Rolphton’s share of its area codes

Within area code 343, Rolphton accounts for only 1 of 641 prefixes (0.2%): the code is dominated by Ottawa-Hull and spread over 116 rate centres. Within area code 613, Rolphton 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, 50.0% of the total, ahead of 1 other carrier. Code by code: TELUS Integrated Communications is the only holder in 343; Bell Canada is the only holder in 613. No carrier holds prefixes in every one of Rolphton’s 2 area codes, while 2 appear in just one.

Wireless and wireline

None of Rolphton’s holders carries a mobility brand in its registered name: all 2 prefixes belong to wireline or wholesale carriers, among them Bell Canada and TELUS Integrated Communications. A call showing a Rolphton number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Rolphton’s dated assignments run from 2024 to 2024. The busiest period was 2020–2024, when 1 prefixes went to 1 carrier. 1 prefixes (50%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 1 prefixes have been added, so the rate centre is still growing.

Rolphton’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 2024. The most recent arrivals are TELUS Integrated Communications (2024), a sign that new carriers are still asking for numbers in Rolphton.

Rolphton has just 2 prefixes (20,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

Bell Canada leads with 50.0% of the prefixes, but 1 competitors have set up in Rolphton: a market where the incumbent keeps the edge without exclusivity.

Growth is recent: 100.0% of the dated prefixes were assigned in the last ten years, peaking in 2020–2024. Rolphton is among the rate centres where demand for numbers is still rising quickly.

Dialling a Rolphton number

Rolphton 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

Rolphton 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 Rolphton number tells you

A number attached to Rolphton 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 2 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 Rolphton: code 613-586 is recorded for Bell Canada, so every 613-586-XXXX number (10,000 possible) descends from that assignment. “Rolphton, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
