HK D-U-N-S Number Application All Details You Need to Know

A Comprehensive Guide to Applying for a D-U-N-S® Number in Hong Kong

In the context of global economic integration, the importance of corporate credit information has become increasingly evident. As an internationally recognized business identification system, the D-U-N-S® Number issued by Dun Bradstreet has become essential for many companies operating in international markets. Particularly for businesses planning to expand overseas, participate in international tenders, or collaborate with multinational corporations, obtaining a D-U-N-S® Number is more important than ever.

1. What is a D-U-N-S® Number?

A D-U-N-S® Number is a unique nine-digit identifier assigned by Dun Bradstreet, a U.S.-based commercial data service provider. This number remains unchanged regardless of modifications to a company’s name, address, or other details, ensuring its global uniqueness and permanence. It is used across more than 200 countries and regions as a key index for tracking business credit records, operational performance, and compliance.

In recent years, with the rapid growth of cross-border e-commerce, international trade, and supply chain finance, more and more companies based in mainland China and Hong Kong have begun to value the application and use of this number. Starting in 2025, several major e-commerce platforms-including Alibaba.com and Amazon B2B-have required suppliers to register for a D-U-N-S® Number to enhance transaction transparency and security.

2. Why Apply for a D-U-N-S® Number in Hong Kong?

As one of Asia’s most internationalized financial hubs, Hong Kong has long served as a gateway for enterprises expanding globally. Compared to applying through mainland China, registering a D-U-N-S® Number under a Hong Kong company offers several distinct advantages

1. Efficient Review Process In contrast to the stricter verification procedures in certain parts of mainland China, documents submitted via Hong Kong companies are generally easier to validate through the Dun Bradstreet system.

2. Broader Applicability Companies with a D-U-N-S® Number linked to a Hong Kong entity can more easily establish partnerships with European and American clients, especially in export trade and offshore operations.

3. Facilitates Cross-Border Operations If your business plans to set up overseas branches or pursue financing in the future, having an internationally recognized D-U-N-S® Number significantly enhances credibility and professional image.

4. Low Maintenance Cost Once obtained, the number does not require annual renewal or regular updates unless there are significant changes to company information, making it easy to manage.

3. Who Should Apply for a D-U-N-S® Number?

While obtaining a D-U-N-S® Number is not mandatory for all businesses, it is strongly recommended in the following scenarios

Export-oriented companies planning to participate in international exhibitions or bidding projects;

B2B sellers on online marketplaces such as Amazon, eBay, and Alibaba.com;

Small and medium-sized enterprises SMEs seeking collaboration with large multinationals;

Companies considering cross-border investments or fundraising;

Exporters required to provide credit credentials to clients.

According to recent media reports, during the first quarter of 2025, many mainland Chinese companies were disqualified from international procurement opportunities due to the lack of a D-U-N-S® Number. Therefore, preparing relevant credentials in advance has become a fundamental step in enterprise globalization.
