Company Identifiers

  • BRN (Business Registration Number): The unique 8-digit identifier for Hong Kong companies (e.g., 77054426).
  • CI Number (Certificate of Incorporation): A different identifier - not used by our API.
Always use the BRN (Business Registration Number) when searching or requesting company data. The CI Number is a separate identifier and will not work with our endpoints.

​
Search Behaviour

  • By BRN (8 digits): search("77054426") - Returns the specific company
  • By company name: search("Technology Advantage") - Returns companies matching the name (prefix match)
