WhatsApp 6-digit code account hijack scam

Impersonating: WhatsApp

What is this scam?

A message appears from a known contact's WhatsApp asking you to forward a 6-digit SMS code you've just received. The code is WhatsApp's device-transfer authentication — sharing it hands the scammer instant full access to your account, locking you out completely.

Example scam message

Hey! Sorry to bother you, I accidentally sent a verification code to your number instead of mine. Could you forward it to me? Really urgent, thanks

Red flags to look out for

  • Links lead to unofficial domains that don't match the real company's website.
  • You weren't expecting this message and can't verify the event it references.
  • It asks you to confirm payment details or personal information via a link.
  • The sender's number or email address doesn't match the company's official contact.
