'Hi, is this Sarah?' — the $10B wrong-number text scam

The friendly wrong-number text is the entry point to pig butchering. How it works, why you should never reply, and what to do if you did.

2026-05-25 4 min read

That polite text from a stranger asking if you're "Sarah from the yoga class" is almost never a wrong number. It's the opening line of the most lucrative scam funnel in history.

Why it works

The scammer doesn't ask for money. They ask for nothing. They simply want you to reply — to confirm the number is active and that you're the kind of person who answers strangers politely. Once you do, you're moved to a longer-term grooming track that ends in pig butchering (see our pig butchering playbook).

The patterns

  • "Sorry, wrong number! But your photo is cute 😊"
  • "Mr. Wang? This is about the import shipment."
  • "Hi, this is Linda from the dental clinic, your appointment is confirmed."
  • "Hi! Are we still meeting tomorrow at 7?"

Do this instead

  1. Don't reply. Don't even send "wrong number".
  2. Long-press the message → Block & Report Junk (iOS) or Block & Report Spam (Android).
  3. Paste the number into the GACS Safe Scanner to see if it's already in our database.
  4. Forward the text to 7726 (SPAM) in the US, UK, Canada, and Australia — your carrier feeds it to law enforcement.

Frequently asked questions

What is a wrong-number text scam?+

An unsolicited text that opens with 'Hi, is this Sarah?' or similar. The goal is to start a friendly conversation that pivots to crypto investment within a week or two — the entry point to pig butchering.

Should I reply to a wrong-number text to be polite?+

No. Any reply confirms the number is active and escalates the targeting. Block the number and forward the message to 7726 (SPAM) in the US, UK, Canada, and Australia.

Why do scammers use wrong-number openers?+

It bypasses spam filters that catch obvious scam phrases, and a friendly correction feels low-pressure — which is exactly what makes it work.
