This document is a Joint Declaration Form used to correct personal details such as name, date of birth, or gender associated with an Employee Provident Fund (EPF) Universal Account Number (UAN). It's required when online modifications are not possible due to reasons like a changed mobile number or unlinked Aadhaar. The form needs to be filled out jointly by the employer and employee, supported by relevant documents like Aadhaar, and submitted to the Regional PF Commissioner. This is useful for any EPF member needing to rectify their official records.
