Jeffreys’s share of its area code

Within area code 709, Jeffreys accounts for only 3 of 630 prefixes (0.5%): the code is dominated by St. John's and spread over 209 rate centres.

Who holds these numbers

Aliant Telecom (NF) holds the largest share at 1 prefixes, 33.3% of the total, ahead of 2 other carriers. Code by code: in 709, Aliant Telecom (NF) leads with 1 of 3 prefixes ahead of 2 others.

Wireless and wireline

1 of Jeffreys’s 3 prefixes (33.3%) are held by carriers whose registered name marks a wireless business: Bell Mobility Aliant. Wireline prefixes still outnumber them, carried by Aliant Telecom (NF) and Bragg Communications Inc. This is a sort by name, not a licence lookup, and a mobile prefix may have been ported to another network since.

How the allocation was built up

Jeffreys’s dated assignments run from 2010 to 2010. The busiest period was 2010–2014, when 2 prefixes went to 2 carriers. 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 Jeffreys is flat.

Jeffreys’s oldest prefixes, the ones the register leaves undated, belong to Aliant Telecom (NF): this carrier made up the landscape before competition arrived. The first dated assignment went to Bragg Communications Inc. in 2010. The most recent arrivals are Bell Mobility Aliant (2010) and Bragg Communications Inc. (2010), a sign that new carriers are still asking for numbers in Jeffreys.

Jeffreys 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.

No single carrier dominates Jeffreys: the leader, Aliant Telecom (NF), holds only 33.3% of the prefixes against 2 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Allocation is mature: only 0.0% of the dated prefixes are less than ten years old, most having been handed out in 2010–2014, and 1 prefixes go back to the undated monopoly era. New Jeffreys numbers mostly come out of blocks that were assigned long ago.

Dialling a Jeffreys number

A single area code, 709, covers Jeffreys, 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 +1 709 and the seven-digit number.

The numbering neighbourhood

Jeffreys shares area code 709 with at least 20 other rate centres, including St. John's, Corner Brook, Clarenville, Carbonear, Gander, Marystown, Bay Roberts and Labrador City - Wabush. The largest of them, St. John's, holds 100 prefixes in 709; the smallest on the list, Glovertown, has just 5.

What a Jeffreys number tells you

A number attached to Jeffreys tells you that its prefix was issued to a carrier for this rate centre in Newfoundland and Labrador, most often Aliant Telecom (NF). It does not tell you where the handset is today: a subscriber may have ported the number to any of the 3 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 Newfoundland and Labrador area code is easy to borrow to look local.

Reading a register entry for Jeffreys: code 709-645 is recorded for Aliant Telecom (NF), so every 709-645-XXXX number (10,000 possible) descends from that assignment. “Jeffreys, Newfoundland and Labrador” there names a rate centre, not a municipality.
