Altona’s share of its area codes

Within area code 204, Altona accounts for only 5 of 781 prefixes (0.6%): the code is dominated by Winnipeg and spread over 245 rate centres. Within area code 431, Altona accounts for only 5 of 572 prefixes (0.9%): the code is dominated by Winnipeg and spread over 146 rate centres.

Who holds these numbers

MTS Inc. holds the largest share at 3 prefixes, 30.0% of the total, ahead of 7 other carriers. Code by code: in 204, MTS Inc. leads with 3 of 5 prefixes ahead of 2 others; in 431, Bell Mobility leads with 1 of 5 prefixes ahead of 4 others. No carrier holds prefixes in every one of Altona’s 2 area codes, while 8 appear in just one.

Wireless and wireline

3 of Altona’s 10 prefixes (30.0%) are held by carriers whose registered name marks a wireless business: Bell Mobility, Rogers Communications Canada Inc. (Wireless) and TELUS Mobility. Wireline prefixes still outnumber them, carried by MTS Inc, Bell West Inc, LES.NET (1996) Inc and Provincial Tel 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

Altona’s dated assignments run from 2003 to 2022. The busiest period was 2015–2019, when 3 prefixes went to 3 carriers. 1 prefixes (10%) 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.

Altona’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 MTS Inc. in 2003. The most recent arrivals are TELUS Integrated Communications (2022), LES.NET (1996) Inc. (2020) and Bell West Inc. (2019), a sign that new carriers are still asking for numbers in Altona.

Altona has only 10 prefixes, or 100,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Altona: the leader, MTS Inc., holds only 30.0% of the prefixes against 7 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: 22.2% of the dated prefixes go back to the last ten years, the most active period being 2015–2019. The rate centre is growing at a regular rather than explosive pace.

Dialling a Altona number

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

The numbering neighbourhood

Altona shares area codes 204 and 431 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, Austin, has just 9.

What a Altona number tells you

A number attached to Altona tells you that its prefix was issued to a carrier for this rate centre in Manitoba, most often MTS Inc.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 8 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 Altona: code 204-304 is recorded for MTS Inc., so every 204-304-XXXX number (10,000 possible) descends from that assignment. “Altona, Manitoba” there names a rate centre, not a municipality, and several area codes overlay it.
