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.

Tools

• hk_company_search({ name?, brn?, type?, since?, limit? }) — search by company name (English or Chinese, substring) or exact BR number. Returns BR number, English/Chinese name, type, incorporation/registration date, any name-change date, and the matching HKEX ticker when the name resolves to a listed stock.
• hk_company({ brn, since? }) — look up one company’s full history (initial incorporation/registration + any renames) by BR number.
• hk_new_companies({ since?, type?, limit? }) — companies newly incorporated or registered since a date, most recent first.
• hk_company_name_changes({ since?, limit? }) — companies that changed their registered name since a date, most recent first.

Auth

Keyless. data.gov.hk and cr.gov.hk are public, unauthenticated open data.

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 <a href>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:

• https://www.cr.gov.hk/docs/wrpt/RNC063/RNC063L_YYYYMMDD.csv — Hong Kong local companies (newly incorporated / re-domiciled / renamed)
• https://www.cr.gov.hk/docs/wrpt/RNC063/RNC063F_YYYYMMDD.csv — non-Hong Kong companies (newly registered / re-domiciled / renamed)

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 package_show 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. hk_company_search and hk_company default to a 12-week lookback unless since is given (as far back as 2024-12-30, the dataset start); hk_new_companies and hk_company_name_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 name_zh, everything else to name_en) rather than surfacing them as two different companies.

Scope limit — found during research, not assumed

This is the only company-level open dataset the Companies Registry publishes. Its other three data.gov.hk packages under org hk-cr (crdata-stat-non-hk-companies, crdata-stat-local-companies-incorporated, crdata-stat-local-companies) are aggregate monthly counts (public / private / guarantee company totals), not per-company records — checked live, they carry no name, BR number, or address fields. data.gov.hk’s org for the Inland Revenue Department (hk-ird) publishes zero datasets, so Business Registration data has no open API either.

There is no open, keyless API that returns a company’s registered address or status for an arbitrary Hong Kong company. That is the Companies Registry’s paid Cyber Search Centre (ICRIS) product — a per-document commercial search, not open data. So:

• This pack can resolve a name or BR number for anything newly incorporated, registered, or renamed since 2024-12-30.
• It cannot answer “what is the registered address of <any company>” for a company outside that window (most established companies, including every HKEX-listed blue chip) — there is genuinely no open source for that. Every tool description says so rather than let a caller assume more than the data supports.
• Money-lender and TCSP-licensee registers were in scope per the original ask; neither exists as an open dataset on data.gov.hk (checked: zero results searching “money lender”, “TCSP”, “trust company”, “licensed money lenders” against the CKAN API) — not built.

HKEX ticker join

hk_company_search and hk_company call the same keyless Yahoo Finance search endpoint @pipeworx/hk-stocks’s hk_resolve_symbol uses (called directly here, not cross-pack, since packs don’t call each other at runtime), restricted to .HK-suffixed symbols, and only attach a ticker on a normalized exact-name match (stripping “Limited”/“Ltd”/“Co”/“Holdings”/ “Group” and non-alphanumerics) — never a fuzzy guess. In practice this fires rarely: a company appearing in this feed was newly incorporated, registered, or renamed in the last ~20 months, and HKEX-listed companies are almost always older than that.

Data lag

The feed publishes roughly a week behind. A since date newer than the latest published week returns count: 0 with a data_lag_note field explaining that this is publication lag, not “no new companies” — check that field before reading a zero as a clean result.
