BOB Credit Card Mobile Number Change: Online & Branch

Key Takeaways

• The registered mobile number on your BOBCARD account is used for transaction OTPs, card delivery alerts, payment reminders, and fraud notifications. An incorrect or inaccessible registered number creates immediate security and operational risks.

• If you still have access to the old registered mobile number, the online method via the BOBCARD portal or BOB World app is the fastest route - the change is typically effective within 24 hours.

• If you have lost access to the old registered mobile number and cannot receive OTPs, the branch visit or customer care call method is required - these routes verify your identity through alternative means before processing the change.

• BOBCARD requires identity verification for mobile number changes to prevent fraudulent takeover of card accounts. OTP, security questions, or in-branch KYC document submission are the standard verification methods.

• After updating, test the new number by checking that transaction SMS alerts are delivered correctly on the next card transaction.

• 'bob credit card login' receives 27,100 monthly searches - confirming the BOBCARD portal is widely used, and portal-based mobile updates are accessible to most active cardholders.

Why Your Registered Mobile Number Matters So Much

Every security-critical function of your BOB credit card depends on your registered mobile number. When you shop online and the payment gateway requests an OTP, that OTP is sent to your registered mobile. If the number is outdated, OTP delivery fails and every online transaction is declined. When BOBCARD suspects a fraudulent transaction on your account and needs to send an alert, it goes to the registered number. When your card is dispatched by courier after a replacement request, the tracking communication goes to that number. When your payment due date approaches, the reminder SMS goes there.

The consequence of an outdated registered mobile number is total loss of real-time card visibility - no fraud alerts, no OTP functionality, no payment reminders. This is both a security risk (fraudulent transactions go undetected) and an operational problem (legitimate online transactions fail). Updating the number immediately when it changes is not optional - it is essential maintenance.

Method 1: Online via BOBCARD Portal (Old Number Still Accessible)

This is the fastest and most convenient method, available 24x7. You need access to the old registered mobile number for OTP verification.

Step-by-Step

1. 1 Visit bobcard.co.in and log in using your registered email and password. First-time portal users must register before logging in - the bob credit card login process requires your existing credentials.

1. 2 From the dashboard, navigate to 'Profile' or 'My Account' or 'Account Settings' - the label varies slightly by portal version.

1. 3 Select 'Contact Details' or 'Update Mobile Number'.

1. 4 The current registered mobile number is displayed (typically masked as XXXXXX1234 showing only the last 4 digits). Click 'Change' or 'Update'.

1. 5 Enter your new mobile number in the designated field. Re-enter to confirm.

1. 6 BOBCARD sends a verification OTP to your OLD registered mobile number. This step confirms that the request is being made by the genuine cardholder who has access to the currently registered number.

1. 7 Enter the OTP received on your old number.

1. 8 BOBCARD may send a second OTP to the NEW mobile number to confirm the new number is active and reachable. Enter this OTP when prompted.

1. 9 A confirmation message appears on screen and an SMS is sent to your new number confirming the update. The change typically takes effect within 1 to 4 hours.

NOTE: If Step 8 (OTP to new number) fails because the new number is not yet active on your SIM, wait for the SIM to be fully activated and retry. OTP delivery to a new SIM can take 1 to 4 hours after SIM activation.

Method 2: Via BOB World App (Old Number Still Accessible)

The BOB World app provides the same mobile update functionality as the portal, accessible from your smartphone. This method is suitable for Bank of Baroda account holders who manage their credit card through the app.

Step-by-Step

1. 1 Open the BOB World app and log in with your MPIN or biometric authentication.

1. 2 Navigate to 'Profile' or 'Account Settings' from the app home screen or the menu icon.

1. 3 Select 'Update Contact Details' or 'Change Mobile Number'.

1. 4 Enter your new mobile number and confirm.

1. 5 Verify with OTP sent to your old registered number.

1. 6 Confirm with OTP sent to the new number if prompted.

1. 7 The app displays a success message. You receive an SMS on your new number confirming the change.

