Aadhaar Used for Voter Enrolment to Improve Accuracy and Prevent Duplicate Votes

  • Aadhaar linking aims to remove duplicate and fake entries from voter rolls improving election accuracy and transparency in India.

  • The Election Commission allows voluntary Aadhaar linking to streamline voter enrolment without denying anyone the right to vote.

  • Recent legal changes permit Aadhaar use for voter ID linking with safeguards to protect data privacy and ensure compliance with court rulings.

Aadhaar, India’s largest biometric identification system, has become a significant part of the country’s governance infrastructure. Among its many uses, Aadhaar’s role in voter enrolment has attracted considerable attention and debate.

This article explains how Aadhaar has been used for voter enrolment in India, the legal and regulatory context, benefits and challenges, historical background, technical details, and the current policy framework. By the end, you will have a clear and well-rounded understanding of why Aadhaar is used, how it helps, and what safeguards are in place to protect citizens' rights.


Background of Voter Enrolment in India

India has the world’s largest electorate. Maintaining a clean, accurate, and updated electoral roll is a fundamental need for the integrity of democratic elections.

Historically, voter rolls in India have faced issues like:

  • Duplicate entries

  • Fake voters

  • Outdated records of deceased people

  • Migration-related errors

Cleaning the voter rolls has therefore been an ongoing challenge for the Election Commission of India (ECI).


Introduction of Aadhaar in Voter Enrolment

Aadhaar, with its biometric-backed unique identification, was seen as a solution to authenticate voter identity and eliminate duplicates.

In 2015, the Election Commission of India (ECI) launched the National Electoral Roll Purification and Authentication Programme (NERPAP). The objective was to link the Elector Photo Identity Card (EPIC) with Aadhaar numbers to:

  • De-duplicate voter entries

  • Improve accuracy of voter rolls

  • Simplify verification processes

Aadhaar provided a reliable way to verify identity, as each Aadhaar number is unique and biometrically validated.


Legal Challenges and Supreme Court Restrictions

However, the Supreme Court of India put limitations on mandatory use of Aadhaar for welfare and non-welfare services to protect privacy.

In August 2015, following concerns over privacy, the Court restrained the government from making Aadhaar mandatory for availing services, including voter enrolment.

This meant that linking Aadhaar with voter ID had to be voluntary, not compulsory.


Representation of the People Act Amendment (2021)

To provide clear legal backing, the Representation of the People Act, 1950 was amended in December 2021.

Key points of the amendment:

  • Enabled voluntary linking of Aadhaar with voter IDs

  • Objective: Remove duplicate entries from electoral rolls

  • Aadhaar submission remained optional to protect citizens’ voting rights

The Election Laws (Amendment) Act 2021 specifically states that no person shall be denied inclusion in the electoral roll if they cannot furnish Aadhaar.


How Aadhaar Linking Works

The process of Aadhaar linking with voter ID is simple:

  • Voters can submit Form 6B online or offline to the Election Commission

  • Provide their Aadhaar number voluntarily

  • Verification is done using Aadhaar database

This data is used only for de-duplication, ensuring a person is registered only once in the electoral rolls.

Important: The Election Commission has clarified that voting rights cannot be denied if Aadhaar is not linked.


Benefits of Aadhaar Linking

The benefits claimed for Aadhaar-based voter enrolment include:

  • Removing duplicate and fake voter entries

  • Ensuring clean and accurate electoral rolls

  • Preventing impersonation during elections

  • Improving the efficiency of the enrolment process

  • Saving costs associated with manual verification

By linking Aadhaar, the Election Commission can maintain one-person-one-vote integrity.


Privacy Concerns and Safeguards

Despite the benefits, Aadhaar linking has raised privacy concerns:

  • Potential misuse of data

  • Risk of voter profiling

  • Lack of robust data protection laws (though India has enacted a Digital Personal Data Protection Act)

To address these, the Election Commission:

  • Makes linking voluntary

  • Encrypts and protects Aadhaar data

  • Uses Aadhaar only for de-duplication, not for public display


Current Status of Aadhaar-Voter ID Linking

As of 2025:

  • Voter enrolment using Aadhaar is voluntary.

  • Voters can provide Aadhaar to improve roll accuracy.

  • No one can be removed from the rolls for not having Aadhaar.

The Election Commission continues public awareness campaigns to encourage voluntary linking.


International Comparisons

Globally, countries use various methods to maintain clean voter rolls:

  • The USA uses Social Security Numbers in some states

  • European countries rely on national ID registers

  • Biometrics are used in places like Ghana and Nigeria

India’s use of Aadhaar is part of this global trend to enhance electoral integrity.


The Role of Technology in Electoral Reforms

Aadhaar is only one part of India’s push for electoral reform.

Other reforms include:

  • Online voter registration

  • Voter helplines and apps

  • Electronic Voting Machines (EVMs)

  • Voter Verified Paper Audit Trail (VVPAT)

  • Remote Voting solutions in pilot stages

All these aim to make elections transparent, accessible, and credible.


The Debate: Benefits vs Concerns

Proponents argue that Aadhaar linking:

  • Prevents fraud

  • Strengthens democracy

  • Saves public money

Critics warn of:

  • Privacy risks

  • Potential exclusion

  • Surveillance fears

It is essential for policymakers to balance these concerns with robust legal safeguards and transparent processes.


Future of Aadhaar in Elections

Looking ahead:

  • Aadhaar-based verification may expand for postal ballots and service voters.

  • AI-based systems might cross-verify electoral rolls.

  • India’s new data protection regime will influence how Aadhaar data is handled.

Ensuring citizen trust will require:

  • Transparency in data use

  • Independent oversight

  • Public awareness


Conclusion

Aadhaar has been actively used in India for voter enrolment since 2015—first in pilot mode, later with legal backing for voluntary use.

It offers clear benefits in fighting duplication and improving roll accuracy, but must be implemented carefully to protect citizens’ privacy and rights.

The Election Commission’s current approach of voluntary linking, combined with legal safeguards, seeks to balance electoral integrity with individual freedoms.

India’s democratic health depends on maintaining this balance as technology continues to evolve.
