Why Is the Hong Kong Business Registration Number Also Called the Company Registration Number? A Deep Dive into the Secrets of Hong Kong Company Registration

In the world of entrepreneurship and business operations, many people come across the term company registration number. In Hong Kong, this number is also commonly referred to as the business registration number. Many may wonder why does the same number have two names? And what exactly is its purpose? The answer lies not only in Hong Kong’s legal system but also in the unique corporate management framework that underpins this international financial hub.

1. What Is a Company Registration Business Registration Number?

In Hong Kong, every legally registered company receives a unique identification number - known as the Company Registration Number, or more commonly, the Business Registration Number. This number is issued by the Companies Registry, recorded in the company's official documents, and typically printed on both the Certificate of Incorporation and the Business Registration Certificate.

According to Hong Kong law, any business must be legally registered before conducting commercial activities and must obtain a valid business registration number. This number serves as the company's unique identifier within government systems and is essential for various business functions such as tax filing, opening bank accounts, and signing contracts.

2. Behind the Name Difference History and Institutional Evolution

The terms company registration number and business registration number essentially refer to the same thing. However, business registration number is more frequently used in official documentation and administrative procedures, while company registration number tends to appear in external communications or commercial contexts.

This naming distinction stems from Hong Kong's historical background and legal system. As a former British colony, Hong Kong's corporate registration system was heavily influenced by common law traditions. Under the British legal model, incorporating a company is treated as a registration act rather than an administrative approval process, hence the name business registration number.

Although modern registration processes have become more standardized, the traditional term remains in use. Meanwhile, in practical settings, where clear identification of a company is crucial, more people have adopted the term company registration number due to its functional clarity.

3. The Role of the Business Registration Number More Than Just a Number

At first glance, the business registration number may seem like a simple string of digits, but it plays a vital role throughout a company's lifecycle

1. Corporate Identity Verification

The number acts as the company’s ID number in official systems. It is required during incorporation, annual reporting, deregistration, and when applying for licenses or permits.

2. Tax Compliance and Regulatory Management

The Inland Revenue Department IRD uses the business registration number to identify companies for tax purposes. It is necessary for tax returns, invoicing, and applications for tax refunds.

3. Banking and Financial Services

When opening a corporate bank account, banks typically require the company registration number to verify legitimacy. Similarly, when applying for loans or engaging with financial institutions, the number serves as a key part of credit verification.

4. Commercial Contracts and Partnerships

Including the registration number in contracts clearly identifies the legal party involved, helping to avoid disputes arising from similar or duplicated company names.

5. Public Transparency and Trust Building

Members of the public can look up basic information about a company - including its establishment date, shareholder structure, and whether it is under liquidation - using the business registration number via the Companies Registry website. This transparency fosters trust among clients and partners.

4. How to Obtain a Business Registration Number

To obtain a business registration number, entrepreneurs must follow these steps

1. Determine the Company Structure

Hong Kong allows for various types of businesses, including limited liability companies, unlimited companies, and non-profit organizations. The most common form is the Private Limited Company.

2. Submit Required Documents

These include the company's articles of association, director and shareholder information, registered address, and details of the company secretary. All documents must be submitted through designated channels to the Companies Registry.

3. Receive the Certificate of Incorporation and Business Registration Certificate

Once approved, the company will receive both the Certificate of Incorporation and the Business Registration Certificate, each bearing the unique business registration number.

Thanks to Hong Kong’s streamlined procedures, the entire process can be completed within a single day, reflecting the city’s highly efficient business environment. According to the World Bank’s 2025 Ease of Doing Business Report, Hong Kong consistently ranks among the top jurisdictions globally, with company registration efficiency being a key contributing factor.

5. Recent Developments Digital Transformation in Registration Processes

In recent years, Hong Kong has been actively digitizing its corporate registration procedures. In 2025, the Companies Registry upgraded its online platform, introducing new self-service features such as automated form filling and intelligent feedback systems. These enhancements significantly improved registration efficiency, benefiting startups and foreign investors alike.

Additionally, in early 2025, Hong Kong announced plans to pilot blockchain technology in enterprise registration, aiming to enhance data security and transparency. In the future, the business registration number could evolve beyond a static ID into a dynamic key linking all aspects of a company's lifecycle data.

Conclusion
