Perth-Andover’s share of its area codes

Within area code 506, Perth-Andover accounts for only 5 of 677 prefixes (0.7%): the code is dominated by Moncton and spread over 88 rate centres. Within area code 428, Perth-Andover accounts for only 1 of 21 prefixes (4.8%): the code is dominated by Bathurst and spread over 15 rate centres.

Who holds these numbers

Bell Mobility Aliant holds the largest share at 2 prefixes, 33.3% of the total, ahead of 3 other carriers. Code by code: in 506, Bell Mobility Aliant leads with 2 of 5 prefixes ahead of 3 others; Iristel Inc. is the only holder in 428. 1 carrier holds prefixes in every one of Perth-Andover’s 2 area codes, while 3 appear in just one.

Wireless and wireline

2 of Perth-Andover’s 6 prefixes (33.3%) are held by carriers whose registered name marks a wireless business: Bell Mobility Aliant. Wireline prefixes still outnumber them, carried by Iristel Inc, Aliant Telecom(NB) 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

Perth-Andover’s dated assignments run from 2005 to 2023. The busiest period was 2005–2009, when 2 prefixes went to 1 carrier. 1 prefixes (17%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 1 prefixes have been added, so the rate centre is still growing.

Perth-Andover’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 2005. The most recent arrivals are Iristel Inc. (2016), Rogers Communications Canada Inc. (Cable) (2010) and Bell Mobility Aliant (2005), a sign that new carriers are still asking for numbers in Perth-Andover.

Perth-Andover has just 6 prefixes (60,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Perth-Andover: the leader, Bell Mobility Aliant, holds only 33.3% of the prefixes against 3 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: 20.0% 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 Perth-Andover number

Perth-Andover 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

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

What a Perth-Andover number tells you

A number attached to Perth-Andover tells you that its prefix was issued to a carrier for this rate centre in New Brunswick, most often Bell Mobility Aliant. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 4 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 Perth-Andover: code 506-274 is recorded for Bell Mobility Aliant, so every 506-274-XXXX number (10,000 possible) descends from that assignment. “Perth-Andover, New Brunswick” there names a rate centre, not a municipality, and several area codes overlay it.
