🛡️ Is 878 Area Code Spam or Scam?

Seeing 878 on your caller ID doesn’t automatically mean spam — it’s a real area code used by many in Pittsburgh. But robocallers frequently disguise their actual numbers behind familiar area codes like 878. If a 878 call feels off, hang up and verify independently.

⚠️ Red Flag: If a 878 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.
