So how does a fax number work? Well, a fax number is actually a phone number that is used to send faxes. When sending a fax domestically or internationally, you will need to be aware of the different formats – for example, the US uses +1-907-555-1234, while the UK uses +44-20-1224-3456. Did you know that fax numbers can look different depending on where you’re sending them? For local faxing in the US, you may only require 7 digits if you’re faxing within your state. If you’re faxing to another state, you can just add the area code!
If you need to fax to another country, that’s easy! International fax numbers include a country code – just add +1 for the US or +44 for the UK. The plus sign is your “international passport” for faxing across borders!
So, let’s talk about how fax numbers can help you send your documents on their way. Similar to a GPS coordinate, fax numbers use a combination of geographic location codes to ensure that documents are delivered to the correct address. It’s like a map for your fax!
How Fax Numbers Work
Your fax number will be very similar to your phone number – they are closely related! Standard fax numbers usually consist of an area code and seven more digits in most areas. Each number serves a purpose – the first few digits will indicate where the fax is going, and the remainder of the digits will reference the fax machine. A fun fact – modern fax lines can also make regular calls, in addition to fax transmission. It’s like a dual number!
Here’s how they work. Each number in your fax number has a purpose. The first few numbers help to direct your fax to the correct geographic region, and the remaining numbers ensure that it reaches the specific fax line you are trying to reach. You’ll notice that modern fax systems are capable of sending both voice calls as well as fax transmissions over the same phone line. This means that you can use the same number to make phone calls and to send faxes, which can be convenient.
Sending Faxes Locally vs. Internationally
Local fax numbers look similar to the regular phone numbers you dial every day – they are the same as your local phone numbers. So if you’re in the United States, U.S. local fax numbers look like this: (555) 123-4567. Sending an international fax? You’ll need to include a country code at the beginning. For example, faxing to the U.S. requires +1, while faxing to the UK requires +44. These codes are to ensure your fax reaches the correct country.
Different countries have different formats for their fax numbers. Some countries have shorter local numbers, while other countries require additional digits to ensure that everything is routed correctly. Be sure to double check the requirements for the country you are faxing to!
Fax Number Formats by Region
U.S. fax numbers follow a consistent pattern:
- Local: 7 digits (123-4567)
- National: 10 digits (208-123-4567)
- International: 11+ digits (+1-208-123-4567)
European fax numbers vary by country:
- UK: +44 followed by 9-10 digits
- Germany: +49 plus regional codes
- France: +33 with department codes
Asian regions often use different lengths:
- Japan: +81 plus city code
- China: +86 with area codes
- South Korea: +82 followed by region codes
Getting Your Own Fax Number
When you’re ready to get a fax number, you’re going to have two options to choose from. You can get a local number (which is assigned to a specific area, just like a traditional phone number) or a toll-free number (which starts with well-known prefixes, such as 800, 888, or 877). Need the fastest way to get started? Most online fax providers can give you a number right away. You will be able to choose a number in your local area code, or alternatively, you can choose a toll-free number for your business.
Fax numbers have a standard format, just like phone numbers – for example, if you are in the US, you will have a 3-digit area code followed by a 7-digit number. If you are faxing internationally, you will also need to include country codes (e.g. +1 for the United States).
Using Your Fax Number the Right Way
Do you want to know how to format your fax number in a way that will ensure your faxes connect? Here’s how to use your fax number: For local faxes, simply dial the full 10 digits of the fax number. For international faxes, include the country code and exit code where applicable.
When including your fax number on business materials, format it in this way:* Local: (555) 123-4567
- Toll-free: 1-800-123-4567
- International: +1-555-123-4567
Did you know? If you’re using a digital fax service, they will make the process even easier for you, such as automatically formatting your faxes, or making it easy to click-to-fax without having to type in a number (which you might accidentally get wrong!).

Want to send and receive faxes? Online faxing is a breeze – you can do it from your phone, computer or tablet! Unlike traditional fax machines, an online fax service provides you with extra security features and more convenience (no more waiting by the fax machine!)
Creating and Managing Online Fax Numbers
But did you know you can get started with digital faxing in just a few minutes? You’ll have options – you might want a local number, or perhaps a toll-free number would be better for you. A digital fax number is like a regular phone number, but it’s a dedicated fax number! You can access it anywhere, from your phone fax app, your email or even through a website.
Already have a fax number? No problem! Most digital fax services allow you to keep your existing number – they will help transfer the number to their online service (this is called number porting). Here’s how easy it is to get started:
- Select your fax number type (local numbers are generally used by most people, but a toll-free fax number adds a professional touch to your business)
- Browse available numbers and select one that you like
- Confirm your contact details (make sure that everything is correct)
- You can start faxing immediately!
But the best thing about digital fax numbers is that they offer lots of useful features. Spam filtering will block junk faxes, cloud storage will ensure that your faxes are backed up and easily accessible, and automatic notifications will alert you when a new fax is received! You can also use multiple fax numbers in one place – so you don’t need to use different services or machines!
The Bottom Line
At its core, a fax number is simply a specialized phone number that guides your documents to their destination. The format varies by location – in the US, it’s +1-907-555-1234, while the UK uses +44-20-1224-3456. For local faxing, you might only need 7 digits, but crossing state or country lines requires additional codes.
What matters most? Three key things:
- Local numbers work just like regular phone numbers
- International faxes need country codes (like +1 for US)
- Digital faxing makes the whole process simpler
