587 Area Code 6 Top Alberta Secrets Revealed

The 587 area code is a telephone overlay code covering the entire province of Alberta, Canada. It shares the same geographic territory as area codes 403, 780, and 825, meaning callers in cities like Calgary, Edmonton, and Red Deer may dial a number starting with 587 even if their own line uses a different code. Ten-digit dialing is mandatory throughout the region.

What Is the 587 Area Code?

A 587 area code number belongs to Alberta’s overlay system, a setup the Canadian Radio-television and Telecommunications Commission approved to stretch out the province’s shrinking supply of phone numbers. Rather than splitting the province into new geographic zones (which forces people to change numbers), regulators layered a fresh code directly on top of the existing ones. That’s why a business in Calgary might have a 403 landline and a 587 mobile number registered at the exact same address.

In our experience helping small businesses set up virtual numbers, this overlay structure confuses people at first. They assume the code tells you something precise about location, the way an old-style split once did. It doesn’t, not anymore. What it does tell you is that the number was issued somewhere in Alberta, full stop.

Where Is the 587 Area Code Located?

The 587 code covers the whole province, not a single city or corner of it. That’s the part most directories get wrong when they try to pin it to “northern” or “southern” Alberta specifically.

Cities and Regions Covered

Numbers under this code are active across:

  • Calgary and the surrounding Foothills region
  • Edmonton and nearby communities like St. Albert, Sherwood Park, and Spruce Grove
  • Red Deer, Lacombe, and Ponoka in central Alberta
  • Lethbridge, Medicine Hat, and Taber in the south
  • Fort McMurray and Grande Prairie in the north
  • Smaller towns including Airdrie, Cochrane, Canmore, Banff, and Strathmore

Because the overlay applies province-wide, a 587 number in Canmore and one in Fort McMurray are dialled the exact same way from anywhere else in Alberta. There’s no local prefix logic left to decode.

How Did the 587 Area Code Come to Be?

Alberta originally ran on one single code, 403, assigned back in 1947 alongside the first wave of North American area codes. For decades, that single code covered the entire province plus the territories. Growth changed everything. By January 1999, regulators split the province in two, handing Edmonton and the north a new code, 780, while Calgary and the south kept 403.

Even that split didn’t hold for long. Cell phones, fax lines, and second house hold numbers ate through the available blocks faster than anyone expected, so instead of splitting the map again, Alberta got its first overlay on September 19, 2008: the 587 area code. Ten-digit dialing became mandatory that same year across the whole province, a genuine inconvenience at first, though most callers stopped noticing within a few months.

Demand kept climbing. Alberta added 825 in April 2016 and 368 in January 2022, both overlaying the same territory as 403, 587, and 780. A sixth code, 568, is currently reserved for future use once the others near capacity again.

Is the 587 Area Code Toll-Free?

No. A 587 area code number is a standard local Alberta line, not a toll-free number. Toll-free ranges in Canada start with 800, 833, 844, 855, 866, 877, or 888 instead. If you’re calling a 587 number from outside Alberta, standard long-distance rates from your plan will apply, the same as calling any other regular ten-digit Canadian number.

Why Am I Getting Spam Calls From a 587 Area Code Number?

This is genuinely one of the most common complaints tied to the code, and we hear it constantly from Alberta clients. Scammers frequently spoof numbers that share the recipient’s own area code and even the first three local digits, betting that a familiar-looking number gets answered when an unknown one wouldn’t.

A few practical fixes that actually work:

  • Ask your carrier about built-in call screening; several major Canadian providers offer a feature that requires unknown callers to confirm themselves before your phone rings.
  • Enable spam filtering on Android or restrict ringing to saved contacts on iPhone.
  • Never share banking details, social insurance numbers, or account passwords with an unsolicited caller, even one claiming to represent a government department or financial institution.

None of these tricks make spam disappear entirely, but they cut the volume down noticeably within a week or two, based on what we’ve seen with clients who switched on carrier-level filtering.

What Time Zone Does the 587 Area Code Use?

Alberta sits in the Mountain Time zone, so every 587 number operates on MST (UTC-07:00) during winter and shifts to MDT (UTC-06:00) when daylight saving time begins in spring. This applies uniformly across the whole overlay, whether the call originates in Calgary or a smaller town near the Saskatchewan border.
