  • The ID does not contain alphabetic or special characters.
  • The ID consists of three groups of four numbers, with a space separating each group of four.
  • The ID does not start with either a "0" or "1".

Configure the Candidate information layout on the Collect personal details Step to display a field for the Aadhaar ID. Configure the form so that the field is displayed and is required only if the user selects country as India (IND).
