What is a fax number?

A fax number is a unique telephone number used to send and receive fax transmissions. Fax machines allow users to send paper documents electronically over a telephone network. The receiving fax machine converts the transmitted data into a printed document. Fax numbers are typically formatted like regular telephone numbers, with a country code, area code, and local number. Fax numbers can be assigned to businesses and individuals by telecommunications providers, and can be used to send important documents such as contracts, invoices, and legal paperwork. Fax numbers can also be utilized in conjunction with computer software and online services that allow for electronic faxing.
