What Is a Business Registration Number (BRN) and Why Is It Important?
- Published: 19 January 2026
The Business Registration Number (BRN) is an eight-digit identifier issued by the Inland Revenue Department (IRD) that establishes your company’s legal identity in Hong Kong. It is included on the Business Registration Certificate (BRC) and serves as the company’s Tax Identification Number (TIN). Osome ensures your BRN is issued correctly and incorporated into your official documentation immediately upon company registration.
