What Are the Differences Between eFax and RingCentral?


Both eFax and Ringcentral promise to help their customers eliminate the need for fax lines, fax machines, and tons of paper. Yet, they have significant differences that can help you make an informed decision as a potential customer.

Dedicated focus: 

eFax focuses on online faxing, so it remains on the leading edge of faxing technology rather than RingCentral. 

On the other hand, RingCentral offers several communication products to its clients. Its faxing services may be purchased as part of its available packages or alone. But because it has a broad focus doesn’t mean it provides less robust faxing capabilities.

RingCentral users can even send a fax directly from their email. They simply have to add a fax cover sheet, attach files, and they’re good to go.


eFax online fax service allows users to keep faxes in encrypted file types and has limitless fax storage, so long as the account is active.

RingCentral offers 5GB storage for free and unlimited storage for its Ultimate plan.

Electronic signing and management:

RingCentral Fax users can edit, sign, and send faxes electronically. eFax users are given access to a digital signature tech. This feature allows them to comment and sign on faxes.

With eFax, you can hand-write your signature on paper, scan a picture with your phone’s camera, and save the file to eFax. You can then use that electronic signature anytime you need to sign or send an online fax.

This electronic signing capability eliminates the long process of printing, signing, scanning, and storing physical paper.

Customer support:

All eFax users have access to the same level of technical assistance. At the same time, RingCentral’s support depends on the package available to the customers. Those who pay more get superior-tech assistance.


Both services have different features to ensure the security of users' data. For instance, eFax hosts encrypted inbound fax for download. Even its online storage is accessible and secure anywhere. Files that contain sensitive information remain confidential.

RingCentral, meanwhile, stops unwanted faxes from coming through with its user-level blocking capabilities. When users transmit faxes, it’ll be over an encrypted connection. 

RingCentral allows users to preview, annotate, and print faxes right from their computer to ensure maximum security and control. Meanwhile, all incoming faxes are stored securely in the user’s account and can be sent later as email attachments.

Now, let’s highlight their similarities.

What Are the Similarities of eFax and RingCentral?

Neither provides payment for activation or installation. Additionally, the two tools provide VoIP PBX solutions. VoIP PBX, also called IP PBX, is a business telephone system that place and receives phone calls over the internet. It also allows businesses to set up virtual call management systems in their office.

eFax offers a 30-day trial period, wherein users may use all electronic faxing capabilities that are usually available for paying clients. Similarly, RingCentral provides a free trial of 30 faxes or seven days, whichever occurs first.

How To Choose an Online Fax Service: A Buyer’s Guide


1. Evaluate your needs

The key to finding the right service provider is considering the volume of faxes you realistically send and receive. Some online faxing plans may be inexpensive but have a lower monthly fax limit.

2. Speak with several vendors

Contact various vendors to evaluate both their products and their customer service. How do their customer service representatives discuss company offerings?

3. Know the fee structures

Unexpected costs and hidden fees make budgeting difficult. Although most online fax service providers list their pricing on their websites, it may take additional research to know about their extra charges – long-distance fees, set-up fees, and overage costs.

The right online fax tool can save you money and time while providing secure transmissions. 

eFax is the definition of focus and simplicity. If you need online faxing features alone, eFax may be your best choice. It’s a trusted service and has a large storage capacity. 

On the other hand, RingCentral is ideal if you prefer a multi-platform besides online faxing. RingCentral has integration options for cloud storage, has a wide range of acceptable file formats, and makes advanced faxing simple.
