Chester’s share of its area codes

Within area code 902, Chester accounts for only 10 of 782 prefixes (1.3%): the code is dominated by Halifax and spread over 175 rate centres. Within area code 782, Chester accounts for only 5 of 456 prefixes (1.1%): the code is dominated by Halifax and spread over 142 rate centres.

Who holds these numbers

Aliant Telecom (NS) holds the largest share at 2 prefixes, 13.3% of the total, ahead of 10 other carriers. Code by code: in 902, Aliant Telecom (NS) leads with 2 of 10 prefixes ahead of 7 others; in 782, Fibernetics Corporation leads with 2 of 5 prefixes ahead of 3 others. 1 carrier holds prefixes in every one of Chester’s 2 area codes, while 10 appear in just one.

Wireless and wireline

4 of Chester’s 15 prefixes (26.7%) are held by carriers whose registered name marks a wireless business: Bell Mobility Aliant, Fido Solutions Inc, Rogers Communications Canada Inc. (Wireless) and TELUS Mobility. Wireline prefixes still outnumber them, carried by Aliant Telecom (NS), Bragg Communications Inc, Fibernetics Corporation and Iristel 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

Chester’s dated assignments run from 2000 to 2023. The busiest period was 2020–2024, when 4 prefixes went to 3 carriers. 3 prefixes (20%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 4 prefixes have been added, so the rate centre is still growing.

Chester’s oldest prefixes, the ones the register leaves undated, belong to Aliant Telecom (NS) and Bell Mobility Aliant: these carriers made up the landscape before competition arrived. The first dated assignment went to Bragg Communications Inc. in 2000. The most recent arrivals are ISP Telecom Inc. (2021), Fibernetics Corporation (2021) and Distributel (2018), a sign that new carriers are still asking for numbers in Chester.

Chester has only 15 prefixes, or 150,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Chester: the leader, Aliant Telecom (NS), holds only 13.3% of the prefixes against 10 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Demand remains steady: 33.3% of the dated prefixes go back to the last ten years, the most active period being 2020–2024. The rate centre is growing at a regular rather than explosive pace.

Dialling a Chester number

Chester is served by 2 overlaid area codes (902 and 782). A 782 number is no more “out of town” than a 902 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Chester shares area codes 902 and 782 with at least 20 other rate centres, including Halifax, Charlottetown, Sydney, Truro, Amherst, New Glasgow, Kentville and Summerside. The largest of them, Halifax, holds 220 prefixes in 782 and 902; the smallest on the list, Port Hawkesbury, has just 12.

What a Chester number tells you

A number attached to Chester tells you that its prefix was issued to a carrier for this rate centre in Nova Scotia, most often Aliant Telecom (NS). It does not tell you where the handset is today: a subscriber may have ported the number to any of the 11 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 Nova Scotia area code is easy to borrow to look local.

Reading a register entry for Chester: code 902-275 is recorded for Aliant Telecom (NS), so every 902-275-XXXX number (10,000 possible) descends from that assignment. “Chester, Nova Scotia” there names a rate centre, not a municipality, and several area codes overlay it.
