Is eFax legit?

Legit

You can count on eFax being genuine, a long-running online fax service that gives you a fax number to use by email or app, though leaving it is where things snag. Plans renew by themselves and are paid in advance, so a cancellation not completed before renewal can cost another full period.

What we checked

  • Owned by Consensus Cloud Solutions
  • Parent listed on Nasdaq
  • Head office in Los Angeles
  • Ratings on other review websites: 4.5/5

Watch out for

  • An email saying you have a new fax that asks you to log in or open an attachment.
  • A CCSI EFAX line on your card statement, or J2 EFAX SERVICES on an older one.
  • A bill above the plan price because pages beyond the plan's allowance are charged as extra usage.

eFax plan renewed after you asked to cancel?

We help you write it, it gets its own public page, and you can have it sent to eFax as a formal letter.

Common customer service questions about eFax

How do I file a complaint about eFax?

Do you have a dispute or a bad customer experience with eFax? Report it through our website to maximize the chance of getting it resolved.

We help you write an effective complaint in minutes. Our AI models are trained on thousands of effective complaint letters. Then we push it through emails, social media, paper complaint letters and other tools at our disposal. And you are not alone: our helpful community is there for advice.

How do I contact eFax customer service?

Call eFax customer service on 1 (800) 878-7151 or email help@mail.efax.com. The eFax support page, linked in the contact details above, also has the help centre and a separate route for eFax Corporate accounts. Have your eFax fax number, the email address on the account and the date of any charge in question ready.

Renewal or page charge to dispute? Start your complaint here as well, and we push it out to eFax by email, social media and printed letters.

How do I cancel eFax and get a refund?

To cancel eFax, follow the route on the How to cancel page of the eFax website or contact eFax support; the eFax customer agreement also allows a cancellation request by email to help@mail.efax.com. eFax plans renew automatically and fees are paid in advance, so ask for written confirmation of the cancellation and the date the service ends. If you want money back for a charge taken after you asked to cancel, or for pages you did not send, say so in the same request with the dates and amounts.

Keep the cancellation confirmation or the email you sent, every statement line reading CCSI EFAX, and the usage summary for any page charges.

Refused a refund on a plan you had already cancelled? Raise it through our complaint process: our trained AI opens a case for you and keeps coaching you on what to reply to eFax and when to push again.

Can I complain to my state attorney general about eFax?

Yes: in the United States, the consumer protection office or attorney general of your own state can help with complaints against businesses such as eFax, and may mediate complaints or investigate. It generally expects eFax to have had the chance to put things right first, so keep a record of every charge, cancellation request and reply.

Charged for a fax plan you cancelled? We help you write the complaint in minutes, with each date and statement line set out in order.

Is that eFax new fax email real?

Be careful. Emails dressed up as eFax fax notifications have long been used to spread harmful attachments or to send people to fake login pages that capture email passwords, and eFax has no part in them. Do not open the attachment or type in a password because of a fax you were not expecting.

What do people complain about most at eFax?

Nothing has been reported about eFax here yet. Our research shows what typically goes wrong at online fax services: automatic renewals of plans paid in advance, cancellations that are hard to complete, extra page charges on top of the plan, refunds refused for the rest of a paid period, and card lines such as CCSI EFAX that customers do not recognise.

Page charges you cannot match to your faxes? Be the first to report it: your case opens the record for the next subscriber checking an eFax bill.

What happens after I submit my complaint?

Your complaint gets its own public page on Complain.biz and we get to work: we bring it to the attention of eFax through emails, social media, paper complaint letters and other tools at our disposal.

And we stay with it after you file. Our trained AI opens a case file for you and keeps coaching: what to reply, when to push again, and how to escalate if nothing happens.

Can other consumers help me with my eFax complaint?

Yes. We have an active community of consumers, and complaints here are public: people who ran into the same problem with eFax can give you advice or back you up with their own story. A complaint with a community behind it is much harder to overlook.
