LIN registration

I would like to register for ESIC but when I am doing through Shram Suvidha there is showing that LIN is mandatory registered but I cannot. Tell anyone the registration procedure . it will be help for me. thanking you.

Very simple proceedure. Open their website (Shram Suvidha) and fill in their questionnaire (registering details ) correctly. LIN will be notified on your system as well as in your mobile no.
LIN is now mandatory.
