Who holds these numbers

Rogers Communications Canada Inc. (Wireless) holds the largest share at 12 prefixes, 21.8% of the total, ahead of 13 other carriers. Code by code: in 604, Rogers Communications Canada Inc. (Wireless) leads with 5 of 20 prefixes ahead of 5 others; in 778, Bell Mobility leads with 6 of 20 prefixes ahead of 7 others; in 236, Iristel Inc. leads with 3 of 9 prefixes ahead of 5 others; in 672, TELUS Mobility leads with 2 of 6 prefixes ahead of 3 others. 1 carrier holds prefixes in every one of Aldergrove’s 4 area codes, while 9 appear in just one.

Wireless and wireline

32 of Aldergrove’s 55 prefixes (58.2%) are held by carriers whose registered name marks a wireless business: Rogers Communications Canada Inc. (Wireless), TELUS Mobility, Bell Mobility and Fido Solutions Inc. That makes this a mostly mobile rate centre, which is typical of recent allocations: new prefixes go overwhelmingly to cellphones. 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

Aldergrove’s dated assignments run from 1999 to 2024. The busiest period was 2005–2009, when 12 prefixes went to 6 carriers. 10 prefixes (18%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 8 prefixes have been added, so the rate centre is still growing.

Aldergrove’s oldest prefixes, the ones the register leaves undated, belong to TELUS Mobility, TELUS and Rogers Communications Canada Inc. (Wireless): 4 carriers made up the landscape before competition arrived. The first dated assignment went to Rogers Communications Canada Inc. (Wireless) in 1999. The most recent arrivals are Fibernetics Corporation (2020), IXICA Communications Inc. (2018) and Rogers Communications Canada Inc. (Cable) (2017), a sign that new carriers are still asking for numbers in Aldergrove.

Aldergrove’s 55 prefixes provide 550,000 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 Aldergrove: the leader, Rogers Communications Canada Inc. (Wireless), holds only 21.8% of the prefixes against 13 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Allocation is mature: only 17.8% of the dated prefixes are less than ten years old, most having been handed out in 2005–2009, and 10 prefixes go back to the undated monopoly era. New Aldergrove numbers mostly come out of blocks that were assigned long ago.

Dialling a Aldergrove number

Aldergrove is served by 4 overlaid area codes (604, 778, 236 and 672). A 672 number is no more “out of town” than a 604 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Aldergrove shares area codes 604, 778, 236 and 672 with at least 20 other rate centres, including Vancouver, New Westminster, Abbotsford, Victoria, Richmond, North Vancouver, Newton and Kelowna. The largest of them, Vancouver, holds 740 prefixes in 236, 604, 672 and 778; the smallest on the list, Port Moody, has just 22.

What a Aldergrove number tells you

A number attached to Aldergrove tells you that its prefix was issued to a carrier for this rate centre in British Columbia, most often Rogers Communications Canada Inc. (Wireless). It does not tell you where the handset is today: most of Aldergrove’s prefixes are mobile, and a cellphone keeps its number when its owner moves across the country. Nor does it tell you who is calling: caller ID can be spoofed, and a British Columbia area code is easy to borrow to look local.

Reading a register entry for Aldergrove: code 604-613 is recorded for Rogers Communications Canada Inc. (Wireless), so every 604-613-XXXX number (10,000 possible) descends from that assignment. “Aldergrove, British Columbia” there names a rate centre, not a municipality, and several area codes overlay it.
