CIN is issued from Ministry of Corporate affairs, and by default at the time of company registration it sends data to shramsuvidha, to issue LIN and when applicable it issues EPF and ESIC codes respectively
once the establishment exceeds the manpower threshold limit in EPF or ESIC, it will help the establishment to get registration smoothly.
As companies registered on the portal of MCA have to make compliance of all respective labor laws, shramsuvidha is unified portal for all compliances in single place
