Who holds these numbers

Bell Canada holds the largest share at 3 prefixes, 12.5% of the total, ahead of 15 other carriers. Code by code: in 289, TELUS Mobility leads with 2 of 11 prefixes ahead of 9 others; in 365, Distributel leads with 1 of 4 prefixes ahead of 3 others; in 905, Bell Canada leads with 3 of 4 prefixes ahead of 1 others; in 902, TELUS Mobility leads with 1 of 3 prefixes ahead of 2 others; in 742, Rogers Communications Canada Inc. (Cable) leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Georgetown’s 5 area codes, while 11 appear in just one.

Wireless and wireline

6 of Georgetown’s 24 prefixes (25.0%) are held by carriers whose registered name marks a wireless business: TELUS Mobility, Rogers Communications Canada Inc. (Wireless) and Fido Solutions Inc. Wireline prefixes still outnumber them, carried by Bell Canada, Distributel, Fibernetics Corporation and Rogers Communications Canada Inc. (Cable). 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

Georgetown’s dated assignments run from 2005 to 2025. The busiest period was 2005–2009, when 7 prefixes went to 7 carriers. 5 prefixes (21%) 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.

Georgetown’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada, Aliant Telecom (PEI) and Rogers Communications Canada Inc. (Wireless): these carriers made up the landscape before competition arrived. The first dated assignment went to Bragg Communications Inc. in 2005. The most recent arrivals are Cogeco Connexion Inc. (2025), TekSavvy Solutions Inc (2021) and IXICA Communications Inc. (2017), a sign that new carriers are still asking for numbers in Georgetown.

Georgetown has only 24 prefixes, or 240,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Georgetown: the leader, Bell Canada, holds only 12.5% of the prefixes against 15 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: 21.1% 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 Georgetown number

Georgetown is served by 5 overlaid area codes (289, 365, 905, 902 and 742). A 742 number is no more “out of town” than a 289 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Georgetown shares area codes 289, 365, 905, 902 and 742 with at least 20 other rate centres, including Hamilton, Halifax, Brampton, Oshawa, St. Catharines-Thorold, Oakville, Markham and Ajax-Pickering. The largest of them, Hamilton, holds 221 prefixes in 289, 365, 742 and 905; the smallest on the list, Niagara Falls, has just 36.

What a Georgetown number tells you

A number attached to Georgetown 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 16 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 Georgetown: code 905-702 is recorded for Bell Canada, so every 905-702-XXXX number (10,000 possible) descends from that assignment. “Georgetown, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
