How to link Aadhaar card to Voter ID card?

You can link your Aadhaar card to your Voter ID by submitting Form 6B through the official Voter Service Portal (voters.eci.gov.in) or the Voter Helpline App. Log in, select Form 6B, enter your EPIC and Aadhaar numbers, and verify using the OTP sent to your Aadhaar-linked mobile number. Alternatively, you can link them via SMS by sending ECILINK to 166 or 51969. For offline linking, submit a physical Form 6B to your local Booth Level Officer (BLO). This process is voluntary and free of cost.
