Frequently Asked Questions

A fax number is a unique number assigned to a specific fax machine, which enables the device to receive faxed documents. 

A fax number is a unique set of numbers used to contact your fax machine or your online fax account. A typical fax number consists of a country code, an area code, and your fax number.

To send a fax using a fax machine, you need to dial the fax number first like you would if you wish to make a phone call. Then you press send to fax your document. Then you attach the document you wish to transmit. Needless to say, online faxing is easier and more convenient.

Online faxing works the same way as sending an email, except you type in the recipient’s fax number instead of their email address. A fax number is the primary link between you and the recipient.

When you sign up for an online fax account here at iFax, you get your very own virtual fax number that you can use to send and receive documents. What’s even better is that this same convenient system also allows you to view and manage all of your received and sent faxes in one organized place.

The beauty of online faxing is that you no longer have to be confined to an office to send a fax to your clients or colleagues. A fax machine is no longer necessary. You also do not need to invest in fax servers or modems. And you do not need your own dedicated phone line. Online fax providers like iFax make it possible to transform your smartphone, tablet, or computer into your very own mobile fax machine.

With online faxing solutions, you still need a fax number to start sharing documents. But how do you get a fax number without an existing landline or phone line? Is that even possible? With iFax, it certainly is. When you sign up with iFax, you are entitled to get a free fax number. Once you have completed the account creation process, you then need to select your desired country code, city and/or area code, and fax number. You can also have multiple fax numbers using the same account. You might have to pay extra for the other online fax numbers.

If you already have an existing fax number, you also have the option to retain it by porting your old fax number to iFax. Porting a fax number means you do not have to update your contact information, ensuring a smooth communication flow between you and your clients.

Switching to an online fax service lets you enjoy the safety and convenience of traditional fax filing without the hassle of installing any bulky hardware and wires. Not only is it easy to use, but it is also a more cost-effective option.

To start sending documents via fax, you first need to have your own fax number. What does a fax number look like? A fax number looks exactly like your regular phone number. Both look like a unique series of numbers. A typical fax number usually contains your country code, your area code, and your fax number. Some fax numbers, on the other hand, do not contain an area code if you are only faxing locally.

So how long is a fax number? The length of your fax number depends on a number of factors. A local fax number is generally shorter than an international fax number. The latter contains additional digits called an exit code. An exit code ensures that your fax number reaches the international switchboard. Meanwhile, a toll-free fax number might also vary in length.

Fax Number Example:


Does a fax number on an online fax solution look different from that traditional fax number? Not entirely. Again, it depends on whether you created a local or international number for your fax service.

One of the most significant advantages of using an online faxing service is that you do not necessarily need a dedicated phone line to get your own fax number. Your fax providers usually assign your virtual fax number.

With iFax, you have the option to choose from our selection of free fax numbers. When you sign up with iFax, you can get your free fax number, even while on our time-limited free trial. You can generate a local fax number or a toll-free one if that’s what you prefer. You can create your online fax number after you have completed the account creation process.

Typically, a fax number consists of a country code, area code, and local subscriber number; the exact format can vary from one area/country to another.

When dialing a fax number, you can make it easy to read by including the area code in parentheses. You may use one of two punctuations – either a hyphen or a period – at the last number from your region’s phone area code. After inputting this information, insert space after closing parenthesis for the three-digit prefix followed afterward with another punctuation mark before writing down the last four digits of your fax number.

The fax number should look something like one of these:

  • (123) 456-7890
  • 123-456-7890
  • 123. 456.7890

The main difference between US and International fax number formats lies in the use of country codes.

If you are trying to send a fax in the United States, then it should consist of 10 digits: the three-digit area code plus the seven-digit phone number. It would look something like:


For this example, “212” is the area code, which is one of the area codes in the North American Numbering Plan (NANP) for most of the borough of Manhattan in New York City. While “823-7890” is the unique fax phone number of your recipient.

While North American fax numbers generally remain consistent in the number of digits used, those around the world vary widely. In fact, an international fax number could range from as few as 6 to over 9 digits.

When sending international fax, you will need to add additional information such as a country code and an international access code before your recipient’s subscriber number.

Depending on where you’re sending it, these codes can be one or two digits long (e.g., +1 for Canada or +85 for China). All countries have their own unique numerical prefix so that your international faxes don’t accidentally get sent somewhere else!

For instance, if you wanted to send a document to someone located in India with a local fax number 044 123 4567, your actual dialed fax number would be +91 44 123 4567 (+91 being India’s country coding prefix).

Generally speaking, each region will have its own set of rules regarding how to write out an international fax number correctly — some countries require hyphens or parentheses to separate numbers while others do not; furthermore, some countries require only one zero after their exit codes while others require two (or even three).

Additionally, different countries use different symbols and characters that represent local access codes; for example “00” is used by some European nations instead of “011”.

No matter what country your recipient is in though, always double-check with them first before attempting to transmit anything via fax just be sure that everything has been written down correctly.
