The Universal Account Number (UAN) is provided to all Employee Provident Fund (EPF) account holders. All your Provident Fund account (with different employers) will come under the same UAN. Your employer will provide you with the UAN number. If not, go to http://uanmembers.epfoservices.in/check_uan_status.php. Fill in your EPF details and check the status of your UAN. Once your UAN has been allotted, you need to activate it in order to use it. If you are unemployed but want a UAN, go to the EPF website to register for UAN. You can use your UAN number to check your EPF account balance and apply for withdrawals.
