Amherstburg’s share of its area codes

Within area code 548, Amherstburg accounts for only 4 of 499 prefixes (0.8%): the code is dominated by London and spread over 170 rate centres. Within area code 226, Amherstburg accounts for only 3 of 778 prefixes (0.4%): the code is dominated by London and spread over 166 rate centres. Within area code 519, Amherstburg accounts for only 3 of 779 prefixes (0.4%): the code is dominated by London and spread over 210 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 2 prefixes, 20.0% of the total, ahead of 7 other carriers. Code by code: in 548, Fibernetics Corporation leads with 2 of 4 prefixes ahead of 2 others; in 226, InnSysVoice Corp leads with 1 of 3 prefixes ahead of 2 others; in 519, Bell Canada leads with 2 of 3 prefixes ahead of 1 others. No carrier holds prefixes in every one of Amherstburg’s 3 area codes, while 8 appear in just one.

Wireless and wireline

None of Amherstburg’s holders carries a mobility brand in its registered name: all 10 prefixes belong to wireline or wholesale carriers, among them Bell Canada, Fibernetics Corporation, Distributel and ISP Telecom Inc. A call showing a Amherstburg number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Amherstburg’s dated assignments run from 2000 to 2023. The busiest period was 2020–2024, when 4 prefixes went to 3 carriers. 1 prefixes (10%) 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.

Amherstburg’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 Bell Canada in 2000. The most recent arrivals are IXICA Communications Inc. (2021), Fibernetics Corporation (2020) and TekSavvy Solutions Inc (2020), a sign that new carriers are still asking for numbers in Amherstburg.

Amherstburg has only 10 prefixes, or 100,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Amherstburg: the leader, Bell Canada, holds only 20.0% of the prefixes against 7 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: 44.4% of the dated prefixes go back to the last ten years, the most active period being 2020–2024. The rate centre is growing at a regular rather than explosive pace.

The register also shows 1 prefix assigned but not yet in service in Amherstburg (Managed Network Systems Inc): numbers that will start showing up on call displays in the coming months.

Dialling a Amherstburg number

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

The numbering neighbourhood

Amherstburg shares area codes 548, 226 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 Amherstburg number tells you

A number attached to Amherstburg 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 8 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 Amherstburg: code 519-730 is recorded for Bell Canada, so every 519-730-XXXX number (10,000 possible) descends from that assignment. “Amherstburg, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Amherstburg number?

No clear pattern in reports on these numbers yet. If a call worried you:

1. Call back on a number you trust

   If a caller says they are your bank, the Canada Revenue Agency, a courier or your phone company, hang up and call the organization on the number from its website or your statement, never the number that called you. Caller ID can be faked.

2. Report the fraud

   Report the call or text to the Canadian Anti-Fraud Centre online or at 1-888-495-8501. If you lost money or gave out personal details, tell your bank first, then your local police.

   Report to the Canadian Anti-Fraud Centre ↗

3. Register on the National Do Not Call List

   Registering a landline or mobile on the National DNCL is free. Registered charities, political parties, newspapers and companies you already do business with may still call.

4. Forward suspicious texts to 7726

   Forward a scam or spam text to 7726 (SPAM on the keypad). It's free, and your carrier uses it to block the sender. Don't tap links or reply.
