Can I port my current fax number to Sfax?

We get a number of inquiries from people wanting to port their current fax number instead of using a new toll free number. 

Porting a fax number to our service is definitely possible - we do it all the time. You will first want to confirm that your current carrier will release your number.  Most will, a few won’t. Once you've confirmed that, simply put in a support request and we will provide you with the LOA that you'll need to fill out to get started.  You will also need to provide a copy of your most recent bill.  We charge a one- time fee of $10 for each fax line, billed after porting is complete. 

Please note that we will not begin the porting process for you until you are out of your trial period.  You do have the option to end your trial period and become billable if you would like to start the process before your trial period is up.  The process can take anywhere from a two to four weeks, just depending on how responsive your carrier is, and how accurate the information you provide us with is.  Your carrier will require that your account billing is active and up to date before they will release the number(s), so DO NOT cancel your current account until you get confirmation from us that the number has been ported into our system. 

Another option is simply to forward your existing number to your Sfax toll-free number.  You will need to contact your current provider and they will be able to assist with setting up the forward of your current number to your Sfax toll-free number.  You will need to submit a support request providing the fax number you are forwarding from and the Sfax number you are forwarding to.  We will then program this on our side as well for delivery to your destination.

If you're ready to get started with the porting process, just submit a support request to and we will get right on it.
