Who holds these numbers

Bell Canada holds the largest share at 1 prefixes, 11.1% of the total, ahead of 8 other carriers. Code by code: in 579, Comwave Networks leads with 1 of 8 prefixes ahead of 7 others; Bell Canada is the only holder in 450. No carrier holds prefixes in every one of Eastman’s 2 area codes, while 9 appear in just one.

Wireless and wireline

None of Eastman’s holders carries a mobility brand in its registered name: all 9 prefixes belong to wireline or wholesale carriers, among them Bell Canada, Comwave Networks, Cooptel and Distributel. A call showing a Eastman number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Eastman’s dated assignments run from 2013 to 2022. The busiest period was 2015–2019, when 3 prefixes went to 3 carriers. 1 prefixes (11%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 3 prefixes have been added, so the rate centre is still growing.

Eastman’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 Comwave Networks in 2013. The most recent arrivals are TELUS Quebec (2022), Fibernetics Corporation (2022) and IXICA Communications Inc. (2021), a sign that new carriers are still asking for numbers in Eastman.

Eastman has just 9 prefixes (90,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Eastman: the leader, Bell Canada, holds only 11.1% of the prefixes against 8 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: 37.5% of the dated prefixes go back to the last ten years, the most active period being 2015–2019. The rate centre is growing at a regular rather than explosive pace.

What a Eastman number tells you

A number attached to Eastman tells you that its prefix was issued to a carrier for this rate centre in Quebec, 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 9 carriers present here or to a VoIP service usable anywhere. Nor does it tell you who is calling: caller ID can be spoofed, and a Quebec area code is easy to borrow to look local.

Reading a register entry for Eastman: code 450-297 is recorded for Bell Canada, so every 450-297-XXXX number (10,000 possible) descends from that assignment. “Eastman, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

Every Eastman prefix

Each row is an in-service central-office code recorded for Eastman, with its original holder and year of assignment.

Had a call from a Eastman 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.

  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.

An allocation says who was issued the prefix, not who serves the number today: numbers can be ported between carriers, and caller ID can be spoofed outright.
