What is the primary feature of the EPF’s universal account number (UAN)?

The primary feature of the EPF's universal account number (UAN) is its ability to allow employees to manage multiple EPF accounts using a single UAN. The UAN serves as a unique identifier for an employee's EPF accounts, facilitating the portability of these accounts when an employee changes jobs or employers. This means that rather than having to manage separate account numbers for each employer, the employee can consolidate their EPF savings under one UAN. This system simplifies the process of tracking retirement savings and ensures that employees do not lose track of their contributions and balances in various EPF accounts. By consolidating these accounts, the UAN enhances the manageability and transparency of the employee's retirement fund, making it easier for them to access their funds and check their balance online.
