How the allocation was built up

The busiest period was 2010–2014, when 1 prefixes went to 1 carrier. 1 prefixes (50%) 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 Jean Marie River is flat.

Jean Marie River’s oldest prefixes, the ones the register leaves undated, belong to Northwestel: this carrier made up the landscape before competition arrived. The first dated assignment went to Bell Mobility in 2013. The most recent arrivals are Bell Mobility (2013), a sign that new carriers are still asking for numbers in Jean Marie River.

Jean Marie River has just 2 prefixes (20,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

Bell Mobility leads with 50.0% of the prefixes, but 1 competitors have set up in Jean Marie River: a market where the incumbent keeps the edge without exclusivity.

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 Jean Marie River numbers mostly come out of blocks that were assigned long ago.

What a Jean Marie River number tells you
