registration of labour identification number (lin)

Know Your LIN

1) Each establishment will be allotted a Unique Labour Identification Number (Shram Pehchan Sankhya).

2) Check your LIN at Shram Suvidha portal.

3) Existing establishments who are registered with EPFO or ESIC do not need to register separately for allotment of LIN.

From the data existing at EPFO or ESIC for an establishment, LIN would have been created. In case an establishment has not received the Login credentials, they may contact their regional Unified Web Portal (UWP) head.

4) In case, an unit/establishment has already been allotted a LIN, they can verify the information associated with LIN at the shram suvidha portal and update it, if needed.

5) For employers, who do not have any existing registrations, they can register at shram suvidha portal for allotment of LIN.
