What Is Aadhaar Verification API?

An Aadhaar Verification API is a secure digital tool that lets businesses connect to India’s UIDAI database to instantly verify a person’s identity using their Aadhaar number, biometrics, or registered mobile number (OTP), enabling real-time KYC, fraud prevention, and seamless digital onboarding for services like banking, telecom, and government processes. It acts as a bridge, allowing applications to request and receive authenticated user data (name, DOB, address, photo) directly from the central system, ensuring accuracy and compliance. 

Aadhaar Verification API Work

The Aadhaar Verification API is a digital tool that enables businesses and entities (known as Authentication User Agencies or AUAs) to instantly confirm an individual’s identity against the Unique Identification Authority of India’s (UIDAI) central database. This system streamlines the Know Your Customer (KYC) process, reduces fraud, and facilitates secure, paperless transactions across various sectors in India. 

How the Aadhaar Verification API Works

The general workflow for an Aadhaar verification via API is a secure, multi-step process: 

1. User Consent: The process legally requires obtaining explicit consent from the individual for their Aadhaar information to be used for verification.
2. Data Submission: The user provides their Aadhaar number and other required information (like a fingerprint, iris scan, or an OTP) through the AUA’s application or website.
3. API Request: The AUA’s system securely bundles and encrypts this data and sends a request to the Aadhaar Verification API endpoint, which then communicates with the UIDAI’s Central Identities Data Repository (CIDR).
4. Verification and Match: The UIDAI system verifies the submitted details (demographic or biometric) against the information stored in its database.
5. Response: The Aadhaar verification API receives a “Yes” (match) or “No” (no match) response from the UIDAI. Importantly, the Aadhaar verification API does not return personal identity information itself, only the status of the match, to protect user privacy.
6. Action: The AUA’s system takes appropriate action based on the response (e.g., completes customer onboarding, grants access to a service, or flags the transaction for manual review). 

Types of Authentication Methods

The Aadhaar verification API supports several verification methods to suit different business needs: 

• OTP-Based Authentication: A One-Time Password is sent to the Aadhaar-registered mobile number/email address and entered by the user for verification. This is quick and user-friendly for remote onboarding.
• Biometric Authentication: Uses physical attributes like fingerprints or iris scans for verification. This is highly secure and typically used for in-person verification or high-security applications.
• Demographic Authentication: Matches basic information (name, date of birth, address) provided by the user with the UIDAI database. This is a quicker method for low-risk needs.
• Offline e-KYC (XML/QR Code): The user downloads an encrypted XML file or allows scanning of a QR code from their mAadhaar app/card, which the Aadhaar verification API uses for verification without needing real-time UIDAI access.

Benefits of Seamless Identity Verification

Adopting compliant Aadhaar APIs offers substantial benefits, transforming traditional, paper-based processes into efficient digital workflows: 

• Speed and Efficiency: Reduces customer onboarding time from days to seconds, allowing for instant service provisioning.
• Fraud Prevention: Enhances security through multi-factor authentication (biometrics, OTP), which significantly mitigates identity fraud, theft, and the use of forged documents.
• Cost-Effectiveness: Automates processes, minimizing manual labor, paperwork, and associated operational costs.
• Regulatory Adherence: Ensures alignment with mandatory KYC and Anti-Money Laundering (AML) norms set by Indian regulatory bodies, avoiding penalties and legal issues.
• Improved User Experience: Provides a fast, friction less, and secure experience, building customer trust and loyalty. 

Aadhaar Verification API Legal Considerations

The legal use of Aadhaar Verification APIs in 2026 is governed by the Aadhaar Act, 2016 (as amended) and strict guidelines from the Unique Identification Authority of India (UIDAI), focusing heavily on user consent, data minimisation, and stringent security protocols. Aeps india can only use the APIs after registering with the UIDAI as an Authentication User Agency (AUA) or partnering with a licensed intermediary. 

Key Legal and Compliance Considerations for 2026

• Mandatory UIDAI Registration for Private Entities: In a significant policy shift, the UIDAI now mandates that all “Offline Verification Seeking Entities” (OVSEs), including hotels, event organisers, and e-commerce platforms, must register with the authority before using any Aadhaar-based verification method, including APIs or QR codes. This aims to create a controlled and auditable ecosystem.
• Explicit User Consent is Mandatory: The Aadhaar Act, Section 8, strictly requires that entities obtain explicit consent from the individual (Aadhaar number holder) for each verification request. The individual must be informed about the specific purpose of the verification and the information that will be shared.
• Data Minimisation and Zero Storage Policy: A core legal requirement is the prohibition of storing raw Aadhaar numbers and biometric information.
  • No Permanent Storage: Biometric and OTP data captured for authentication must not be stored on any permanent storage or database.
  • Aadhaar Data Vault (ADV): Entities that need to store any Aadhaar-linked data (like reference IDs or eKYC data) must use a secure, UIDAI-compliant Aadhaar Data Vault. Storing Aadhaar numbers in open databases is strictly prohibited.
  • Tokenization: The use of tokenization, which replaces the actual Aadhaar number with an encrypted reference ID, is a key compliance measure to minimize data exposure risk.
• Purpose Limitation: Information obtained through Aadhaar APIs must only be used for the specific purpose stated during the consent process. Using the data for any other reason carries penalties, including imprisonment and significant fines.
• Security and Audits: Entities must maintain robust security measures as approved by the UIDAI.
  • Encryption: Personal Identity Data (PID) blocks must be encrypted at the point of capture and should never be sent over a network in the clear.
  • Audit Trails: Detailed logs and audit trails of all Aadhaar interactions must be maintained for potential audits by the UIDAI or its agencies.
  • Hardware Security: All cryptographic processes should occur within a FIPS 140-2 Level 3 certified Hardware Security Module (HSM).
• Regulatory Alignment: The use of Aadhaar APIs helps businesses, particularly those in finance and insurance, meet other regulatory compliance mandates such as Know Your Customer (KYC) norms, Anti-Money Laundering (AML) standards, and the Reserve Bank of India’s (RBI) two-factor authentication requirements.
• Focus on Offline Verification: The UIDAI is actively promoting the use of secure offline verification methods, such as the QR code printed on the Aadhaar letter, to further reduce the risk of misuse associated with collecting and storing photocopies or raw data. 

Entities leveraging Aadhaar Verification APIs must ensure their systems and practices strictly adhere to the guidelines outlined on the official UIDAI website to remain compliant and avoid legal repercussions in 2026.
