After receiving a new Kotak Mahindra Bank debit card, you should make sure the card is active and generate its PIN before using it for regular transactions. Kotak provides several self-service options, so customers normally do not need to visit a branch just to activate a card or create a PIN.
Kotak debit card activation can be managed through Mobile Banking, Net Banking and SMS Banking. PIN generation or regeneration is available through the Kotak Mobile Banking app, Net Banking, an ATM, SMS and Kotak’s online Instant PIN Generation facility. Customers can also contact Kotak’s Customer Contact Centre for assistance.
One important difference is that Kotak debit cards generally use a 6-digit PIN, whereas many other Indian banks use a four-digit debit card PIN. Kotak’s current ATM PIN guidance specifically identifies its ATM/debit card PIN as a six-digit code.
Activation and PIN generation should also be treated as separate processes. Activating or unblocking the card makes it available for transactions, while PIN generation creates the security number required for ATM and PIN-authenticated card transactions.

What Do You Need to Activate a Kotak Debit Card?
Depending on the method selected, keep the following ready:
- Kotak Mahindra Bank debit card
- Mobile number registered with Kotak Bank
- CRN or Customer Relationship Number
- Debit card number
- Card expiry date
- CVV printed on the back of the card
- Access to Kotak Mobile Banking or Net Banking
- Registered mobile phone for receiving OTPs
Kotak states that PIN generation requires an active debit card. If the card has been temporarily blocked, it must first be unblocked before a new PIN can be generated. PIN regeneration is not available for a permanently blocked card.

What Should You Do After Generating the Kotak Debit Card PIN?
Once the PIN has been generated successfully, make a small ATM or merchant transaction to make sure the card and PIN are functioning correctly.
You should also:
- Check whether your debit card is active.
- Enable e-commerce transactions if you plan to shop online.
- Enable international usage only when required.
- Review ATM, POS and online transaction limits.
- Keep contactless transactions enabled only according to your needs.
- Never share your debit card PIN, CVV or OTP with anyone.
Avoid using easily guessed numbers such as your birth date or repetitive combinations as your PIN.
What If Kotak Debit Card PIN Generation Fails?
If PIN generation does not work, check the following:
- The debit card is active.
- The card has not been temporarily or permanently blocked.
- The card number, expiry date and CVV are correct.
- Your registered mobile number is active and able to receive OTPs.
- You are using the latest OTP received from Kotak.
- The correct debit card has been selected in Mobile Banking or Net Banking.
Kotak specifically states that a PIN can be generated only for an active card. A temporarily blocked card has to be unblocked first, while PIN regeneration is not available for permanently blocked cards.
If the problem continues, contact Kotak Mahindra Bank. The bank currently lists 1800 4100 as its toll-free Customer Contact Centre number for banking queries, complaints and assistance.
FAQs
1. Is the Kotak Mahindra Bank debit card PIN four digits or six digits?
Kotak’s current official ATM PIN guidance states that a Kotak debit card ATM PIN is a six-digit code, unlike the four-digit PIN commonly used by several other banks. Customers should therefore follow the PIN length displayed by Kotak while generating the PIN for their particular card.
2. Can I activate my Kotak debit card without visiting a branch?
Yes. Kotak allows debit-card activation or reactivation through Mobile Banking, Net Banking and SMS. From the registered mobile number, you can also send DCUNBLOCK followed by the last four digits of the debit card to 5676788 or 9971056767.
3. Can I generate a Kotak debit card PIN if I have forgotten the old PIN?
Yes. You can regenerate the PIN through Kotak Mobile Banking, Net Banking, the Instant PIN Generation facility or other supported channels. You normally do not need to remember the old PIN when using the PIN-regeneration service, provided the card and customer authentication are successfully verified.
4. Why is my Kotak debit card working at an ATM but not for international payments?
International usage may not be enabled. Kotak states that debit cards issued after September 30, 2020 do not have international payments enabled by default. You can turn international usage on through Mobile Banking, Net Banking or SMS and separately set ATM, POS and e-commerce international limits.
