Your mobile number is an important part of your DigiLocker account because it is used for login and OTP-based authentication. If you have changed your mobile number, lost your old SIM, or no longer have access to the number registered with DigiLocker, you may need to update the mobile number linked to your account.
DigiLocker provides a way to change the registered mobile number through your account profile. If you have lost access to your old DigiLocker mobile number but your current mobile number is linked with Aadhaar, the official DigiLocker FAQ provides an Aadhaar OTP-based login method that can be used to access the account and update the number.
The process is important to understand because creating a completely new DigiLocker account is usually not the right solution when your existing account already contains your documents.
Can You Change Your Mobile Number in DigiLocker?
Yes. DigiLocker allows users to update the mobile number associated with their account.
The official DigiLocker FAQ specifically provides instructions for users who have lost their DigiLocker-registered mobile number. They can log in using Aadhaar OTP, provided the new/current mobile number is registered with Aadhaar, and then update the mobile number from the profile section.
The basic process is:
- Open DigiLocker.
- Select Sign In.
- Use the Aadhaar OTP login option.
- Complete OTP verification on the Aadhaar-linked mobile number.
- Open your profile.
- Edit the mobile number.
- Enter your new mobile number.
- Verify the new number using OTP.
After successful verification, the new number becomes the mobile number associated with your DigiLocker account.
How to Change Mobile Number in DigiLocker
Step 1: Open DigiLocker
Go to the official DigiLocker website and select Sign In.
The current DigiLocker sign-in system primarily asks for the registered mobile number, while also providing an option to use Aadhaar or VID when facing problems.
If you still have access to your existing DigiLocker mobile number, the normal login route can be used.
If you have lost the old number, continue with the Aadhaar OTP method explained below.
Step 2: Enter Your Aadhaar Number and Security PIN
If you have lost access to the old mobile number, DigiLocker advises users to sign in using their Aadhaar number and security PIN.
Enter your Aadhaar number and security PIN and continue.
The official FAQ specifically provides this route for users who have lost their DigiLocker-registered mobile number.
Step 3: Select “Try Using Aadhaar OTP Instead”
At the bottom of the sign-in page, select:
Try using Aadhaar OTP instead!
This option allows DigiLocker to send an OTP to the mobile number currently registered with your Aadhaar.
The official DigiLocker instructions specifically mention this option for recovering access when the old DigiLocker mobile number has been lost.
Step 4: Enter the Aadhaar OTP
An OTP will be sent to the mobile number registered with your Aadhaar.
Enter the OTP and the CAPTCHA information requested on the screen.
Then submit the verification.
If the Aadhaar authentication is successful, you should be able to access your DigiLocker account.
Step 5: Open Your Profile
After successfully logging in, open your Profile section.
Look for the mobile number associated with your DigiLocker account.
The official DigiLocker FAQ says users can edit the mobile number by selecting the pencil/edit icon displayed next to the mobile number.
Step 6: Enter Your New Mobile Number
Enter the new mobile number that you want to associate with your DigiLocker account.
Check the number carefully before submitting it.
A mistake at this stage can cause the OTP to be sent to the wrong number.
Step 7: Verify the New Number
After submitting the new mobile number, DigiLocker sends an OTP to the new number.
Enter the OTP to complete verification.
Once the OTP is successfully verified, the mobile number associated with your DigiLocker account is updated.
What If I Lost My Old DigiLocker Mobile Number?
You do not necessarily need access to the old number to update it.
This is one of the most useful parts of DigiLocker’s official recovery process.
If your Aadhaar has a working registered mobile number, you can:
- Open DigiLocker.
- Select Sign In.
- Enter your Aadhaar number and security PIN.
- Choose Try using Aadhaar OTP instead!
- Receive the OTP on your Aadhaar-linked mobile number.
- Complete authentication.
- Open your DigiLocker profile.
- Edit the registered mobile number.
- Enter your new mobile number.
- Verify the new number using OTP.
DigiLocker officially provides this process for users who have lost their old registered mobile number.
This is generally better than creating another account because your existing DigiLocker account may already contain important issued documents.
What If My New Mobile Number Is Not Linked With Aadhaar?
The Aadhaar OTP recovery method depends on receiving the OTP on the mobile number registered with Aadhaar.
DigiLocker states that for Aadhaar-based linking, the mobile number must be linked with the Aadhaar number.
