🛡️ Is 387 Area Code Spam or Scam?

The 387 area code is completely legitimate, covering real residents and businesses in Kitchener. However, spam callers love spoofing well-known area codes like 387 because you’re more likely to pick up a local-looking number. If an unexpected 387 caller asks for personal info or payment, that’s your red flag.

⚠️ Red Flag: If a 387 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.
