For Employees’ Provident Fund (EPF) subscribers, maintaining updated Know Your Customer (KYC) details on the Universal Account Number (UAN) portal is crucial for accessing various EPFO services, including online PF withdrawal and account transfers. KYC requires linking identity and financial documents like Aadhaar, PAN, and bank account details to the UAN for verification. The article provides a detailed step-by-step guide for updating KYC online, emphasizing the need for accurate information to avoid verification issues. Before starting the update process, users should have their UAN number, password, Aadhaar-linked mobile number, PAN card, and bank account details ready. Common pitfalls to avoid include mismatches in names, incorrect PAN entries, and inactive mobile numbers linked to Aadhaar. After submitting KYC updates, users can track their status on the UAN portal, which can be Pending, Verified, or Rejected. Given the increasing reliance on Aadhaar for EPF claims, ensuring its correct linkage is essential for smooth processing of withdrawal or transfer requests.
