How to send fax from eFax to FaxExtension?

Send fax from eFax to FaxExtension using the FaxExtension cover page

eFax online fax service doesn’t support direct faxing to fax extension numbers, but you can send fax from eFax to FaxExtension by following these steps:

  1. Create the cover page using online tool and enter the recipient’s extension number.
  2. Save the created PDF document.
  3. Go to the eFax website or start the eFax mobile app and log in using your username and password.
  4. Create a new fax by choosing the appropriate option.
  5. Enter the recipient’s information, that’s FaxExtension main number +1 808-736-3329 (i.e. +1 808-SEND-FAX).
  6. Attach the cover page you created in the previous steps. Do NOT add the eFax cover page as this will override the FaxExtension cover page (it will not be the first page of your fax anymore).
  7. Hit Send.

This method only works for FaxExtension recipients with the main fax number +1 808-SEND-FAX (+1 808-736-3329). It may not work with other fax providers.
