You cannot directly check the full mobile number linked to Aadhaar online
Visit the UIDAI website or mAadhaar app to verify if your mobile number is linked
Use the Aadhaar authentication or OTP service to test the registered mobile number
If OTP is received on your mobile, it is linked to Aadhaar
If no OTP is received, the mobile number may not be linked or may be outdated
Visit an Aadhaar Enrolment/Update Centre to confirm or update the mobile number
Carry your Aadhaar number and valid identity proof when visiting the centre
You can also call UIDAI helpline 1947 for guidance
For security reasons, only the last few digits of the linked mobile number may be shown in some services
