When linked with vital identification tools like the Aadhar card in India, they play a pivotal role in ensuring seamless and secure access to a multitude of services. Below, we delve deeper into the manifold significance of having a valid mobile number registered with Aadhar:

#1. OTP-Based Authentication:

Secure Transactions: The majority of online transactions, whether it’s a bank transfer or any governmental service application, require an OTP (One-Time Password) verification. This OTP is sent to the registered mobile number, acting as a two-factor authentication method.

Reduction of Fraud: By demanding OTP verification, unauthorized access or fraudulent activities can be significantly reduced, ensuring only the Aadhar card holder can undertake the transaction.

#2. Aadhar Services Access:

  • e-KYC: Know Your Customer (e-KYC) is a process used by service providers to verify the identity of their customers. The Aadhar-linked mobile number facilitates instant e-KYC, speeding up procedures like SIM card purchases, bank account openings, and more.
  • Downloading e-Aadhar: If you need a digital copy of your Aadhar, it can be downloaded using an OTP sent to your registered mobile number, ensuring secure access.
  • Aadhar Updates: Making any online changes to your Aadhar card data requires an OTP authentication, which is sent to your registered mobile number.

#3. Notifications & Alerts:

  • Governmental Communications: The government often rolls out schemes and benefits related to Aadhar. Having a registered mobile number ensures you don’t miss out on important notifications.
  • Transaction Alerts: Any Aadhar-based transaction or authentication process will trigger an alert to the registered mobile number, keeping you informed and adding an extra layer of security.

#4. Convenience in Service Access:

Telecom Services: For buying new SIM cards, telecom service providers now mandate Aadhar-based e-KYC, which uses the registered mobile number for OTP verification.

Utility Registrations: For utilities like gas connections or electricity, Aadhar-based registrations are streamlined and often mandate OTP verifications.

#5. Feedback Mechanism:

Discrepancy Alerts: In case of any inconsistencies or unauthorized usage of one’s Aadhar, alerts are sent to the registered mobile number. This facilitates timely intervention and corrective action.

Service Satisfaction Surveys: Sometimes, after availing of a service related to Aadhar, feedback OTPs or links might be sent to the registered mobile number, ensuring a feedback loop.

#6. Mandatory For Online Platform Use:

  • UIDAI Online Services: Several online services provided by UIDAI, like checking the status of an Aadhar application, raising a complaint, or updating personal details (excluding mobile number), require OTP verification.
  • Governmental Portal Access: Various government portals that require Aadhar linkage, like the DigiLocker, also depend on the OTP sent to the registered mobile number for authentication.


Keeping your Aadhar details, especially your mobile number, up to date is of utmost importance. The process, while necessitating a physical visit for mobile number updates, is streamlined and simple. Ensure you always have a valid mobile number registered with Aadhar, enabling seamless access to various services.
