How to link Aadhaar card to mobile number at home

To link your Aadhaar card to a mobile number from home, you can use the India Post Payments Bank (IPPB) doorstep service. Visit the official IPPB website, navigate to the Service Request section, and select Doorstep Banking. Choose the Aadhaar-Mobile Update service, fill in your personal details, and submit the request. A postman will visit your home to complete the biometric authentication and link your number for a nominal fee of Rs. 50 plus GST. Note that initial mobile linking cannot be done entirely online via the UIDAI portal.
