Credit Limit Increase Call Scam
A caller offers to raise your credit card limit and asks for an OTP or card details. The OTP approves a payment from your card instead.
Someone who sounds like a bank executive calls to say your credit card limit can be raised for free because of your good payment record. They need a few details and an OTP to process it. It sounds like good news, which is why people go along with it. The OTP is not for a limit increase. It is for a purchase being made on your card.
How the scam works
The scammer buys or finds lists of card holders and calls with polite scripts. They may know the name of your bank and the last four digits of the card, which they use to sound genuine. They explain that the offer is only for selected customers, which flatters you, and that it will expire at the end of the day.
They then ask for card number, expiry date and CVV 'to check eligibility', and say a verification code will arrive. In the background they use those details to make an online purchase, such as vouchers or a wallet top-up, which triggers an OTP to your phone. When you read it out, you approve the transaction.
The amount taken may be close to your whole available limit. Some scammers also use the card details later for smaller repeated purchases that go unnoticed. They gain money or goods bought with your card, while you are left with a bill and a call to the bank explaining that you shared the OTP yourself.
An example of what you may see
Example only: 'Good afternoon sir, I am calling from the card department. Because of your excellent record we have raised your limit from Rs 1 lakh to Rs 3 lakh. To activate it I need your card number, expiry and CVV. You will get a code on your phone. Please read it out so I can finalise it before the offer ends today.' He never lets you hang up to call the bank back, and says the offer will vanish if you do.

Questions people ask
Does a bank ask for an OTP to raise a credit limit?
No. An OTP is for approving a transaction or login. A genuine bank does not need you to read it out to a caller. Any offer on your card can be checked in the bank's official app or through the number on your card.
How did the caller know my card's last digits?
Such details can come from leaks, past frauds or earlier calls. Knowing a few details does not prove the caller is from the bank. Hang up and call the bank yourself on the number printed on your card.
What if I already read out the OTP?
Call your bank straight away to block the card and report the transaction. Then call 1930 and file a report on the cyber crime portal. Quick reporting helps the bank try to stop the money.
