What Is a Fax Number, and How To Use It? Find Out With DoNotPay

If you need to send classified legal or medical files, you shouldn’t resort to email. Faxing is the way to go—it provides the necessary security measures by encrypting the document during the transfer.

Faxing requires the use of a fax number. “What is a fax number?” you may ask. DoNotPay will answer that and many other faxing questions in this article!

Fax Number Definition

A fax number is a number used to contact a fax machine, a fax server, or an online fax provider. It looks like a regular telephone number. The only difference is that when you dial a fax number, a fax tone answers. 

Fax numbers are assigned by a phone company or an online fax provider to ensure faxes will reach their destination.

Fax numbers are defined according to:

  • Format
  • Number of digits

How Long Is a Fax Number?

The length of a fax number varies based on:

  1. The location of the recipient—you can send faxes locally or internationally 
  2. The country—different countries have different phone number length, and the same goes for fax numbers

For faxing outside of your local area, you will need to add a country and an area code at the beginning of your fax number. The country code for the U.S. is the number 1. The area code typically has three digits. After entering the country and area code, respectively, the fax number follows. The fax number for the U.S. consists of seven digits, typically in groups of three and four. 

If you are faxing to another country, a fax number will be even longer. The additional digits are called the exit codes and are there to ensure the number reaches the international switchboard. The exit codes vary based on the sender’s and receiver’s country. The U.S. exit code is 011.

You need to make sure all the requirements are met before sending the fax to a specific location. After adding the required codes, the fax number can expand to over ten digits, depending on its destination. 

What Is a Standard Fax Number Format?

Fax numbers have a standard format, depending on whether you are sending faxes locally or internationally. Take a look at the table below to see typical fax number formats:
