Cambray’s share of its area code

Within area code 705, Cambray accounts for only 1 of 770 prefixes (0.1%): the code is dominated by Barrie and spread over 203 rate centres.

Who holds these numbers

Persona Communications Inc. holds every prefix here. Code by code: Persona Communications Inc. is the only holder in 705.

Wireless and wireline

None of Cambray’s holders carries a mobility brand in its registered name: all 1 prefixes belong to wireline or wholesale carriers, among them Persona Communications Inc. A call showing a Cambray 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 Cambray’s assignments: all 1 prefixes predate CNAC’s record-keeping, the signature of an old, settled network where nothing has been added in decades.

Persona Communications Inc. is the only carrier ever recorded for Cambray: 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.

Cambray 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: Persona Communications Inc. holds every prefix, and no competitor has ever requested a code for Cambray.

Dialling a Cambray number

A single area code, 705, covers Cambray, 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 +1 705 and the seven-digit number.

The numbering neighbourhood

Cambray shares area code 705 with at least 20 other rate centres, including Barrie, Sudbury, Peterborough, Sault Ste. Marie, North Bay, Lindsay, Timmins and Orillia. The largest of them, Barrie, holds 71 prefixes in 705; the smallest on the list, Blezard Valley, has just 6.

What a Cambray number tells you

A number attached to Cambray tells you that its prefix was issued to a carrier for this rate centre in Ontario, most often Persona Communications Inc.. 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 an Ontario area code is easy to borrow to look local.

Reading a register entry for Cambray: code 705-374 is recorded for Persona Communications Inc., so every 705-374-XXXX number (10,000 possible) descends from that assignment. “Cambray, Ontario” there names a rate centre, not a municipality.
