Whitehorse’s share of its area code

Within area code 867, Whitehorse takes 30 of 258 prefixes (11.6%), a substantial slice of a code shared by 75 rate centres, the largest of them Yellowknife.

Who holds these numbers

Iristel Inc. holds the largest share at 13 prefixes, 43.3% of the total, ahead of 4 other carriers. Code by code: in 867, Iristel Inc. leads with 13 of 30 prefixes ahead of 4 others.

Wireless and wireline

10 of Whitehorse’s 30 prefixes (33.3%) are held by carriers whose registered name marks a wireless business: Bell Mobility, TELUS Mobility and Ice Wireless Inc. Wireline prefixes still outnumber them, carried by Iristel Inc and Northwestel. This is a sort by name, not a licence lookup, and a mobile prefix may have been ported to another network since.

How the allocation was built up

Whitehorse’s dated assignments run from 2004 to 2025. The busiest period was 2015–2019, when 8 prefixes went to 3 carriers. 7 prefixes (23%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 4 prefixes have been added, so the rate centre is still growing.

Whitehorse’s oldest prefixes, the ones the register leaves undated, belong to Northwestel and Bell Mobility: these carriers made up the landscape before competition arrived. The first dated assignment went to Bell Mobility in 2004. The most recent arrivals are Ice Wireless Inc. (2016), TELUS Mobility (2012) and Iristel Inc. (2012), a sign that new carriers are still asking for numbers in Whitehorse.

Whitehorse’s 30 prefixes provide 300,000 numbers, which corresponds to a mid-sized city or a well-established suburb that every major carrier wants a slice of.

Iristel Inc. leads with 43.3% of the prefixes, but 4 competitors have set up in Whitehorse: a market where the incumbent keeps the edge without exclusivity.

Allocation is mature: only 17.4% of the dated prefixes are less than ten years old, most having been handed out in 2015–2019, and 7 prefixes go back to the undated monopoly era. New Whitehorse numbers mostly come out of blocks that were assigned long ago.

Dialling a Whitehorse number

A single area code, 867, covers Whitehorse, and it is not overlaid with any other code on this territory: one of the few parts of Canada where seven-digit local dialling may still work. From abroad, dial +1 867 and the seven-digit number.

The numbering neighbourhood

Whitehorse shares area code 867 with at least 20 other rate centres, including Yellowknife, Iqaluit, Inuvik, Behchoko, Tuktoyaktuk, Arviat, Dawson City and Arctic Bay. The largest of them, Yellowknife, holds 35 prefixes in 867; the smallest on the list, Kimmirut, has just 3.

What a Whitehorse number tells you

A number attached to Whitehorse tells you that its prefix was issued to a carrier for this rate centre in Yukon, most often Iristel Inc.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 5 carriers present here or to a VoIP service usable anywhere. Nor does it tell you who is calling: caller ID can be spoofed, and a Yukon area code is easy to borrow to look local.

Reading a register entry for Whitehorse: code 867-322 is recorded for Iristel Inc., so every 867-322-XXXX number (10,000 possible) descends from that assignment. “Whitehorse, Yukon” there names a rate centre, not a municipality.
