@pipeworx/hk-companies

Hong Kong Companies Registry (香港公司註冊處) open data — a live feed of companies newly incorporated, registered, or renamed on the register, with a name/BR-number search and an HKEX ticker join.

Data source — verified live 2026-09-07

The Companies Registry's open-data landing page (cr.gov.hk/en/open-data/) is 404 and data.gov.hk's own HTML dataset listing is client-rendered (zero s in the page source), so the real resource URLs come only from data.gov.hk's CKAN-style API, found via its org slug for the Registry:

https://data.gov.hk/en-data/api/3/action/organization_show?id=hk-cr
https://data.gov.hk/en-data/api/3/action/package_show?id=hk-cr-crdata-list-newly-registered-companies-2526

That package lists ~350 weekly CSV resource pairs, one per week since 2024-12-30:

local companies (newly incorporated / re-domiciled / renamed)

• https://www.cr.gov.hk/docs/wrpt/RNC063/RNC063L_YYYYMMDD.csv — Hong Kong

Kong companies (newly registered / re-domiciled / renamed)

• https://www.cr.gov.hk/docs/wrpt/RNC063/RNC063F_YYYYMMDD.csv — non-Hong

YYYYMMDD is the Monday of the covered week; each file covers that Monday through the following Sunday. Publication runs roughly a week behind (the 24-30 Aug 2026 week was published 2 Sep).

This pack fetches the live resource list from packageshow on every call (no guessed URL pattern), then only fetches the CSV weeks that can contain a match, in parallel, bounded to 20 weeks per company type per call so one request can't fan out into hundreds of upstream fetches. hkcompanysearch and hkcompany default to a 12-week lookback unless since is given (as far back as 2024-12-30, the dataset start); hknewcompanies and hkcompanyname_changes default to the 7 days before the latest published week.

CSV shapes (they differ — verified from a live fetch of both)

Local (RNC063L): Seq, Current Company Name in English, Current Company Name in Chinese, BR Number, Date of Incorporation / Re-domiciliation Date, Date of Change of name — English and Chinese are already separate columns.

Non-HK (RNC063F): Seq, Current Corporate Name / Other Corporate Name, Current Approved Name for Carrying on Business in H.K., BR Number, Date of Registration, Date of Change of name — there is no separate Chinese-name column. A non-HK company with both an English and a Chinese name gets two physical rows sharing the same BR number and Seq, one name per row in the single "Current Corporate Name / Other Corporate Name" column. This pack merges those pairs by BR number (routing CJK text to namezh, everything else to nameen) rather than surfacing them as two different companies.
