825 Area Code: Edmonton, AB | Location & Time Zone

The 825 area code serves Alberta, Canada, covering major cities including Edmonton, Calgary, Red Deer, Lethbridge, and Medicine Hat. Introduced in 2016 as an overlay to the existing 403 and 587 area codes, 825 provides additional phone number capacity for Alberta’s growing population. This comprehensive guide covers everything you need to know about the 825 area code, including its geographic coverage, time zone information, dialing instructions, and history.

What is the 825 Area Code?

The 825 area code is a telephone area code in the North American Numbering Plan (NANP) that serves the entire province of Alberta, Canada. It was established on June 4, 2016, as an overlay area code, meaning it shares the same geographic region with the pre-existing 403 and 587 area codes. Unlike a geographic split where boundaries are divided, an overlay adds a new area code to the same territory, requiring 10-digit dialing for all calls within the region.

Alberta’s telecommunications system uses three area codes—403, 587, and 825—all covering the same geographic area throughout the province. This overlay system was implemented to meet the increasing demand for telephone numbers driven by population growth, the proliferation of mobile devices, and the expansion of business communication systems. The 825 area code ensures that Alberta has sufficient phone number resources for years to come.

History of 825 Area Code

When Was 825 Created?

The 825 area code was officially activated on June 4, 2016, by the Canadian Radio-television and Telecommunications Commission (CRTC). The implementation of 825 became necessary due to the depletion of available phone numbers in Alberta’s existing area codes. Alberta originally used only the 403 area code, which was one of the original area codes established in 1947 when the North American Numbering Plan was created. As Alberta’s population grew significantly through the 1990s and 2000s, particularly in the Calgary and Edmonton metropolitan areas, the demand for new phone numbers increased dramatically.

The introduction of 825 was preceded by extensive planning and public consultation. The CRTC announced the implementation timeline in advance to give residents and businesses time to prepare for the transition to mandatory 10-digit dialing. The decision to use an overlay rather than a geographic split was made to minimize disruption, as overlays allow existing phone numbers to remain unchanged while new numbers are assigned using the new area code.

Area Code Changes and Overlays

Alberta’s area code system has evolved through several stages. The original 403 area code served all of Alberta from 1947 until 1999. On January 25, 1999, the 780 area code was introduced as a geographic split, with northern Alberta (including Edmonton) receiving 780 while southern Alberta (including Calgary) retained 403. This split reflected the growing telecommunications needs of the province’s two major urban centers.

As both regions continued to grow, the 587 area code was introduced on September 19, 2008, as an overlay covering the entire province. This marked Alberta’s first experience with overlay area codes and mandatory 10-digit dialing. The 825 area code followed eight years later in 2016, becoming the third area code to serve Alberta. All three area codes—403, 587, and 825—now coexist throughout the province, with new phone numbers being assigned from any of the three codes depending on availability.

How to Call 825 Area Code

Dialing Within the Area Code

When making calls within Alberta, including calls within the 825 area code, you must use 10-digit dialing for all local calls. This requirement applies to all calls, regardless of whether you’re calling the same area code or a different one. The format is: 825-XXX-XXXX. You do not need to dial “1” before the area code for local calls within Alberta. Simply dial the three-digit area code followed by the seven-digit phone number. This applies whether you’re calling from a landline or mobile phone.

Dialing From Other Area Codes

When calling an 825 area code number from elsewhere in Canada or the United States, you must dial “1” followed by the area code and phone number. The format is: 1-825-XXX-XXXX. This is the standard North American long-distance dialing format. Long-distance charges may apply depending on your phone plan and the location from which you’re calling. Most modern mobile phone plans include Canada-wide calling, but it’s advisable to check with your service provider about potential charges.

International Dialing

When calling an 825 area code number from outside Canada and the United States, you must use the international dialing format. Start with your country’s international access code (often “00” or “+”), followed by Canada’s country code (1), then the area code and phone number. The format is: +1-825-XXX-XXXX. For example, from the United Kingdom, you would dial 00-1-825-XXX-XXXX. International calling rates will apply, and costs vary significantly by country and service provider. Many people find it more economical to use internet-based calling services or apps when making international calls.

Nearby Area Codes

It’s important to note that 403, 587, and 825 are overlay area codes that serve the same geographic region throughout Alberta. The 780 area code, while originally created as a geographic split in 1999, now also functions as part of the province-wide overlay system. Adjacent provinces and territories use different area codes, with Saskatchewan to the east, British Columbia to the west, and Canada’s northern territories to the north.

Population & Demographics

The 825 area code serves Alberta’s population of approximately 4.7 million people (as of 2024), making it Canada’s fourth most populous province. The population is concentrated primarily in two major metropolitan areas: Calgary (approximately 1.6 million in the metropolitan area) and Edmonton (approximately 1.5 million in the metropolitan area). These two cities account for more than two-thirds of the province’s total population and continue to experience steady growth.

Alberta has one of Canada’s youngest and most diverse populations, with significant immigration from other provinces and countries. The province’s economy, historically based on energy and agriculture, has diversified to include technology, finance, healthcare, education, and tourism. The oil and gas sector remains a major employer, particularly in Calgary, Edmonton, and Fort McMurray. Edmonton serves as the provincial capital and a major government, education, and healthcare hub, while Calgary is the commercial center with headquarters for many energy companies.

The region’s economic diversity and quality of life continue to attract new residents, driving the ongoing demand for telephone numbers and telecommunications infrastructure. The introduction of the 825 area code ensures that businesses and residents have access to sufficient phone numbers to support continued growth and technological advancement, including the proliferation of mobile devices, IoT applications, and business communication systems.
