“Ma’am, I sent money by mistake to your number. Please send it back. It’s for my mother’s operation.”
That was the voice on Pooja’s phone at 9:40 on a Tuesday night.
Pooja, my cousin’s friend, runs a small tiffin service in Pune. Every day, strangers pay her on UPI. So when an SMS said “₹4,999 credited to your account”, she didn’t even blink.
Then the call came. The man was almost crying. He’d already sent her a screenshot on WhatsApp. He gave her a different UPI ID and said, “Please send to my brother’s ID, my account is blocked.”
Pooja’s thumb was on the pay button. She didn’t press it. Not that night.
Was the man lying? Was the ₹4,999 even real? And what happened to Pooja’s bank account two weeks later? I’ll tell you at the end. First, your question.
A stranger sent money by mistake to your UPI. Is it really a mistake?
Short answer: sometimes yes, often no. Don’t decide on the phone.
Honest mistakes happen every day. One wrong digit, or the wrong “Pooja” in contacts. My own cousin once paid his electricity bill amount to an old colleague’s number by mistake. It happens.
When a stranger says they sent money by mistake, it’s usually one of these three:
- A real mistake. Real money, from a real person who typed the wrong number.
- A fake credit. No money came at all. Only a fake SMS or a fake screenshot.
- Real money, but stolen. The money came from a fraud victim somewhere else. The scammer wants you to pass it on.
All three come with a sad story and a hurry. That hurry is the first clue. A real person who sent money by mistake is worried, but they don’t need it back in five minutes. A scammer does.
How do you check if the money really reached your account?
Open your bank app or passbook yourself. Never trust an SMS or screenshot someone sends you.
This is the first thing Pooja did right. She didn’t look at WhatsApp. She opened her bank’s own app and checked the statement.
Why? Making a fake payment screenshot takes about a minute today. AI image tools can make a “payment successful” screen that looks perfect, with a logo, a fake transaction ID and the right time.
Fake bank SMS are easy too. Real bank SMS come from a short sender name with the bank’s code. A “Rs 10,000 credited” message from a normal 10-digit number is a red flag.
I got one of these myself last year. “Dear customer, INR 10,000 credited to your A/c XX4521.” My account doesn’t even end in 4521. It came from a +91 number. I deleted it and blocked the number.
Before you believe anyone:
- Check your balance and statement in your bank’s official app or net banking.
- Don’t use any link the caller sends you to “check”.
If the money isn’t in your statement, you’re done. Block the number. It was a fake credit.
If the money is there, slow down even more. Real money doesn’t mean an honest sender.
Stranger sent money by mistake? Why you shouldn’t send it back yourself
Your gut says, “It’s not my money. Let me just return it and be done.” That’s exactly what scammers count on.
Problem 1: you might send it to the wrong person. Pooja’s caller asked her to pay a different UPI ID. “My brother’s.” Why would a real person want it back in some other account? That alone should stop you.
Problem 2: the money may be stolen. Here’s how this UPI scam works. A fraudster cheats someone in, say, Kolkata, maybe with a fake job like the task scams in my guide on earning money from home. That victim’s money is sent to your account. Then the fraudster calls you with a sob story and asks you to “return” it to his account. Now you’ve moved stolen money for him. Your account becomes a link in the chain.
Police call these mule accounts. Accounts that pass fraud money from one place to another.
Problem 3: you can lose twice. When the real victim complains, police trace the money to your account. Your bank may freeze it. And the ₹4,999 you “returned”? That’s gone to the scammer. You can’t show it went back to the real owner.
If you want to know more about how these frauds move, my guide on UPI and online fraud in India covers the common tricks in detail.
Can a UPI scam take money when you only check your balance?
No. Checking your balance with your PIN doesn’t approve any payment.
You may have seen WhatsApp forwards about the “jumped deposit” scam: a stranger sends ₹5,000, you check your balance with your PIN, and a bigger withdrawal goes through.
In January 2025, NPCI, the body that runs UPI, put out a clarification on the jumped deposit scam. It said it hadn’t seen such cases on UPI. A balance check is its own separate step, and it doesn’t approve any other request.
So checking your balance is fine. The real trap is different. Scammers send a collect request or a QR code and say, “Enter your PIN to receive the refund.” Or “enter PIN to accept my money.”
