Acton’s share of its area codes

Within area code 226, Acton accounts for only 6 of 778 prefixes (0.8%): the code is dominated by London and spread over 166 rate centres. Within area code 548, Acton accounts for only 3 of 499 prefixes (0.6%): the code is dominated by London and spread over 170 rate centres. Within area code 519, Acton accounts for only 2 of 779 prefixes (0.3%): the code is dominated by London and spread over 210 rate centres.

Who holds these numbers

Fibernetics Corporation holds the largest share at 2 prefixes, 18.2% of the total, ahead of 9 other carriers. Code by code: in 226, Fibernetics Corporation leads with 1 of 6 prefixes ahead of 5 others; in 548, Fibernetics Corporation leads with 1 of 3 prefixes ahead of 2 others; in 519, Bell Canada leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Acton’s 3 area codes, while 9 appear in just one.

Wireless and wireline

None of Acton’s holders carries a mobility brand in its registered name: all 11 prefixes belong to wireline or wholesale carriers, among them Fibernetics Corporation, Bell Canada, Cogeco Connexion Inc and Comwave Networks. A call showing a Acton number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Acton’s dated assignments run from 2006 to 2025. The busiest period was 2005–2009, when 3 prefixes went to 3 carriers. 1 prefixes (9%) 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.

Acton’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 2006. The most recent arrivals are Cogeco Connexion Inc. (2025), ISP Telecom Inc. (2021) and IXICA Communications Inc. (2020), a sign that new carriers are still asking for numbers in Acton.

Acton has only 11 prefixes, or 110,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Acton: the leader, Fibernetics Corporation, holds only 18.2% 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: 40.0% 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 Acton number

Acton is served by 3 overlaid area codes (226, 548 and 519). A 519 number is no more “out of town” than a 226 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Acton shares area codes 226, 548 and 519 with at least 20 other rate centres, including London, Kitchener-Waterloo, Windsor, Guelph, Brantford, Sarnia, Chatham and Hespeler. The largest of them, London, holds 214 prefixes in 226, 519 and 548; the smallest on the list, Essex, has just 16.

What a Acton number tells you

A number attached to Acton tells you that its prefix was issued to a carrier for this rate centre in Ontario, most often Fibernetics Corporation. 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 Acton: code 226-828 is recorded for Fibernetics Corporation, so every 226-828-XXXX number (10,000 possible) descends from that assignment. “Acton, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
