Hong Kong

Data Sources

Hong Kong uses a single official registry for company data. For a given entity, all data comes from one source — the Companies Registry’s online portal.

All company types

ICRIS (Integrated Companies Registry Information System) — Operated by the Hong Kong Companies Registry (a department of the Financial Services and the Treasury Bureau), ICRIS is the sole data source for all Hong Kong entities. The Companies Registry was established under the Companies Ordinance (Cap. 622), which came into effect on 3 March 2014, replacing the former Companies Ordinance (Cap. 32). ICRIS provides two access channels: (1) a structured Open Data API (data.cr.gov.hk) for company search by name or BRN, returning basic company particulars (name, type, address, incorporation date); (2) Company Particulars pages accessible via the e-Services Portal (e-services.cr.gov.hk), which provide comprehensive company information including directors, company secretary, share capital, and shareholder details.

Company profile data (legal representatives, shareholders, share capital, detailed company information) is AI-extracted from the ICRIS Company Particulars page, retrieved from the ICRIS e-Services Portal. Search results come from the structured ICRIS Open Data API.

Company Identifiers

Query Identifiers

Company Type	Source	Format	Example	Notes
All companies	ICRIS	8 digits (BRN)	`77054426`	Business Registration Number

BRN vs CI Number: Always use the Business Registration Number (BRN, 8 digits) when querying the API. The Certificate of Incorporation (CI) number is a separate identifier and will not work with our endpoints.

Identifiers in API Response

Identifier Type	Format	Example	Found In
`brn`	8 digits	`77054426`	All companies

Search Capabilities

Search Type	Pattern	Example	Match Type	Expected Results
By BRN	8 digits	`77054426`	Exact	Single company (1 result)
By Name	Text string	`"Technology Advantage"`	Prefix	Multiple results (begins-with match)

Search Performance: Use BRN-based searches for exact matching and best performance. Name searches use a begins_with match on the ICRIS Open Data API — partial names must match from the beginning of the company name.

Quirks & Gotchas

Quirk	Details
BRN vs CI Number	Always use the Business Registration Number (BRN, 8 digits), not the Certificate of Incorporation (CI) number. They are different identifiers.
Bilingual names	Hong Kong companies can have an English name, a Chinese name, or both. The ICRIS API returns both when available. The `legalName` field returns the English name if available, falling back to Chinese.
Prefix-match name search	Name searches use a `begins_with` match on the ICRIS Open Data API, not fuzzy search. Partial names must match from the beginning.
Company Secretary is mandatory	Every HK company must have a Company Secretary, which can be an individual or a corporate entity. This role appears under legal representatives.
No UBO data	Ultimate Beneficial Owner information is not publicly disclosed in Hong Kong. Companies must maintain a Significant Controllers Register (SCR) internally, but this is not accessible via the Companies Registry.
All profile data is AI-extracted	Company profile data (beyond basic search fields) is AI-extracted from the ICRIS Company Particulars HTML page. Data quality depends on parsing accuracy.
Share capital in HKD	Share capital is typically denominated in Hong Kong Dollars (HKD). Some companies may have share capital in other currencies.
All activity codes are AI-inferred	Hong Kong does not provide structured activity codes in ICRIS. NACE and ISIC codes are always AI-inferred from business descriptions when available.
Retrieval time ~3 minutes	The Company Particulars page is retrieved from the ICRIS e-Services Portal. Requests have a 5-minute timeout with automatic retries.
Address may be in Chinese only	Registered office addresses on the Company Particulars page are sometimes in Chinese only, without English transliteration.
Company profile charges a register extract	A company profile request includes retrieval of the Company Particulars document from the official registry. This means `companyProfile` incurs the cost of the register extract SKU.

Mappings

Company Status

Company status is AI-extracted from the ICRIS Company Particulars page. The AI parser identifies status indicators in the HTML content.

Local Status	English	Standardized Status	Notes
Live	Live	Active	Company is currently active
Dissolved	Dissolved	Closed	Company has been dissolved
Winding Up	Winding Up	Under Insolvency Proceeding	Company is in liquidation
Struck Off	Struck Off	Closed	Company removed from register by the Registrar

Status mapping is AI-inferred from the Company Particulars page content. The local status value is preserved verbatim as it appears on the ICRIS page.

