Stoneham’s share of its area codes

Within area code 581, Stoneham accounts for only 4 of 778 prefixes (0.5%): the code is dominated by Quebec and spread over 232 rate centres. Within area code 418, Stoneham accounts for only 3 of 777 prefixes (0.4%): the code is dominated by Quebec and spread over 258 rate centres.

Who holds these numbers

Videotron Ltd. holds the largest share at 2 prefixes, 28.6% of the total, ahead of 5 other carriers. Code by code: in 581, Distributel leads with 1 of 4 prefixes ahead of 3 others; in 418, Videotron Ltd. leads with 2 of 3 prefixes ahead of 1 others. No carrier holds prefixes in every one of Stoneham’s 2 area codes, while 6 appear in just one.

Wireless and wireline

None of Stoneham’s holders carries a mobility brand in its registered name: all 7 prefixes belong to wireline or wholesale carriers, among them Videotron Ltd, Bell Canada, Distributel and Fibernetics Corporation. A call showing a Stoneham number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Stoneham’s dated assignments run from 2007 to 2021. The busiest period was 2005–2009, when 2 prefixes went to 1 carrier. 1 prefixes (14%) 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.

Stoneham’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada: this carrier made up the landscape before competition arrived. The first dated assignment went to Videotron Ltd. in 2007. The most recent arrivals are Fibernetics Corporation (2021), ISP Telecom Inc. (2020) and Distributel (2018), a sign that new carriers are still asking for numbers in Stoneham.

Stoneham has just 7 prefixes (70,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Stoneham: the leader, Videotron Ltd., holds only 28.6% of the prefixes against 5 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: 33.3% of the dated prefixes go back to the last ten years, the most active period being 2005–2009. The rate centre is growing at a regular rather than explosive pace.

Dialling a Stoneham number

Stoneham is served by 2 overlaid area codes (581 and 418). A 418 number is no more “out of town” than a 581 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Stoneham shares area codes 581 and 418 with at least 20 other rate centres, including Quebec, Chicoutimi, Rimouski, Alma, Riviere-du-Loup, Thetford Mines, Levis and Saint-Georges-de-Beauce. The largest of them, Quebec, holds 245 prefixes in 418 and 581; the smallest on the list, Chibougamau, has just 11.

What a Stoneham number tells you

A number attached to Stoneham tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often Videotron Ltd.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 6 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 Quebec area code is easy to borrow to look local.

Reading a register entry for Stoneham: code 418-384 is recorded for Videotron Ltd., so every 418-384-XXXX number (10,000 possible) descends from that assignment. “Stoneham, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