If your new number is not linked with Aadhaar, you may not be able to complete the Aadhaar OTP verification required for this recovery method.
In that situation, you may first need to update your mobile number with UIDAI through the applicable Aadhaar update process.
After the Aadhaar record is updated, you can try the DigiLocker recovery process again.
Can I Change DigiLocker Mobile Number Without Aadhaar?
The official DigiLocker instructions specifically describe the Aadhaar OTP route for users who have lost their registered DigiLocker mobile number.
If you still have access to the old registered number, the normal account login process may be sufficient to access your profile and update your mobile number.
However, if you have lost the old number and do not have access to an Aadhaar-linked mobile number, the official FAQ does not describe another equivalent self-service method for bypassing Aadhaar OTP verification.
For unresolved account problems, DigiLocker provides an official support system where users can raise and track queries.
What If I Forgot My DigiLocker Security PIN?
If you have lost the old mobile number and also forgotten your security PIN, DigiLocker provides a separate Aadhaar-based security PIN reset process.
The official instructions are:
- Open DigiLocker.
- Select Sign In.
- Click Forget Security PIN.
- Enter your Aadhaar number.
- Enter your date of birth as recorded with Aadhaar.
- Select Submit.
- Choose Try using Aadhaar OTP instead.
- Enter the OTP received on your Aadhaar-linked mobile number.
- Enter the CAPTCHA.
- Submit the verification.
- Set a new security PIN.
DigiLocker states that the new security PIN can then be used to access the account.
This can be particularly useful if both your old DigiLocker mobile number and your old security PIN are no longer available.
What If I Am Not Receiving the OTP?
There can be several reasons why an OTP does not arrive immediately.
DigiLocker states that OTPs are normally sent instantaneously, but temporary problems can occur with its servers or with SMS delivery through the mobile service provider.
If the OTP is delayed:
- Wait for a few minutes.
- Check that the mobile network is working.
- Make sure the number is correctly linked with Aadhaar.
- Request a fresh OTP if the previous one expires.
- Avoid repeatedly entering an old OTP.
DigiLocker’s FAQ states that an OTP is valid for 10 minutes.
What If DigiLocker Says Mobile Number Is Not Linked With Aadhaar?
This message means DigiLocker cannot confirm the required Aadhaar-mobile connection.
The official FAQ advises users to make sure that the mobile number is actually linked with Aadhaar when using Aadhaar-based DigiLocker services.
If you recently updated your Aadhaar mobile number, make sure the update has actually been completed before trying the DigiLocker process.
Can I Create a New DigiLocker Account With My New Number?
You may be able to create a DigiLocker account using a new mobile number, but this should not be your first option simply because you changed your phone number.
Your existing DigiLocker account may contain:
- Driving Licence
- Aadhaar
- Marksheet
- Certificates
- Other issued documents
- Uploaded documents
Creating another account can leave you with documents spread across different accounts.
DigiLocker also explains that an Aadhaar number can already be registered with an existing DigiLocker account. If you then attempt to link that Aadhaar with another account, you may receive an “Aadhaar already registered” error.
Therefore, if you already have an account, recovering and updating that account is usually the better approach.
What Does “Aadhaar Already Registered” Mean?
If you receive an “Aadhaar already registered” message while trying to link Aadhaar, DigiLocker explains that the Aadhaar number may already be associated with an existing DigiLocker account.
This can happen when a person creates a non-Aadhaar DigiLocker account and later tries to link the same Aadhaar to another account.
Instead of repeatedly creating accounts, try signing in to the existing DigiLocker account using Aadhaar.
This can help preserve access to documents already associated with the account.
Will My DigiLocker Documents Be Deleted After Changing Mobile Number?
Changing the registered mobile number is an account-profile update. It does not mean that you should lose the documents already associated with your existing DigiLocker account.
The important point is to update the existing account rather than creating a completely new account.
DigiLocker maintains issued documents separately from user-uploaded files. Issued documents are provided by integrated government departments and agencies, while uploaded documents are files added by the user.
Therefore, use the existing account whenever possible.
Can I Change the Mobile Number From the DigiLocker App?
DigiLocker provides services through its website and mobile application.
The exact position of profile and account-management options can change as the app interface is updated.
If the mobile-number editing option is difficult to find in the app, use the official DigiLocker website and follow the Aadhaar OTP recovery process described in the official FAQ.
The important part is to complete the change through your existing account rather than creating another account unnecessarily.
