Area codes in Canada

Canada uses 55 area codes, and the CRTC has approved three more. Type any three digits to see whether a code is Canadian, where it's used, which codes share its territory and what time it is there now. The data comes from Canada's numbering administrator and the North American plan's own database, both updated Oct. 7, 2026.

Every Canadian area code, by area

Canada's 55 area codes cover 18 areas. In most of them, several codes share the same ground: when an area starts to run short of numbers, the CRTC adds a new code on top of the old one instead of redrawing the map.^3,4 That's why Toronto has four codes and B.C. has six.

Codes in an area are listed oldest first. Cities are exchange areas in the administrator's listing.^1,2 Codes with a full guide are linked.

Three new area codes are coming

The CRTC approved three new codes in the past year, each for an area forecast to run out of numbers by 2029.^5,6,7 All three are overlays, the only method the CRTC now uses. Nobody has to change their number, and ten-digit local dialling is already in place in each area.^2,4

Existing customers keep their numbers. New lines in those areas can start getting the new code on or after its start date.

When each area could run out

Twice a year, carriers tell the Canadian Numbering Administrator how many numbers they expect to need. The administrator turns that into a projected exhaust date for each area.⁸ The July 2026 forecast puts eastern Quebec first, in November 2028, followed by Alberta, Nova Scotia and P.E.I., and the region around Toronto. The 905 area entered relief planning on Sept. 24, 2026.⁸

Projected exhaust dates from the administrator's status report posted Sept. 29, 2026, based on the July 2026 carrier forecast.⁸ "Beyond 2048" is the administrator's wording.

Six more codes are already earmarked. In November 2022 the CRTC set aside 537 for the 905 region and 460 for central and northeastern Ontario.⁹ In May 2025 it set aside 871 for eastern Ontario and 487 for southwestern Ontario.¹⁰ The administrator lists 387 as set aside for Toronto and says 926 is reserved for B.C.^3,8

Is it a Canadian number?

A +1 number isn't always Canadian. Canada shares the North American Numbering Plan with the United States, its territories and 18 Caribbean and Atlantic jurisdictions, from Bermuda to Trinidad and Tobago.² All of them use the same three-digit area code format, so 647 (Toronto), 646 (New York) and 649 (Turks and Caicos) look alike on a call display.²

Locations from the NANPA database file dated Oct. 7, 2026.² The lookup above covers every code in that file.

Toll-free codes such as 800, 833, 844, 855, 866, 877 and 888 work across the whole plan, so they don't point to a province or state.² Canada also has three non-geographic codes, 600, 622 and 633, for services that aren't tied to one place.^2,11

A familiar area code doesn't prove who's calling

The CRTC says callers can change what shows on your call display. Scammers copy the first six digits of your own number so a call looks local, display your own number, or borrow a real company's or government office's number.¹² The Canadian Anti-Fraud Centre's advice is never to assume the number on your screen is accurate.¹³

• Don't trust call display. The Canadian Anti-Fraud Centre says never to assume the number on your screen is accurate, for calls or texts.¹³
• Call back on a number you find yourself. If a caller says they're from your bank, a service provider, the police or a government agency, hang up and call the number on your card, your statement or the organization's website.^12,13
• Don't tap links in texts. Forward suspicious texts to 7726 (SPAM), then delete them.^13,14
• Report it. Report fraud to the Canadian Anti-Fraud Centre at 1-888-495-8501 or to your local police, even if you didn't lose money.^12,14
• Cut down on telemarketing. Register your number on the National Do Not Call List and file a complaint about unwanted telemarketing calls.¹²

Claims we checked

• False
  Since 647 arrived in 2001, the whole province of Ontario has used ten-digit dialling.

  Calilio's 647 page says "the Greater Toronto Area along with the whole province" switched to ten-digit dialling when 647 began.¹⁵ The administrator's history shows ten-digit local dialling came to Toronto with 647 in March 2001 and to the 905 area that June, but not to 613 and 819 until October 2006, or to southwestern Ontario until 226 arrived the same month.³

Questions people ask

How we did this

We built the lookup from two official files: the Canadian Numbering Administrator's exchange area listing and the NANPA area code database, both dated Oct. 7, 2026. Start dates come from NANPA and match the administrator's relief history. Projected exhaust dates come from the administrator's Sept. 29, 2026 status report, and new codes from the CRTC decisions that approved them. The clock works from fixed offsets and Canada's 2026 time rules (see our daylight saving time guide), not your device's settings. Sources were retrieved Oct. 7, 2026.

Area codes change slowly, but new codes, forecasts and time rules do move. Each change goes in the update log below.
