Curious About EPFO's UAN Services? How Do We Register and What's the Purpose?

I want to know about Universal Account Number Services started by EPFO. When we went through the site, we came to know about these services, but I want detailed information about these services. Why are these services provided? How do we register ourselves? What are they meant for, in terms of the purpose of these services? Because when we click on "register your name for attending training session," a message displays:

Nomination for UAN Training

1st Session
Friday - 18th July - 3 PM to 5 PM CLOSED

2nd Session
Saturday - 19th July - 11 AM to 1 PM CLOSED

3rd Session
Saturday - 19th July - 3 PM to 5 PM CLOSED

Select your Session:

Select your EPF Office:

Establishment Code:

Establishment Name:

No. Name Designation Mobile Number Email
1.
2.

* NOTE:
  1. Maximum two (2) persons can be nominated per establishment.
  2. EPFO is only conducting the training session. Participants are to make their own travel and stay arrangements at their own cost.

Does it mean that we have to take training individually? If it's not possible for anyone, what should he/she do?

Sir, I have submitted all KYC for the Universal Account Number Services started by EPFO in Version-I. Now EPFO has updated to Version-II. Is there a need to submit KYC again? In Version-II, only AADHAR and PAN Verification for members are required, but there is no information about submitting any other documents for KYC.

Is it only submitted or verified digitally as well? If verified digitally, ask members to check the same from their member portal login; it would be present there.
