Timmins’s share of its area codes

Within area code 705, Timmins accounts for only 20 of 770 prefixes (2.6%): the code is dominated by Barrie and spread over 203 rate centres. Within area code 249, Timmins accounts for only 6 of 585 prefixes (1.0%): the code is dominated by Sudbury and spread over 176 rate centres. Within area code 683, Timmins accounts for only 1 of 80 prefixes (1.3%): the code is dominated by Lindsay and spread over 57 rate centres.

Who holds these numbers

Northern Telephone Ltd. holds the largest share at 8 prefixes, 29.6% of the total, ahead of 9 other carriers. Code by code: in 705, Northern Telephone Ltd. leads with 7 of 20 prefixes ahead of 8 others; in 249, Bragg Communications Inc. leads with 3 of 6 prefixes ahead of 3 others; Bell Mobility is the only holder in 683. No carrier holds prefixes in every one of Timmins’s 3 area codes, while 6 appear in just one.

Wireless and wireline

10 of Timmins’s 27 prefixes (37.0%) are held by carriers whose registered name marks a wireless business: TELUS Mobility, Bell Mobility, Rogers Communications Canada Inc. (Wireless) and Fido Solutions Inc. Wireline prefixes still outnumber them, carried by Northern Telephone Ltd, Bragg Communications Inc, TELUS Integrated Communications and Bell Canada. 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

Timmins’s dated assignments run from 2002 to 2025. The busiest period was 2005–2009, when 5 prefixes went to 5 carriers. 7 prefixes (26%) 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.

Timmins’s oldest prefixes, the ones the register leaves undated, belong to Northern Telephone Ltd and TELUS Integrated Communications: these carriers made up the landscape before competition arrived. The first dated assignment went to Rogers Communications Canada Inc. (Wireless) in 2002. The most recent arrivals are Bell Canada (2025), TELUS Integrated Communications (2023) and NorthernTel Limited Partnership (2013), a sign that new carriers are still asking for numbers in Timmins.

Timmins has only 27 prefixes, or 270,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Timmins: the leader, Northern Telephone Ltd., holds only 29.6% of the prefixes against 9 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: 20.0% 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 Timmins number

Timmins is served by 3 overlaid area codes (705, 249 and 683). A 683 number is no more “out of town” than a 705 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Timmins shares area codes 705, 249 and 683 with at least 20 other rate centres, including Barrie, Sudbury, Peterborough, Sault Ste. Marie, North Bay, Huntsville, Lindsay and Collingwood. The largest of them, Barrie, holds 95 prefixes in 249, 683 and 705; the smallest on the list, Kirkland Lake, has just 12.

What a Timmins number tells you

A number attached to Timmins tells you that its prefix was issued to a carrier for this rate centre in Ontario, most often Northern Telephone Ltd.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 10 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 Timmins: code 705-225 is recorded for Northern Telephone Ltd., so every 705-225-XXXX number (10,000 possible) descends from that assignment. “Timmins, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
