How to Find Fax Number on Printer

Most people wouldn’t think to look for a fax number on their printer, but in today’s digital world, faxing is still an important communication tool.

If you need to send or receive a fax, you’ll need to know where to find the fax number on your printer. Here’s how to locate it!

How to Find Your Fax Machine Number

Even though fax machines are still important to many people, it can be hard to remember the number for your fax machine. It’s important to know your fax machine number in case you need to send a fax to yourself or someone else.

The fax number for a fax machine or computer is the phone number of the attached phone line. To find out the fax number, call toll-free 1-800-444-4444 (operated by MCI).

You can also use the fax machine to dial a phone number and see what number shows up on the caller id. The number that appears is the fax number that the fax is currently using.

An online fax service will give you a fax number. You can find this number by logging in to the service and checking your account settings.

Fax machines have a setting for the fax number that appears as the header on all faxes that it sends. This information is called CSID (Customer Service Identification) and TSID (Transmission Service Identification).

If your fax machine changes its fax number, make sure to update the CSID and TSID information on the machine. If you don’t, the machine will print the old fax number in the header information of the faxes it sends, and on confirmation pages it prints.
