History of the 587 area code

The 587 area code went into service in 2008 as a provincewide overlay for Alberta. Before that, the province was split between 403 in the south and 780 in the north. Rather than redrawing those boundaries, 587 was layered over the entire province so new numbers could be issued anywhere. Later overlays 825 (2015) and 368 (2021) joined the same pool, and all of them require ten-digit dialing.
