Aadhaar Card

Aadhaar Card: The Ultimate Guide to India's Unique Identification Number


In a country as vast and diverse as India, a robust system of identification is necessary to ensure efficient governance and access to essential services. The Aadhaar Card is a unique identification number issued by the Indian government, serving as proof of identity and address for residents of India. In this comprehensive guide, we will delve into the intricacies of the Aadhaar Card, exploring its features, benefits, application process, updates, and much more.

Understanding Aadhaar Card

The Aadhaar Card is a 12-digit number issued by the Unique Identification Authority of India (UIDAI), a statutory authority established in 2009. It acts as a centralized database containing the biometric and demographic data of individuals residing in India. The card includes essential information such as the individual's full name, gender, date of birth, address, and a unique Aadhaar number. Additionally, the Aadhaar Card features a photograph, biometric data (fingerprints and iris scan), and a QR code for easy access to the cardholder's details.

Baal Aadhaar: Aadhaar Card for Children

Children are not exempt from the benefits of the Aadhaar Card. The Baal Aadhaar, also known as Aadhaar for children, is a blue-colored Aadhaar Card specially designed for minors. It serves as a valid proof of identity and address for children and can be utilized for government schemes, education, immunization, and travel purposes. While the Baal Aadhaar does not initially include biometric information, children aged five and above are required to update their cards with biometric data. Furthermore, when a child reaches the age of 15, another biometric update is necessary for the Aadhaar Card.

However, children aged 5 and above are required to provide their biometric data and update their Aadhaar Card accordingly. Additionally, when a child turns 15, further biometric updates are necessary.

After submitting your Aadhaar Card application, you can track its status online. Follow these steps to check the progress of your application:

  3. Virtual ID (VID): A Virtual ID is a 16-digit unique code generated by the UIDAI for each Aadhaar Card holder. It serves as an alternative to the actual Aadhaar number for authentication purposes. The VID can be used to protect your Aadhaar number when furnishing it to different agencies.

Updating Aadhaar Card Details

To ensure accurate and up-to-date information on your Aadhaar Card, it is essential to update any changes in details such as your name, address, phone number, and more.

It's worth noting that name changes can only be done twice, and address and gender changes can only be made once. For changes beyond these limits or other complex updates, a visit to a UIDAI regional office is necessary.
