Find any 604- phone number in British Columbia
The 604 area code serves the province of British Columbia in Canada. It was one of the original 86 area codes established by AT&T in 1947. 604 and neighboring region area code 250 jointly cover the entire province. In the 604 area code region, the area code is typically followed by a seven-digit local number.
The 604 area code is part of the North American Numbering Plan (NANP). This is a coordinated numbering plan that allows a single telephone number to be used for multi-regional calling and routing. It is jointly administered by the governments of Canada, the United States, and its territories. The plan organizes telephone numbers into area codes, exchanges, and the four-digit local subscriber number. The NANP allows people from different regions to be able to contact each other without the need for complicated international dialing systems. This is why the 604 area code is part of the NANP and why it is used in British Columbia.
