Labour Identification Number: Is EPF/ESIC registration now merged?

I am about to take EPF Code and ESIC Code for my firm. I came across the LIN number initiative of Shram Suvidha Portal. Please confirm if i need to take those registrations separately or just LIN no is to be taken. The Portal is not working as registration is process is not moving forward due to OTP error. Kindly throw some light on the matter. Thanks.

u need to take both registrations separately, on individual portal, as on shram suvidha portal combined registration process is not working.
