UIDAI: Unique Identification Authority of India
The Unique Identification Authority of India, widely known as UIDAI, is a statutory authority established by the Government of India under the provisions of the Aadhaar Act of 2016. Initially part of the National Institution for Transforming India (NITI Aayog), UIDAI was later positioned under the Ministry of Electronics and Information Technology (MEITY) to enhance its regulatory operations.
Vision
UIDAI aims to empower every citizen of India with a unique identity, offering a digital platform for authentication accessible any time and anywhere.
Mission
UIDAI's mission focuses on delivering good governance characterized by efficiency and transparency to the citizens of India through unique identity numbers. Key objectives include:
- Promoting good governance by efficiently providing benefits and services through unique identity numbers.
- Developing policies, procedures, and systems for issuing Aadhaar numbers based on demographic and biometric enrollment.
- Ensuring the technology infrastructure's availability, scalability, and resilience.
- Developing systems for Aadhaar users to update and authenticate their digital identity effectively.
- Establishing a sustainable association to propagate UIDAI values.
- Ensuring Aadhaar Act compliance among individuals and agencies.
- Upholding the security and confidentiality of individual identity and authentication records.
- Formulating consistent rules with the Aadhaar Act to execute its provisions.
UIDAI and Aadhaar Identification
UIDAI’s primary mandate is providing each Indian citizen with a unique identification number, realized through the Aadhaar program. This 12-digit unique identity number aims to prevent fake or duplicate identities, promoting a robust system that combats fraud through cost-effective verification.
According to the Aadhaar Act of 2016, UIDAI is the sole authority overseeing:
- Aadhaar Enrollment
- Aadhaar Authentication
- Operation and management of the Aadhaar life-cycle
- Development of Aadhaar policy
- Systems for Aadhaar number issuance
- Security of identity information and authentication records
Functions
The Indian government aims to integrate individual identity cards and accounts, such as Driving License, Voter's ID, PAN, and Passport, with Aadhaar. This integration extends to mobile numbers and bank accounts. Linking PAN and bank accounts with Aadhaar is mandatory, as highlighted in PAN-Aadhaar linking guidelines. UIDAI facilitates numerous Aadhaar-related services online and offline, including detail updates, data corrections, and request status reviews. Offline services are available through enrollment centers.
System Procedures
The UIDAI employs two main procedures within its system:
- Enrolment & Update
- Authentication
Enrolment & Update
Enrolment involves Registrars authorized by UIDAI to enroll individuals, with Enrolment Agencies appointed to gather demographic and biometric data. These agencies partner with Registrars to set up enrollment centers where individuals can update their Aadhaar details.
Authentication
For instant authentication, UIDAI provides a scalable system managed by appointed Authentication Service Agencies (ASAs) and Authentication User Agencies (AUAs) across government and private sectors. This ecosystem can handle millions of authentication requests daily.
Grievances
UIDAI addresses grievances through several channels:
UIDAI Contact Centre
The UIDAI Contact Centre assists with Aadhaar enrollment, updates, and other services. At enrollment centers, individuals receive an acknowledgement for queries or complaints, which they can track using the reference ID.
UIDAI Public Grievance Portal
Grievances are processed through the UIDAI Public Grievance Portal, then routed online to relevant authorities, such as the Directorate of Public Grievances (DPG) or Department of Administrative Reforms & Public Grievances (DARPG).
UIDAI officials also respond to grievances received via email, addressing issues directly with complainants while keeping the grievance cell informed.
Post
Individuals may send grievances by post to UIDAI Headquarters or Regional Offices. The Public Grievance Officer then contacts the concerned department for resolution.
