How to Prevent Aadhaar Fraud?

Aadhaar is an essential ID proof in India, making documentation processes streamlined. But with this benefit comes a high risk of fraud. But UIDAI’s database is top-notch. How can one be defrauded through Aadhaar? There are multiple ways in which you can get an Aadhaar card fraud – like phishing scams, OTP scams, buying a SIM card on your card, taking out loans in your name, etc. This article will cover the common Aadhar Card-related frauds and how to prevent them.

How to Prevent Aadhaar Fraud?

What Is Aadhaar Card Fraud?

Aadhaar card fraud refers to the unauthorised use of your Aadhaar number, biometrics, or identity to complete KYC, issue SIM cards, open bank accounts, apply for loans, or conduct financial transactions without your permission. It occurs when fraudsters exploit personal information or authentication methods to impersonate you.

Potential consequences of Aadhaar fraud:

  • Identity theft and impersonation
  • Loan fraud or credit taken in your name
  • Issuance of SIM cards used for scams
  • Banking misuse or unauthorised transactions
  • Long-term financial and legal complications

How to Prevent Aadhaar Card Fraud?

UIDAI offers multiple online and offline security tools that help every Aadhaar holder protect their identity, biometrics, and authentication data. By enabling these features and reviewing your activity regularly, you can prevent misuse and maintain control over where and how your Aadhaar is used. The steps below will guide users on how to secure their Aadhaar effectively.

1. Download Masked Aadhaar

A masked Aadhaar hides the first 8 digits of your Aadhaar number and shows only the last four, making it safer to share for verification.

How to download masked Aadhaar:

  • Visit the official UIDAI website and open the “Download Aadhaar” section.
  • Enter your Aadhaar number/VID/Enrolment ID and complete OTP verification.
  • Select “Masked Aadhaar” before downloading the PDF.
  • On the Aadhaar App, open your profile → Download Masked Aadhaar → Authenticate with OTP.

2. Lock Your Aadhaar Biometrics

Locking biometrics ensures that no one can use your fingerprints, iris, or face for authentication without your permission.

Steps to lock/unlock biometrics:

  • Go to the UIDAI “Lock/Unlock Biometrics” service or open the Aadhaar App.
  • Enter your Aadhaar number/VID and authenticate via OTP.
  • Enable the Biometric Lock to prevent all biometric-based authentication.
  • Unlock temporarily or disable the lock anytime when needed for KYC.

3. Generate and Use Virtual ID (VID)

A Virtual ID (VID) is a 16-digit temporary number that you can use instead of your Aadhaar number for KYC. It protects your actual Aadhaar number and reduces risk during verification.

How to generate VID:

  • Visit the UIDAI “VID Generator” page or open the Aadhaar App.
  • Enter your Aadhaar number and authenticate using OTP.
  • Generate a new VID instantly—use this for KYC instead of your Aadhaar number.

4. Enable Aadhaar OTP-Based Authentication

OTP-only authentication prevents biometric misuse and ensures that every verification requires your mobile number linked to Aadhaar.

How to enable:

  • Visit the UIDAI authentication preferences page or the Aadhaar App.
  • Select OTP-based authentication for online KYC.
  • Authenticate using an OTP to save your preference.

5. Check Aadhaar Authentication History

This feature shows where, when, and how your Aadhaar was used in the last 6 months, helping you detect suspicious activity early.

How to check:

  • Open the UIDAI “Authentication History” service or Aadhaar App Activity Log.
  • Enter Aadhaar/VID and verify using OTP.
  • Review all authentication details—date, time, and type of request.
  • If you notice unknown attempts, lock your biometrics immediately and report the issue.

6. Update Your Aadhaar Contact Details

Your mobile number and email must be updated so you receive OTP messages and Aadhaar authentication alerts.

Keep details updated:

  • Visit an Aadhaar Seva Kendra (ASK) to update your mobile or email.
  • Without a valid mobile number, you cannot lock biometrics or receive authentication warnings.

7. Avoid Sharing Aadhaar Unnecessarily

Aadhaar is required for banking, telecom, government schemes, and KYC—but it is not needed everywhere.

How to minimise risk:

  • Use Masked Aadhaar instead of full Aadhaar where possible.
  • Use Offline XML for KYC—this method shares only limited, non-sensitive data.
  • Avoid giving Aadhaar photocopies to unverified agents or shops.

