Moncton’s share of its area codes

Within area code 506, Moncton takes 79 of 677 prefixes (11.7%), a substantial slice of a code shared by 88 rate centres, the largest of them Moncton. Within area code 428, Moncton 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 29 prefixes, 35.8% of the total, ahead of 10 other carriers. Code by code: in 506, Aliant Telecom(NB) leads with 29 of 79 prefixes ahead of 10 others; in 428, Rogers Communications Canada Inc. (Wireless) leads with 1 of 2 prefixes ahead of 1 others. 2 carriers hold prefixes in every one of Moncton’s 2 area codes, while 9 appear in just one.

Wireless and wireline

30 of Moncton’s 81 prefixes (37.0%) are held by carriers whose registered name marks a wireless business: Bell Mobility Aliant, Rogers Communications Canada Inc. (Wireless), TELUS Mobility and Fido Solutions Inc. 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

Moncton’s dated assignments run from 2000 to 2025. The busiest period was 2010–2014, when 17 prefixes went to 9 carriers. 29 prefixes (36%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 13 prefixes have been added, so the rate centre is still growing.

Moncton’s oldest prefixes, the ones the register leaves undated, belong to Aliant Telecom(NB), Bell Mobility Aliant and Rogers Communications Canada Inc. (Wireless): these carriers made up the landscape before competition arrived. The first dated assignment went to Bell Mobility Aliant in 2000. The most recent arrivals are Distributel (2016), Bragg Communications Inc. (2014) and Comwave Networks (2014), a sign that new carriers are still asking for numbers in Moncton.

Moncton’s 81 prefixes provide 810,000 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 Moncton: the leader, Aliant Telecom(NB), holds only 35.8% of the prefixes against 10 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: 25.0% 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 Moncton number

Moncton 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

Moncton shares area codes 506 and 428 with at least 20 other rate centres, including Saint John, Fredericton, Miramichi, Bathurst, Edmundston, Campbellton, Woodstock and Tracadie. The largest of them, Saint John, holds 78 prefixes in 428 and 506; the smallest on the list, Sackville, has just 10.

What a Moncton number tells you

A number attached to Moncton 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 11 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 Moncton: code 506-382 is recorded for Aliant Telecom(NB), so every 506-382-XXXX number (10,000 possible) descends from that assignment. “Moncton, New Brunswick” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Moncton 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.
