Firm Registration Number (FRN)

Firm Registration Number (FRN) is a unique identification number allotted to a chartered accountant firm by the Institute of Chartered Accountants of India (ICAI).

It is used to identify and track the firm for regulatory, compliance, and professional purposes.

What this really means

When a CA firm is registered with ICAI, it is assigned an FRN. This number acts like an official identity for the firm.

It is required whenever the firm:

• Conducts audits
• Signs reports
• Files documents with authorities
• Communicates in a professional capacity

Who Issues FRN?

FRN is issued by:

👉 The Institute of Chartered Accountants of India (ICAI)

Only firms registered with ICAI are eligible to receive this number.

Where is FRN Used?

FRN is commonly used in:

• Audit reports and certificates
• Financial statements and compliance filings
• Peer review and quality review processes
• Communication with regulatory authorities
• Professional documentation and records

Why FRN is Important

FRN establishes the authenticity and identity of a CA firm.

It helps:

• Verify that the firm is registered with ICAI
• Ensure accountability in professional work
• Maintain transparency in audit and assurance services
• Track compliance and regulatory requirements

FRN vs Membership Number

This is a common confusion:

• FRN (Firm Registration Number)
  • Issued to CA firms
• Membership Number
  • Issued to individual Chartered Accountants

Both are important but serve different purposes.

Important Points to Remember

• FRN is mandatory for practicing CA firms
• It must be quoted in audit reports and professional work
• It is issued only after registration with ICAI
• It helps in regulatory tracking and compliance
