A fax machine sends documents electronically using a phone line, but in order to send documents, you must know the receiver’s fax number. Whether you’re looking for a business’ fax number or trying to locate your own, we’ve got you covered! Keep reading to learn how to find a fax number for any business or fax machine.

Things You Should Know

  • Locate a business’ fax number by looking under the “Contact Us” tab of their website. This page typically lists all means of contact for the business.
  • If no fax number is listed on a company’s website, call the business directly and ask for their fax number.
  • Find your own fax number by using your fax machine to call your cell phone. The number that pops up on your cell is your fax number.

  1. Go to the company website you want to fax and look for the “Contact Us” section. Click on this to see what contact options are available. While not all companies do this, many businesses and organizations will list their fax number directly, along with phone numbers and email addresses.
    • If you are unsure of what the business’ website is, type the business name into an online search engine, like Google.
  2. Use a search engine of your choice and type in the business name. Add “fax number” after the business name to specify your search and press “enter.” Then, skim through the search results to see if their fax number is listed on another website.
    • For example, you may find the business’ “Contact Us” page listing their fax number.
    • You can also use phone directory websites to find fax numbers. These are particular sites that have a directory of fax numbers across many different types of businesses. Simply search “phone directory” online and select a website to start.

  3. Sometimes, it’s best to go directly to the source. Call, email, or private message the business and ask for their fax number. Then, wait for a response.
    • Calling is typically a more direct way to get in contact with a business, so opt for a phone call first.

  1. Use the fax machine itself to call a landline phone or smartphone with caller ID. Check the caller ID on your phone to see what number comes up. The number displayed after the phone connects is your fax number.
    • For example, if you don’t know the number of your work fax machine, call your personal cell phone with the machine. Then, write down the fax number as listed on your phone.
  2. An online fax service is a third-party company that charges a small fee to use a personalized fax line, such as efax.com . Type in your username and password to log in and go into your account settings. Then, click your account settings tab and find the fax number listed on this page.

How do you reverse search a fax number?

PDF download Download Article
  1. On the printed page, look across the top or bottom of the page for a 10-digit phone number. In addition, look at the display screen on the fax machine and select “recent faxes.” Scroll through the most recent faxes to find the number you want to trace.
    • When you do this, try to get the area code as well. This helps you narrow down your options as you search for the correct line.
  2. Online telephone directories offer information much like a phone book, but they often have a much wider range of information. [1] Search online for “telephone directory” and browse your options. Make your decision based on which directories offer reverse phone number searches.
    • A reverse number search is where you use a phone number to locate the name of a business or individual, rather than searching with the name to find the number.
  3. When you go to the directory’s website, look for the “Reverse Phone” tab. Click the tab, type your fax number into the search bar, and press “enter.” [2] The window that pops up lists any relevant information tied to that phone number, such as a name and address.
    • If the fax number is tied to a business, the company name and address is usually listed.
    • If the fax number is tied to a personal fax machine, you may receive information on the owner or phone line carrier provider.

What is a fax number?

  1. This number looks exactly like a regular phone number; however, rather than calling a phone, it calls a fax machine. Fax machines are used to send and receive information. Offices often use these machines to pass along important documents or printed memos. [3]
    • When a fax machine is plugged into a landline, it turns the landline telephone number into a fax number as it adopts the number to be used for sending and receiving information. [4]
    • Unlike phone numbers, fax numbers don’t necessarily need a geographic area code.
    • A fax machine is a phone, scanner, and printer all rolled into one, allowing users to send and receive paper documentation.

    Your fax number is the same telephone number that you connected the fax machine to. If you only have one number, it's the same as the voice number. If it is a separate line, then use the fax to call someone that has caller ID, and they can tell you the number the fax is dialing from.

  • Question
    Is my landline phone number the same as my fax number?
    Community Answer
    Not always, but it could be. If you only have one telephone line, then your landline number could also be your fax number.
