The EPF registration process involves: 

Employer Registration: Employers need to register themselves with the EPFO. This involves submitting various documents such as the establishment's registration certificate, address proof, PAN card, etc.

Employee Enrollment: Once the employer is registered, they need to enroll their employees for EPF. Each employee is assigned a unique EPF account number.

Contributions: Both the employer and the employee make monthly contributions to the EPF scheme. The employer deducts the employee's contribution from their salary and contributes its share as well. These contributions are deposited into the employees' EPF accounts.

EPF Returns: Employers are required to file monthly EPF returns providing details of contributions made by both the employer and the employee.

EPF registration is mandatory for all establishments with 20 or more employees. It provides various benefits to employees such as retirement savings, partial withdrawals for specific purposes like housing, medical emergencies, education, etc., and pension benefits after retirement.
