Donnacona’s share of its area codes

Within area code 418, Donnacona accounts for only 10 of 777 prefixes (1.3%): the code is dominated by Quebec and spread over 258 rate centres. Within area code 581, Donnacona accounts for only 7 of 778 prefixes (0.9%): the code is dominated by Quebec and spread over 232 rate centres. Within area code 367, Donnacona accounts for only 4 of 233 prefixes (1.7%): the code is dominated by Quebec and spread over 111 rate centres.

Who holds these numbers

TELUS Quebec holds the largest share at 5 prefixes, 23.8% of the total, ahead of 10 other carriers. Code by code: in 418, TELUS Quebec leads with 3 of 10 prefixes ahead of 6 others; in 581, Videotron Ltd. leads with 3 of 7 prefixes ahead of 3 others; in 367, Iristel Inc. leads with 1 of 4 prefixes ahead of 3 others. 1 carrier holds prefixes in every one of Donnacona’s 3 area codes, while 8 appear in just one.

Wireless and wireline

4 of Donnacona’s 21 prefixes (19.0%) are held by carriers whose registered name marks a wireless business: Bell Mobility, Fido Solutions Inc, Rogers Communications Canada Inc. (Wireless) and TELUS Mobility. Wireline prefixes still outnumber them, carried by TELUS Quebec, Videotron Ltd, Iristel Inc and Bell Canada. 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

Donnacona’s dated assignments run from 2002 to 2025. The busiest period was 2005–2009, when 5 prefixes went to 4 carriers. 2 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 5 prefixes have been added, so the rate centre is still growing.

Donnacona’s oldest prefixes, the ones the register leaves undated, belong to TELUS Quebec: this carrier made up the landscape before competition arrived. The first dated assignment went to TELUS Quebec in 2002. The most recent arrivals are Fibernetics Corporation (2025), Cogeco Connexion Inc. (2025) and ISP Telecom Inc. (2025), a sign that new carriers are still asking for numbers in Donnacona.

Donnacona has only 21 prefixes, or 210,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Donnacona: the leader, TELUS Quebec, holds only 23.8% of the prefixes against 10 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: 26.3% 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 Donnacona number

Donnacona is served by 3 overlaid area codes (418, 581 and 367). A 367 number is no more “out of town” than a 418 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Donnacona shares area codes 418, 581 and 367 with at least 20 other rate centres, including Quebec, Chicoutimi, Alma, Rimouski, Riviere-du-Loup, Thetford Mines, Sainte-Marie-de-Beauce and Levis. The largest of them, Quebec, holds 282 prefixes in 367, 418 and 581; the smallest on the list, Chandler, has just 13.

What a Donnacona number tells you

A number attached to Donnacona tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often TELUS Quebec. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 11 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 Donnacona: code 418-283 is recorded for TELUS Quebec, so every 418-283-XXXX number (10,000 possible) descends from that assignment. “Donnacona, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
