Go to the EPFO website, then click on Establishment Search. Provide the required information. Once you locate your establishment, you will find the Region Code, Office Code, Establishment Code, and Establishment Extension. Note these down on a piece of paper. Proceed to click on the last column labeled payment, where you will find details of payments made for all employees. Click on the "No. of employees" column to access a list of all employees in your establishment. Look for your name, and the Sr. No. will be your employee code.
