Everything you need to know about Aadhaar card

What is Aadhaar card?

Aadhaar is a 12-digit identification number in Aadhaar Card issued by the Unique Identification Authority of India (UIDAI) to Indian residents following a verification process.

Individuals must provide minimal demographic and biometric information to obtain an Aadhaar number, which includes their name, date of birth or age, gender, address, mobile number, e-mail ID (optional), fingerprints, iris scans, and a facial photo.

UIDAI has issued Aadhaar in a variety of forms, including Aadhaar letters, eAadhaar, mAadhar, and Aadhaar PVC for citizens. All kinds of Aadhaar are valid. Indians have the following options to choose:

  • Aadhaar Letter

Aadhaar letters are paper-based laminated documents that are sent to citizens after enrolment or after updating the information. In the event of a new enrolment or a mandatory biometric update, a free Aadhaar letter is mailed to the resident.

If the Aadhaar letter is damaged or lost, the person can purchase a copy for Rs 50 from UIDAI’s official website.

  • eAadhaar

eAadhaar is a password-protected, digitally signed electronic copy of Aadhaar. The password is a combination of the first four letters of the user’s name in capital letters and the year of birth (YYYY). The issue and download dates are included in eAadhaar, as well as a QR code for offline verification.

Residents can use the Mask Aadhaar option to hide their Aadhaar number in downloaded e-Aadhaar. The first eight digits of an Aadhaar number are replaced with characters such as “xxxx-xxxx,” leaving only the last four digits visible in a masked Aadhaar number.

According to the Aadhaar Act, e-Aadhaar is valid for all purposes. Residents can get their e-Aadhaar or masked e-Aadhaar from the official website of the UIDAI.

  • mAadhaar

mAadhaar is the official mobile app developed by UIDAI to allow Aadhaar users to carry their demographic data, such as name, date of birth, gender, and address, as well as photos, in smartphones. It has a QR code that may be used to validate it offline.

mAadhaar can be downloaded on all smartphones running iOS 10.0 or higher and Android 5.0 or higher. A user can add up to three profiles on one device, as long as all three profiles having same mobile number in their Aadhaar. This is true if members of a family use the same mobile number enrolled in their Aadhaar as the mAadhaar user.

The mAadhaar application is available for use anywhere in India at any time. mAadhaar is more than just a wallet-sized Aadhaar card. The mAadhaar app may be used to lock/unlock biometric data, share QR code and eKYC data, update the Aadhaar profile, and more.

  • Aadhaar PVC Card

UIDAI introduced the Aadhaar PVC card in October 2020. It is sturdy and portable. The PVC-based Aadhaar Card is a plastic card with several security measures, a digitally signed secure QR code, a photo, and demographic information.

By paying a fee of Rs 50, this kind of Aadhaar can be purchased online using an Aadhaar number, virtual ID, or enrolment ID. The card is mailed to the registered address after application.
