Dear Madhura,
After full compuerization of the scheme, Insured Person can add their family members by submitting the required application at the branch office. IP has to attend to Branch Office alongwith the pending family members, there ESIC will capture the particulars and finger prints of such additional family members.
Before computerisation, if u want to add ur family members, u can add the family members in the manual card, which will serve the purpose of getting medical care to the IPs family members.............
For further guidance, please approach the nearest ESI Branch Office.....
