The statutory identifiers for this corporation issued by Hong Kong SAR authorities are: 1.

In international banking KYC, trade bills of lading, and cross-border contracts, these two numbers uniquely confirm entity legitimacy.

Under Hong Kong law, incorporated companies do not maintain a 'legal representative' position; the Board of Directors exercises supreme statutory management authority. Under the New Inspection Regime of the Companies Ordinance, public inspection protects directors' personal identification by displaying correspondence addresses and masked ID numbers. To inspect certified directorship history, shareholding structure (Form NAR1), Significant Controllers Register (SCR), and multi-tier beneficial ownership (UBO), formal certified registers must be retrieved through statutory registry inspection or corporate due diligence procedures.
