Cover card with a chat bubble and warning icon, for a WhatsApp wrong number scam after you replied.
Short answer

A "wrong number" WhatsApp message is often the start of a romance or investment scam. If you only replied, stop chatting, block and report the number. If you shared personal details, watch for phishing. If you sent money or joined an investment app, contact your bank and report to police or your national scam line straight away.

Summary
  • Wrong-number openers lead to romance or investment scams.
  • Replying alone is low risk.
  • Block and report the number.
  • Never move money to apps they suggest.
  • Report losses quickly.

#What common mistakes should I avoid?

  • Continuing the chat out of politeness.
  • Installing apps they suggest.
  • Sending a small 'test' payment.
  • Not reporting the number.

#When should I ask an expert before I act?

Ask for help before you appeal if the account matters to your income, your business or your memories, if you have already had one appeal rejected, or if you cannot tell whether the problem is a bug, a restriction or a hack. That is where most avoidable losses happen.
