Sioux Lookout’s share of its area code

Within area code 807, Sioux Lookout accounts for only 7 of 293 prefixes (2.4%): the code is dominated by Thunder Bay and spread over 85 rate centres.

Who holds these numbers

Keewaytinook Okimakanak holds the largest share at 2 prefixes, 28.6% of the total, ahead of 5 other carriers. Code by code: in 807, Keewaytinook Okimakanak leads with 2 of 7 prefixes ahead of 5 others.

Wireless and wireline

2 of Sioux Lookout’s 7 prefixes (28.6%) are held by carriers whose registered name marks a wireless business: Bell Mobility and Rogers Communications Canada Inc. (Wireless). Wireline prefixes still outnumber them, carried by Keewaytinook Okimakanak, Bell Canada, Distributel and TBayTel. 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

Sioux Lookout’s dated assignments run from 2004 to 2023. The busiest period was 2020–2024, when 3 prefixes went to 3 carriers. 1 prefixes (14%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 3 prefixes have been added, so the rate centre is still growing.

Sioux Lookout’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada: this carrier made up the landscape before competition arrived. The first dated assignment went to Rogers Communications Canada Inc. (Wireless) in 2004. The most recent arrivals are TBayTel (2023), Distributel (2022) and Bell Mobility (2014), a sign that new carriers are still asking for numbers in Sioux Lookout.

Sioux Lookout has just 7 prefixes (70,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Sioux Lookout: the leader, Keewaytinook Okimakanak, holds only 28.6% of the prefixes against 5 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Growth is recent: 50.0% of the dated prefixes were assigned in the last ten years, peaking in 2020–2024. Sioux Lookout is among the rate centres where demand for numbers is still rising quickly.

Dialling a Sioux Lookout number

A single area code, 807, covers Sioux Lookout, 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 +1 807 and the seven-digit number.

The numbering neighbourhood

Sioux Lookout shares area code 807 with at least 20 other rate centres, including Thunder Bay, Kenora, Fort Frances, Dryden, Marathon, Nipigon, Atikokan and Geraldton. The largest of them, Thunder Bay, holds 67 prefixes in 807; the smallest on the list, Jaffray-Melick, has just 2.

What a Sioux Lookout number tells you

A number attached to Sioux Lookout tells you that its prefix was issued to a carrier for this rate centre in Ontario, most often Keewaytinook Okimakanak. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 6 carriers present here or to a VoIP service usable anywhere. Nor does it tell you who is calling: caller ID can be spoofed, and an Ontario area code is easy to borrow to look local.

Reading a register entry for Sioux Lookout: code 807-214 is recorded for Keewaytinook Okimakanak, so every 807-214-XXXX number (10,000 possible) descends from that assignment. “Sioux Lookout, Ontario” there names a rate centre, not a municipality.

Had a call from a Sioux Lookout number?

No clear pattern in reports on these numbers yet. If a call worried you:

1. Call back on a number you trust

   If a caller says they are your bank, the Canada Revenue Agency, a courier or your phone company, hang up and call the organization on the number from its website or your statement, never the number that called you. Caller ID can be faked.

2. Report the fraud

   Report the call or text to the Canadian Anti-Fraud Centre online or at 1-888-495-8501. If you lost money or gave out personal details, tell your bank first, then your local police.

3. Register on the National Do Not Call List

   Registering a landline or mobile on the National DNCL is free. Registered charities, political parties, newspapers and companies you already do business with may still call.

   Forward a scam or spam text to 7726 (SPAM on the keypad). It's free, and your carrier uses it to block the sender. Don't tap links or reply.
