Primary ESIC Code for Main Establishment

• Every firm receives one main ESIC code upon its first registration.
  
• This 17-digit code is unique to the principal or head office location.
  
• It serves as the primary identifier for the employer under the ESIC Act.
  
• All compliance and contributions for that location are filed under this code.
  
• The main code is essential for organizational-level registration.
  

Use of Sub-Codes for Branches

• Firms operating in multiple locations can obtain sub-codes for each branch.
  
• Sub-codes are linked to the main ESIC code for administrative tracking.
  
• Each branch can manage its own employee list and compliance separately.
  
• Sub-codes ensure that regional operations remain compliant independently.
  
• The main office remains responsible for overall oversight and coordination.
  

Conditions Requiring Multiple Codes

• If a firm opens a new unit in a different state or ESIC region.
  
• When employee records and compliance need to be maintained locally.
  
• If a branch is functioning as a distinct operational unit.
  
• If directed by ESIC authorities based on administrative convenience.
  
• For establishments engaging in multiple business activities at separate sites.
  

Procedure for Obtaining Additional Codes

• The firm must apply online for sub-code allotment using the employer portal.
  
• Details of the new branch including address and employee data must be submitted.
  
• Documentation proving the branch’s existence and operations is required.
  
• The system processes and issues a separate sub-code under the main employer code.
  
• Separate login credentials may be generated for each sub-code holder.
  

Compliance and Responsibility Across Codes

• Each ESIC code or sub-code has its own compliance obligations.
  
• Monthly returns, contributions, and employee records must be maintained per code.
  
• The principal employer remains responsible for overall legal compliance.
  
• Changes in workforce, wages, or location must be updated under each code.
  
• Proper coordination ensures smooth inspections, audits, and benefit claims.
