How do I find my fax number?

Your fax number is the number to call your fax. It looks exactly like a regular phone number.

With a fax machine or computer running fax software, the fax number is the phone number of the attached phone line. Calling the toll-free number 1-800-444-4444 (operated by MCI) will tell you the line’s phone number.

With an online fax service, the fax number is the number assigned by the fax provider. Log in to the service and check settings to see the fax number assigned to your account.
