Enterprise’s share of its area codes

Within area code 343, Enterprise accounts for only 3 of 641 prefixes (0.5%): the code is dominated by Ottawa-Hull and spread over 116 rate centres. Within area code 613, Enterprise accounts for only 1 of 772 prefixes (0.1%): the code is dominated by Ottawa-Hull and spread over 132 rate centres. Within area code 867, Enterprise accounts for only 1 of 258 prefixes (0.4%): the code is dominated by Yellowknife and spread over 75 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 1 prefixes, 20.0% of the total, ahead of 4 other carriers. Code by code: in 343, Distributel leads with 1 of 3 prefixes ahead of 2 others; Bell Canada is the only holder in 613; Northwestel is the only holder in 867. No carrier holds prefixes in every one of Enterprise’s 3 area codes, while 5 appear in just one.

Wireless and wireline

None of Enterprise’s holders carries a mobility brand in its registered name: all 5 prefixes belong to wireline or wholesale carriers, among them Bell Canada, Distributel, Fibernetics Corporation and ISP Telecom Inc. A call showing a Enterprise number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Enterprise’s dated assignments run from 2018 to 2022. The busiest period was 2020–2024, when 2 prefixes went to 2 carriers. 2 prefixes (40%) 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.

Enterprise’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada and Northwestel: these carriers made up the landscape before competition arrived. The first dated assignment went to Distributel in 2018. The most recent arrivals are Fibernetics Corporation (2022), ISP Telecom Inc. (2021) and Distributel (2018), a sign that new carriers are still asking for numbers in Enterprise.

Enterprise has just 5 prefixes (50,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Enterprise: the leader, Bell Canada, holds only 20.0% of the prefixes against 4 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. Enterprise is among the rate centres where demand for numbers is still rising quickly.

Dialling a Enterprise number

Enterprise is served by 3 overlaid area codes (343, 613 and 867). A 867 number is no more “out of town” than a 343 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Enterprise shares area codes 343, 613 and 867 with at least 20 other rate centres, including Ottawa-Hull, Kingston, Belleville, Cornwall, Kanata-Stittsville, Yellowknife, Brockville and Whitehorse. The largest of them, Ottawa-Hull, holds 425 prefixes in 343 and 613; the smallest on the list, Hawkesbury, has just 12.

What a Enterprise number tells you

A number attached to Enterprise 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 5 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 Enterprise: code 613-358 is recorded for Bell Canada, so every 613-358-XXXX number (10,000 possible) descends from that assignment. “Enterprise, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.

Every Enterprise prefix

Each row is an in-service central-office code recorded for Enterprise, with its original holder and year of assignment.
