Hi, I have been working since 2010 and I have a UAN number. I used it until 2016. In September 2016, when I joined another company, they, unfortunately, allotted another UAN number which I used until 2020. When I joined my current company in 2020, instead of using the latest UAN since I was unaware of the rule, I gave them the first UAN, and they are using the first UAN. Recently, I came to know that the latest UAN should be used; however, I'm using the first UAN in my current company and the second UAN is dormant. Please suggest what I should do.
