Accidental Money Credit Callback Scam in India 2026: UPI Refund Fraud on the Rise

Fraudsters in India are exploiting the popular UPI payment system with a new twist called the Accidental Money Credit Callback Scam, causing serious financial losses for unsuspecting victims.

What Is the Accidental Money Credit Callback Scam?

The Accidental Money Credit Callback Scam is a growing cyber fraud targeting Indian UPI users. It begins with fraudsters pretending to refund an “extra” or “accidentally credited” amount to your bank account via UPI. They then contact the victim, pretending to be bank representatives or customer support agents, requesting a callback or urgent confirmation to reverse this “wrong credit.”

This scam exploits the victim’s confusion and goodwill — the idea of getting free money makes many people respond quickly without verifying the details. It mainly targets everyday UPI users who may not be aware of how digital payments and UPI reversals work. The scam has seen a rise across India in 2025 and 2026, with several cases reported to police and complaints lodged with cybercrime cells.

Indian cybersecurity agencies like CERT-In and the Interpol-coordinated Indian Cyber Crime Coordination Centre (I4C) have flagged this scam pattern. The Reserve Bank of India (RBI) has also warned consumers to be cautious when receiving unsolicited refund messages over WhatsApp or SMS.

How This Scam Works — Step by Step

1. Fake Refund Notification: You receive an unsolicited message on WhatsApp or SMS claiming that a certain amount (e.g., ₹5,500) has been accidentally credited to your bank account or UPI ID.

2. Fraudster’s Call: Shortly after, the caller pretends to be from your bank or a payment service, asking you to call back a number for verification or to reverse this accidental payment.

3. Social Engineering: When you dial back (which often connects to the fraudster), they create urgency and confusion, saying the money must be returned immediately to avoid account freezing or legal trouble.

4. Request to Transfer Money: The caller then tricks you into initiating a UPI payment (possibly to a different UPI ID like us**@bank) to “refund” the money, or they may ask you to share UPI PIN or bank OTP under the pretext of verifying or reversing the transaction.

5. Financial Loss: Once you share sensitive details or transfer funds, the fraudster steals the money. Victims often realize too late that no money was ever truly credited or refunded.

Real Warning Signs to Watch For

• Unexpected messages about “accidental” refunds to your account without prior transactions.
• Urgent calls demanding immediate callback or payment to “reverse” a transaction.
• Requests for sharing your UPI PIN, OTP, or bank passwords over phone or WhatsApp.
• Pressure tactics warning of account freezing, legal action, or government involvement.
• Calls from numbers that don’t match your official bank’s customer service.
• Mismatched or unfamiliar UPI IDs when asked to transfer “refund” money.
• Poor grammar or unusual language in refund messages or calls.

What Happens to Victims

Victims of this scam often face significant financial loss, as the stolen funds are transferred out quickly via UPI, making recovery difficult. Unlike bank account hacks, UPI transactions cannot be easily reversed once completed. Emotional distress follows — fear, embarrassment, and loss of trust in digital payments, especially among older or less tech-savvy users.

In some cases, victims also experience secondary fraud like SIM swap attacks or Aadhaar-related identity theft, as fraudsters use gathered personal information to further exploit accounts. The complexity of India’s UPI ecosystem and multiple wallets makes it challenging but essential to be vigilant.

What RBI and CERT-In Say

The Reserve Bank of India, in line with its ongoing guidance, advises never to share UPI PIN or OTP with anyone, including calls claiming to be from banks. RBI’s customer protection rules state that banks are not liable for losses resulting from user negligence such as sharing confidential information.

CERT-In recommends reporting such incidents promptly to cybercrime authorities and emphasizes vigilance against social engineering attacks. The central government's 1930 cybercrime helpline is available for immediate assistance.

The Indian Cyber Crime Coordination Centre (I4C) encourages users to verify unexpected refund texts by directly contacting their bank or using official UPI app channels instead of responding to unsolicited calls or messages.

How to Protect Yourself

1. Ignore unsolicited refund messages claiming accidental credits; verify independently via your banking app.
2. Never share your UPI PIN, OTP, or bank passwords with anyone over phone or chat.
3. Do not call back unknown numbers asking for transaction reversal or refund confirmations.
4. Verify bank calls by calling official customer care numbers listed on bank websites or UPI apps.
5. Use official UPI apps and check transaction history before acting on refund claims.
6. Report suspicious messages and calls immediately to your bank and cybercrime helpline 1930.
7. Regularly update your phone’s security settings and avoid installing untrusted apps.

What to Do If You've Been Targeted

• Immediately block the caller and do not engage further.
• Contact your bank’s official customer care to block or freeze your UPI ID and linked accounts.
• Lodge a complaint with the 1930 cybercrime helpline or file a complaint at cybercrime.gov.in.
• Report the fraudulent phone number and UPI ID to your bank and ask for transaction trace or dispute support.
• Change your UPI PIN and bank account passwords at once.
• Inform your mobile operator if you suspect a SIM swap or related fraud.
• Keep all messages, call recordings, and transaction screenshots as evidence if you file a police complaint.
