Rossburn’s share of its area codes

Within area code 431, Rossburn accounts for only 2 of 572 prefixes (0.3%): the code is dominated by Winnipeg and spread over 146 rate centres. Within area code 204, Rossburn accounts for only 1 of 781 prefixes (0.1%): the code is dominated by Winnipeg and spread over 245 rate centres.

Who holds these numbers

Bell Mobility holds the largest share at 1 prefixes, 33.3% of the total, ahead of 2 other carriers. Code by code: in 431, Bell Mobility leads with 1 of 2 prefixes ahead of 1 others; MTS Inc. is the only holder in 204. No carrier holds prefixes in every one of Rossburn’s 2 area codes, while 3 appear in just one.

Wireless and wireline

1 of Rossburn’s 3 prefixes (33.3%) are held by carriers whose registered name marks a wireless business: Bell Mobility. Wireline prefixes still outnumber them, carried by MTS Inc and Westman Media Cooperative Ltd. 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

Rossburn’s dated assignments run from 2017 to 2017. The busiest period was 2015–2019, when 2 prefixes went to 2 carriers. 1 prefixes (33%) 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 Rossburn is flat.

Rossburn’s oldest prefixes, the ones the register leaves undated, belong to MTS Inc: this carrier made up the landscape before competition arrived. The first dated assignment went to Bell Mobility in 2017. The most recent arrivals are Westman Media Cooperative Ltd (2017) and Bell Mobility (2017), a sign that new carriers are still asking for numbers in Rossburn.

Rossburn has just 3 prefixes (30,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Rossburn: the leader, Bell Mobility, holds only 33.3% of the prefixes against 2 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 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 Rossburn numbers mostly come out of blocks that were assigned long ago.

Dialling a Rossburn number

Rossburn is served by 2 overlaid area codes (431 and 204). A 204 number is no more “out of town” than a 431 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Rossburn shares area codes 431 and 204 with at least 20 other rate centres, including Winnipeg, Brandon, Portage La Prairie, Steinbach, Oakbank, Stonewall, Dauphin and Selkirk. The largest of them, Winnipeg, holds 387 prefixes in 204 and 431; the smallest on the list, The Pas, has just 10.

What a Rossburn number tells you

A number attached to Rossburn tells you that its prefix was issued to a carrier for this rate centre in Manitoba, most often Bell Mobility. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 3 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 Manitoba area code is easy to borrow to look local.

Reading a register entry for Rossburn: code 431-286 is recorded for Bell Mobility, so every 431-286-XXXX number (10,000 possible) descends from that assignment. “Rossburn, Manitoba” there names a rate centre, not a municipality, and several area codes overlay it.
