Aadhaar is distributed by the UIDAI in four different formats, including Aadhaar letter, mAadhaar, eAadhaar, and PVC card. In the event of new enrollments or required biometric upgrades, people are issued a laminated letter from Aadhaar.
Individuals may download eAadhaar in electronic mode. Additionally, they may download the mAadhaar in digital form on their phones. The PVC card is a sturdy, wallet-friendly card that is the size of a pocket.
You may utilize any of the four Aadhaar identification proofs, depending on your preference and convenience. There is no preference for one form of Aadhaar over the others.
