Carleton Place’s share of its area codes

Within area code 613, Carleton Place accounts for only 13 of 772 prefixes (1.7%): the code is dominated by Ottawa-Hull and spread over 132 rate centres. Within area code 343, Carleton Place accounts for only 9 of 641 prefixes (1.4%): the code is dominated by Ottawa-Hull and spread over 116 rate centres. Within area code 753, Carleton Place accounts for only 1 of 103 prefixes (1.0%): the code is dominated by Ottawa-Hull and spread over 62 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 4 prefixes, 17.4% of the total, ahead of 11 other carriers. Code by code: in 613, Bell Canada leads with 4 of 13 prefixes ahead of 6 others; in 343, Iristel Inc. leads with 4 of 9 prefixes ahead of 5 others; IXICA Communications Inc. is the only holder in 753. No carrier holds prefixes in every one of Carleton Place’s 3 area codes, while 10 appear in just one.

Wireless and wireline

5 of Carleton Place’s 23 prefixes (21.7%) are held by carriers whose registered name marks a wireless business: Bell Mobility, Rogers Communications Canada Inc. (Wireless) and Fido Solutions Inc. Wireline prefixes still outnumber them, carried by Bell Canada, Iristel Inc, Fibernetics Corporation and ISP Telecom Inc. 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

Carleton Place’s dated assignments run from 2002 to 2024. The busiest period was 2015–2019, when 8 prefixes went to 6 carriers. 4 prefixes (17%) 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.

Carleton Place’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 Rogers Communications Canada Inc. (Wireless) in 2002. The most recent arrivals are IXICA Communications Inc. (2018), Distributel (2016) and Iristel Inc. (2016), a sign that new carriers are still asking for numbers in Carleton Place.

Carleton Place has only 23 prefixes, or 230,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Carleton Place: the leader, Bell Canada, holds only 17.4% of the prefixes against 11 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Allocation is mature: only 10.5% of the dated prefixes are less than ten years old, most having been handed out in 2015–2019, and 4 prefixes go back to the undated monopoly era. New Carleton Place numbers mostly come out of blocks that were assigned long ago.

Dialling a Carleton Place number

Carleton Place is served by 3 overlaid area codes (613, 343 and 753). A 753 number is no more “out of town” than a 613 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Carleton Place shares area codes 613, 343 and 753 with at least 20 other rate centres, including Ottawa-Hull, Kingston, Belleville, Cornwall, Kanata-Stittsville, Brockville, Smiths Falls and Bancroft. The largest of them, Ottawa-Hull, holds 441 prefixes in 343, 613 and 753; the smallest on the list, Merrickville, has just 11.

What a Carleton Place number tells you

A number attached to Carleton Place 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 12 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 Carleton Place: code 613-250 is recorded for Bell Canada, so every 613-250-XXXX number (10,000 possible) descends from that assignment. “Carleton Place, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
