OTP Fraud — How Scammers Trick You Into Sharing OTP
OTP fraud is one of the most common and devastating scams in India. Scammers use social engineering to convince you to hand over the one thing standing between them and your money — your One-Time Password.
How OTP Fraud Works
OTP fraud follows a predictable social engineering chain. Understanding each step makes it far easier to recognize and stop the attack before it succeeds.
Initial contact — impersonation
The scammer contacts you by phone call, SMS, or WhatsApp, pretending to be someone you trust: your bank, a delivery service like Amazon or Flipkart, a government agency like RBI or Income Tax, or even your telecom provider. They may use caller ID spoofing to make the call appear to come from an official number.
Creating urgency and fear
They fabricate a crisis: your account has been compromised, a large unauthorized transaction was detected, your KYC has expired and your account will be frozen, a legal notice has been filed against you, or your delivery will be cancelled. The goal is to make you panic so you stop thinking critically.
Requesting the OTP
Now that you are anxious and want to resolve the 'problem' immediately, the scammer asks you to share the OTP that was just sent to your phone. They frame it as a 'verification code', 'cancellation code', or 'security code' — anything to make sharing it feel like the right thing to do.
Account takeover — damage done
The moment you share the OTP, the scammer uses it to authorize a transaction, log into your account, change your credentials, or link your account to their device. The entire process takes seconds. By the time you realize what happened, the money is already gone.
Real Examples of OTP Fraud Messages
These are real-world scam messages and call scripts reported by victims across India. Can you spot what makes each one dangerous?
“Your SBI account has been debited Rs 49,999. If this was not you, share the OTP sent to your phone for reversal.”
Why this is a scam: Banks never ask you to share OTP for reversals. If an unauthorized debit occurred, the bank initiates reversal on their end — no OTP is needed from you.
“Amazon delivery: Your package couldn't be delivered. Share OTP to reschedule: https://amzn-delivery.co”
Why this is a scam: The URL 'amzn-delivery.co' is not an Amazon domain. Amazon never asks for OTPs via SMS to reschedule deliveries. Rescheduling is done through the Amazon app or website.
“This is the RBI. Your account is under investigation. Share the verification code sent to your number immediately.”
Why this is a scam: The RBI does not contact individuals via WhatsApp or SMS. The RBI does not investigate individual bank accounts. No government agency will ever ask for your OTP.
“Sir, I'm calling from HDFC fraud department. A transaction of Rs 25,000 was attempted. I'm sending an OTP — please read it to me to block the transaction.”
Why this is a scam: Real bank fraud departments block suspicious transactions automatically. They do not call you to ask for an OTP. If your bank detects fraud, they freeze the transaction first and contact you later for verification through secure channels.
Red Flags — How to Spot OTP Fraud
If you notice any of these signs, you are likely dealing with an OTP scammer.
Unsolicited contact about your account
You receive a call, SMS, or WhatsApp message about a problem you did not report — a blocked account, suspicious transaction, or failed delivery.
Extreme urgency or threats
The caller says your account will be permanently blocked, money will be lost, or legal action will be taken unless you act immediately.
Request to share or read out an OTP
Any request to share, forward, or read aloud an OTP is a scam. Full stop. No legitimate service requires this.
Caller ID spoofing
The call appears to come from your bank's official number or a government agency. Caller IDs can be faked — the number you see is not proof of identity.
Suspicious links in messages
The message contains a link to a website that looks like your bank but has a slightly different URL — like sbi-secure.co instead of onlinesbi.sbi.
Request to install apps
The scammer asks you to install a screen-sharing app like AnyDesk, TeamViewer, or QuickSupport to 'help resolve the issue'. This gives them full access to your phone.
They already know some of your details
The scammer mentions your name, partial account number, or last transaction to build trust. This data is often obtained from data breaches and does not prove they are from your bank.
OTP arrives that you did not request
You receive an OTP without initiating any transaction. Someone is actively trying to access your account. Do NOT share this OTP and contact your bank immediately.
The Golden Rule
No legitimate organization will EVER ask for your OTP. Not your bank, not RBI, not police, not delivery companies.
If someone asks for your OTP — by call, SMS, WhatsApp, or email — it is a scam. No exceptions. Hang up. Delete the message. Report the number.
What to Do If You Receive an OTP Scam Attempt
Follow these steps whether you have already shared the OTP or caught the scam in time.
Hang up immediately
If someone calls asking for your OTP, disconnect. Do not engage, argue, or try to verify their identity on the same call.
Do not click any links
If you received a suspicious SMS or message with a link, do not click it. Delete the message.
Call your bank directly
Use the number printed on the back of your debit/credit card or your bank's official website. Never use a number provided in the suspicious message.
Report the scam
Call the Cyber Crime Helpline at 1930, file a complaint at cybercrime.gov.in, and report the number to your telecom provider.
Change your passwords
If you suspect any compromise, immediately change your net banking and UPI passwords. Enable two-factor authentication where possible.

Frequently Asked Questions About OTP Fraud
Can bank employees ask for OTP?
No. No bank employee, manager, or customer care executive will ever ask for your OTP. Banks explicitly state this in every SMS that contains an OTP. If someone claiming to be from your bank asks for an OTP, it is 100% a scam. Hang up immediately and call your bank's official helpline to report the incident.
What happens if I share my OTP with a scammer?
Once a scammer has your OTP, they can complete transactions you did not authorize — transferring money from your bank account, making purchases, or even linking your account to their device. The damage happens within seconds. If you have already shared an OTP, immediately call your bank to freeze your account, change all passwords, and file a complaint on the Cyber Crime portal (cybercrime.gov.in) and the 1930 helpline.
Can scammers use OTP to empty my bank account?
Yes. If a scammer has your bank login credentials (often obtained through phishing) and you share the OTP, they can authorize large transfers, change your registered mobile number, or even add a new beneficiary. In many reported cases, victims have lost their entire savings within minutes. OTPs are the last line of defense for your account — never share them.
How to report OTP fraud?
Report OTP fraud immediately through these channels: (1) Call the National Cyber Crime Helpline at 1930. (2) File an online complaint at cybercrime.gov.in. (3) Contact your bank's fraud department to freeze the compromised account. (4) File an FIR at your local police station. (5) Report the scammer's phone number to your telecom provider. Time is critical — the sooner you report, the higher the chances of recovering your money.
Is it safe to share OTP with delivery agents?
Only share the delivery OTP that was specifically generated for confirming package delivery — and only with the delivery person standing in front of you with your package. Never share any OTP over a phone call or text message, even if someone claims to be a delivery agent. If a delivery company contacts you asking for an OTP to 'reschedule' or 'confirm' a delivery remotely, it is a scam. Legitimate delivery rescheduling is done through the app or website, never through OTP sharing.
