What to Do If Credit Card Is Blocked for Suspicious Transaction

1. Call customer care immediately (numbers above for your bank)
2. Bank will ask you to verify recent transactions (they'll read them out, you confirm valid/invalid)
3. For valid transactions you don't recognize → report as fraud
4. For all transactions are valid → bank unblocks after you confirm
5. New card issued if old card is compromised

Credit Card Blocked for Non-Payment of Bill

If your card is blocked because the bill is overdue:

1. Pay the minimum amount due immediately via net banking / UPI
2. Credit card usually reactivates within 2–4 hours after payment reflects
3. To reactivate instantly: Call customer care after paying → they can manual-trigger reactivation
4. Pay full outstanding amount to restore complete credit limit

Enable International Transactions

If your credit card is blocked for international purchases only:

Via App (All Banks): Bank App → Cards → Credit Cards → Card Controls → International Transactions → Enable

Timeline: Instant via app. Useful before international travel or international online purchases.

Security tip: Disable international transactions when not travelling abroad to prevent fraudulent overseas charges.

Credit Card Expiry — Get Replacement

1. Banks typically send replacement card 30–45 days before expiry to registered address
2. If not received: Call customer care or bank app → "Request Replacement Card"
3. Card delivered in 7–10 working days
4. Auto-activate on first use (insert and enter PIN at ATM) or call bank

Frequently Asked Questions

How long does it take to unblock a credit card? Instant via app or net banking (if you blocked it yourself). Via customer care: 15–60 minutes. For bank-initiated security blocks: after verification, usually same day.

My credit card keeps getting blocked for suspicious transactions — why? You may have inconsistent spending patterns, international purchases, or large transactions that trigger the fraud detection algorithm. Call bank to whitelist your usual spending patterns or update your "transaction profile".

Can I unblock my credit card if my bill is due but I can't pay fully? Pay minimum amount due (shown on statement). This usually reactivates the card within 4 hours. The remaining balance continues to accrue interest though.

Does blocking a credit card affect my credit score? Blocking/unblocking does not affect your CIBIL score. However, having a blocked card for extended periods (especially if it's credit utilisation related) may have indirect effects. Pay bills on time to maintain a good score.

My credit card is physically damaged — how to get a new one? Call customer care and request a "damaged card replacement". Most banks issue a replacement within 7–10 working days. The card number may or may not change — depends on the bank and reason.
