People and businesses have quickly transitioned from sending faxes using paper to automating the process using numbers linked to online faxes.

Since digital faxing solutions allow users to communicate online, they’re slowly replacing conventional faxing techniques.

For those who want to send faxes online but need help understanding the fundamentals of how it works, this article will discuss local and international number formats.

We’ll also discuss how to use digital fax.

Online fax number formats

The format of a fax number varies by country and region, so it’s crucial to know the difference when choosing one.

Here is what a fax number looks like:

1. International fax number format

To send faxes out of any country to another, you should always include this format: [+ or 011] [country code]-[area code or city code]-[local number].

A fax number example for international correspondence to a US number looks something like this: +1-907-555-1234.

From these digits, you can deduce that the recipient is in Alaska, USA.

2. Format for national fax numbers

If you’re sending faxes within the same country, you don’t need to include the country code.

For instance, with documents traveling inside the US, how to dial a fax number correctly simply requires typing only the area code and local number, i.e., 907-555-1234 for Alaska, though some carriers require a “1” in front: 1-907-555-1234. (But not a +1.)

3. Local format for sending faxes

When forwarding faxes within the same area code, you can add their numbers without the country and area codes.

A sample fax number for local transmission is 555-1234.

Analysis of fax numbers example

As shown earlier, fax numbers have three components: country codes, area codes, and local numbers.

But how long is a fax number in the US?

The typical US fax number is 11 digits long. Let’s use the number mentioned earlier [+1-907-555-1234] to analyze the main parts of a fax number.

Analysis of fax numbers example

Country Code

Every country has a unique dialing code, which always begins with the plus (+) sign followed by the number, indicating the recipient’s location.

Going by this sample, the dialing code will start with +1 to show that the recipient is in the USA.

Area Code

Area codes are unique to every state.

For example, 907 indicates that the fax machine is in Alaska.

If you don’t know the area code for your business, you can find it in an online directory or from your network provider.

Local Number

The local number is the third component of a fax number.

The numbers within a locality or district frequently consist of seven digits. From our previous example, 555-1234 is your local fax number.

How to create a fax number

As mentioned earlier, your network service provider can help you get your unique digits during activation.

Here is how to create an online number for your faxes.

  1. Contact your provider.
  2. Get your assigned number for the dialing codes of your country, state, and local municipality or section of the city. As we outlined above when explaining how many numbers are in a fax number, this process should be easy to complete and make perfect sense.
  3. Complete the registration by providing identification details like your name, SSN, and email.
  4. Verify and link your email address.

Four reasons to use an online fax service

Here are some reasons to use an online fax service.

They promote an eco-friendly environment

Companies are trying to minimize their carbon footprint, as part of the collective dedication to solve issues surrounding global warming and climate change.

However, traditional fax machines use paper, which is detrimental to the environment.

Unlike physical devices, online fax services have provided a more ecologically beneficial option since they eliminate the need for running through reams of paper.

They complement remote work

Moving a faxing device can be tedious when traveling to different locations.

But with digital services, users can communicate and share files from anywhere.

You don’t need to go to your home or office environment in order to send or receive faxes since they are always accessible on the go.

They boost productivity

You can automate many tedious tasks required for simple fax machines, such as scanning documents, thereby increasing productivity.

Also, online fax solutions provide users with cloud storage services and project management tools to help them efficiently track their materials.
