The Unique Identification Authority of India (UIDAI) provides four different formats of Aadhaar to residents in India. These include the Aadhaar Letter, eAadhaar, mAadhaar, and Aadhaar PVC Card. All four forms carry the same 12-digit Aadhaar number and are considered equally valid for identity verification and authentication.
Aadhaar is widely used across India for accessing government services, financial transactions, and identity verification. UIDAI states that residents can choose any format depending on their preference for digital access or physical documentation.
Aadhaar letter and eAadhaar
The Aadhaar Letter is the original paper-based document issued by UIDAI and delivered to a resident’s registered address through post. It contains demographic details along with a secure QR code that can be used for offline verification.
Another widely used format is eAadhaar, which is a digitally downloadable version of Aadhaar available from the UIDAI website. It is password-protected and digitally signed by UIDAI, making it legally valid for most verification purposes. Users can download eAadhaar after enrolling for Aadhaar or updating their details.
Both formats are commonly used for identity proof when applying for services such as bank accounts, telecom connections, and government schemes.
mAadhaar App and PVC
UIDAI has also introduced the mAadhaar mobile application, which allows users to carry their Aadhaar digitally on a smartphone. The app provides features such as offline Aadhaar verification, QR code scanning, and the ability to share Aadhaar details electronically.
Another format is the Aadhaar PVC Card, a compact plastic card that resembles a bank card. It includes security features such as a secure QR code, hologram, micro text, and a digitally signed photograph. Residents can order the PVC card online through the UIDAI portal.
Role of Aadhaar in identity and digital services
Experts say Aadhaar has become a central identity document in India, linking individuals to several services including subsidies, welfare schemes, and digital verification systems. Multiple formats of Aadhaar have been introduced to improve accessibility and make identity verification easier across physical and digital platforms.
Digital formats like eAadhaar and mAadhaar have also supported the expansion of online services where electronic identity verification is required.
Implications for residents and service providers
The availability of four formats allows residents to select a version that suits their usage patterns. While some prefer physical documents such as the Aadhaar Letter or PVC Card, others rely on digital formats for convenience.
Going forward, the expansion of digital governance and online verification systems may increase the adoption of electronic Aadhaar formats. However, UIDAI continues to emphasize that all four versions of Aadhaar remain valid and interchangeable for identification purposes.
