Greetings to all. I have recently joined as an HR professional in a company. The issue I found here is that some of the employees were transferred to different units of the same company around one year back, i.e., in 2016. They were shown as "left" from this unit and given new joining in another unit. They have UAN numbers initially issued by the company, but when they joined the new unit, they were issued a different UAN number (either by the mistake of the HR person or by the EPFO office). Now, I want to know how these both UAN numbers can be merged, or if one can be stopped. Will it be done by submitting Form 13 (revised), or is there any other process?
