Clova’s share of its area code

Within area code 819, Clova accounts for only 1 of 770 prefixes (0.1%): the code is dominated by Ottawa-Hull and spread over 211 rate centres.

Who holds these numbers

Telebec Ltee. holds every prefix here. Code by code: Telebec Ltee. is the only holder in 819.

Wireless and wireline

None of Clova’s holders carries a mobility brand in its registered name: all 1 prefixes belong to wireline or wholesale carriers, among them Telebec Ltee. A call showing a Clova number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

The register dates none of Clova’s assignments: all 1 prefixes predate CNAC’s record-keeping, the signature of an old, settled network where nothing has been added in decades.

Telebec Ltee. is the only carrier ever recorded for Clova: no competitor has obtained a prefix here. A single-carrier rate centre is typical of small communities where only the incumbent ever built a network.

Clova has just 1 prefix (10,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

The local market is an allocation monopoly: Telebec Ltee. holds every prefix, and no competitor has ever requested a code for Clova.

Dialling a Clova number

A single area code, 819, covers Clova, and it is not overlaid with any other code on this territory: one of the few parts of Canada where seven-digit local dialling may still work. From abroad, dial +1 819 and the seven-digit number.

The numbering neighbourhood

Clova shares area code 819 with at least 20 other rate centres, including Ottawa-Hull, Sherbrooke, Trois-Rivieres, Drummondville, Val-D'Or, Gatineau, Shawinigan and Rouyn-Noranda. The largest of them, Ottawa-Hull, holds 83 prefixes in 819; the smallest on the list, Plessisville, has just 6.

What a Clova number tells you

A number attached to Clova tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often Telebec Ltee.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 1 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 Clova: code 819-662 is recorded for Telebec Ltee., so every 819-662-XXXX number (10,000 possible) descends from that assignment. “Clova, Quebec” there names a rate centre, not a municipality.
