Department Functionality and Aadhaar Requirement
AADHAAR was not initially implemented across the whole of India; only a few states had it in the beginning. Now, enrollment has been extended to other states as well. Keeping this in view, it was absolutely absurd on the part of EPFO to seek AADHAAR Cards, especially on a mandatory basis. By the time they realized this, the notification had already been removed.
After some time, they put this requirement on hold. The bottom line is that the submission of AADHAAR Cards is not mandatory. However, those who have it must submit it to their employers during joining, leaving, or settlements.
