I worked for a company in Hyderabad for 7 years and 3 months before moving to Chennai and joining a new company. I transferred my PF, but HR assigned me a new UAN number instead of using the old one I provided. After a year in Chennai, I started working at my current company in Pune, where I have been for the past 3.5 years. Recently, I noticed that the EPS amount has not been transferred, and it seems unlikely to have been transferred. To secure my EPS benefits, do I need to take any action, such as obtaining a scheme certificate? My total work experience is 12 years, and I withdrew PF from the previous two companies but am uncertain if I received EPS benefits. Additionally, what steps should be taken if the service period is less than 5 years, as in the case of my brother who has a different UAN from his old company and is still employed in a new one?
