Gravelbourg’s share of its area codes

Within area code 306, Gravelbourg accounts for only 3 of 777 prefixes (0.4%): the code is dominated by Saskatoon and spread over 228 rate centres. Within area code 639, Gravelbourg accounts for only 1 of 776 prefixes (0.1%): the code is dominated by Regina and spread over 202 rate centres.

Who holds these numbers

Bell Mobility holds the largest share at 1 prefixes, 25.0% of the total, ahead of 3 other carriers. Code by code: in 306, SaskTel leads with 1 of 3 prefixes ahead of 2 others; Bell Mobility is the only holder in 639. No carrier holds prefixes in every one of Gravelbourg’s 2 area codes, while 4 appear in just one.

Wireless and wireline

3 of Gravelbourg’s 4 prefixes (75.0%) are held by carriers whose registered name marks a wireless business: Bell Mobility, SaskTel Mobility and TELUS Mobility. That makes this a mostly mobile rate centre, which is typical of recent allocations: new prefixes go overwhelmingly to cellphones. 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

Gravelbourg’s dated assignments run from 2010 to 2017. The busiest period was 2010–2014, when 2 prefixes went to 2 carriers. 1 prefixes (25%) 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 Gravelbourg is flat.

Gravelbourg’s oldest prefixes, the ones the register leaves undated, belong to SaskTel: this carrier made up the landscape before competition arrived. The first dated assignment went to SaskTel Mobility in 2010. The most recent arrivals are Bell Mobility (2017), TELUS Mobility (2010) and SaskTel Mobility (2010), a sign that new carriers are still asking for numbers in Gravelbourg.

Gravelbourg has just 4 prefixes (40,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Gravelbourg: the leader, Bell Mobility, holds only 25.0% of the prefixes against 3 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 Gravelbourg numbers mostly come out of blocks that were assigned long ago.

Dialling a Gravelbourg number

Gravelbourg is served by 2 overlaid area codes (306 and 639). A 639 number is no more “out of town” than a 306 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Gravelbourg shares area codes 306 and 639 with at least 20 other rate centres, including Regina, Saskatoon, Moose Jaw, Prince Albert, North Battleford, Yorkton, Swift Current and Moosomin. The largest of them, Regina, holds 157 prefixes in 306 and 639; the smallest on the list, Rosthern, has just 12.

What a Gravelbourg number tells you

A number attached to Gravelbourg tells you that its prefix was issued to a carrier for this rate centre in Saskatchewan, most often Bell Mobility. It does not tell you where the handset is today: most of Gravelbourg’s prefixes are mobile, and a cellphone keeps its number when its owner moves across the country. Nor does it tell you who is calling: caller ID can be spoofed, and a Saskatchewan area code is easy to borrow to look local.

Reading a register entry for Gravelbourg: code 639-828 is recorded for Bell Mobility, so every 639-828-XXXX number (10,000 possible) descends from that assignment. “Gravelbourg, Saskatchewan” there names a rate centre, not a municipality, and several area codes overlay it.

2. Report the fraud

   Report the call or text to the Canadian Anti-Fraud Centre online or at 1-888-495-8501. If you lost money or gave out personal details, tell your bank first, then your local police.

3. Register on the National Do Not Call List
