Flatrock’s share of its area codes

Within area code 236, Flatrock accounts for only 1 of 730 prefixes (0.1%): the code is dominated by Vancouver and spread over 269 rate centres. Within area code 250, Flatrock accounts for only 1 of 781 prefixes (0.1%): the code is dominated by Victoria and spread over 268 rate centres.

Who holds these numbers

Distributel holds the largest share at 1 prefixes, 50.0% of the total, ahead of 1 other carrier. Code by code: Distributel is the only holder in 236; TELUS is the only holder in 250. No carrier holds prefixes in every one of Flatrock’s 2 area codes, while 2 appear in just one.

Wireless and wireline

None of Flatrock’s holders carries a mobility brand in its registered name: all 2 prefixes belong to wireline or wholesale carriers, among them Distributel and TELUS. A call showing a Flatrock number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Flatrock’s dated assignments run from 2016 to 2016. The busiest period was 2015–2019, when 1 prefixes went to 1 carrier. 1 prefixes (50%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. No prefix has been added since 2020: demand for numbers in Flatrock is flat.

Flatrock’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 Distributel in 2016. The most recent arrivals are Distributel (2016), a sign that new carriers are still asking for numbers in Flatrock.

Flatrock has just 2 prefixes (20,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

Distributel leads with 50.0% of the prefixes, but 1 competitors have set up in Flatrock: a market where the incumbent keeps the edge without exclusivity.

Allocation is mature: only 0.0% of the dated prefixes are less than ten years old, most having been handed out in 2015–2019, and 1 prefixes go back to the undated monopoly era. New Flatrock numbers mostly come out of blocks that were assigned long ago.

Dialling a Flatrock number

Flatrock is served by 2 overlaid area codes (236 and 250). A 250 number is no more “out of town” than a 236 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Flatrock shares area codes 236 and 250 with at least 20 other rate centres, including Vancouver, Victoria, Kelowna, Nanaimo, South Kamloops, Prince George, Vernon and Penticton. The largest of them, Vancouver, holds 142 prefixes in 236; the smallest on the list, New Westminster, has just 11.

What a Flatrock number tells you

A number attached to Flatrock tells you that its prefix was issued to a carrier for this rate centre in British Columbia, most often Distributel. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 2 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 Flatrock: code 236-368 is recorded for Distributel, so every 236-368-XXXX number (10,000 possible) descends from that assignment. “Flatrock, British Columbia” there names a rate centre, not a municipality, and several area codes overlay it.
