Dear Mr Rao
sir, Can you help me on this?
Is it necessary to have separate sub unite code, in case of factory or establishment working in multiple city or state?
if we need to take separate sub unit code in case of above mention query, is there any circular or section under ESIC Act ??
if we operate with centralize code, will it hit our compliances
please help on this.....
