Update Mobile Number for Your Credit Card

When your number is correct, you avoid blocked payments, failed logins, and missed alerts that can place your account at risk. You also complete checks faster because your bank sends quick confirmations to the right number. A small update protects your card, keeps your transactions smooth, and helps you stay in full control of your account at all times.

Keeping your registered mobile number updated is essential for uninterrupted access and enhanced security. Banks send one‑time passwords (OTPs), transaction alerts, and fraud warnings to your registered number. If your mobile number is outdated or inactive, you may miss critical notifications related to suspicious activity or declined transactions.

Updating the mobile number registered with your credit card also ensures timely delivery of monthly statements, credit limit alerts, and service updates from your card issuer. In many cases, OTP‑based authentication is mandatory for online payments and account changes. An updated number helps avoid service disruptions and allows you to manage your credit card securely and efficiently.

Before proceeding with changing your registered mobile number, keep the following ready:

• Your currently registered mobile number (for OTP verification, if active)

• The new mobile number you want to update

• Access to receive OTP or verification calls

• Valid photo ID and address proof (required for offline or branch‑based updates)

• Your credit card or customer identification details

• Having these ready can help ensure a smooth and faster update process.
   

Having these ready can help ensure a smooth and faster update process.
