How Date of Birth (DOB) in Aadhaar can be verified ?

DOB in Aadhaar shall be marked as verified when a valid proof of birth document is submitted at the time of enrolment or update. You are requested to ensure that the operator selects 'verified' option for DOB. Only year of birth (YOB) shall be printed on your Aadhaar Letter if the DOB is marked as 'declared' or 'approximate'.
