Frequently asked about 604
Where is area code 604?
British Columbia. It covers the same area as 236/257/604/672/778.
Can I still get a 604 number?

Not by itself. 604 drew 375 FTC complaints in the 33 days to 30 October 2026, 261st of 422 ranked codes – mid-pack or lower. Spam callers spoof caller IDs, so the only useful check is the full number. The most reported category here is “Reducing your debt (credit cards, mortgage, student loans)”.

Yes – ten digits for local calls in 604, because it shares its area with another code.
