ATM card block application format
A good application is short and contains everything the branch needs to act without calling you back:
- Date and the branch address (“To, The Branch Manager…”).
- Subject line that states the request — block the card and issue a new one.
- Account number and the last four digits of the card. Never write the full card number, CVV or PIN.
- When and where it was lost or what is wrong with it.
- The reference number if you already blocked it by phone or app.
- A request to check for unauthorised transactions.
- Your signature as in bank records and registered mobile number.
The form above builds this for you. Switch between English letter and हिंदी पत्र — the same details fill both.

| Branch application | Submit the letter from this page | Same working day |
What RBI rules say about fraud on a lost card
RBI’s circular on Limiting Liability of Customers in Unauthorised Electronic Banking Transactions (6 July 2017) protects you if you act quickly. When the fault is neither yours nor the bank’s but elsewhere in the system, and you inform the bank within three working days of getting the transaction alert, your liability is zero. If you inform the bank within four to seven working days, your liability is limited to a capped amount. Once notified, the bank must credit the disputed amount (shadow reversal) within 10 working days. If the loss is due to your negligence — such as sharing your PIN or OTP — you bear the loss until you report it. So block the card and report every unknown transaction immediately.
Hinglish mein samjhiye
Card kho gaya ho to pehle bank ke customer care ya app se turant block kariye. Phir is page par details bhar ke application banaiye, print kar ke sign kariye aur branch me ID proof ke saath jama kariye. Agar koi anjaan transaction dikhe to 3 working days ke andar bank ko batana zaroori hai.
