What Is A Business Registration Number (BRN) In Hong Kong?
A Business Registration Number (BRN) is a unique 8-digit identifier issued by the Business Registration Office under the Inland Revenue Department (IRD). It allows businesses to be officially distinguished from one another and serves as proof of legal recognition in Hong Kong. The BRN is essential for tax administration, regulatory compliance, and conducting official business transactions, making it a cornerstone of Hong Kong’s business ecosystem.
It is important to note that the BRN is different from a Company Registration Number (CRN). While a CRN is primarily used to identify incorporated companies for legal purposes, the BRN focuses on tax-related and regulatory identification for all types of business entities, including sole proprietorships, partnerships, and foreign companies operating locally. A significant update came into effect on 27 December 2023, when the BRN was designated as the Unique Business Identifier (UBI) for all businesses in Hong Kong. This change aims to streamline business identification across government departments, making the BRN the standard reference number for official transactions and communications with authorities.
Advantages of Having a Business Registration Number
Obtaining a Business Registration Number (BRN) is not just a legal requirement, it also offers numerous advantages that help businesses operate efficiently. Here’s why having a BRN is essential:
1. Filing Annual Returns Easily
A BRN streamlines the submission of annual returns to the Inland Revenue Department (IRD). With this unique identifier, businesses can quickly file tax documents, reducing administrative delays and ensuring timely compliance with Hong Kong’s tax regulations.
2. Legally Conducting Business Transactions
Whether signing contracts, opening bank accounts, or engaging in trade, a BRN is a mandatory reference for all official transactions. It ensures that your business operates legally and avoids potential disputes or penalties related to unregistered activities.
3. Establishing Credibility with Partners and Customers
Displaying a BRN on your Business Registration Certificate and official communications signals professionalism and regulatory compliance. This builds trust with clients, suppliers, and investors, positioning your business as a legitimate and reliable entity in Hong Kong.
4. Accessing Government Services and Incentives
A valid BRN allows businesses to access a variety of government services, benefits, and incentives, such as funding programs, licensing approvals, and trade facilitation schemes. It acts as the gateway to resources that support business growth and expansion.
5. Ensuring Compliance with Hong Kong Laws
By obtaining a BRN, businesses meet the mandatory requirements of the Companies Ordinance and the Business Registration Ordinance. This reduces legal risks, ensures smooth audits, and safeguards your business from regulatory penalties.
Who Needs A Business Registration Number?
In Hong Kong, obtaining a Business Registration Number (BRN) is mandatory for most businesses. The BRN not only ensures legal compliance but also enables smooth interactions with government authorities, financial institutions, and partners.
Types of Businesses Required to Register
- Sole Proprietors – Individuals running a business under their own name must register for a BRN to operate legally.
- Partnerships – Partnerships, whether limited or general, require a BRN for taxation and regulatory purposes.
- Limited Companies – Both private and public limited companies incorporated in Hong Kong must obtain a BRN alongside their Company Registration Number (CRN).
- Freelancers and Self-Employed Individuals – Solo practitioners offering services generally need to register to ensure legitimacy and compliance with tax laws.
Exempted Activities
Certain activities are exempt from registering a Business Registration Number such as:
- Agriculture and market gardening
- Breeding and rearing livestock
- Fishing
- Charitable work
These exemptions generally apply to non-commercial or small-scale community-based activities.
Importance of Compliance for Local and Non-Hong Kong Companies
Both local and foreign companies with business operations in Hong Kong must comply with Business Registration Number requirements. For non-Hong Kong entities, a BRN ensures proper tax registration and enables participation in legal transactions. Compliance protects businesses from fines and legal disputes while also establishing credibility with clients, suppliers, and government agencies.
Business Registration Number Format
In Hong Kong, a Business Registration Number (BRN) is always a unique eight-digit number that identifies your business for tax and regulatory purposes. It is a critical element for compliance and smooth operations.
Eight-Digit Unique Number
The BRN follows a simple numeric format without any letters, symbols, or prefixes. Examples include:
- 12345678
- 87654321
Each number is unique to the business and ensures that it can be distinguished from all other registered entities in Hong Kong.
How the BRN Is Derived
The BRN is generated by the Inland Revenue Department (IRD) and is essentially the first eight digits of the Business Registration Certificate number. When your business registers with the IRD, this number is automatically assigned and printed on your certificate, serving as your official business identifier.
Examples for Local vs. Foreign Companies
The format remains consistent for all types of businesses, whether local or foreign:
- Local Company: A limited company providing consultancy services might have a BRN like 23456789.
- Foreign Company: A non-Hong Kong company operating an import-export business in Hong Kong could have a BRN such as 98765432.
This standardization ensures ease of verification, tax compliance, and legal recognition across all government departments and financial institutions.

Differences Between Company Registration Number (CRN) and Business Registration Number (BRN)
Understanding the difference between a Company Registration Number (CRN) and a Business Registration Number (BRN) is essential for operating a business legally in Hong Kong. Both numbers serve distinct purposes and are issued by different authorities, yet they are equally crucial for compliance, banking, and other official transactions.
CRN vs BRN Comparison Table
| Aspect | Company Registration Number (CRN) | Business Registration Number (BRN) |
| Purpose | Official company ID for government recognition and legal compliance | Identifier for tax purposes, issued by the Inland Revenue Department |

Why Both Numbers Are Essential

- Banking and Financial Transactions: Both numbers are typically required when opening bank accounts or applying for business loans in Hong Kong.
- Official Documentation: Government departments and partners may request both CRN and BRN for licensing, permits, and contractual agreements.
- Streamlined Operations: Having both numbers ensures your business can operate efficiently, avoid legal complications, and be fully recognized by authorities.