Legal Forms

Hong Kong company types are identified from the ICRIS Company_Type field in search results and from the Company Particulars page. The mapping to standardized forms and ISO 20275 (ELF) codes is AI-enriched.

Legal form standardization and ISO 20275 assignment are AI-enriched. The local company type from ICRIS is always preserved verbatim.

Under the Companies Ordinance (Cap. 622), Section 66, the following types of companies may be formed in Hong Kong:

Private Companies

Local Name	Standardized	ISO 20275	Notes
Private company limited by shares	Limited Liability Company	254M	Most common company type in Hong Kong
Private unlimited company with share capital	Unlimited Company	-	Members have unlimited liability
Private unlimited company without share capital	Unlimited Company	-	Very rare

Public Companies

Local Name	Standardized	ISO 20275	Notes
Public company limited by shares	Corporation	-	Listed or unlisted public companies
Company limited by guarantee	Nonprofit Organization	-	Common for charities, clubs, and professional bodies; cannot have share capital under Cap. 622

Foreign Entities

Local Name	Standardized	ISO 20275	Notes
Registered non-Hong Kong company	Branch or Representative Office	-	Foreign companies registered under Part 16 of the Companies Ordinance

Legal Representatives

Legal representatives are AI-extracted from the ICRIS Company Particulars page. Names can be in English, Chinese, or both. Both individuals and corporate entities can hold the Director role.

Local Role	English Translation	Classification
Director	Director	Legal Representative

Other Key Persons

Local Role	English Translation	Classification
Company Secretary	Company Secretary	Other Key Person

In Hong Kong, a Company Secretary is a mandatory statutory position for all companies incorporated under the Companies Ordinance. The Company Secretary can be either an individual or a corporate entity. In our API response, the Company Secretary appears under legalRepresentatives with a standardized role of “Secretary”.

Shareholders

Shareholders are AI-extracted from the ICRIS Company Particulars page when shareholding information is disclosed.

Extraction Logic

Source	When Used	Data Extracted
Company Particulars (ICRIS)	Always (when available)	Shareholder names, share classes, number of shares held

Ownership Fields

Field	Description	Source
`name`	Shareholder name (individual or corporate)	AI-extracted from Company Particulars
`type`	Individual or Company	AI-inferred from name format
`sharePercentage`	Ownership percentage	Calculated from shares held vs total issued shares (when available)

Shareholder availability depends on the company type and what is disclosed on the Company Particulars page. Private companies limited by shares typically show share capital structure, but individual shareholdings may not always be detailed in the public record. Shareholders are not available for guarantee companies (which have members, not shareholders).

Activity Code Mapping

Hong Kong does not use a standardized national industry classification code in the ICRIS Company Particulars page. Activity information, when available, is extracted from the company’s stated objects or business description and mapped via AI:

Business Description (free text) → AI → NACE Rev. 2 + ISIC Rev. 4

Classification	Source	AI Inferred?
Business Description	Company Particulars (when stated)	No (official text)
NACE	AI-derived from business description	Yes
ISIC	AI-derived from business description	Yes

Hong Kong uses the HSIC (Hong Kong Standard Industrial Classification) for statistical purposes, but this code is not present in Company Particulars data. Both NACE and ISIC codes are therefore always AI-inferred when activity data is available.

Data Source Priority & Routing

Hong Kong uses a single-source model — all data comes exclusively from the ICRIS (Companies Registry). There is no priority chain or cross-registry merging.

Data Flow for Company Profile:

Search — The ICRIS Open Data API (data.cr.gov.hk) is queried for basic company lookup by BRN or name
Document Retrieval — The Company Particulars page is retrieved from the ICRIS e-Services Portal
AI Parsing — The page content is parsed by AI models to extract: company information, legal representatives, and shareholders
Result Assembly — The AI-extracted data is assembled into the standardized API response

Requests have a 5-minute timeout with automatic retries on the document retrieval step.
