Leamington’s share of its area codes

Within area code 548, Leamington accounts for only 9 of 499 prefixes (1.8%): the code is dominated by London and spread over 170 rate centres. Within area code 519, Leamington accounts for only 7 of 779 prefixes (0.9%): the code is dominated by London and spread over 210 rate centres. Within area code 226, Leamington accounts for only 6 of 778 prefixes (0.8%): the code is dominated by London and spread over 166 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 4 prefixes, 18.2% of the total, ahead of 12 other carriers. Code by code: in 548, Iristel Inc. leads with 2 of 9 prefixes ahead of 6 others; in 519, Bell Canada leads with 4 of 7 prefixes ahead of 3 others; in 226, Iristel Inc. leads with 2 of 6 prefixes ahead of 4 others. No carrier holds prefixes in every one of Leamington’s 3 area codes, while 10 appear in just one.

Wireless and wireline

5 of Leamington’s 22 prefixes (22.7%) are held by carriers whose registered name marks a wireless business: Bell Mobility, Rogers Communications Canada Inc. (Wireless) and Fido Solutions Inc. Wireline prefixes still outnumber them, carried by Bell Canada, Iristel Inc, Fibernetics Corporation and Distributel. This is a sort by name, not a licence lookup, and a mobile prefix may have been ported to another network since.

How the allocation was built up

Leamington’s dated assignments run from 2000 to 2025. The busiest period was 2020–2024, when 8 prefixes went to 6 carriers. 3 prefixes (14%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 9 prefixes have been added, so the rate centre is still growing.

Leamington’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 Gosfield North Communication Co-operative Ltd. (2023), IXICA Communications Inc. (2021) and Fibernetics Corporation (2020), a sign that new carriers are still asking for numbers in Leamington.

Leamington has only 22 prefixes, or 220,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Leamington: the leader, Bell Canada, holds only 18.2% of the prefixes against 12 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: 47.4% 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.

Dialling a Leamington number

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

The numbering neighbourhood

Leamington shares area codes 548, 519 and 226 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, St. Thomas, has just 15.

What a Leamington number tells you

A number attached to Leamington 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 13 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 Leamington: code 519-322 is recorded for Bell Canada, so every 519-322-XXXX number (10,000 possible) descends from that assignment. “Leamington, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
