Area Code 604 History:
Area code 604 was officially put into service. In 1996 area code 604 was split to form area code 250. In 2001 area code 604 was partially overlaid with area code 778. In 2008 the overlay was expanded to include all of area code 604 and area code 250. Area code 604 serves all of the lower mainland in British Columbia.
Area code 236 was officially put into service as an overlay of area codes 250, 604, and 778 on 06/01/2013 and mandatory 10 digit dialing is required.
Area code 672 was officially put into service as an overlay of area codes 236, 250, 604, and 778 on 05/04/2019.
Ten digit dialing (area code + seven digit number) is necessary in the 604/778/236 overlay because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
