How RingCentral online fax works

How to send a fax online

Create a "new fax" in the RingCentral mobile or desktop app and enter the recipient's fax number, add message text, and attach files from DropBox, Box, Google Drive, or any Microsoft Office® application.


Or, submit faxes online via email by addressing them to the recipient's fax number @rcfax.com. The email text and any attachments become the pages of the fax.

How to receive a fax online

RingCentral will provide you with your own fax number or you can use your existing number. You'll receive internet faxes in your inbox as email attachments that you can forward, file, or print.

Eliminate costly hardware and dedicated phone lines

  • No need for a fax machine—all incoming faxes are handled online.
  • No separate fax number needed, either—every RingCentral extension can receive both voice calls and faxes.

Send a fax using multiple methods —including email-to-fax

  • Send a fax online, directly from your email. Just attach files, add a cover letter, and you’re good to go.
  • Attach files from your computer or from cloud storage (Box, Dropbox™, Google Drive™), and send faxes directly using FaxOut.
  • Use the RingCentral mobile app to send faxes from anywhere.

Never miss a fax or call

  • Get instant notifications by text, email, or the desktop app whenever you receive an incoming fax.
  • Callers never hear a busy signal. Even if you’re on the phone or receiving a fax transmission, you’ll still receive your faxes.

Ensure maximum control and security for your online faxes

  • Preview, print, and annotate faxes, and design custom cover sheets—right from your computer.
  • Transmit faxes securely over an encrypted connection.
  • Incoming faxes are stored securely in your account and can be delivered as email attachments.
  • Fax to groups, block faxes without caller ID, schedule faxes, and more.
“RingCentral is way ahead in terms of innovation. It has plenty of functionality: it brings big-company systems to smaller companies.”

Chief Executive Officer, Walker Crips Group PLC
