Third Party Software Interface Specification

The Third Party Software Interface ("TPSI") Specification is designed for reference by software developers and in-house IT professionals of our customers ("software developers") who are providing software and/or services to their clients who are engaged in company formation and/or filing of company documents in Hong Kong.

Latest Updates

To facilitate the implementation of Phase 2 of the new inspection regime of the Companies Register under the Companies Ordinance (“New Inspection Regime”), the Registrar of Companies has revised the specified forms which pertain to the reporting of Protected Information for use starting from the implementation date (i.e. 24 October 2022).  For e-Registry, the support for submission of ten electronic forms which contain Protected Information (NAR1, ND2A, ND2B, ND4, ND5, ND7, ND8, NNC1, NNC1G and NN3) through TPSI has been suspended from 24 October 2022. Registered users of the e-Registry may still submit the aforesaid ten forms through the “Online Submission” service at the e-Registry.  Meanwhile, the support for submission of the other three forms which do not contain Protected Information (NNC2, NR1 and NSC1) through TPSI will continue.  For details of the New Inspection Regime and revisions to specified forms, please refer to the thematic section on “New Inspection Regime” on this website and the Companies Registry External Circular No. 1/2022 issued on 24 June 2022 respectively.
