How to Block/Unblock Kotak Mahindra Bank Debit Card online

The prominent growth and interest in the cybersecurity industry are closely related to the rise of online banking services. Digitization provides improved security, better delivery on bank facilities, and benefits the environment.

Debit cards revolutionized how we interact with our bank accounts. Withdrawing and depositing cash takes minutes and saves us from a trip to the nearest branch every time we need pocket money.

Despite being equipped with improved authentication procedures and online systems, we are susceptible to financial fraud and cybercrimes. We may even misplace our card. It is critical to block our debit cards in case our bank accounts are vulnerable. Moreover, treat it as a preventive measure to secure our money from falling into the wrong hands.

Kotak Mahindra Bank offers both online and offline procedures to block and unblock debit cards. Now, customers may not have easy access to a branch immediately or have the time to wait until the next day for actions.

Alternate methods using a personal computer or cell phone ensure the process takes place directly. You require an internet connection on any device or a mobile phone with the registered number in it.

With a Kotak Bank debit card, there are multiple ways to block your card permanently or temporarily.

  • Log in to the 811 App using your six-digit login PIN.
