How to link Adhaar with Mobile Number


Aadhaar has undoubtedly become a important document to establish your identity and avail the government's social security schemes and recently also for financial matters such as filing tax returns and keeping your bank account active. 

If you're looking to link your mobile number with Aadhaar, there can be two scenarios: 
1. You are linking it for the first time 
2. You have changed your phone number and want to update your Aadhaar data by replacing the old number with the new one. 

Linking your mobile number to Aadhaar for the first time: 
This needs to be done offline. Most online transactions are OTP (one-time-password) authenticated i.e. the OTP is sent to the registered mobile number. Obviously, online authentication is not possible as you are linking your number for the first time. To do this offline you need to follow these steps:


  • Visit your nearest Aadhaar centre
  • 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, Vot .. 

Updating your mobile number 
Updating the mobile number can be done online, but make sure that your existing number linked to your Aadhaar, is functional and handy before you go for the online update. 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: https://resident.uidai.gov.in/verify-email-mobile) 
  • Enter your Aadhar number, and the Captcha text and request for OTP. 
  • The OPT 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' ..
