UIDAI and Aadhaar

It is the brainchild of Sir Nandan Nilekani, who had the vision to deliver a unique identification number to each Indian, which would eliminate duplicate/fake identities cost-effectively. The government introduced Aadhaar, which also supports verification and authentication. The Unique Identification Authority of India was created to issue a 12-digit Unique Identification Numbers (UID) under Aadhaar to all the residents of India, besides other responsibilities mentioned above.

Objectives of UIDAI

The primary objective of the UIDAI is to issue a UID for every individual to prevent duplication of identities and for verification and authentication of identity in a cost-effective manner. 

Services provided by UIDAI

The UIDAI provides various services relating to Aadhaar online as well as offline. The following are the services offered by the UIDAI:

  • Aadhaar enrolment services:
    • Locating an enrolment centre
    • Booking appointment at an Aadhaar Seva Kendra
    • Checking Aadhaar status
    • Downloading Aadhaar
    • Order Aadhaar PVC card
    • Check Aadhaar PVC card status
  • Update Aadhaar services:
    • Update Aadhaar at enrolment centre
    • Check Aadhaar update status

Individuals can visit the official UIDAI website to access Aadhaar online services. They can get Aadhaar services offline through Aadhaar enrolment centres or Aadhaar Seva Kendras.

In an ongoing process of linking all the identity cards (driving license, PAN, voter ID, passport) and accounts (bank accounts, mobile numbers, etc.) with Aadhaar card, the government is mandating the linkage in a phased manner. Initially, it mandated to link the PAN and the bank account with the Aadhaar. Now, the government has made it mandatory to link PAN with Aadhaar. 


The UIDAI has released a new app for android and IOS users to enable Aadhaar holders to download their Aadhaar card on mobile phones and keep it handy. The app is known as the mAadhaar app. The app allows you to do the following:

  • Profile creation: The Aadhaar profile can only be created if you have a registered mobile number
  • You can lock and unlock your biometrics information
  • Virtual ID generation

Let’s look at the steps on how to create a profile in this app?

  • Input your 12-digit Aadhaar number.
  • Ensure that your mobile connection is active, key in the details and click on verify.
  • Enter the OTP sent to your registered mobile number, and your profile will be created.

The mAadhaar app also provides the following benefits:

  • Aadhaar holders can easily lock and unlock their biometrics identification services anytime.
  • A holder can share his eKYC through message or email directly.
  • One can now use the time-based OTP facility of the mAadhaar app, which will be valid for only 30 seconds.
  • This app allows the users to share the details using the QR code, preventing any data leakage.
  • A holder can order a newly printed Aadhaar card from the mAadhaar app by providing aadhaar details for the verification process and making a payment.

Role of UIDAI

In addition to the services offered, the UIDAI plays a vital role in ensuring confidentiality, good governance, and developing methods to provide a more robust system. Some places where the UIDAI plays an important role are:

  • To develop policy, procedure and system for issuing Aadhaar numbers to individuals who request the same by submitting their demographic information and biometric information by undergoing a process of enrolment.
  • To ensure availability, scalability and resilience of the technology infrastructure.
  • To ensure the security and confidentiality of individuals’ identity, information, and authentication records.
  • To ensure compliance with Aadhaar Act by all individuals and agencies.
  • To make regulations and rules consistent with the Aadhaar Act, for carrying out the provisions of the Aadhaar Act.

UIDAI Ecosystem

At the core of the system, the UIDAI has two procedures:

  • Enrolment and Update 

The enrolment procedure consists of registrars and enrolment agencies. In coordination with the registrars, the enrolment agencies set up enrolment centres where residents can enrol for Aadhaar. Multiple fingerprint scanners, iris scanners, and cameras certified by the UIDAI are set up and connected to the UIDAI-designed standard Application Programming Interface (API). A registrar is an entity authorised or recognised by UIDAI to enrol individuals. Enrolment agencies are appointed by registrars and are responsible for collecting demographic and biometric information of individuals during the enrolment process by engaging certified operators/supervisors.

  • Authentication 

The UIDAI has set up a scalable procedure for instant authentication of residents. The Aadhaar authentication ecosystem can handle tens of millions of authentications daily and can be scaled further as per demand. The Unique Identification Authority of India has appointed several Authentication Service Agencies (ASAs) and Authentication User Agencies (AUAs) from various governments and non-government organisations.

Frequently Asked Questions

What are the features and benefits of Aadhaar?

One Aadhaar: Aadhaar is a unique number, and no resident can have a duplicate number since it is linked to their individual biometrics; thereby identifying fake and ghost identities which result in leakages today. Savings from eliminating duplicates and fakes through Aadhaar-based identification will further enable governments to expand benefits to other eligible residents.
Portability: Aadhaar is a universal number, and agencies and services can contact the central Unique Identification database from anywhere in the country to authenticate a beneficiary's identity by availing authentication services.
Inclusion of those without any existing identity documents: A problem in reaching benefits to poor and marginalised residents is that they often lack the identification documents they need to receive State benefits; the "Introducer" system, which has been approved for data verification for the UIDAI will enable such residents to establish an identity.
Electronic benefit transfers: The UID-enabled bank account network will offer a secure and low-cost platform to directly remit benefits to residents without the heavy costs associated with benefit distribution today; as a result, the leakages in the current system will also be stemmed.
Aadhaar-based authentication to confirm entitlement delivered to the beneficiary: The UIDAI will offer online authentication services for agencies who wish to validate a resident's identity; this service will enable confirmation of the entitlement actually reaching the intended beneficiary. Improved services through increased transparency: Clear accountability and transparent monitoring would significantly improve access and quality of entitlements to beneficiaries and the agency alike.
Self-service puts residents in control: Using Aadhaar as an authentication mechanism, residents should be able to access up-to-date information about their entitlements, demand services and redress their grievances directly from their mobile phones, kiosks or other means. In the case of self-service on the resident's mobile, security is assured using two-factor authentication (i.e. by proving possession of the resident's registered Mobile Number and knowledge of the resident's Aadhaar PIN). These standards are compliant with the Reserve Bank of India's approved standards for Mobile Banking and Payments.

  • Names must not have salutations such as Mr / Mrs / Ms / Dr

Can the UIDAI Aadhaar card be made online?

What are the different forms of Aadhaar and what are their features?
