DigiLocker is a government-backed digital platform that allows Indian citizens to store and access their important documents in electronic form. It works as a secure digital wallet where users can keep documents such as Aadhaar card, PAN card, driving licence, voter ID, insurance policies, and educational certificates. These documents can be accessed anytime through the DigiLocker mobile app or website.

Since DigiLocker is directly connected to a user’s Aadhaar number, the registered mobile number plays a very important role. It is used for login verification, OTP authentication, and document access. If you change your phone number or no longer use the old one, it becomes necessary to update your mobile number in DigiLocker to avoid future login problems.

Fortunately, DigiLocker provides a simple and secure way to change your registered mobile number directly through the mobile application.

Why Updating Mobile Number in DigiLocker Is Important

Your mobile number is linked to:

• Login authentication
• OTP verification
• Aadhaar-based identity confirmation
• Secure access to stored documents

If your number becomes inactive or is lost, you may face difficulties accessing your account. Updating your mobile number ensures:

• Continuous access to digital documents
• Enhanced security
• Smooth verification process
• Protection from unauthorized access

This update is especially important for users who recently changed their SIM card or moved to a new network.

Things You Need Before Updating Your Number

Before starting the process, make sure:

• You have access to your DigiLocker account
• Your Aadhaar-linked mobile number is active
• You have your new mobile number ready
• Your DigiLocker app is updated to the latest version

You will receive OTPs during the verification process, so both old Aadhaar-linked and new mobile numbers must be accessible.

How to Change Mobile Number in DigiLocker App

Follow these easy steps to update your mobile number:

1. Open the DigiLocker app on your smartphone.
2. Log in using your username and 6-digit security PIN.
3. An OTP will be sent to your registered mobile number for login verification.
4. On the OTP screen, select the option “Update your mobile number.”
5. Enter the OTP received from UIDAI on your Aadhaar-linked mobile number.
6. Now type in your new mobile number.
7. DigiLocker will send a new OTP to the newly entered number.
8. Enter this OTP to confirm and complete the update process.

Once verified, a confirmation message will appear on your screen indicating that your mobile number has been successfully changed.

Security Measures During the Update Process

DigiLocker uses multiple levels of authentication to protect user accounts:

• OTP verification from UIDAI
• OTP confirmation on the new mobile number
• Secure login using PIN or biometric authentication

These measures ensure that only the rightful account holder can update personal information.

Common Issues and Solutions

Some users may face difficulties such as:

• Not receiving OTP
• Entering incorrect Aadhaar-linked number
• Network connectivity issues
• App not updated

To avoid these problems:

• Check your network connection
• Ensure Aadhaar-linked number is active
