Aadhaar Verification – Complete Guide 2025

The Aadhaar Card, issued by the Unique Identification Authority of India (UIDAI), has become the most widely accepted proof of identity in India. From opening a bank account to getting a SIM card, from filing income tax returns to availing government subsidies, Aadhaar is mandatory in most services.

But how do you check if an Aadhaar number is genuine? That’s where Aadhaar Verification comes in. UIDAI provides a secure way to verify the authenticity of any Aadhaar card online and offline.

This detailed guide explains everything about Aadhaar Verification: why it’s important, how to verify, the methods available, security features, and FAQs.

🔑 What is Aadhaar Verification?

Aadhaar Verification is the process of confirming whether a given Aadhaar number is:

  • Valid and issued by UIDAI.
  • Linked with the correct demographic details (name, age, gender, state).
  • Active and not cancelled or deactivated.

Verification can be done online through the UIDAI portal, by scanning the QR code printed on Aadhaar, or via offline methods like Aadhaar XML and mAadhaar app.

📌 Why Aadhaar Verification is Important

  1. Prevent Fraud: Fake or duplicate Aadhaar numbers can be detected.
  2. Mandatory for Services: Banks, telecom operators, and government offices often verify Aadhaar before providing services.
  3. Ensures Correct Identity: Helps confirm identity of employees, tenants, students, or customers.
  4. Legal Requirement: Many government schemes mandate Aadhaar verification before benefits are released.
  5. Instant Authentication: Provides a quick and digital method to check authenticity.

🛠️ Methods of Aadhaar Verification

UIDAI provides multiple ways to verify Aadhaar:

  1. Online Aadhaar Number Verification (UIDAI Portal)
  2. QR Code Scan Verification
  3. Aadhaar Offline XML Verification
  4. mAadhaar App Verification
  5. Biometric Authentication (Fingerprint/Iris)

📱 2. Verify Aadhaar Using QR Code

Every Aadhaar card (PVC, paper, or e-Aadhaar) has a secure QR code.

  • Download the mAadhaar app or use any QR scanner with Aadhaar verification support.
  • Scan the QR code on Aadhaar.
  • The app will show demographic details (name, gender, DOB, photo) and verify authenticity.

📑 3. Aadhaar Offline XML Verification

UIDAI provides a feature to share Aadhaar details via a digitally signed XML file.

  • Visit UIDAI portal → Aadhaar Offline eKYC.
  • Generate XML file with a share code.
  • Share this file instead of Aadhaar number.
  • Organizations can verify details using UIDAI’s verification tools.

This protects privacy since only limited information is shared.

  • Add your Aadhaar profile using OTP.
  • Use in-app features to verify QR codes or share details offline.

Some services (like banks or government subsidies) require live biometric verification.

  • Fingerprint or iris scan is captured via certified devices.
  • Verified against UIDAI database in real time.
  • Confirms authenticity of both Aadhaar and the person.

🔐 6. OTP-Based Aadhaar Verification

  • Enter Aadhaar number on the service provider’s portal.

This is commonly used for eKYC in telecom, banks, and digital wallets.

  1. Digitally Signed QR Code on every Aadhaar.
  2. UIDAI Encryption to prevent misuse.
  3. Limited Disclosure – Only minimal demographic details shown during verification.
