Your registered mobile number is more than just a contact detail. It is the gateway to OTPs, transaction alerts and important banking notifications. If you have switched to a new number, updating it promptly is essential — missing OTPs or alerts can disrupt transactions and put your accounts at risk.
Fortunately, changing the mobile number linked to your bank account is straightforward and can be done through several official channels. You can update your number using your bank’s mobile app or net banking (typically verified via an OTP sent to your old number), at an ATM with your debit card and PIN, or by visiting a bank branch with valid ID and submitting a request. Use only verified bank channels and keep your old number active briefly to complete verification.
How to Change Mobile Number in Bank Account Online?
If you prefer convenience, changing your mobile number online is usually the quickest method. Most banks follow a similar sequence of steps.
Step 1: Log in to Internet or Mobile Banking
Open your bank’s official website or mobile app and log in with your credentials. If you are not registered for net banking, most banks provide an online registration process.
Step 2: Go to Profile or Settings
Navigate to sections labeled Profile, Settings or Personal Details where account contact information is stored.
Step 3: Select Mobile Number Update Option
Choose the option to update contact details or change your registered phone number.
Step 4: Identity Verification (Mandatory)
To protect your account from unauthorised access, banks require identity verification before approving a number change. Common verification methods include:
- An OTP sent to your existing registered mobile number
- Your internet banking password or PIN
- Debit card details or answers to security questions
This verification step ensures the change is authorised and complies with KYC and fraud-prevention rules.
Step 5: Enter Your New Mobile Number
Carefully enter the new number and double-check it to avoid errors.
Step 6: Confirm and Submit
Submit the request. You will usually receive a confirmation message, and once processed, OTPs and alerts will be sent to the updated number.
Bank Branch Visit: Offline Method (Step-by-Step)
If online options are not available, you can update your mobile number by visiting a branch. The typical process is:
- Visit your home branch or the nearest bank branch
- Request a mobile number update form
- Fill in your account details and the new mobile number
- Submit valid ID proof such as Aadhaar or PAN card
- The bank verifies your documents to meet KYC requirements
- Once approved, the mobile number update is processed
Alternate Ways to Update Your Mobile Number
Besides net banking and branch visits, some banks provide other options:
- ATM Update: Use your debit card, enter your PIN and select the option to update your mobile number.
- Customer Care: Some banks allow updates over phone banking after proper verification.
These alternatives can be useful if you are considering whether you can change your bank account mobile number online or through assisted channels.
Important Tips to Keep in Mind
- Always use official bank apps, websites, ATMs or branch services.
- Keep your old mobile number active until verification is complete.
- Carry valid ID proof like Aadhaar or PAN for offline requests.
- Mobile number updates are part of mandatory KYC compliance, so discrepancies may delay processing.
- Never share OTPs, PINs or passwords with anyone.
- Choose a secure and official method to update your contact details to protect your account.
Following these precautions will help ensure a smooth and secure mobile number update for your bank account.
