What is my fax number is asked when a form demands one and the person has a machine in the corner or an online account they set up months ago and cannot remember. The number is always the one that answers: for a machine, the phone line it is plugged into; for an online service, the number listed in the account. This page shows how to find fax number in each place, how to confirm it is working with a test fax, and what to do if the honest answer is that there is no number yet.
Whats my fax number on an online account
Log in to the vendor's site or app and open the account or numbers page; every service lists the number or numbers assigned to the account there, and most print it at the top of the inbox as well. The same number appears in the header of every fax the account sends, so a copy of any sent fax shows it. If the account has more than one number, the one to give out is the one you want inbound pages delivered to; vendors allow routing rules per number. If the account was set up by someone else, the welcome email from the vendor carries the number, and the vendor's support desk can read it back against the account holder's details.
How to find fax number on a machine
Print the machine's settings or configuration page from its menu; the number entered at setup is printed there and in the header of outgoing pages. If nothing was entered, the machine has been sending with a blank header, and the number is the phone line's, which is on the phone bill or can be read by dialling out from a phone on that line to a mobile and reading the caller ID. On an office phone system, ask the administrator which external number is routed to the port the machine uses; the extension number is not reachable from outside. Then enter the number in the machine's settings so the header is right.
How to find my fax number when it does not exist
If there is no machine on a line and no online account, there is no fax number, and the form should be answered by getting one. An online plan assigns a number at sign-up that receives immediately: Fax.Plus prints one fax number included at $6.99 a month with 200 pages, CocoFax prints $9.99, MetroFax $11.95, iFax $12.49, WestFax $14.99 with 500 pages. Whichever route, confirm the number with a test: send a page to it from another service or a free sender and check it arrives, because the mistake that costs the most is giving out a number that nothing answers.
Questions people ask about what is my fax number
Is my fax number the same as my phone number?
Only if your fax runs on the same line with a switch or a service that handles both. A separate fax line or an online account has its own number.
Can I test my fax number for free?
Yes. Send a page to it from a free one-time sender and confirm it arrives in the machine tray or the online inbox. The timing page covers how long to wait.
I have an eFax or similar account; where is the number?
On the account page after login and in the header of any fax the account has sent. The welcome email from the vendor carries it too.
