British Columbia is currently using three area codes. British Columbia has had one area code split and one area code overlay
plan, often called an overlay complex.
Area code 604 originally covered all of British Columbia. This was sufficient for forty-nine years until 1996 when British Columbia experienced sufficient growth in
population and telephone use to need an additional area code. To meet the demand area code 604 was split to form 250. The growth in British Columbia continued especially in the Greater Vancouver area, as well as,
Abbotsford and Mission. To meet this continuing demand for new telephone numbers area code 778 was introduced as a concentrated overlay of those areas. In 2008 area code 778 was expanded to cover all of area code 604
and 250.
