In today’s world, the Aadhaar card is an essential document for nearly every citizen. It is crucial to keep it updated as it is required for a variety of purposes, including securing jobs, obtaining ration cards and PAN cards, and even for travel.

If your card was issued about 10 years ago and hasn’t been updated since, you can make these changes for free until September 14. To ensure your details are accurate, you'll need to provide proof of identity and proof of address. 

Following the aforementioned deadline, the Unique Identification Authority of India (UIDAI) will enforce a Rs 50 penalty for delayed updates. 

The authentication process entails submitting your number, along with either demographic or biometric information, to UIDAI's Central Identities Data Repository (CIDR). UIDAI will then authenticate the correctness of your details against its database. 

How to update your Aadhaar Card : 

1. To start off, navigate to the official website of Aadhaar at https://myaadhaar.uidai.gov.in/. Once there, log in by entering your registered mobile number and the one-time password (OTP) that you will receive promptly.

2. Once logged in, carefully review the identity and address information presented in your profile.

3. In case you spot any discrepancies in the details shown on your profile. (Should you find the details are accurate, remember to select the 'I verify that the above details are correct' tab.)

4. From the drop-down menu provided, select the specific identity document you intend to submit for verification purposes.