Method 3: Customer Care Call (Old Number Not Accessible)

If you no longer have access to the old registered mobile number - the number has been deactivated, transferred, or lost - the online OTP verification route is unavailable. The customer care call method uses alternative identity verification to process the change.

Step-by-Step

1. 1 Call BOBCARD customer care on 1800 2665 100 (toll-free, 24x7). Have your BOB credit card, PAN card, and Aadhaar within reach before calling.

1. 2 Navigate the IVR to 'Credit Card Services' and then 'Account Update' or press 0 to reach an agent directly.

1. 3 Inform the agent: 'I want to update the registered mobile number on my BOBCARD credit card. I no longer have access to the currently registered number.'

1. 4 The agent will verify your identity through alternate means since OTP to the old number is not available. Typical verification includes: full name as per BOBCARD account, date of birth, last 4 digits of your credit card, last transaction amount and merchant (if recalled), and PAN number.

1. 5 Once identity is verified, provide your new mobile number to the agent.

1. 6 The agent raises a service request for the mobile number change. A reference number is provided.

1. 7 BOBCARD may require a written request or additional document verification depending on the agent's assessment. In some cases, they may direct you to the branch for in-person KYC verification.

1. 8 Processing time via customer care: 24 to 72 hours after identity verification is completed.

TIP: Call from the new mobile number you want to register. While BOBCARD verifies identity through other means, calling from the new number helps the agent cross-verify and may expedite the request.

Method 4: Branch Visit (Most Reliable for Inaccessible Old Number)

If you cannot receive OTPs on the old number and the customer care route requires additional documentation, visiting a Bank of Baroda branch in person is the most reliable path. Branch staff can process the mobile number change after physical KYC verification.

Documents to Carry to the Branch

What Happens at the Branch

1. 1 Visit any Bank of Baroda branch - you do not need to go to the branch where the card was issued.

1. 2 Approach the customer service desk and inform them you need to update your BOBCARD credit card registered mobile number.

1. 3 Submit your written request letter and original identity documents.

1. 4 The branch representative verifies your identity against their records and BOBCARD's system.

1. 5 A service request is raised in the system. You receive an acknowledgement reference number.

1. 6 The change is processed within 2 to 5 working days. A confirmation SMS is sent to your new number once active.

Special Scenario: New SIM, Same Number

If you have obtained a new SIM card but retained the same mobile number (mobile number portability or replacement SIM for the same number), no BOBCARD update is required. Your registered number is the phone number itself, not the physical SIM. A new SIM carrying the same number continues to receive OTPs and alerts without any BOBCARD action. Simply ensure the new SIM is activated and receiving SMS messages before attempting any online transactions that require OTP.

Special Scenario: Number Transferred to Someone Else

If your old registered number has been deactivated and re-issued by the telecom operator to a different person, this is an urgent security situation. The new subscriber of your old number would receive OTPs intended for your BOBCARD transactions. In this case: call BOBCARD customer care on 1800 2665 100 immediately, report the situation, and request both an emergency mobile number update and a temporary block on all OTP-required transactions until the new number is verified. This situation requires the customer care or branch route since you cannot receive OTPs on the number that someone else now holds.

After Updating: Verification Checklist

Once BOBCARD confirms the mobile number change, run through this checklist to ensure everything is working correctly:

• Make a small online transaction (Rs 1 on any UPI app or Rs 1 on any e-commerce platform) to trigger an OTP. Confirm the OTP arrives on your new number.

• Check that transaction SMS alerts are arriving on the new number - make a small in-store card transaction and verify the SMS comes through within 30 seconds.

• Log in to the BOBCARD portal at bobcard.co.in and confirm the new number is displayed in your profile section.

• Update your mobile number on the BOB World app if you use it - in some cases portal and app profiles sync automatically, but verify.

• If you have auto-pay or NACH mandates set up, the mandate is linked to your bank account, not your mobile number - these are unaffected by the mobile number change.
