Miramichi’s share of its area codes

Within area code 506, Miramichi accounts for only 28 of 677 prefixes (4.1%): the code is dominated by Moncton and spread over 88 rate centres. Within area code 428, Miramichi accounts for only 2 of 21 prefixes (9.5%): the code is dominated by Bathurst and spread over 15 rate centres.

Who holds these numbers

Aliant Telecom(NB) holds the largest share at 10 prefixes, 33.3% of the total, ahead of 11 other carriers. Code by code: in 506, Aliant Telecom(NB) leads with 10 of 28 prefixes ahead of 11 others; in 428, Iristel Inc. leads with 1 of 2 prefixes ahead of 1 others. 2 carriers hold prefixes in every one of Miramichi’s 2 area codes, while 10 appear in just one.

Wireless and wireline

7 of Miramichi’s 30 prefixes (23.3%) are held by carriers whose registered name marks a wireless business: TELUS Mobility, Bell Mobility Aliant, Fido Solutions Inc and Rogers Communications Canada Inc. (Wireless). Wireline prefixes still outnumber them, carried by Aliant Telecom(NB), Iristel Inc, Bragg Communications Inc and TELUS Integrated Communications. 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

Miramichi’s dated assignments run from 2001 to 2025. The busiest period was 2010–2014, when 6 prefixes went to 5 carriers. 7 prefixes (23%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 7 prefixes have been added, so the rate centre is still growing.

Miramichi’s oldest prefixes, the ones the register leaves undated, belong to Aliant Telecom(NB): this carrier made up the landscape before competition arrived. The first dated assignment went to Bell Mobility Aliant in 2001. The most recent arrivals are Distributel (2022), Bragg Communications Inc. (2022) and Rogers Communications Canada Inc. (2019), a sign that new carriers are still asking for numbers in Miramichi.

Miramichi’s 30 prefixes provide 300,000 numbers, which corresponds to a mid-sized city or a well-established suburb that every major carrier wants a slice of.

No single carrier dominates Miramichi: the leader, Aliant Telecom(NB), holds only 33.3% of the prefixes against 11 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: 30.4% of the dated prefixes go back to the last ten years, the most active period being 2010–2014. The rate centre is growing at a regular rather than explosive pace.

Dialling a Miramichi number

Miramichi is served by 2 overlaid area codes (506 and 428). A 428 number is no more “out of town” than a 506 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Miramichi shares area codes 506 and 428 with at least 20 other rate centres, including Moncton, Saint John, Fredericton, Bathurst, Edmundston, Campbellton, Woodstock and Tracadie. The largest of them, Moncton, holds 81 prefixes in 428 and 506; the smallest on the list, Sackville, has just 10.

What a Miramichi number tells you

A number attached to Miramichi tells you that its prefix was issued to a carrier for this rate centre in New Brunswick, most often Aliant Telecom(NB). It does not tell you where the handset is today: a subscriber may have ported the number to any of the 12 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 New Brunswick area code is easy to borrow to look local.

Reading a register entry for Miramichi: code 506-417 is recorded for Aliant Telecom(NB), so every 506-417-XXXX number (10,000 possible) descends from that assignment. “Miramichi, New Brunswick” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Miramichi 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.

   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.
