Cogeco phone number blocks and OCNs in Canada

Cogeco holds 1.6 million phone numbers in Canada, 0.5% of the numbers CNAC’s table of 2026-09-24 lists as allocated there, under 1 operating company number (OCN). The carrier a phone lookup names for a number is the holder of the block the number sits in, as the regulator lists it: the original allocation, not the caller, the app or the network that serves a ported number today.

The legal entities CNAC lists

Every holder in CNAC’s table that the brand map groups under Cogeco, by the numbers allocated to it and with its operating company number (OCN), the code the table identifies a carrier by. Names are printed as the regulator writes them. Holdings are counted in numbers, not table rows, because rows differ in size: a central office code (NPA-NXX) is 10,000 numbers.

How a lookup reads these numbers

The North American plan leaves a number’s line type to the holder of its block, so a lookup reads it from the holder: 0.0% of Cogeco’s numbers read as VoIP, 0.0% as mobile, and for 100.0% the holder settles neither, so the line type stays fixed_line_or_mobile.

The reading is Spaw’s classification of each holder: the holder’s regulatory filing (in the US its FCC Form 499 filing type) and its own description, matched on the name the regulator’s table gives it. It is a lower bound, not a measurement of the numbers, and it says what a lookup answers, not what Cogeco is.

The area codes with most of its numbers

Cogeco’s entities hold numbers under 12 area codes. The share is its part of the numbers CNAC lists as allocated under each code.

code	place	numbers	share of the code

Assignments by year

The codes the table still lists under Cogeco’s entities, by the year CNAC dates their assignment. A block returned since is no longer in the table, so earlier years read low; 100.0% of the rows carry a date.

year	codes	numbers
2026	35	350,000
2025	105	1.1 million
2024	13	130,000
2023	2	20,000

What this page cannot say

A regulator’s table records the original allocation of each block, never who serves a number today: a number ported away from Cogeco keeps its block, and a lookup still names the block’s holder for it.
The carrier a lookup names is not the caller, the app or the subscriber. Caller ID can be spoofed, so the holder of a calling number’s block may not have carried the call at all.
Spaw does no reverse lookup and names no subscriber: nothing here says who owns or uses any number.
Shares are shares of the regulator’s own table, not of subscribers, lines in service or traffic.
In a pooled US code a lookup names the holder of the number’s own thousands-block where NANPA lists one, otherwise the code holder; Canada’s table is code-level.
The grouping under Cogeco is Spaw’s carrier brand map of 2026-09-24: legal entities, subsidiaries and former names under the brand the network trades as today. Networks change hands, and the map is reviewed at least yearly.

Cogeco and the other brand names on this page are trademarks of their owners, used only to name the networks the regulators’ tables list. Spaw is not affiliated with any of them.
