Data Sources

Luxembourg uses a single official register, the RCS, as its data source. What you get depends on the mode:

Onboarding mode (company only): read live from the register’s public data. Returns the RCS number, company name, legal form, registration date, NACE code and registered seat. Status is derived from enforcement measures published by the register.
Verification mode (company, legalRepresentatives, shareholders): extracted with AI parsing from the certified trade register extract (“Extrait du RCS”). All three datapoints come from the same extract and are billed as one block (see pricing).

All company types

RCS (Registre de Commerce et des Societes) — Operated by Luxembourg Business Registers (LBR), an economic interest grouping comprising the State, the Chamber of Commerce, and the Chamber of Skilled Trades, under the authority of the Ministry of Justice since 2003. The RCS is the central commercial register for the Grand Duchy of Luxembourg, containing registration data for virtually all legal entities: commercial companies, partnerships, sole traders, civil companies, non-profit associations (ASBLs), foundations, investment funds, and branches of foreign entities. In verification mode, company name, legal form, status, registration date, registered address, share capital, activities, legal representatives, and shareholders are AI-parsed from the certified extract.
VIES (VAT Information Exchange System) — The EU-wide VAT validation service is used during VAT number searches to resolve a Luxembourg VAT number to a company name, which is then used to search the RCS. In verification mode, VIES also validates the VAT number found on the extract, and the result is returned as taxId with its verification status.

Document-based data extraction: Officers and shareholders are only published on the certified extract (“Extrait du RCS”), so verification mode extracts them from that document using AI parsing. Data quality depends on the document content and parsing accuracy. Onboarding mode does not use the extract and returns only the base fields the register publishes.

Company Identifiers

Query Identifiers

Company Type	Source	Format	Example	Notes
Commercial companies	RCS	Letter prefix + digits	`B246607`	Standard RCS registration number
By VAT number	VIES	LU + 8 digits	`LU32326416`	EU VAT number lookup via VIES

RCS Number Format: The Luxembourg RCS number consists of a letter prefix followed by digits (e.g., B246607). The prefix indicates the entity type: B for commercial companies is the most common. The regex validation pattern is ^[A-Z]\d+$.

RCS Number Prefixes

Prefix	Entity Type
`A`	Sole traders (commercants personnes physiques)
`B`	Commercial companies (SA, SARL, SAS, SCA, etc.)
`C`	Groupements d’interet economique (GIE)
`D`	Groupements europeens d’interet economique (GEIE)
`E`	Civil companies (societes civiles)
`F`	Non-profit associations (ASBL)
`G`	Foundations (fondations)
`H`	Agricultural associations
`I`	Pension savings associations
`J`	Public establishments

Identifiers in API Response

Once you retrieve company data, the identifiers object contains all available identifiers for that entity:

Identifier Type	Format	Example	Found In
`rcs`	Letter prefix + digits	`B246607`	All registered entities
`VAT`	8 digits (no `LU` prefix)	`32326416`	Verification mode, companies with a VAT number on the extract
`euid`	Register-issued European identifier	`LURCSL.B781`	When available

Search Capabilities

Search Type	Pattern	Example	Match Type	Expected Results
By RCS Number	Letter + digits	`B246607`	Exact	Exact match returned first (matchType: id); other results may follow
By VAT Number	LU + 8 digits	`LU32326416`	Exact via VIES	Exact match returned first (matchType: id); other results may follow
By VAT (no prefix)	8 digits	`32326416`	Exact via VIES	Exact match returned first (matchType: id); other results may follow
By Name	Text string (min 3 chars)	`"VREF Germany"`	Fuzzy	Multiple results

Search Performance: Identifier-based searches (RCS number, VAT) provide exact matching and faster results. Name searches query the RCS directly and may return multiple results across the register.

VAT Search Flow: VAT searches follow a two-step process: (1) validate the number via VIES to retrieve the official company name, then (2) search the RCS by that company name. The matched company is flagged as an id match and promoted to the top of results. Both formats are accepted: with country prefix (LU32326416) and without (32326416).

