Deep River’s share of its area codes

Within area code 343, Deep River accounts for only 2 of 641 prefixes (0.3%): the code is dominated by Ottawa-Hull and spread over 116 rate centres. Within area code 613, Deep River accounts for only 1 of 772 prefixes (0.1%): the code is dominated by Ottawa-Hull and spread over 132 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 1 prefixes, 33.3% of the total, ahead of 2 other carriers. Code by code: in 343, ExaTEL Inc. leads with 1 of 2 prefixes ahead of 1 others; Bell Canada is the only holder in 613. No carrier holds prefixes in every one of Deep River’s 2 area codes, while 3 appear in just one.

Wireless and wireline

None of Deep River’s holders carries a mobility brand in its registered name: all 3 prefixes belong to wireline or wholesale carriers, among them Bell Canada, ExaTEL Inc and TELUS Integrated Communications. A call showing a Deep River number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Deep River’s dated assignments run from 2017 to 2017. The busiest period was 2015–2019, when 2 prefixes went to 2 carriers. 1 prefixes (33%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. No prefix has been added since 2020: demand for numbers in Deep River is flat.

Deep River’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 2017. The most recent arrivals are ExaTEL Inc. (2017) and TELUS Integrated Communications (2017), a sign that new carriers are still asking for numbers in Deep River.

Deep River has just 3 prefixes (30,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Deep River: the leader, Bell Canada, holds only 33.3% of the prefixes against 2 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 0.0% of the dated prefixes are less than ten years old, most having been handed out in 2015–2019, and 1 prefixes go back to the undated monopoly era. New Deep River numbers mostly come out of blocks that were assigned long ago.

Dialling a Deep River number

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

The numbering neighbourhood

Deep River shares area codes 343 and 613 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, Brighton, has just 10.

What a Deep River number tells you

A number attached to Deep River 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 3 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 Deep River: code 613-584 is recorded for Bell Canada, so every 613-584-XXXX number (10,000 possible) descends from that assignment. “Deep River, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
