The "Guess Who" WhatsApp Scam: How It Works and Why It's Spreading
TL;DR: The "guess who" scam starts with a WhatsApp message from an unknown number claiming to be a relative or friend texting from a new phone. Once you guess a name, the scammer adopts it and builds trust before asking for money — usually for an urgent, embarrassing, or time-sensitive reason.

This scam has been flagged as a rising trend across several countries in 2026, and it's spreading in India through the same mechanic — playing on the very ordinary experience of a contact texting from a number you don't recognize.
How the script runs
- A message arrives from an unsaved number: "Hi, guess who this is!" or "I lost my old phone, this is my new number."
- If you guess a name — a cousin, an old classmate, a family friend — the scammer confirms it and adopts that identity for the rest of the conversation.
- Over the following messages (sometimes days), they build rapport, referencing vague shared history that could apply to almost anyone.
- Eventually, they introduce an urgent need for money — a medical emergency, a stuck bill payment, or a request to "forward" an OTP they claim was sent to your number by mistake.
Why guessing the name matters so much
The scam depends entirely on you supplying the identity. Once you say "Is this Priya?", the scammer simply becomes Priya — no research required on their part. This is what makes it scalable: the same opening message works against thousands of recipients with zero customization.
The verification step that stops it every time
Never confirm a new number is genuinely who they claim to be based on the conversation alone. Call the person's known, saved number directly, or ask a question only the real person could answer without it being guessable from a WhatsApp profile or public information. If they resist a phone call or video call specifically, that resistance is itself a strong signal.
The specific request to watch for
If the conversation moves toward a request to forward an OTP "sent to your number by mistake," stop immediately — no legitimate scenario requires this, and sharing it can hand over control of an account or authorize a payment. See Why You Should Never Share an OTP for why this specific request is always disqualifying.
What to do if you've already sent money
Treat this exactly like any financial fraud — call 1930 immediately, and see the Golden Hour guide for the process. Report and block the number on WhatsApp regardless of outcome, and warn the actual person whose identity was used, since the scammer may attempt the same script against others in the same contact network.
It's also worth reviewing your WhatsApp privacy settings — limiting who can see your number and profile photo makes this specific scam somewhat harder to personalize.

Frequently Asked Questions
How does the scammer know who to pretend to be?
They don't — the scam depends on you supplying a guess ('Is this Priya?'), which the scammer then simply adopts. No prior research about you is required for this specific tactic to work.
What's the fastest way to verify a new number claiming to be someone I know?
Call the person's existing, saved number directly, or ask something only they could answer that isn't guessable from public information — resistance to a phone or video call is itself a red flag.
Why is a request to forward an OTP always a red flag in this scam?
There's no legitimate reason anyone would need you to forward an OTP 'sent to your number by mistake' — sharing it can hand over account access or authorize a payment on the scammer's behalf.
Should I report the number even if I didn't send money?
Yes — report and block it on WhatsApp, and consider warning the real contact whose identity was impersonated, since the same script is often reused against their broader network.
Can adjusting my WhatsApp privacy settings help prevent this?
It can reduce how easily a scammer personalizes the approach — limiting visibility of your number and profile photo to contacts only makes the opening message slightly harder to make convincing.