You never need your UPI PIN to receive money. Ever.
If any screen asks for your PIN, you’re paying, not receiving. NPCI’s own UPI safety tips say the same thing.
My colleague’s father learnt this the hard way while selling an old fridge online. The “buyer” sent a QR code “to pay him”. He scanned it, typed his PIN, and ₹8,000 left his account instead of coming in. He told us later, “I thought PIN means receive.” It doesn’t.
Genuine mistake or UPI scam: how can you tell the difference?
If most of your answers fall in the right column, treat it as a scam.
| What you notice | Usually a real mistake | Usually a scam |
|---|---|---|
| Money in your bank statement | Yes, clearly shown | Only in an SMS or screenshot |
| Where they want it back | Same account it came from | A new UPI ID, “brother’s” account |
| How fast | Fine to go through the bank | “Right now, please, emergency” |
| What they ask you to do | Nothing, or call their bank | Scan a QR, approve a request, share OTP |
| When you say “let’s do it via the bank” | “OK, thank you” | Angry, crying or threatening |
That last row is the best test I know. Say calmly, “Please raise a complaint with your bank. I’ll return it through my bank.” A real person agrees. A scammer shouts or vanishes.
Someone sent money by mistake: what’s the right way to return it?
Through the banks. Not through your phone, and not to any new account.
First, the legal bit, in simple words. Money credited by mistake isn’t yours to keep. Section 72 of the Indian Contract Act says a person who gets money by mistake must return it. You can read the Act on India Code, the government’s site for central laws. So spending it isn’t an option either.
Here’s the safe route:
- Don’t touch the money. Don’t spend it, don’t move it to another account.
- Tell the caller to complain to their own bank or UPI app. If the person is real, their bank will raise a request with your bank.
- Tell your bank yourself, in writing. Visit the branch or email customer care. Say: “An unknown credit of ₹X came on this date from this UPI ID. I didn’t expect it. Please return it to the sender through the proper process.” Keep a copy.
- Give consent only to your bank. When your bank contacts you, agree to the reversal. The money goes back to the same account it came from.
- Keep everything. Screenshots of the call log, WhatsApp chats and your bank complaint number.
Yes, it takes a few days. The slow way protects you.
Curious how NEFT, IMPS and UPI move money behind the scenes? See my post on how to transfer money between banks.
And if you sent money by mistake to a stranger? Same route, other side. Complain in your app and to your bank the same day. My cousin did it the bank way and got his money back in about a week.
Can AI help you spot a fake payment message?
Yes, as a second opinion. Not as a judge.
That night, Pooja copied the SMS and the WhatsApp message (not the screenshot with her account details) into ChatGPT and asked if it looked real.
The AI pointed out three things she’d missed. The SMS came from a mobile number, not a bank sender name. The “transaction ID” in the screenshot had a strange format. And the caller wanted the refund in a different UPI ID.
Useful. But the AI couldn’t see her bank account or say if the money was real. Only her bank app could.
Scammers use AI too, for fake screenshots, fake SMS and even fake voices of your family members. So AI on your side is fair. Just don’t let it have the final word.
Here’s a prompt you can copy into ChatGPT, Gemini or any AI app:
Someone says they sent money by mistake to my UPI and wants it back. Below is the SMS and the chat they sent me. I have removed my account number and name. Please list every sign that this could be a UPI scam, and every sign that it could be a real mistake. Then tell me the safest step-by-step way to handle it through my bank. Don’t tell me to send money to anyone directly.
[Paste the SMS and chat here]
See what’s missing from that prompt? Your full account number, PAN, Aadhaar, card details or OTP. Never paste those into any AI app. I’ve written more about using AI safely with money in my guide on using AI to plan your monthly budget.
If you like reading about money in simple Indian language, Let’s Talk Money by Monika Halan is the book I keep recommending. It makes you calmer and smarter with money in general.
What if you already sent the money back to a scammer?
Act in the first hour. Call 1930.
Don’t sit and feel stupid. Speed matters more than shame.
- Call 1930. It’s the national cyber fraud helpline. Faster reports mean a better chance to hold the money.
- Report online on the National Cyber Crime Reporting Portal. Note down your complaint number.
