🛡️ Is 442 Area Code Spam or Scam?

If an unexpected 442 caller asks for personal info or payment, that’s your red flag.

⚠️ Red Flag: If a 442 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.
