Fax Number Porting

Keep your current fax number and migrate to the most advanced online faxing solution. To port your current fax number(s) to Fax.Plus, please fill out our Porting Request Form.

Once your porting request is received, and your fax number is confirmed, the following documents will be requested from you:

A completed and signed Letter of Authorization (LOA) form

This country-specific form will be provided by our Support team once we receive your porting request.

The last invoice of your current fax number

This invoice is essential to verify ownership of your current fax number. Please include a summary copy displaying your name and your current fax number.

Process for Pre-Porting

You will receive a temporary fax number, and depending on the country you are porting your number from, you may need to upgrade to a different plan. For instance, if you are porting a fax number from the United States, you will need to upgrade to Premium or a higher plan.

Process for Initiating Porting

Once we have received the required documents and are informed of your plan upgrade, we will begin the porting process to transfer your number into our service. You will receive notifications about the progress of the process accordingly.


Once the porting process is complete, your previously owned fax number will be assigned to your Fax.Plus account, and the temporary number provided during the pre-porting stage will be removed.


If you wish to keep both your temporarily assigned number and your ported number within a single account, you can simply upgrade your plan to Business or Enterprise.
