Whether you’re sending a fax through a traditional fax machine or through an online service, you’ll still need the recipient’s fax number.

What is a Fax Number Lookup?

A fax number lookup helps you find the right fax number for various businesses and organizations. You might need to use a fax number lookup to:

• Check that you’re sending a fax to the right place
• Find the fax number for a particular company or person 
• Make sure your own fax number is listed correctly 

How to Find Your Fax Number

Sometimes, you might need to confirm or verify your own fax number. Here’s how to get a fax number for your own organization:

• Look at your old sent faxes to see if the sender’s number is listed on the fax header
• Check if your fax number is listed on your fax machine or in its settings

4 Ways To Find Fax Numbers

There are multiple ways to find a fax number. You may be able to contact the recipient directly, or you can also search the internet for a directory or the business’s website. The best method for you to lookup a fax number will depend on what information you already have. If you’re unsure how to find a fax number in your situation, the following methods will guide you.

1. Contact the Recipient

The simplest and most direct way to find a fax number is to contact the person or business directly and ask what their fax number is. If you can’t contact them directly, you will have to use one of the below fax number lookup methods.

2. Check Websites To Find a Fax Number Online

If you cannot reach out to the recipient to ask for their fax number, you can always rely on the internet. There are a couple of ways you can search online for a fax number.

Searching Websites With a Telephone Directory

Online telephone directories can be helpful when searching for a fax number. Directories are made to be easily searchable, so as long as you know the name of the person or business you need to contact, you can look up the directory for the appropriate fax number. Some sites include fax numbers alongside phone numbers, but if you can only find the phone number, you can also call the business and ask them for their fax number.

Many people use these directories specifically as a fax number lookup tool.

Navigating Business Websites for Fax Numbers

Most businesses have a website, and that website will usually contain the business’s contact information. The fax number will probably be located in the “Contact Us” section of their website. If no fax number is listed, you can likely find a phone number or email address to contact them for their fax number. You may be able to reach them via email or social media as well. 

3. Use Search Engines

To find a fax number via search engine, type the name of the business into the search field and add the phrase “fax number” after it. The search results may contain a fax number, but if you don’t see it, you may at least find their website or other contact information so you can ask for their fax number directly. 

4. Contact Your Fax Service Provider

Your fax service provider can also be of assistance when trying to find a fax number. If you need your own fax number, they can provide it to you. 

Requesting Fax Numbers for Incoming Faxes

Traditional incoming faxes will display the number that they were sent from on the Caller ID of the fax machine. If you are using an online fax service that doesn’t have identification included on it, you can contact the provider to request the number that the fax was sent from.   

Checking Sent Fax Documents for Fax Numbers

Most faxes you receive will include a cover sheet with contact information. A fax’s cover letter should have the identity of the sender, including their name or business name, the sender’s fax number, and the time and date. Even if the cover sheet doesn’t include the sender’s fax number, it can provide helpful information for your online search. 

If there is no cover sheet, you can check for the information within the header or footer of the document. With normal faxing, the number is included in the footer. If the fax has been sent within the United States, the first three digits are the area code, followed by the fax number. You should be able to locate a ten or eleven-digit number on each page. If the fax was sent internationally, the number of digits including the country code will depend on where it was sent from. 

If you received a document through an internet fax service or email faxing service, fax information may still be included in the footer. Scroll to the bottom of a page and lookup for the fax number there.
