Within area code 778, Terrace accounts for only 4 of 779 prefixes (0.5%): the code is dominated by Vancouver and spread over 159 rate centres. Within area code 236, Terrace accounts for only 2 of 730 prefixes (0.3%): the code is dominated by Vancouver and spread over 269 rate centres.

Who holds these numbers

TELUS holds the largest share at 6 prefixes, 40.0% of the total, ahead of 8 other carriers. Code by code: in 250, TELUS leads with 4 of 8 prefixes ahead of 4 others; in 778, TELUS leads with 1 of 4 prefixes ahead of 3 others; in 236, TELUS leads with 1 of 2 prefixes ahead of 1 others; TELUS Mobility is the only holder in 672. No carrier holds prefixes in every one of Terrace’s 4 area codes, while 7 appear in just one.

Wireless and wireline

5 of Terrace’s 15 prefixes (33.3%) are held by carriers whose registered name marks a wireless business: TELUS Mobility, Bell Mobility, Fido Solutions Inc and Rogers Communications Canada Inc. (Wireless). Wireline prefixes still outnumber them, carried by TELUS, Bell West Inc, CityWest Cable (North) Corp - BC and Iristel Inc. 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

Terrace’s dated assignments run from 2001 to 2024. The busiest period was 2005–2009, when 5 prefixes went to 5 carriers. 3 prefixes (20%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 2 prefixes have been added, so the rate centre is still growing.

Terrace’s oldest prefixes, the ones the register leaves undated, belong to TELUS: this carrier made up the landscape before competition arrived. The first dated assignment went to TELUS in 2001. The most recent arrivals are Iristel Inc. (2024), Navigata Communications Limited (2014) and Bell West Inc. (2011), a sign that new carriers are still asking for numbers in Terrace.

Terrace has only 15 prefixes, or 150,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

TELUS leads with 40.0% of the prefixes, but 8 competitors have set up in Terrace: a market where the incumbent keeps the edge without exclusivity.

Allocation is mature: only 16.7% of the dated prefixes are less than ten years old, most having been handed out in 2005–2009, and 3 prefixes go back to the undated monopoly era. New Terrace numbers mostly come out of blocks that were assigned long ago.

The register also shows 1 prefix assigned but not yet in service in Terrace (Fibernetics Corporation): numbers that will start showing up on call displays in the coming months.

3 undated in the register.

Dialling a Terrace number

Terrace is served by 4 overlaid area codes (250, 778, 236 and 672). A 672 number is no more “out of town” than a 250 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Terrace shares area codes 250, 778, 236 and 672 with at least 20 other rate centres, including Vancouver, Victoria, Kelowna, New Westminster, Abbotsford, Nanaimo, South Kamloops and Prince George. The largest of them, Vancouver, holds 397 prefixes in 236, 672 and 778; the smallest on the list, Campbell River, has just 21.

What a Terrace number tells you

A number attached to Terrace tells you that its prefix was issued to a carrier for this rate centre in British Columbia, most often TELUS. 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 British Columbia area code is easy to borrow to look local.

Reading a register entry for Terrace: code 250-615 is recorded for TELUS, so every 250-615-XXXX number (10,000 possible) descends from that assignment. “Terrace, British Columbia” there names a rate centre, not a municipality, and several area codes overlay it.
