eFax is an Internet fax service of j2 Global that enables sending and receiving of fax documents in digital format rather than a traditional paper fax machine.

eFax's services have been integrated into some HP printer models[1] and offered as an app for Microsoft Office 2013.[2] Subscribers may obtain features such as digital signatures, mobile applications, and large file sharing with a paid subscription.[3]


The first service branded as eFax was created by British-born entrepreneur Mark Oglesby in early 1997, providing a service to integrate email with existing fax technology. Separately, eFax (trading under the domain name efax.com) began as a service of JetFax, Inc., which in the 1980s and 1990s manufactured and sold JetFax fax machines.[4] JetFax was founded by Lon Radin and Rudy Prince in 1988 and was recognized by some as the first company to develop the laser fax machine, replacing the heat-treated fax machines prominent in the 1980s.[citation needed]

On February 8, 1999, JetFax changed its name to eFax.com, Inc. and began to offer the eFax online fax service.[5] During the dot-com bubble, the company's stock shot up, but fell during the bust and it ran out of funds. In late 2000, eFax.com was acquired by rival JFAX, which had offered a similar electronic fax service. Upon the purchase, the company changed its name to j2 Global Communications, Inc.[6] and then in 2011 to j2 Global, Inc.[7]

In August 2010, Hewlett-Packard introduced a new line of printers incorporating the eFax service.[1][8]

On March 15, 2011, j2 Global, Inc. obtained a US trademark granting the company exclusive rights for use of the term "eFax" in connection with Internet faxing services.[citation needed]

In August 2012, Microsoft introduced the eFax app for Microsoft Word 2013.[2]

As of 2014, eFax is increasingly being used by organizations such as colleges (over 1,000 schools) for its electronic signing/fax features.[9]


In addition to basic online fax functionality, eFax allows for integration with email, phone, and cloud storage. Further features include keyword search, use of digital signatures, and encrypted fax.[10]

eFax has also developed smartphone apps for iPhone and Android which allow for direct faxing of photos and scans taken from the mobile device.[10] Other app features include digital signature using fingerprint or picture, text editing, cover sheets, and PDF support.[11] The applications are free to download, but the free version is limited and has a trial period.[12]


eFax offers multiple pricing models (eFax Plus and eFax Pro) for its online fax services, for individuals and businesses of different sizes and needs. It also offers multiple enterprise-level plans branded as "eFax Corporate."[13]



eFax has received multiple Editors Choice awards from PC Magazine for its services and smartphone apps.[14][15] In September 2012, j2 Global appeared on the InformationWeek 500 list of technology companies.[16]

In 2013, j2 Global's creative team also won two bronze statuettes at the 33rd Annual Telly Awards in the public relations and computers/information technology categories, for their work in promoting j2 Global's cloud services and the eVoice virtual phone service.[17]


Some eFax users have reported that they were billed even after they cancelled their accounts and that they were not issued a refund.[18] Another complaint is that eFax does not allow porting out of assigned numbers.[19] Other companies acquired by j2 Global (such as Onebox) have been the target of similar complaints, ranging from toll-free number portability issues to high cancellation fees.[citation needed]