What If I Changed My Mobile Number in Aadhaar?
If your new mobile number has already been successfully updated with Aadhaar, it can be used for Aadhaar OTP authentication.
This can make account recovery easier if your old DigiLocker mobile number is no longer available.
DigiLocker specifically instructs users who have lost their old registered number to use Aadhaar OTP sent to their Aadhaar-linked mobile number and then update the DigiLocker profile.
If you have recently updated Aadhaar information, make sure the update has been completed before attempting the DigiLocker login.
What If My Aadhaar Mobile Number Is Also Lost?
This situation is more complicated.
The DigiLocker recovery process described in the official FAQ depends on receiving an OTP on the mobile number registered with Aadhaar.
If you no longer have access to that number either, you may first need to update your Aadhaar mobile number through the applicable UIDAI process.
Once you have access to the mobile number registered with Aadhaar, you can use the Aadhaar OTP route for DigiLocker account recovery.
For account problems that remain unresolved, DigiLocker provides a support portal for raising and tracking requests.
What If DigiLocker Mobile Number Update Is Not Working?
Before contacting support, check the following:
- Your Aadhaar number is correct.
- Your Aadhaar-linked mobile number is active.
- You can receive SMS on the Aadhaar-linked number.
- You are using the correct DigiLocker account.
- Your security PIN is correct.
- You are using the latest OTP.
- The OTP has not expired.
- Your new mobile number is entered correctly.
- Your internet connection is working.
DigiLocker notes that temporary technical problems can sometimes affect OTP generation, delivery or UIDAI-related authentication.
If the problem continues, you can raise a support request through the official DigiLocker helpdesk.
DigiLocker Mobile Number Change: Common Mistakes
Creating a New Account Immediately
A common mistake is creating a new DigiLocker account as soon as the old mobile number stops working.
If your existing account contains important documents, try recovering that account first.
Using the Wrong Aadhaar Mobile Number
The Aadhaar OTP will be sent to the mobile number currently registered with Aadhaar, not necessarily the old number that was previously connected to DigiLocker.
Entering an Expired OTP
DigiLocker states that OTPs are valid for 10 minutes. If the OTP has expired, request a new one.
Entering the New Number Incorrectly
Check the new mobile number carefully before submitting it.
A single incorrect digit can send the verification OTP somewhere else.
Trying to Link Aadhaar to Another Account
If Aadhaar is already associated with an existing DigiLocker account, trying to link it to another account can result in an Aadhaar already registered error.
Confusing Aadhaar Information With DigiLocker Profile Information
Some Aadhaar information displayed in DigiLocker comes directly from UIDAI. DigiLocker explains that this information cannot be edited directly within DigiLocker.
Changing your DigiLocker mobile number should therefore not be confused with changing the mobile number stored in your Aadhaar record.
Important Difference Between DigiLocker Mobile Number and Aadhaar Mobile Number
These two numbers can be related but should not be assumed to be the same in every situation.
DigiLocker mobile number is the mobile number associated with your DigiLocker account.
Aadhaar mobile number is the mobile number registered with your Aadhaar record.
When using Aadhaar OTP authentication, the OTP is sent to the mobile number registered with Aadhaar.
For users who have lost their DigiLocker-registered number, this distinction is particularly important because the Aadhaar-linked number can be used to regain access to the DigiLocker account.
Quick Checklist for Changing DigiLocker Mobile Number
Before starting the process, keep these things ready:
- Your Aadhaar number
- Security PIN, if available
- Mobile number registered with Aadhaar
- New mobile number
- Access to SMS on the Aadhaar-linked number
- Active internet connection
If the old DigiLocker number is lost, follow the Aadhaar OTP route instead of repeatedly trying to receive an OTP on the old number.
Frequently Asked Questions
Conclusion
Changing your mobile number in DigiLocker is possible, and the process is especially useful when you have lost access to your old registered number. The most important requirement in that situation is access to the mobile number registered with your Aadhaar, because DigiLocker provides an Aadhaar OTP route for recovering the existing account and updating the new number.
Avoid creating a new DigiLocker account just because your old mobile number is no longer active. Your existing account may already contain important issued documents, and trying to link the same Aadhaar to another account can create an Aadhaar already registered error.
If you are unable to complete the process even after checking your Aadhaar, OTP and account details, use the official DigiLocker support facility for further assistance.
