Enrolment & Update

No, it is not mandatory to provide a mobile number or email id for Aadhaar enrolment of Resident Indian (email is mandatory for NRI and Resident Foreign National).
But it is always recommended to provide a mobile number and email id so that you get updates regarding your Aadhaar application status and can get a number of services based on Aadhaar through OTP-based authentication.

Aadhaar has an inclusive approach and its enrolment/ update processes are accessible to all including persons with disabilities. The Regulation 6 of Aadhaar (Enrolment and update) Regulations, 2016 provides for enrolment of individuals with biometric exceptions, which inter-alia lays down that:

1. For Individuals seeking enrolment who are unable to provide fingerprints, owing to reasons such as injury, deformities, amputation of the fingers/ hands or any other relevant reason, only Iris scans of such individuals will be collected.
2. For Individuals seeking enrolment who are unable to provide any biometric information contemplated by these regulations, the Authority shall provide for handling of such exceptions in the enrolment and update software, and such enrolment shall be carried out as per the procedure as may be specified by the Authority for this purpose.
