I am Gayathri. Today i faced one EPF related issue. Today i tried to Allot UAN for an Employee. But when i put the Employee Details in EPF Portal it shows UAN ---------------- is already allotted like that. But employee says, i haven't any UAN and EPF No. In this situation what i have to do and how to tackle this problem?
