Explanation:

The Universal Account Number is a scheme to make the Employee Provident fund portable.
UAN refers to the Universal Account Number introduced by EPFO India. It is a unique 12-digit number assigned to an employee by EPFO India. The EPFO UAN number will act as a marker of identity for an employee till his/her retirement. In order to generate a UAN number, an employee needs to be registered with EPFO services and should contribute to the Employee Provident Fund Account. The major motive behind the launch of UAN is to link multiple PF account numbers allotted to a single employee by different organizations under one single account.
