<h2 style=”text-align: center;”>403 ARE CODE NUMBER: LOCATION, CITIES, MAP AND TIME ZONE</h2>

Nearly 70 years ago, back in 1949, it was decided that 89 unique area codes would be assigned to the US states and the then nine provinces of Canada. Area code 403 was one of them. There were a total of 89 [In the beginning there were a total of 86 Area assigned by the AT&T (or Bell Telephone) 9 in Canada and 77 for Continental US] area codes at their launch. Area Codes were rather introduced in 1947 and although Canada only had 9 provinces at the time (Newfoundland and Labrador was technically not part of the Confederation until the next year in 1948), it participated in the North American Numbering Plan of the time; thus, it was included as part of the Original Area Code 902

The History of the 403 Area Code

The concept of having a telephone in the home – and certainly in the office – was no longer a new one at that point when these new area codes were introduced via the North American Numbering Plan. The NANP, as it was known, was a response to the way the and telephone system in North America had expanded, designed to improve the way it functioned for everyone, businesses and residential customers alike.

Originally, when it was introduced in 1947, the 403 area code was assigned to all of the telephones in the whole province of Alberta, but later, circa 1960, a physical boundary extension started to occur as the Yukon, the southern & western parts of the Northwest Territories began to interconnect to the Public Switch Telephone Network and use Alberta 403 area code the Yukon and the western half of the Northwest Territories, a lot of area to cover indeed. It stayed that way for many years, until 1997. At that point, the Northwest Territories were given their own area code, 867 (which spells TOP as a reference to this region geographic situation), and then just two years later two thirds of Alberta’s telephones were reassigned to the brand new 780 area code.

As we mentioned earlier, it’s still a pretty big area! And an area that contains some of the most vibrant and interesting places in the Alberta Province. Let’s look at some of them:


Alberta’s largest city and Canada’s third largest municipality, Calgary is a beautiful, lively and rather unique city that nestles in an area of prairie and foothills that is fed by the Bow and Elbow Rivers. It’s home to the second largest number of major corporate offices in Canada, and those companies include representatives of the energy, film and television, financial services, transportation, technology, manufacturing, aerospace, health and wellness and a growing tourism industry.

For many businesses then a 403 area code could be said to be something of a mark of prestige, much like the famous 212 area code in Manhattan, New York down in the United States. It’s a mark of a company that’s doing business in a city that has earned the respect of consumers and other businesses globally – and has even hosted a Winter Olympics, so it’s no surprise that being assigned a 403 code is a plus that many businesses appreciate.

Calgary also boasts many exciting attractions and entertainments, including all of the following:


  • Canada Sports Hall of Fame
  • Canada Olympic Park
  • The Devonian Indoor Gardens – the second largest urban indoor garden in the world
  • The Calgary Tower – the tallest structure in Canada outside Toronto
  • The Calgary Zoo
  • 17 Avenue – An area filled with bars, nightclubs and theatres

When a business chooses to call Calgary its base of operations that means it’s looking to become a part of a lively, fast growing economy that welcomes companies from all niches, of all sizes and from all over the world. Having an efficient business telephone system in place is a must, and having it tied to the 403 area code is an easy and effective way to build that business’ connection with Stampede City, as the locals call it.


When the people of Calgary want to escape from the city, and from the hustle and bustle of city life, many of them head for the mountain resort town of Banff.

Although it’s very much in vogue today, there has been a resort of one kind or another in Banff since the late 1890s. In the 1880s, a trio of Canadian Pacific Railroad workers almost literally stumbled on a series of natural hot springs. These served as the foundation for a mountain retreat that has been popular ever since.

Although Banff is located outside the city, and can feel like it’s a world away, it does still share the 403 area code with its busier neighbour. While not home to major corporations Banff does boast many major retail outlets as well as many niche businesses who cater both to the locals and to the thousands of tourists that arrive every year.

Maintaining the same 403 area code as the larger City of Calgary often means that even those who have never heard of the slightly oddly named leisure spot can often figure out where it’s located without the need for a map, or Google, somehing that businesses can use to their advantage.

Red Deer

Red Deer is a rather unique city, one that is known as the ‘Cultural Capital of Canada’. It gained this nickname as since its founding it has been a beacon for many of the immigrants who have made their way to Canada in search of a new life and because of that it is one of the most diverse cities in Canada.

The very diverse demographic is represented in terms of business and culture in Red Deer. The city is home to Central Alberta Theatre, Ignition Theatre, Central Music Festival, the Red Deer Symphony Orchestra, the Red Deer Museum and Art Gallery and to businesses from all over the world.

Red Deer is now however being split into two area codes – 403 and the newer 587, so those wishing to keep their 403 status while upgrading their phone systems should do so soon!

Black Diamond

As you might have guessed from the name of this unique Alberta town, Black Diamond was founded to house those who came to the area to mine black diamonds’, more commonly known as coal.

The coal mines are no longer operational – although they can be visited for educational purposes, and so the town found a new purpose; an adventure destination for tourists.

This section of the 403 area code now offers hiking and biking trails, water trails, skateboard parks and more, as well as serving for a haven for working artists. It is also thriving as a small residential town, offering the peace of rural living but, as its inclusion in the area code 403 denotes is still close to the big city of Calgary.

Why is Your Area Code Important?

With all of this talk about area codes you might be wondering why it should even be discussed. After all, it’s just a number. However, the area code attached to you phone number is important, especially if you are running a business.

The fact is that most people attach as much significance to an area code as they do to a zip code. Both numbers indicate that the owner of a phone number belongs to a certain community. And where location is important for any business, area codes help reinforce it, and that is something that can be especially important to a business that relies on local consumers.

Is Your Telephone System Up to the Challenge of the 21st Century?

And while we’re discussing area codes it only makes sense to discuss telephone systems themselves. Even with the Internet, email, and instant messaging playing a big part in the operation of businesses these days an efficient telephone system is still its lifeblood. An old-fashioned telephone system is often not up to the task though.

In the 21st century customers and clients expect to call a business and be connected to the resources they are looking for quickly and efficiently. They don’t expect to encounter long wait times, disconnections or poor call routing. They like to be able to leave messages out of business hours, have their calls directed to the right party quickly and handled in the right manner. And to achieve all of this puts a serious strain on a standard telephone system.

A cloud based telephone system is a different matter though. Here are just some of the advantages it has to offer:

  • It’s not limited by local phone wires and cabling and if a problem occurs it can be fixed remotely, with no waiting hours and hours for a repairman to arrive.
  • As a business grows and expands its phone system can be expanded quickly and easily and with minimal cost.
  • Businesses can monitor call usage, both incoming and outgoing, for both better economy and better compliance.
  • A cloud based phone system also offers secure faxing, text messaging, video and audio conferencing and more.
  • Employees can stay in the loop even when out of the office, by making use of the mobile phones to connect to the cloud and answer their phone, or participate in a meeting, as easily as they could if they were sitting at their desk.
  • Make use of auto attendants and IVRs to streamline call routing to meet the expectations of busy customers and clients.

If your business operates in the 403-area code you’ll need to be able to continue to do so. Our system will allow you to get the upgraded phone system you need while keeping the 403 area code you love. And if you don’t maintain an office in the 403 area code physically, you could still get a 403 number to help you better appeal to consumers in that area.

These opportunities are limited however, so signing up today is the best way to ensure that you get ahead of your competitors, both by offering a more efficient communications experience to your clients and employees and maintaining  the identity, and the prestige, that the 403 area code provides you with.
