What is a fax number?

Fax numbers are numbers used to send and receive faxes.

A fax number could look like a regular phone number format-wise. It is typically 10-digit long, with a 3-digit area or region code followed by a 7-digit unique identifier. You can obtain it from an online fax service provider or a telephone network company.

Hence, accuracy when dialing a fax phone number is critical for successful communication and timely delivery of important documents. This includes entering the area code if dialing internationally or prefix if sending a local fax. You must learn how to dial a fax number correctly so your document reaches the right recipient, avoiding delays and missed deadlines.

Dialing local fax numbers

When dialing a local fax number, you must make sure that you enter the area code or prefix for your region. This is typically done via the control panel of your fax machine. For example, in the US, you would add a “1” followed by the area code and then the number, such as 1-123-456-7890.

Dialing international or foreign fax numbers

For international or foreign fax numbers, you will need to make sure that you enter the country code first. This can also be done via the control panel on your fax machine or through the printer control panel if you’re using a multi-function printer with fax capabilities. For example, if you are dialing from the UK to the US, you need to enter “+1” followed by the area code and then the number. For example, +1-123-456-7890.

Manual Faxing vs. Digital Faxing

There are two main ways to dial a fax number: manually or using a computer or mobile phone. They differ in terms of:


Manual faxing is often more expensive, requiring equipment and paper, while online faxing can be done for free. When sending a fax manually, there are often additional fees for long-distance calls. But, when using a computer or mobile phone, you can often send faxes for free or lower costs, even if you dial a number outside your region.


Manual faxing requires access to a telephone line and a fax machine, whereas digital faxing requires internet access. Depending on your device (computer or mobile phone), you may need to install additional software or download an app.  Proper fax settings must be configured in both manual and digital methods, which can be guided by your fax provider.

Advantages and Disadvantages

Manual faxing advantages:

  • Can be used in areas with no internet access or unreliable connections.
  • No need for additional software or download of apps.

Manual faxing disadvantages:

  • Can be time-consuming and require manual labor.
  • Long-distance calls may be expensive.
  • Extra fees for extra paper or maintenance.

Digital faxing advantages:

  • No need for additional equipment or paper.
  • Can be done from anywhere with an internet connection.
  • No need for taking turns when using the fax machine.
  • Access to online fax services leveraging modern fax technology.

Digital faxing disadvantages:

  • Susceptible to viruses and other malicious software that can cause data loss or damage.
  • Not all fax users may have the same software or compatible hardware to receive digital faxes.
  • Also, in digital faxing, users need to ensure they correctly configure the fax header in their fax setup to ensure the recipient gets the correct information about the sender. This might require some technical know-how or guidance from the service provider.

Why Should You Go With An Online Faxing Service?

Nowadays, online faxing is becoming more and more popular among businesses. As mentioned earlier, it requires no additional hardware and can be done directly from your computer or mobile phone. Here are a few more advantages of using an online faxing solution.


You don’t have to be in the office or use a physical fax machine to send documents since you only need an internet connection and an online fax service. Additionally, a good fax service will provide easy fax settings management, contributing to a user-friendly experience.


Unlike manual faxing, digital transmissions arrive encrypted and can only be opened with authentication. This ensures that your documents remain secure during transit.  An effective online fax provider prioritizes such security features to ensure maximum confidentiality.


With digital transmissions, the risk of documents being lost in the mail or destroyed due to poor transmission quality is eliminated since digital files are sent through secure servers with guaranteed delivery times and complete accuracy.This reliability is a testament to the advantages of modern fax technology.


Many online fax providers, such as iFax, offer incredibly low fax rates. This makes it cost-effective for businesses of all sizes to adopt this technology. Also, you don’t need to pay for setup fees, overage charges, or maintenance costs as there’s no physical equipment involved when using an online solution.


Digital transmission speeds are much faster than manual transmissions via telephone lines. This means less time spent waiting for your essential documents to arrive at their destination safely.

As you can see, many benefits are associated with choosing an online faxing solution over traditional faxing and other paper-based methods. Online faxing is the way to go if you want a more efficient way of sending important documents.
