Here’s how to link your Aadhaar to a mobile number online

Linking Aadhar and mobile phone number allows easy verification of your identity and opens access to certain government services and monetary benefits.

Aadhaar, the 12-digit identification number issued by UIDAI, aims to ensure efficient dissemination of social security benefits and grants to residents of India. The Aadhaar number also serves as proof of your identity for various verification purposes. Now, to avail any of these facilities, your mobile number must be linked to your Aadhaar card as the process will involve verification via OTP. However, some of our mobile numbers might not be present in UIDAI records, if we did not submit the phone number at the time of Aadhaar registration. Well, don’t worry because here we will see how you can add your mobile number to the Aadhaar card.

On the other hand, if you just want to link your Aadhaar card to your mobile number, we will walk you through the steps. In short, we will address both of these concerns and more. So let’s get started.

How to Link Aadhaar with Mobile Number Online

This might be the most comfortable way to link your mobile number to an Aadhaar card online, as you don’t have to go to the Aadhaar Seva Kendra. Yes, you do not need to go to a service center or wait in line. Instead, you can complete the process by mail from the comfort of your home.

Here’s how it goes:
