Dorion’s share of its area code

Within area code 807, Dorion accounts for only 1 of 293 prefixes (0.3%): the code is dominated by Thunder Bay and spread over 85 rate centres.

Who holds these numbers

Bell Canada holds every prefix here. Code by code: Bell Canada is the only holder in 807.

Wireless and wireline

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

Bell Canada is the only carrier ever recorded for Dorion: 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.

Dorion 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: Bell Canada holds every prefix, and no competitor has ever requested a code for Dorion.

Dialling a Dorion number

A single area code, 807, covers Dorion, 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 +1 807 and the seven-digit number.

The numbering neighbourhood

Dorion shares area code 807 with at least 20 other rate centres, including Thunder Bay, Kenora, Fort Frances, Dryden, Marathon, Nipigon, Atikokan and Geraldton. The largest of them, Thunder Bay, holds 67 prefixes in 807; the smallest on the list, Hornepayne, has just 2.

What a Dorion number tells you

A number attached to Dorion tells you that its prefix was issued to a carrier for this rate centre in Ontario, most often Bell Canada. 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 Dorion: code 807-857 is recorded for Bell Canada, so every 807-857-XXXX number (10,000 possible) descends from that assignment. “Dorion, Ontario” there names a rate centre, not a municipality.