Search reliability: All search operations include built-in retry handling for reliability against the RCS API.

Quirks & Gotchas

Quirk	Details
Verification data is AI-parsed from the extract	In verification mode, company data, legal representatives, and shareholders are extracted from the certified trade register extract (PDF) via AI parsing. Onboarding mode returns only the base fields the register publishes.
Asynchronous document delivery	The certified extract is delivered asynchronously, usually within about an hour.
Asynchronous company data in verification mode	Because verification-mode `company` depends on the certified extract, it stays `processing` until the document is received and parsed. Onboarding-mode `company` does not wait for the extract.
Status detection is heuristic + AI	In verification mode, status is first detected by keyword search in the document text for closure terms (“radiee”, “dissous”, “dissolution”), then AI-enriched for standardization. Edge cases may exist for unusual status descriptions. In onboarding mode, a company under a published enforcement measure is returned as inactive.
One NACE code per company	The register publishes a single NACE code per company. Returned NACE and ISIC codes are standardized with AI: from the extract in verification mode, and from the register’s NACE label in onboarding mode.
RCS number prefix indicates entity type	The letter prefix is the RCS section (e.g., `A` for sole traders, `B` for commercial companies, `F` for ASBLs, `G` for foundations). See the prefix table above.
VAT format is 8 digits	Luxembourg VAT numbers are `LU` + 8 digits (e.g., `LU32326416`), shorter than most EU countries. The API returns them without the `LU` prefix (`32326416`). Search accepts both forms.
Several document types	Besides the certified Extrait du RCS, RESA publications and RCS filings (including annual accounts) are listed in `availableDocuments`. UBO certificates are not available.
No UBO data	Luxembourg maintains a Register of Beneficial Owners (RBE), also managed by LBR, but this register is not currently integrated. UBO data is not available from the RCS extract.
Document is also the data source	The Extrait du RCS serves a dual purpose: it is both the official company document delivered to the user and the source from which verification-mode data is AI-parsed. Company, legal representatives, and shareholders from the extract are billed as one block.
SCSp has no legal personality	The Societe en commandite speciale (SCSp) is a legal form without legal personality, used primarily as an investment vehicle. It is registered in the RCS but may have limited data in the extract.

Mappings

Company Status

Company status is determined from the trade register extract document using a two-step process: (1) a keyword-based heuristic checks for closure indicators in the document text, then (2) the status is AI-enriched for standardization.

Local Status	English Translation	Standardized Status	Detection Method
Active	Active	`ACTIVE`	No closure indicators in document
Radiee	Struck Off	`CLOSED`	Document contains “radiee”
Dissous	Dissolved	`CLOSED`	Document contains “dissous”
Dissolution	Dissolution	`CLOSED`	Document contains “dissolution”
En liquidation	In Liquidation	`UNDER_INSOLVENCY_PROCEEDING`	AI-inferred from document context

If no closure indicators are found in the document text, the company is considered Active by default. The AI enrichment step maps the detected status to a standardized CompanyStatus enum value (ACTIVE, CLOSED, UNDER_INSOLVENCY_PROCEEDING, or UNKNOWN).

Legal Forms

Luxembourg legal forms are extracted from the RCS trade register extract via AI parsing. The legalFormCode field from search results provides an initial abbreviation, while the full legal form name is parsed from the certified extract document and AI-enriched to add English translations, standardized types, and ISO 20275 codes.

Because legal form standardization and ISO 20275 assignment are AI-enriched, exact mappings may evolve. The local Luxembourg legal form name from the RCS document is always preserved verbatim.

Legal Representatives

Legal representatives are extracted from the RCS trade register extract via AI parsing. The AI looks for specific role terms in the document text, such as “Gerant”, “Administrateur”, “Directeur”, “President”, and “Membre du conseil d’administration”. Roles are then AI-enriched with standardized English translations and ISO 5009 codes (when an ISO 20275 ELF code is available for the company’s legal form).

