Deer Lake’s share of its area codes

Within area code 709, Deer Lake accounts for only 9 of 631 prefixes (1.4%): the code is dominated by St. John's and spread over 209 rate centres. Within area code 807, Deer Lake accounts for only 1 of 293 prefixes (0.3%): the code is dominated by Thunder Bay and spread over 85 rate centres.

Who holds these numbers

Aliant Telecom (NF) holds the largest share at 2 prefixes, 20.0% of the total, ahead of 6 other carriers. Code by code: in 709, Aliant Telecom (NF) leads with 2 of 9 prefixes ahead of 5 others; Bell Canada is the only holder in 807. No carrier holds prefixes in every one of Deer Lake’s 2 area codes, while 7 appear in just one.

Wireless and wireline

3 of Deer Lake’s 10 prefixes (30.0%) are held by carriers whose registered name marks a wireless business: Bell Mobility Aliant and TELUS Mobility. Wireline prefixes still outnumber them, carried by Aliant Telecom (NF), Bragg Communications Inc, Bell Canada and Rogers Communications Canada Inc. (Cable). 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

Deer Lake’s dated assignments run from 2005 to 2026. The busiest period was 2005–2009, when 2 prefixes went to 2 carriers. 3 prefixes (30%) 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.

Deer Lake’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada, Aliant Telecom (NF) and Bell Mobility Aliant: these carriers made up the landscape before competition arrived. The first dated assignment went to Aliant Telecom (NF) in 2005. The most recent arrivals are Bragg Communications Inc. (2023), TELUS Integrated Communications (2022) and Bell Mobility Aliant (2014), a sign that new carriers are still asking for numbers in Deer Lake.

Deer Lake has only 10 prefixes, or 100,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Deer Lake: the leader, Aliant Telecom (NF), holds only 20.0% of the prefixes against 6 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Demand remains steady: 42.9% of the dated prefixes go back to the last ten years, the most active period being 2005–2009. The rate centre is growing at a regular rather than explosive pace.

Dialling a Deer Lake number

Deer Lake is served by 2 overlaid area codes (709 and 807). A 807 number is no more “out of town” than a 709 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Deer Lake shares area codes 709 and 807 with at least 20 other rate centres, including St. John's, Thunder Bay, Kenora, Corner Brook, Fort Frances, Clarenville, Carbonear and Gander. The largest of them, St. John's, holds 100 prefixes in 709; the smallest on the list, Torbay, has just 9.

What a Deer Lake number tells you

A number attached to Deer Lake tells you that its prefix was issued to a carrier for this rate centre in Newfoundland and Labrador, most often Aliant Telecom (NF). It does not tell you where the handset is today: a subscriber may have ported the number to any of the 7 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 Newfoundland and Labrador area code is easy to borrow to look local.

Reading a register entry for Deer Lake: code 709-633 is recorded for Aliant Telecom (NF), so every 709-633-XXXX number (10,000 possible) descends from that assignment. “Deer Lake, Newfoundland and Labrador” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Deer 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.

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.

4. Forward suspicious texts to 7726

   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.
