Bailieboro’s share of its area codes

Within area code 249, Bailieboro accounts for only 2 of 585 prefixes (0.3%): the code is dominated by Sudbury and spread over 176 rate centres. Within area code 705, Bailieboro accounts for only 2 of 770 prefixes (0.3%): the code is dominated by Barrie and spread over 203 rate centres. Within area code 683, Bailieboro 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

Bell Canada holds the largest share at 1 prefixes, 20.0% of the total, ahead of 4 other carriers. Code by code: in 249, Fibernetics Corporation leads with 1 of 2 prefixes ahead of 1 others; in 705, Bell Canada leads with 1 of 2 prefixes ahead of 1 others; ISP Telecom Inc. is the only holder in 683. No carrier holds prefixes in every one of Bailieboro’s 3 area codes, while 5 appear in just one.

Wireless and wireline

None of Bailieboro’s holders carries a mobility brand in its registered name: all 5 prefixes belong to wireline or wholesale carriers, among them Bell Canada, Fibernetics Corporation, ISP Telecom Inc and InnSysVoice Corp. A call showing a Bailieboro number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Bailieboro’s dated assignments run from 2008 to 2023. The busiest period was 2020–2024, when 2 prefixes went to 2 carriers. 1 prefixes (20%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 2 prefixes have been added, so the rate centre is still growing.

Bailieboro’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 Nexicom Telecommunications Inc in 2008. The most recent arrivals are ISP Telecom Inc. (2023), Fibernetics Corporation (2020) and InnSysVoice Corp (2018), a sign that new carriers are still asking for numbers in Bailieboro.

Bailieboro has just 5 prefixes (50,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Bailieboro: the leader, Bell Canada, holds only 20.0% of the prefixes against 4 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. Bailieboro is among the rate centres where demand for numbers is still rising quickly.

Dialling a Bailieboro number

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

The numbering neighbourhood

Bailieboro shares area codes 249, 705 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, Kapuskasing, has just 12.

What a Bailieboro number tells you

A number attached to Bailieboro 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 5 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 Bailieboro: code 705-939 is recorded for Bell Canada, so every 705-939-XXXX number (10,000 possible) descends from that assignment. “Bailieboro, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
