Marsh Lake’s share of its area code

Within area code 867, Marsh Lake accounts for only 1 of 258 prefixes (0.4%): the code is dominated by Yellowknife and spread over 75 rate centres.

Who holds these numbers

Northwestel holds every prefix here. Code by code: Northwestel is the only holder in 867.

Wireless and wireline

None of Marsh Lake’s holders carries a mobility brand in its registered name: all 1 prefixes belong to wireline or wholesale carriers, among them Northwestel. A call showing a Marsh Lake number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

The register dates none of Marsh Lake’s assignments: all 1 prefixes predate CNAC’s record-keeping, the signature of an old, settled network where nothing has been added in decades.

Northwestel is the only carrier ever recorded for Marsh Lake: no competitor has obtained a prefix here. A single-carrier rate centre is typical of small communities where only the incumbent ever built a network.

Marsh Lake has just 1 prefix (10,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

The local market is an allocation monopoly: Northwestel holds every prefix, and no competitor has ever requested a code for Marsh Lake.

Dialling a Marsh Lake number

A single area code, 867, covers Marsh Lake, 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

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

What a Marsh Lake number tells you

A number attached to Marsh Lake tells you that its prefix was issued to a carrier for this rate centre in Yukon, most often Northwestel. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 1 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 Marsh Lake: code 867-660 is recorded for Northwestel, so every 867-660-XXXX number (10,000 possible) descends from that assignment. “Marsh Lake, Yukon” there names a rate centre, not a municipality.

Had a call from a Marsh Lake 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.
