Perth’s share of its area codes

Within area code 613, Perth accounts for only 11 of 772 prefixes (1.4%): the code is dominated by Ottawa-Hull and spread over 132 rate centres. Within area code 343, Perth accounts for only 5 of 641 prefixes (0.8%): the code is dominated by Ottawa-Hull and spread over 116 rate centres. Within area code 753, Perth 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

Rogers Communications Canada Inc. (Wireless) holds the largest share at 4 prefixes, 22.2% of the total, ahead of 9 other carriers. Code by code: in 613, Bell Canada leads with 3 of 11 prefixes ahead of 6 others; in 343, Iristel Inc. leads with 3 of 5 prefixes ahead of 1 others; in 753, Fibernetics Corporation leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Perth’s 3 area codes, while 9 appear in just one.

Wireless and wireline

8 of Perth’s 18 prefixes (44.4%) are held by carriers whose registered name marks a wireless business: Rogers Communications Canada Inc. (Wireless), TELUS Mobility, Bell Mobility and Fido Solutions Inc. Wireline prefixes still outnumber them, carried by Bell Canada, Iristel Inc, Fibernetics Corporation and TELUS Integrated Communications. 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

Perth’s dated assignments run from 2000 to 2025. The busiest period was 2005–2009, when 4 prefixes went to 4 carriers. 2 prefixes (11%) 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.

Perth’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 Mobility in 2000. The most recent arrivals are Videotron Ltd. (2023), Fibernetics Corporation (2022) and Iristel Inc. (2016), a sign that new carriers are still asking for numbers in Perth.

Perth has only 18 prefixes, or 180,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Perth: the leader, Rogers Communications Canada Inc. (Wireless), holds only 22.2% 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: 25.0% 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 Perth number

Perth 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

Perth 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 Perth number tells you

A number attached to Perth tells you that its prefix was issued to a carrier for this rate centre in Ontario, most often Rogers Communications Canada Inc. (Wireless). 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 Perth: code 613-300 is recorded for Rogers Communications Canada Inc. (Wireless), so every 613-300-XXXX number (10,000 possible) descends from that assignment. “Perth, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
