Morin Heights’s share of its area codes

Within area code 450, Morin Heights accounts for only 2 of 775 prefixes (0.3%): the code is dominated by Granby and spread over 129 rate centres. Within area code 579, Morin Heights accounts for only 1 of 644 prefixes (0.2%): the code is dominated by Granby and spread over 126 rate centres.

Who holds these numbers

TELUS Quebec holds the largest share at 2 prefixes, 66.7% of the total, ahead of 1 other carrier. Code by code: in 450, TELUS Quebec leads with 1 of 2 prefixes ahead of 1 others; TELUS Quebec is the only holder in 579. 1 carrier holds prefixes in every one of Morin Heights’s 2 area codes, while 1 appears in just one.

Wireless and wireline

None of Morin Heights’s holders carries a mobility brand in its registered name: all 3 prefixes belong to wireline or wholesale carriers, among them TELUS Quebec and Bell Canada. A call showing a Morin Heights number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Morin Heights’s dated assignments run from 2008 to 2017. The busiest period was 2005–2009, when 1 prefixes went to 1 carrier. 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 Morin Heights is flat.

Morin Heights’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 TELUS Quebec in 2008. The most recent arrivals are TELUS Quebec (2008), a sign that new carriers are still asking for numbers in Morin Heights.

Morin Heights 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.

TELUS Quebec leads with 66.7% of the prefixes, but 1 competitors have set up in Morin Heights: a market where the incumbent keeps the edge without exclusivity.

Allocation is mature: only 0.0% of the dated prefixes are less than ten years old, most having been handed out in 2005–2009, and 1 prefixes go back to the undated monopoly era. New Morin Heights numbers mostly come out of blocks that were assigned long ago.

Dialling a Morin Heights number

Morin Heights is served by 2 overlaid area codes (450 and 579). A 579 number is no more “out of town” than a 450 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Morin Heights shares area codes 450 and 579 with at least 20 other rate centres, including Granby, Joliette, St-Jerome, St-Hyacinthe, Longueuil, Ste-Therese, Pont-Viau and Sorel. The largest of them, Granby, holds 51 prefixes in 450 and 579; the smallest on the list, Lachute, has just 17.

What a Morin Heights number tells you

A number attached to Morin Heights 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 2 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 Morin Heights: code 450-644 is recorded for TELUS Quebec, so every 450-644-XXXX number (10,000 possible) descends from that assignment. “Morin Heights, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