Executive & Management Roles (Legal Representatives)

French Role	English Translation	Standardized	Typical Entity Type
Gerant	Manager	Manager	SARL, SCS
Gerant unique	Sole Manager	Manager	SARL (single manager)
Administrateur	Director	Director	SA
Administrateur-delegue	Managing Director	Managing Director	SA
Directeur	Director	Director	Various
Directeur general	Chief Executive Officer	Chief Executive Officer	SA
President	President	President	SAS
President du conseil d’administration	Chairman of the Board	Chairman of the Board	SA
Vice-president	Vice President	Vice President	SA, SAS
Associe-gerant	Managing Partner	Managing Partner	SCS, SCSp
Associe commandite	General Partner	General Partner	SCA, SCS
Liquidateur	Liquidator	Liquidator	Companies in liquidation

Supervisory & Control Roles (Other Key Persons)

French Role	English Translation	Standardized	Typical Entity Type
Commissaire aux comptes	Statutory Auditor	Auditor	SA, SARL (above threshold)
Reviseur d’entreprises	Certified Auditor	Auditor	Various
Reviseur d’entreprises agree	Approved Statutory Auditor	Auditor	SA (large companies)
Membre du conseil de surveillance	Supervisory Board Member	Supervisory Board Member	SA (dual board structure)
President du conseil de surveillance	Chairman of the Supervisory Board	Supervisor	SA (dual board structure)
Secretaire	Secretary	Secretary	Various

Both individuals and corporate entities can hold legal representative and other key person roles in Luxembourg companies. The classification of each role as legal representative (can legally bind the company) or other key person (supervisory, audit roles) is AI-enriched using ISO 5009 codes when the company’s ISO 20275 (ELF) code is available.

Shareholders

Shareholders are extracted from the RCS trade register extract via AI parsing. The AI looks for Luxembourg-specific shareholder terminology in the document text.

Extraction Logic

The AI parser identifies shareholders from specific sections of the trade register extract:

Source Section	Terms Searched	Data Extracted
Associe(s)	Associes, Actionnaires, Associe unique	Shareholder name, registration number, legal form, address
Parts sociales	Parts detenues, Nombre, Type(s) de parts	Share count, share type
Capital social	Apport, Participation au capital	Total capital for percentage calculation

Ownership Fields

Field	Description	Source
`sharePercentage`	Ownership percentage	Calculated from shares held / total shares
`type`	`individual` or `company`	Determined by AI from shareholder details
`numberOfShares`	Number of shares held	From “Parts detenues” section
`company.id`	RCS number of corporate shareholder	From “N d’immatriculation au RCS”
`company.legalName`	Name of corporate shareholder	From “Denomination” section
`company.countryCode`	Country of corporate shareholder	Inferred from registration details

Shareholder extraction quality depends on the structure and completeness of the trade register extract document. Both individual and corporate shareholders are supported. Percentage calculation is derived from the ratio of shares held to total shares when available. Not all legal forms publish shareholder information in the RCS extract — SAs (public limited companies) typically do not list individual shareholders in their extracts.

Activity Code Mapping

Luxembourg uses the NACE Rev. 2 classification. The register publishes one NACE code per company. Returned NACE and ISIC codes are standardized with AI: in verification mode from the activity found on the extract, and in onboarding mode from the register’s NACE label. The system maps activity codes across two levels:

NACE Rev. 2 (European) --> ISIC Rev. 4 (International)

Classification	Source	Example	AI Inferred?
NACE	Register NACE code or activity on the extract, standardized with AI	`7022`	Yes
ISIC	Derived from NACE via mapping tables or AI	`7020`	Yes

When company data is AI-parsed from the trade register extract, activity descriptions may also be extracted from “Objet social” or “Activite principale” sections and used for the activity classification.
