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 Unique Identification Numbers (UID) under Aadhaar to all the residents of India, besides other responsibilities mentioned above.

Services provided by UIDAI

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, the government is mandating the linkage in a phased manner. Currently, it is mandatory to link the PAN and the bank account with the Aadhaar. The UIDAI provides services relating to Aadhar online as well as offline. The services range from updating the details of the registered person to correcting data and checking the status of requisitions raised. For availing these services offline, one may visit an enrolment centre with the required documents and have their issues resolved.


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 Aadhar 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 Aadhar. 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 Aadhar 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.

Organisational Structure of UIDAI

The DDGs are assisted by Assistant Directors General (ADGs), Deputy Directors, Section Officers and Assistant Section Officers. The HQ has a total sanctioned strength of 127 officers and staff members, including the accounts and IT branches. Each regional office is headed by a Deputy Director General (DDG). The support structure comprises assistant director general, deputy director, section officers, assistant section officers, senior accounts officer, accountant and personal staff.

Grievances Redressal of UIDAI

Grievances at UIDAI are received through the following modes:

  • UIDAI Contact Centre
    UIDAI has set up a Contact Centre for handling queries and grievances related to Aadhaar enrolment, updation and other services. When a resident approaches an enrolment centre, the operator gives a printed acknowledgement for registering the complaint. The resident can further follow up on the status updates by quoting the number from the acknowledgement slip.
  • Post
    Residents have an option to post their grievances to the headquarter or regional offices of the Unique Identification Authority of India. The grievances are examined and then forwarded in hardcopy to the concerned officer/public grievance officer at UIDAI. The concerned regional office/concerned section disposes of the grievance by replying directly to the complainant under intimation to the grievance cell, UIDAI.
