Who holds these numbers

Distributel holds the largest share at 2 prefixes, 18.2% of the total, ahead of 8 other carriers. Code by code: in 365, Distributel leads with 1 of 4 prefixes ahead of 3 others; in 506, Distributel leads with 1 of 3 prefixes ahead of 2 others; in 905, Rogers Communications Canada Inc. (Cable) leads with 1 of 2 prefixes ahead of 1 others; InnSysVoice Corp is the only holder in 289; Beanfield Technologies Inc. is the only holder in 742. No carrier holds prefixes in every one of Hampton’s 5 area codes, while 7 appear in just one.

Wireless and wireline

None of Hampton’s holders carries a mobility brand in its registered name: all 11 prefixes belong to wireline or wholesale carriers, among them Distributel, Rogers Communications Canada Inc. (Cable), Aliant Telecom(NB) and Beanfield Technologies Inc. A call showing a Hampton number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Hampton’s dated assignments run from 2004 to 2022. The busiest period was 2020–2024, when 5 prefixes went to 5 carriers. 2 prefixes (18%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 5 prefixes have been added, so the rate centre is still growing.

Hampton’s oldest prefixes, the ones the register leaves undated, belong to Aliant Telecom(NB) and Bell Canada: these carriers made up the landscape before competition arrived. The first dated assignment went to Rogers Communications Canada Inc. (Cable) in 2004. The most recent arrivals are ISP Telecom Inc. (2022), Fibernetics Corporation (2021) and Beanfield Technologies Inc. (2021), a sign that new carriers are still asking for numbers in Hampton.

Hampton has only 11 prefixes, or 110,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Hampton: the leader, Distributel, holds only 18.2% of the prefixes against 8 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Growth is recent: 55.6% of the dated prefixes were assigned in the last ten years, peaking in 2020–2024. Hampton is among the rate centres where demand for numbers is still rising quickly.

Dialling a Hampton number

Hampton is served by 5 overlaid area codes (365, 506, 905, 289 and 742). A 742 number is no more “out of town” than a 365 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Hampton shares area codes 365, 506, 905, 289 and 742 with at least 20 other rate centres, including Hamilton, Brampton, Oshawa, St. Catharines-Thorold, Oakville, Markham, Moncton and Ajax-Pickering. The largest of them, Hamilton, holds 221 prefixes in 289, 365, 742 and 905; the smallest on the list, Milton, has just 41.

What a Hampton number tells you

A number attached to Hampton tells you that its prefix was issued to a carrier for this rate centre in Ontario, most often Distributel. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 9 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 Hampton: code 365-403 is recorded for Distributel, so every 365-403-XXXX number (10,000 possible) descends from that assignment. “Hampton, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