8. Secure Your Devices Before Using Aadhaar Online

Your Aadhaar is only as safe as the device you use.

Device safety tips:

  • Avoid using Aadhaar services on public Wi-Fi.
  • Install an antivirus and keep your phone/computer updated.
  • Avoid downloading unknown apps that request access to files or the camera.
  • Always access Aadhaar services only through the official UIDAI website or the Aadhaar App.

Common Ways Aadhaar Is Misused

Aadhaar misuse usually happens when fraudsters exploit personal data, biometrics, or authentication methods to impersonate an individual. While the UIDAI system itself is secure, Aadhaar can still be misused when users share details carelessly or fall victim to scams. Below are the most common ways Aadhaar fraud occurs today.

1. Biometric cloning using fake devices

Fraudsters illegally replicate fingerprints or face scans to pass e-KYC checks. This can lead to unauthorised banking or SIM-related verifications.

2. Phishing calls pretending to be UIDAI or banks

Scammers ask for Aadhaar numbers, OTPs, or personal details over the phone. They use this information to initiate fraudulent transactions or KYC.

3. Unauthorised SIM cards issued using Aadhaar

Fraudsters use stolen Aadhaar data to activate SIM cards without consent. These SIMs may be used for scams, spam, or illegal activities.

4. Misuse of photocopies of Aadhaar

Shared photocopies can be used for fake registrations or identity theft. Always use masked Aadhaar or secure QR instead of full copies.

5. Fake Aadhaar KYC at cyber cafés or shops

Unverified operators misuse Aadhaar during printing, scanning, or KYC processes. This exposes personal data to unknown third parties.

6. Fraudulent loan applications

Criminals apply for loans using someone else’s Aadhaar and stolen identity details. Victims often realise only after receiving loan recovery calls.

7. Malware stealing Aadhaar details

Malicious apps and infected devices can capture Aadhaar numbers, PDFs, or OTPs. Using official websites and secure devices helps prevent this.

8. Forged Aadhaar cards or manipulated PDF copies

Scammers edit or fake Aadhaar PDFs to impersonate another person. These forged IDs are often used for illegal KYC and registrations.

Frequently Asked Questions on Aadhaar Fraud Prevention

  • Q. Can someone hack my bank account with just my Aadhaar number?

    • No—your Aadhaar number alone cannot access your bank account. Fraud happens only when OTPs, PINs, or biometrics are shared or compromised through scams.

  • Q. Is masked Aadhaar valid for verification?

    • Yes, masked Aadhaar is valid for identity verification and safe to share, as it hides the first eight digits and shows only the last four.

  • Q. What should I do if I notice unauthorised Aadhaar usage?

    • Immediately lock your biometrics, change your Aadhaar App PIN, and report the issue through the UIDAI helpline. Continue monitoring your Activity Log for further attempts.

  • Q. Is Aadhaar mandatory for bank accounts and mobile SIM verification?

    • Aadhaar is not mandatory but is widely used as a convenient KYC document. Banks and telecom providers also accept alternative IDs depending on regulations.

  • Q. Can NRIs use Aadhaar for banking and telecom services?

    • NRIs with Aadhaar can use it for services that require KYC, but NRIs without Aadhaar must use a passport or other valid documents for verification.

  • Q. How do I report Aadhaar misuse to UIDAI?

    • You can report misuse through the UIDAI helpline, email, or by visiting an Aadhaar Seva Kendra. Provide details of suspicious authentication attempts for investigation.

  • Q. Can a leaked Aadhaar photocopy be misused?

    • Yes, photocopies can be misused for fake registrations or identity theft. Always share masked Aadhaar or secure QR codes instead.

  • Q. How can I avoid phishing scams related to Aadhaar?

    • Never share OTPs, Aadhaar numbers, or personal details with callers claiming to be from UIDAI or banks. UIDAI never asks for such information.

  • Q. Can I withdraw money from my Aadhaar card?

    • You cannot withdraw money from Aadhaar itself, but Aadhaar-linked bank accounts allow cash withdrawals at AEPS-enabled centres using biometric authentication.

  • Q. How can I get my lost Aadhaar card?

    • You can download an eAadhaar/Masked Aadhaar from the UIDAI website or the Aadhaar App using OTP. You may also request a reprint if you need a physical copy.
