Link Aadhaar Number With Mobile

Link Aadhar Card to Mobile Number

Must Read: You can check a duplicate copy of aadhaar copy by following this article.


The first method is pretty simple and direct. The customer can directly go to a retail store of their telecom operator. Then hand over your Aadhar details to the executive there and directly link your existing mobile number to your Aadhar card. You need to carry your Aadhar card with you as the verification process will be completed only via a fingerprint scan.

Link Aadhar Using OTP

Another process is a hassle-free process and probably the faster between the two. This linking process is done via OTP sent to your mobile number.  You have to send 12 digit Aadhar number through an SMS to UID recipient number. Now you will get an OTP sent to you from UIDAI to your Aadhar registered mobile number. You don’t need to go any retail store and just complete the re-verification process directly from home. However, the OTP will be sent only to the mobile number you used in time of applying for your Aadhar card. So during the time of applying for the Aadhar card and verification process, if you change your phone number, you won’t be able to re-verify using this OTP method.

IVRS Method: Dial 14546

You have to dial a toll-free number 14546. Response a computer generated call via a keypad. Provide your 12 digit Aadhar number. You will receive an OTP on Aadhar registered number which you have to enter manually for authentication.

How to Update the Mobile Number Linked to your Aadhar Account?

This process can be done online as an OTP verification is required. So in order to do this, you need to go to the nearest Aadhar verification centre. Then you need to submit the relevant documents to the concerned executive there. Basically, you will need to submit your mobile number bill with the address, name, etc., as a mean of documentation. Then your new mobile number will be linked to the Aadhar card. Once this is done, you will receive an SMS from UIDAI saying the process is complete.

Things to know for foreign citizens, NRI’s who are Not registered in UIDAI

DoT did provide a way for foreign nationals to verify their numbers through an online process. They need to go to the telecom’s official website and fill up an online form and also upload copies of their passport and visa on it. This process will begin on the 1st of January, 2018.

There is a special category for senior citizens(above 70), NRIs and physically handicapped people who do not have Aadhar. They can fill a form online with documents as proof of age, residence or handicap, whatever the category. However, customers who belong to these three categories need to submit various required details of a “trusted person”. They will also need to submit Aadhar details of this “trusted person”. This trusted person will verify the mobile number user’s identity who selected him/her as his/her trusted person. A single person can be a “trusted person” for a maximum of only five individuals. However, the deadline for this is also same. All of this needs to be completed within 31st of March, 2018.