- Call your bank and block UPI for a while if you shared anything like a PIN or OTP.
- Report the caller’s number on Chakshu on Sanchar Saathi, the government’s page for suspected fraud calls and messages.
The portal is run by the Home Ministry’s Indian Cyber Crime Coordination Centre, which works with banks to hold fraud money fast.
One honest thing you should know. RBI has a rule on limiting customer liability in unauthorised electronic transactions. If someone else misuses your account and you report it within three working days, your loss can be zero. But when you sent the money yourself with your own PIN, banks may not treat it as “unauthorised”. So prevention really is your best protection.
If your bank doesn’t reply in 30 days, complain free to the RBI Ombudsman on the RBI complaint portal.
And keep your bank’s helpline number written somewhere outside your phone. If you’re stuck on a call with a scammer, you’ll want it. A small pocket phone number diary by the door works better than you’d think.
Can money credited by mistake get your account frozen as a mule account?
Yes, if that money was stolen. That’s why you report it early.
When a fraud victim complains, police follow the money. Every account it touched can be put on hold as a possible mule account, including yours. Sometimes only that amount, sometimes the whole account.
Here your early written complaint becomes gold. It shows you didn’t spend it or pass it on.
If your account is frozen:
- Ask your bank in writing which police station or cyber cell asked for the freeze.
- Contact that cyber cell with your bank complaint, chats and statement.
- If it drags on, talk to a lawyer.
This is also why your emergency fund should sit in more than one place. Rent doesn’t wait for a frozen account. My post on why you need an emergency fund and where to keep it explains how to split it.
How can you keep your UPI safe from this kind of scam?
A few small habits stop most of these tricks:
- Use a separate small account for UPI. Keep your main savings in another account that isn’t on any app.
- Never enter your PIN to “receive”. Receiving never needs it.
- Return money only through your bank, and only to the account it came from.
- Check which mobile numbers are linked to your name on Sanchar Saathi. Old numbers are a door for fraud.
- Learn the common tricks from RBI Kehta Hai, RBI’s own awareness site.
Another option some people like: pay online with a RuPay credit card on UPI instead of your savings account. Your savings aren’t touched directly, and you can dispute a charge before paying the bill. Something like the HDFC RuPay credit card works on UPI apps. But only if you pay the full bill every month. My guide on using a credit card without paying interest shows how.
For bigger online shopping, a card with cashback, like the SBI Cashback card, gives some money back too. If you’ve never had a card, read my guide to choosing your first credit card in India before you apply.
When I started Arocol, I got a ₹1 UPI payment from a stranger with the note “hi madam pls check”. I didn’t reply. Two days later came a collect request for ₹2,000 from the same ID. Tiny money first, big request later. Festive season brings fake “refund” calls too, as I wrote in my festive sale shopping tips.
So did Pooja refund the ₹4,999?
Remember her thumb on the pay button?
She opened her bank app first. The ₹4,999 was real. It was right there in her statement.
But the “brother’s UPI ID” kept bothering her. So she sent one message: “I’ll return it through my bank. Please complain to your bank.” Then she pasted the chat into ChatGPT, which flagged the different UPI ID too.
The man called four more times. Then an angry voice note, shouting at her. Her husband heard it from the kitchen and laughed, “Pooja, what is this behavior? Who shouts at you at 11 pm?”
She showed him the chat. He stopped laughing. Then the man went silent.
Next morning, Pooja went to her branch and gave a written complaint about money credited by mistake.
Two weeks later, her account showed “debit freeze” on exactly ₹4,999. Her heart sank.
Then the bank explained. A man in Odisha had been cheated in a fake loan offer. Part of his money went into Pooja’s account. The cyber cell traced it and asked the bank to hold it.
Because Pooja had complained first, the bank already had her letter on file. The amount went back to the real victim. Her account was unfrozen in a few days, and her tiffin business never stopped.
Now think about the other ending. If she’d sent ₹4,999 to the “brother’s” UPI ID that night, the scammer would have it, the victim wouldn’t, and Pooja’s account would still be frozen. With her own ₹4,999 gone too.
So when a stranger says they sent money by mistake, remember Pooja. Check your bank app. Don’t pay any new UPI ID. Return it only through your bank. Slow is safe.
