Have you linked your Aadhaar number with mobile SIM? Now, many telecom operators are offering a toll-free service – 14546 – for re-verification of your Aadhaar number on your mobile phone through an IVRS or Interactive Voice Response System. Mobile phone users can dial 14546 to link their Aadhaar number with the mobile number through IVRS-based OTP (One-Time PIN) verification. The UIDAI or Unique Identification Authority of India – the issuer of the 12-digit Aadhaar number – has issued directives for generating OTP either through the service provider’s website or through the Interactive Voice Response (IVR) services to facilitate the Aadhaar linking with mobile phone number, the government has said on microblogging site Twitter.

How to link Aadhaar with mobile phone number

If you want to re-verify your phone number by linking it to Aadhaar, the process is rather simple. You just need to keep your Aadhaar number at hand. Whether you are on Airtel, Idea, Jio, and Vodafone or any other operator, you simply need to call the toll-free number 14546 from the phone number. Follow these steps, as directed by the IVR, to complete the re-verification process.

  1. When you call 14546, you will be asked to select whether you are an Indian national or an NRI by selecting the respective option
  2. Next, you will have to give consent to link Aadhaar with your phone number by pressing 1
  3. After that, you need to provide your Aadhaar number and press 1 to confirm
  4. This step generates the OTP, which you will receive on your mobile phone
  5. Now, you need to enter your phone number
  6. Here, you are asked to give consent to your operator to pick your name, photo and date of birth from UIDAI data base
  7. The IVR now mentions the last four digits of your number to confirm that you have keyed in the right number
  8. If the number is correct, you can enter the OTP you received on SMS
  9. You must press 1 to complete the Aadhaar-mobile number re-verification process
  10. If you hold another phone number, you can link that too by pressing 2 and following the steps provided by the IVR system. Keep your other mobile phone handy as you will receive the OTP on this number.

The OTP you receive for Aadhaar-mobile phone re-verification is valid for 30 minutes, so you can use it even there is some network glitch and the call terminates prematurely. Subscribers who are on corporate plans do not need to need to undergo the re-verification process. So far, Airtel, Idea, and Vodafone have activated the service. Since Jio takes Aadhaar number to activate the SIM card, subscribers do not need to re-verify on the network, a customer care executive told 

How to Link Aadhaar with Mobile Number Online through Call or SMS

Back in November last year, the UIDAI approved the proposals to implement new modes like OTP for Aadhaar-based SIM re-verification of existing subscribers. People with their mobile numbers already in UIDAI database could avail these services from December 1, according to the Aadhaar-issuing body.

Aadhaar holders could also opt for verification via operators’ mobile applications, or use the mAadhaar app on Android for it.

Here are the steps to link SIM card to Aadhaar card

  1. This procedure needs to be done offline by visiting the nearest Aadhaar centre. There will be no OTP as you are linking your number for the first time. Click here to download the form
  2. An individual needs to fill out the form correctly and submit it to the concerned person at the centre. One needs to mention on the form that only mobile number is to be updated.
  3. While submitting the update form, along with a photocopy of your Aadhaar card you also need to provide a photocopy of an Identity proof document such as PAN Card, Passport, Voter ID card. After the submission is done, your biometrics will be verified at the enrollment centre. Your thumb impression will be verified.
  4. 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.

How to update the mobile number:

If individual wishes to update the mobile number, it can be done online on UIDAI website. For this, individuals should make sure that their existing mobile numbers are linked to their Aadhaar numbers as the OTP to authenticate the updation would be sent to your existing number. You will be able to link your new mobile number with Aadhaar only after submitting the OTP sent on your old number.

  1. Visit the official UIDAI website,
  2. Click on the option ‘Aadhaar Update Online’ under Aadhaar Update category which will redirect the users to Aadhaar Self-Service portal.
  3. Enter your Aadhaar number and the Captcha text and request for OTP. The OPT will be sent to your existing mobile number.
  4. After entering the OTP, the users will be redirected to a page where customers can update the desired details.
  5. 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.

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.

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.

As Aadhaar is a central number, Airtel and Vodafone say users can link their mobile numbers to Aadhaar irrespective of the state it is issued in and the circle the number belongs to. However, Idea Cellular in a tweet said the Aadhaar number should belong to the same circle as the mobile number. Aircel has not started the IVR process, and is still asking users to go to offline stores even after the new centralised number has been deployed.

In late November, telecom operators had also been directed to set up a website so that subscribers can link Aadhaar and mobile number online. However, there is no such website so far. Going by the image in a tweet by the Digital India Twitter account, it seems users will be able to link the two using the mAadhaar app, which is available only for Android so far, as well in some time.

How to Link Aadhar with Mobile Number

The ongoing Aadhaar-mobile SIM card re-verification process has just become a little easier for people across the country.

The subscribers can use this method to re-verify other mobile numbers that they are using.

  • Agent-Assisted authentication

The agent-assisted authentication method is secure and easy. The telecom operators are instructed not to disclose the complete KYC details of subscribers to agents unlike in the past.
