will forward incoming faxes to a Gmail account while the propagation is completed. Once the process is finished you'll be able to fax online.

Is This Way of Faxing Secure?

Security to send and receive faxes is extremely important, especially if you work in fields like law, healthcare and finance, where there are strict regulations governing the sharing and faxing of sensitive information.

Organizations of all kinds still choose fax as the preferred method to share documents, even when sharing a file these days is as easy as using an instant messaging app. That’s because they value security above else. Despite all the conveniences of instant messaging, we have been proven time and time again that mass-oriented online messaging technologies are not as safe as we would want to.

When you send faxes with a machine things are relatively secure. The document travels directly to its recipient using an analog phone line service, and there is no chance that this information gets intercepted. On top of that, you get a confirmation when your fax is fully printed on the other end, unlike modern apps that have the option of hiding this information.

But what happens in the case of online faxing? If we are using the email channel, does this means that our documents are vulnerable? In this article we will take a look at these questions. You’ll learn that email faxing is actually more secure than using a fax machine.

This is what happens when you send faxes:

  1. You compose an email message with an attachment
  2. The email goes your online fax service’s fax servers, where the attachment is converted into a fax file.
  3. The service encrypts this information and sends it to the receiver’s fax machine.

As you can see, you are not sending the fax to another email. You send it for conversion on the service’s fax servers which act as a protective “wall” against interceptions. The document goes then through additional security measures before reaching the fax machine.

The only way other people can read a fax you send is if your email information is compromised. That’s why it is recommended you use a dedicated email for online faxing strong password and change it at least every month. Gmail lets you know at the moment of creating your account if your password meets the strength criteria.

On the other hand the online fax service gives you maximum security. With additional options designed to ensure your documents arrive safely and privately.

Security Features of Online Fax Services

Password protection. On your service’s settings area, you can add password protection for faxes arriving to your email. enter and confirm your password, and next time a fax arrives your email, it will contain PDF protection, meaning only you can read its contents. The password can be changed or turned off at any time without accessing Gmail.

Encryption. Before your fax travels from the fax servers to the receiver, they will be protected with point-to-point encryption. This type of encryption adds a cover to your data, effectively hiding it.

Automatic fax removal. You can set your faxes to be deleted from your account after they have been opened. This option can remain active for scheduled amount of time.

Unique file types. There are some fax services that have developed their own apps to send and receive faxes with encryption. They basically deliver your fax in a unique file format, that you won’t be able to read unless you use the app or program. It’s a very ingenious way of handling additional fax security, although it depends on the operating system you are using.

Access Control. Corporate online fax services let you access all your faxes from a virtual drive. This cloud storage is protected using 256-bit AES encryption.
