Welcome to the HP English Community --
Does your printer have fax hardware built into the printer?
If yes, then you have to connect the printer to a landline using a 2-wire phone cord.
Unless you have a separate Fax line coming into your house (provided by the phone company), the fax number would be the same as the phone line to which the phone cord is connected.
Every printer that has built-in Fax hardware also has an entire chapter in the user manual that is dedicated to "Fax".

What if?
If you have a DeskJet or another less expensive "not for business or small Office" printer, then your printer perhaps does not have built-in Fax hardware.
No Fax Hardware built into Printer = You have to use an electronic fax service.
HP offers -- still in Trial mode - HP Mobile Fax.
Mobile Fax can be used to Send faxes.
Unless something big changes, the service does not (at this writing) offer a Receive Fax service.
and
HP Mobile Fax does not need a Fax number because you cannot use it to Receive Faxes.
