Visit the UIDAI website and use the “Verify Email/Mobile Number” service
Enter your Aadhaar number and the mobile number you want to check
If the number is linked, the verification will confirm it
If you do not know the linked number, visit an Aadhaar Enrolment/Update Centre
Carry your Aadhaar card and a valid ID proof
Ask the centre to check the mobile number linked to your Aadhaar
You can also call UIDAI helpline 1947 for guidance
Use the mAadhaar app if your mobile number is already registered and accessible
No online public service shows the full linked mobile number directly for privacy reasons
