Linking your Aadhaar with your mobile number has become one of the most important updates in 2025 as government services, banking systems, financial apps and KYC processes increasingly depend on Aadhaar-based verification. With the latest digital improvements, UIDAI now offers a simplified system that helps residents complete the mobile linking process more efficiently. Having your mobile number updated with Aadhaar ensures that you receive OTPs, notifications and verification alerts for essential services without any interruption.
Why Linking Aadhaar with Your Mobile Number Is Important
A mobile number linked with Aadhaar is required for online banking, PAN updates, income tax filing, subsidy verification, e-KYC for SIM activation, digital wallet usage and accessing government schemes. Most Aadhaar-related services rely on OTP-based authentication, which means an unlinked mobile number can prevent you from completing important updates. Linking your number helps secure your identity, prevents misuse of your Aadhaar details and ensures seamless access to all digital services.
How the Online Linking Process Works
UIDAI has refreshed the linking system so that residents can begin the process online and complete it through an authorized Aadhaar service point. Users must start by visiting the Aadhaar Self-Service Update Portal, entering their Aadhaar number and submitting the request for mobile linking. An SRN is generated, after which residents are required to verify their identity at an Aadhaar Seva Kendra or partner center using biometrics. Once verified, the mobile number is successfully updated in the UIDAI database, enabling the user to access all Aadhaar-based online services.
What You Need Before Linking Your Number
To begin the process, users must have their Aadhaar number, a valid mobile number they want to link and a proof of identity when completing biometric verification. Those who already have a linked number but want to update it can also follow the same method. The system ensures that only the rightful Aadhaar holder can update or change the mobile number, offering complete security during the process.
How Long the Update Takes
After the biometric verification is completed, UIDAI usually activates the updated mobile number within a few working days. Users receive an SMS from UIDAI confirming the successful linking. Once linked, the number becomes eligible for all OTP-based authentications on the Aadhaar platform, allowing smooth access to all government and banking services.
What to Do If Your Mobile Number Is Not Working
If the old mobile number linked with Aadhaar is inactive or lost, you can still update your Aadhaar by visiting an Aadhaar Seva Kendra for biometric authentication. Only a physical visit is allowed in such cases because UIDAI must validate the identity of the user to prevent unauthorized updates. After linking the new number, all Aadhaar services can be accessed online without further visits.
Conclusion: Linking your Aadhaar with your mobile number in 2025 is an essential step to ensure uninterrupted access to digital services, government schemes and secure identity verification. The updated UIDAI process makes it easy for residents to initiate the linking request online and complete verification quickly. Keeping your mobile number up to date ensures smooth KYC approvals, secure OTP logins and seamless use of Aadhaar-enabled services across the country.
