Frequently Asked Questions

How long does it take to unblock a debit card? Instant via app or net banking. Via customer care: 30 minutes to 4 hours. Via branch: same day.

Why does my debit card keep getting blocked? Most common reason: Wrong PIN entered 3 times. Other causes: suspicious transaction pattern, account-level freeze, or daily limit exceeded. Check your bank's SMS alerts for the specific reason.

If my account is frozen, will unblocking the debit card work? No — if the underlying account has a debit freeze, the card will remain non-functional even after unblocking. Fix the account block first (KYC update, contact customer care), then the card will automatically work.

Can I unblock my debit card without internet? Yes — call customer care (listed above for each bank). Many banks also allow SMS-based blocking/unblocking. Check your bank's SMS banking service list.

Does blocking a debit card affect account transactions? No — blocking your debit card only blocks card-based transactions (ATM, online, POS). NEFT, IMPS, UPI, cheque transactions still work unless the account itself is frozen.
