Mr. Darshan has given you the correct reply. The Date of Joining in EPF & EPS means from which date he got enrolled in EPF and not on the company's roll. If a person joins the company in 2005 and the company strength of employees reaches to 20 in 2010, then the date of Joining in EPF & EPS should be shown as 2010 date and not 2005 date. Hope your doubt got cleared.
