Sending and receiving faxes with a fax extension

What is a fax extension?

A fax extension is no different than any other phone number extension. With a fax extension, you share a fax number with others, but you have an extension that you can use to send and receive faxes. So, your own fax number with the extension looks like: +1 808-SEND-FAX #123456 (or +1 808-736-3329 #123456).

How does it work?

Sending faxes

The recipient will see a fax number you share with others when you send a fax. However, FaxExtension will automatically add your fax extension information to the cover page and header. This way, the recipient of your fax will know where to send a reply.

You can get a free FaxExtension number right now. Besides faxing to any fax number, this extension allows free faxing between FaxExtension users.

Receiving faxes

When somebody sends a fax to you, they must dial your shared fax number first and then your fax extension. It is as easy as calling someone on their phone number extension. Most modern fax machines have support for fax number extensions.

We will send you an email notification every time you receive a fax to your fax number extension, and you will be able to see and download the received fax in FaxExtension email-like online portal.
