Kotak Mahindra Bank, among India's foremost private banks, is known for offering attractive interest rates on savings accounts. Recently, it expanded by acquiring ING Vysya Bank.

To access online banking services with Kotak, you require your CRN Number, also termed as Customer ID or Customer Relationship Number.

Here’s how to locate your CRN Number for Kotak Mahindra Bank:

1. Via Credit/Debit Card: Refer to the bank documents and welcome kit. Your CRN Number, typically an 8-digit number, is placed below your name on your card. If you were previously with ING Vysya Bank, the process to find your customer ID remains the same.
2. Via SMS: Without your card, send an SMS with 'CRN' to 9971056767. Your CRN Number will be sent to your registered mobile number. If the registered number isn't available, use the welcome kit for guidance.
3. Online for Migrated Customers: For former ING Vysya clients, visit this link and:
• Retail Banking Customers: Input your former customer ID and captcha to receive a new CRN.
• Business Banking Customers: Provide your previous corporate ID, customer ID, and captcha to get a new CRN.

Your CRN Number is essential for using Kotak net banking and accessing the Kotak 811 account, as well as for completing various bank applications.
