Registration is the process by which every employer/factory and its every employee employed for wages, is identified for the purpose of the Scheme, and their individual records are set up for them. ESI registration applies to all factories or entities that employ 10 or more persons who have a maximum wage of Rs. 21,000. However, in some states, it is 20 employees. ESIC is the only Social Security Organisation in the country which covers most of the exigencies (provided in the list of ILO) which are sickness, medical care for the worker, maternity, unemployment, work injury, death of worker, invalidity and widowhood.
