The Canada.ca style
The Government of Canada style guide writes phone numbers with hyphens, no brackets, and a spelled-out extension.
613-999-9900 ext. 123
Hyphens between the three groups. Extension written as “ext.” and a space.
613-999-9900 poste 123
Même mise en forme, avec « poste » pour l’extension.
+16139999900
International form for forms and databases: plus sign, country code 1, ten digits, no separators.
Area codes by province
The geographic area codes in service in the CNAC table. Type a number above to highlight its row.
| Province or territory | Area codes |
|---|---|
| Manitoba | 204 · 431 · 584 |
| Ontario | 226 · 249 · 289 · 343 · 365 · 382 · 416 · 437 · 519 · 548 · 613 · 647 · 683 · 705 · 742 · 753 · 807 · 905 · 942 |
| British Columbia | 236 · 250 · 257 · 604 · 672 · 778 |
| Quebec | 263 · 354 · 367 · 418 · 438 · 450 · 468 · 514 · 579 · 581 · 819 · 873 |
| Saskatchewan | 306 · 474 · 639 |
| Alberta | 368 · 403 · 587 · 780 · 825 |
| New Brunswick | 428 · 506 |
| Newfoundland and Labrador | 709 · 879 |
| Nova Scotia / Prince Edward Island | 782 · 902 |
| Yukon / Northwest Territories / Nunavut | 867 |
Announced but not in service
These codes appear in the CNAC table but are not in service, so the formatter treats them as unassigned.
| 273 | Quebec | February 2027 |
| 851 | Nova Scotia and Prince Edward Island | February 2028 |
| 568 | Alberta | date not set |
| 387 | Ontario | set aside |
The table lists 55 codes; its own footer says 56, and we could not reconcile the difference. Area codes also change by overlay, so check the CNAC for a new one.
Frequently asked questions
Is the number I type sent anywhere?
No. The formatting is a few lines of JavaScript on this page. Nothing is sent, stored or logged.
Does the area code tell me where the person is?
Only roughly, and only where the number was first assigned. Mobile numbers move with their owners, so the province is where the area code belongs, not where the phone is.
Why does 902 show two provinces?
Nova Scotia and Prince Edward Island share area codes 902 and 782. Likewise 867 serves Yukon, the Northwest Territories and Nunavut together.
Does it work for US numbers?
It formats any ten-digit North American number, but the province lookup only knows Canadian area codes. A US code is flagged as not on the Canadian list.
What about toll-free numbers?
A toll-free number such as 1-800 is written in the same pattern and formats fine, but it has no province, and this tool marks it as not on the Canadian list.

How we check it
The area code table is compared with the CNAC history table, including the count per province (Ontario 19, Quebec 12, British Columbia 6, Alberta 5) and the four codes not yet in service.
Formatting is tested on seven common writings of one number, on extensions in English and French, and on rejection of the wrong length and leading digits.
Limits: we apply the Canada.ca style as we read it, without a separate implementation to compare against. The CNAC footer total differs from the number of rows by one. We do not check whether a number is in service, and toll-free and special codes are not recognised as Canadian.
