Pembroke’s share of its area codes

Within area code 613, Pembroke accounts for only 16 of 772 prefixes (2.1%): the code is dominated by Ottawa-Hull and spread over 132 rate centres. Within area code 343, Pembroke accounts for only 6 of 641 prefixes (0.9%): the code is dominated by Ottawa-Hull and spread over 116 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 6 prefixes, 27.3% of the total, ahead of 9 other carriers. Code by code: in 613, Bell Canada leads with 5 of 16 prefixes ahead of 7 others; in 343, Videotron Ltd. leads with 2 of 6 prefixes ahead of 4 others. 3 carriers hold prefixes in every one of Pembroke’s 2 area codes, while 7 appear in just one.

Wireless and wireline

10 of Pembroke’s 22 prefixes (45.5%) are held by carriers whose registered name marks a wireless business: Bell Mobility, Rogers Communications Canada Inc. (Wireless), TELUS Mobility and Fido Solutions Inc. Wireline prefixes still outnumber them, carried by Bell Canada, Videotron Ltd, Cogeco Connexion Inc and ExaTEL 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

Pembroke’s dated assignments run from 2000 to 2025. The busiest period was 2005–2009, when 7 prefixes went to 6 carriers. 4 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 2 prefixes have been added, so the rate centre is still growing.

Pembroke’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 Cogeco Connexion Inc. (2025), Videotron Ltd. (2018) and TELUS Integrated Communications (2009), a sign that new carriers are still asking for numbers in Pembroke.

Pembroke has only 22 prefixes, or 220,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Pembroke: the leader, Bell Canada, holds only 27.3% 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.

Allocation is mature: only 11.1% of the dated prefixes are less than ten years old, most having been handed out in 2005–2009, and 4 prefixes go back to the undated monopoly era. New Pembroke numbers mostly come out of blocks that were assigned long ago.

Dialling a Pembroke number

Pembroke is served by 2 overlaid area codes (613 and 343). A 343 number is no more “out of town” than a 613 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Pembroke shares area codes 613 and 343 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 425 prefixes in 343 and 613; the smallest on the list, Cumberland, has just 10.

What a Pembroke number tells you

A number attached to Pembroke 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 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 Pembroke: code 613-633 is recorded for Bell Canada, so every 613-633-XXXX number (10,000 possible) descends from that assignment. “Pembroke, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
