Connaught’s share of its area codes

Within area code 249, Connaught accounts for only 1 of 585 prefixes (0.2%): the code is dominated by Sudbury and spread over 176 rate centres. Within area code 705, Connaught accounts for only 1 of 770 prefixes (0.1%): the code is dominated by Barrie and spread over 203 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 1 prefixes, 50.0% of the total, ahead of 1 other carrier. Code by code: Bell Canada is the only holder in 249; Northern Telephone Ltd. is the only holder in 705. No carrier holds prefixes in every one of Connaught’s 2 area codes, while 2 appear in just one.

Wireless and wireline

None of Connaught’s holders carries a mobility brand in its registered name: all 2 prefixes belong to wireline or wholesale carriers, among them Bell Canada and Northern Telephone Ltd. A call showing a Connaught number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Connaught’s dated assignments run from 2025 to 2025. The busiest period was 2025–2029, when 1 prefixes went to 1 carrier. 1 prefixes (50%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 1 prefixes have been added, so the rate centre is still growing.

Connaught’s oldest prefixes, the ones the register leaves undated, belong to Northern Telephone Ltd: this carrier made up the landscape before competition arrived. The first dated assignment went to Bell Canada in 2025. The most recent arrivals are Bell Canada (2025), a sign that new carriers are still asking for numbers in Connaught.

Connaught has just 2 prefixes (20,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

Bell Canada leads with 50.0% of the prefixes, but 1 competitors have set up in Connaught: a market where the incumbent keeps the edge without exclusivity.

Growth is recent: 100.0% of the dated prefixes were assigned in the last ten years, peaking in 2025–2029. Connaught is among the rate centres where demand for numbers is still rising quickly.

Dialling a Connaught number

Connaught is served by 2 overlaid area codes (249 and 705). A 705 number is no more “out of town” than a 249 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Connaught shares area codes 249 and 705 with at least 20 other rate centres, including Barrie, Sudbury, Peterborough, Sault Ste. Marie, North Bay, Huntsville, Collingwood and Lindsay. The largest of them, Barrie, holds 92 prefixes in 249 and 705; the smallest on the list, Kirkland Lake, has just 12.

What a Connaught number tells you

A number attached to Connaught tells you that its prefix was issued to a carrier for this rate centre in Ontario, most often Bell Canada. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 2 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 Connaught: code 249-348 is recorded for Bell Canada, so every 249-348-XXXX number (10,000 possible) descends from that assignment. “Connaught, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
