In order to make Aadhaar more convenient for residents, the Unique Identification Authority of India (UIDAI) has regularly developed other formats of Aadhaar.

What is Aadhaar

Aadhaar is a verifiable 12-digit identification number issued by UIDAI to residents of India. According to the UIDAI website, below are the valid Aadhaar formats which can be used as proof.

According to the UIDAI tweet, “All forms of Aadhaar issued by UIDAI are equally valid.”

Aadhaar Letter

Aadhaar Letter is a paper-based laminated letter with a secure QR Code with issue date and print date.

In the event of a new enrollment or required biometric update, an Aadhaar letter is free of charge and is issued to the resident via regular mail. The resident can order a replacement Aadhaar letter online from the UIDAI website for Rs. 50 if the original is lost or damaged. The resident will be sent a reprinted Aadhaar letter by speed post.


The electronic version of Aadhaar, or eAadhaar, is password-protected, has an Aadhaar secure QR code for offline verification, and is digitally signed by UIDAI. Using their registered mobile number, residents can quickly get their eAadhaar or disguised eAadhaar from UIDAI’s official website. Every Aadhaar enrollment or update immediately generates an eAadhaar, which is available for free download.

According to the Aadhaar Act, an electronic version of an Aadhaar is just as valid as a physical copy for all purposes.


mAadhaar is an official mobile application created by UIDAI. It offers Aadhaar number holders an interface to carry their Aadhaar records as registered with CIDR, which includes their Aadhaar number along with demographic data and a photo. An Aadhaar secure QR code is present for offline verification. Similar to eAadhaar, which is automatically generated with every Aadhaar enrolment or update, mAadhaar is also available for free download.

The mAadhaar profile is recognised as a valid ID proof by airports and railways; on the other hand, residents can utilise the app’s features to share their eKYC.

Aadhaar PVC Card

The most recent version of Aadhaar that UIDAI has released is the PVC Card. The PVC-based Aadhaar Card incorporates several security elements, a digitally signed Aadhaar secure QR code, a photo, and demographic information in addition to being lightweight and durable.
