Quick answer: How to block a lost debit card and UPI in India

If you notice an unauthorized transaction, call the national cybercrime helpline at 1930 immediately.

If you lost your phone, call your telecom provider to block your SIM card first so no one can receive your OTPs.

You can then use the NPCI MyUPI Safety Switch or call your bank's official toll-free customer care number to block your UPI ID and bank cards.

What you need before you start

Gather these details before making any calls to save time during an emergency.

An alternate phone to call the helplines.
Your bank account number or the last four digits of your lost debit or credit card.
The registered mobile number linked to your bank account (you will need to know the number even if the SIM is lost).
The exact amount and time of the unauthorized transaction if money was stolen.

Steps to block your lost cards and UPI

Step 1: Call 1930 if money is missing

Dial 1930 to report financial fraud to the National Cyber Crime Reporting Portal. This alerts the banks to freeze the stolen funds. Do this first if you see a transaction you did not make. You can also report cyber fraud on 1930 and cybercrime.gov.in for further documentation.

Step 2: Block your SIM card if your phone is lost

Call your telecom operator from another number to block your SIM card. This stops thieves from resetting your UPI PIN using SMS OTPs.

Telecom Operator	Customer Care Number
Jio	199
Airtel	121
Vi	199

Step 3: Block UPI using the NPCI MyUPI Safety Switch

The National Payments Corporation of India introduced the MyUPI Safety Switch in 2026. You can use this feature through your bank's IVR or the NPCI portal. It instantly disables all UPI apps linked to your number, including Google Pay, PhonePe and Paytm.

Step 4: Block debit and credit cards via bank SMS or helpline

Send the RBI-mandated SMS code to your bank's official number to hotlist your debit and credit cards. You usually text a word like BLOCK followed by the last four digits of your card. You can also call the bank's emergency toll-free number to block the cards immediately.

How long it takes and what it costs

Blocking a debit card, credit card, or UPI ID is instant and completely free. Reporting a fraud on 1930 is also free.

Banks will charge a replacement fee when you request a new physical card. This usually costs between ₹100 and ₹300 plus 18 percent GST, depending on your bank and card type.

If it does not work

If your bank's helpline is unreachable, use their official net banking portal or mobile banking app from another device. You can block the cards under the card services section.

If the bank refuses to register your fraud complaint, email their Principal Nodal Officer.

If the bank does not resolve your unauthorized transaction complaint within 30 days, file a complaint to the RBI Ombudsman on cms.rbi.org.in (RBI).
