🛡️ Is 840 Area Code Spam or Scam?

Like most US area codes, 840 is used by both legitimate callers and scammers. The code itself is perfectly real — millions of people and businesses in Roanoke use it daily. But scammers frequently spoof 840 numbers because local-looking calls get answered more often than unfamiliar ones.

⚠️ Red Flag: If a 840 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.
