This number usually appears on

These platforms aggregate official data and offer enhanced search features, multilingual interfaces, and batch query options-ideal for enterprise users. However, be aware that third-party data may not always be up-to-date, so always verify against official sources.

According to a July 2025 report by the South China Morning Post, as cross-border investment and collaboration between mainland China and Hong Kong increase, more mainland companies are strengthening their verification of Hong Kong company registration details before signing agreements. Especially for projects involving large sums of money or intellectual property rights, companies prefer to obtain verified information directly from official channels to mitigate risks.

The Companies Registry has also improved its online services. In May 2025, the agency announced an upgrade to the eSearch platform, adding a Chinese interface, smart search suggestions, and other enhancements to improve user experience.
