🛡️ Is 604 Area Code Spam or Scam?

Area code 604 is 100% legitimate — it serves Vancouver, British Columbia. The problem is that scammers spoof 604 numbers constantly because people trust local-looking calls. The most common 604 scams involve fake utility shutoff threats, vehicle warranty extensions, and Social Security impersonation.

⚠️ Red Flag: If a 604 caller demands immediate payment via gift cards, wire transfer, or crypto — hang up. No legitimate organization uses these methods. Verify by calling the company’s official number directly.

How to verify: Don’t call back the number — look up the official number for whatever organization the caller claimed to represent and call that instead. Google the full 10-digit number in quotes to check if others have reported it as spam.
