Arnprior’s share of its area codes

Within area code 343, Arnprior accounts for only 6 of 641 prefixes (0.9%): the code is dominated by Ottawa-Hull and spread over 116 rate centres. Within area code 613, Arnprior accounts for only 3 of 772 prefixes (0.4%): the code is dominated by Ottawa-Hull and spread over 132 rate centres. Within area code 753, Arnprior accounts for only 2 of 103 prefixes (1.9%): the code is dominated by Ottawa-Hull and spread over 62 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 2 prefixes, 18.2% of the total, ahead of 8 other carriers. Code by code: in 343, Fibernetics Corporation leads with 2 of 6 prefixes ahead of 4 others; in 613, Bell Canada leads with 2 of 3 prefixes ahead of 1 others; in 753, IXICA Communications Inc. leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Arnprior’s 3 area codes, while 9 appear in just one.

Wireless and wireline

None of Arnprior’s holders carries a mobility brand in its registered name: all 11 prefixes belong to wireline or wholesale carriers, among them Bell Canada, Fibernetics Corporation, Cogeco Connexion Inc and Distributel. A call showing a Arnprior number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Arnprior’s dated assignments run from 2007 to 2025. The busiest period was 2020–2024, when 5 prefixes went to 4 carriers. 2 prefixes (18%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 6 prefixes have been added, so the rate centre is still growing.

Arnprior’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 TELUS Integrated Communications in 2007. The most recent arrivals are Cogeco Connexion Inc. (2025), Rogers Communications Canada Inc. (Cable) (2022) and IXICA Communications Inc. (2022), a sign that new carriers are still asking for numbers in Arnprior.

Arnprior has only 11 prefixes, or 110,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Arnprior: the leader, Bell Canada, holds only 18.2% of the prefixes against 8 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: 66.7% of the dated prefixes were assigned in the last ten years, peaking in 2020–2024. Arnprior is among the rate centres where demand for numbers is still rising quickly.

Dialling a Arnprior number

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

The numbering neighbourhood

Arnprior shares area codes 343, 613 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 Arnprior number tells you

A number attached to Arnprior 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 9 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 Arnprior: code 613-622 is recorded for Bell Canada, so every 613-622-XXXX number (10,000 possible) descends from that assignment. “Arnprior, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
