Verify Aadhaar number authenticity, e-KYC, demographic data and biometric records via UIDAI's official services.

Short Information

The Unique Identification Authority of India (UIDAI) is the statutory body established under the Aadhaar Act 2016 that issues 12-digit Aadhaar numbers to Indian residents. UIDAI provides multiple verification routes: Aadhaar number validation (checks the Verhoeff checksum without revealing demographic data), online e-KYC for authorised entities under the Authentication User Agency framework, QR-code verification on e-Aadhaar PDFs, and offline XML verification for service providers who don't have internet access. The myAadhaar portal lets residents check authentication history, lock biometrics, and update demographic data online. All Aadhaar verification respects the Aadhaar (Authentication) Regulations 2016 and requires explicit consent of the resident.

Form Instructions

To verify an Aadhaar number: 1) Visit https://myaadhaar.uidai.gov.in/verify-aadhaar.
2) Enter the 12-digit Aadhaar number and the displayed CAPTCHA.
3) Click 'Proceed' to confirm whether the number is valid and active.
To verify an e-Aadhaar PDF, open it in any QR scanner — the QR code carries digitally signed demographic data and a photo.
To run an offline e-KYC, residents download the password-protected XML from the myAadhaar portal and share it with the verifier; the verifier validates the digital signature using UIDAI's public key.
Authorised agencies must obtain AUA/KUA licences and complete UIDAI's onboarding before consuming live e-KYC APIs.
UIDAI's toll-free helpline is 1947.
