Guide To Link Mobile Number To Aadhaar

How to link Aadhaar to mobile number: A guide

Aadhaar card is necessary to establish identity and avail social security schemes from the government. It is also necessary to file income tax returns (ITR) and investing in stocks and mutual funds and to open and maintain bank accounts.

Another important rule is that all mobile phone users have to link their mobile numbers with the Aadhaar.

Linking Aadhaar with Mobile number will enable e-verification of the ITR using Aadhaar by way of an OTP sent to the mobile number linked to Aadhaar.

Using e-Aadhaar requires verification via OTP sent to your mobile number.

Also, personal details linked to the Aadhaar online can be changed using an OTP sent to the registered mobile number.

Link the mobile number with Aadhaar is possible in two scenarios:

1. The linking is being done for the first time;

2. The linking has been done but there is a change in the mobile number. The Aadhaar data has to be updated by replacing the old number with the new one.

Linking mobile number to Aadhaar for the first time

The linking can only be done offline. Most online transactions are OTP (one-time-password) authenticated, i.e., the password is sent to the registered number. Since you are linking your number for the first time, online authentication is not possible. To do this offline you need to follow these steps:

Visit your nearest Aadhaar centre to get the Aadhar Update/Correction Form or download it from the UIDAI website.

(Click here to download the form).

Fill out the form correctly; submit it to the concerned person at the centre and mention on the form that only mobile number is to be updated.

While submitting the update form, along with photocopy of your Aadhaar card you also need to provide photocopy of an Identity proof document such as PAN Card, Passport, Voter ID card ( Click here for the complete list of supporting documents).

Following the submission your biometrics will be verified at the enrolment centre. Your thumb impression will be verified. While applying for Aadhaar your biometrics were recorded and to authenticate the changes, they are verified.

After verifying the biometrics, you will be given an acknowledgement slip. Usually it takes 2-5 working days for the updation to happen but as per the UIDAI helpline the turnaround time for the updation is 10 days.

Updating the mobile number

Updating a mobile number can be done online, but make sure that your existing number linked to your Aadhaar, is functional and handy. This is because the OTP to authenticate the updation would be sent to your existing number. You will be able link your new mobile number with Aadhaar only after submitting the OTP sent on your old number.
On the UIDAI website, there’s an option under the Aadhaar Update tab that will redirect the user to the Aadhar Self-Service portal.

(Click here to go to the portal directly)

Enter your Aadhar number, and the Captcha text and request for OTP.

The OTP will be sent to your existing mobile number, and after submitting it you’ll be redirected to a new page, where you can update the desired details.

Under ‘Select field(s) to update’, select ‘Mobile Number’

Now enter your new mobile number that you want to record in the database and submit.
