ABHA Address & ABHA Number
ABHA consists of two complementary components that together form a patient's digital health identity:
- ABHA Address (format:
name@abdm) - A human-readable username that patients use to access, manage, and share their digital health records. Functions as a healthcare-specific identity handle. - ABHA Number (14-digit unique identifier) - Issued after KYC verification via Aadhaar. Multiple ABHA Addresses can be linked to a single ABHA Number, providing a verified, government-linked health identity.
Why ABHA matters
ABHA is the entry point to the entire ABDM ecosystem. Without ABHA, patient records cannot be linked, consented, or shared. For hospitals, enabling ABHA at patient registration is Milestone 1 of ABDM compliance, and the foundation of all subsequent interoperability.
