Overall, there are multiple methods to unblock ATM cards. Nevertheless, if the bank temporarily blocks your card, you must request them to unblock it. However, if your ATM card is expired or deactivated, you cannot unblock it to start using the card again. In such scenarios, you must apply for a new ATM card. 

Reasons for Blocking an ATM Card

Your ATM card may be blocked automatically or manually, depending on the situation. Here are some common reasons:

  • Incorrect PIN Attempts: Entering the wrong PIN three times in a row leads to automatic blocking for 24 hours as a security measure.
  • Suspicious Transactions: Banks may block your card if they detect unusual or fraudulent activity.
  • Card Misplacement or Theft: If you report your card lost or stolen, it is blocked to prevent misuse.
  • Inactive Card: If you haven’t used your ATM card for a long time, the bank may deactivate it as a precaution.
  • KYC Issues or Account Freeze: Non-compliance with KYC guidelines or account-related issues may result in card deactivation.
  • Manual Request by Customer: You may request the bank to block the card due to personal reasons, like limiting spending or temporarily disabling access.

Depending on your bank’s services, you can unblock ATM card through net banking, SMS, customer care, or by visiting the branch. Always identify the reason for the block first and then follow the right method to unblock ATM card. You must apply for a new card instead of trying to reactivate it if the card is permanently blocked or expired.
