Luxembourg (LU)

Overview

Registry

RCS (Registre de Commerce et des Societes)Official company registry of Luxembourg

The RCS (Registre de Commerce et des Societes) is the official business register of Luxembourg, accessed via the LBR (Luxembourg Business Registers) XML API. Unlike many jurisdictions that rely on PDF document parsing, Luxembourg provides fully fielded structured XML data directly from LBR, with detailed shareholding information, court ruling data, and granular status codes. Lite Profile and Search are returned synchronously. Enhanced Profile fulfilment is covered under Enhanced Profile: async workflow below.

Field	Description	Example
`code`	NACE Rev. 2 code	`96.021`
`description`	Activity description	Coiffure
`type`	Classification type	NACE

Only approximately 28% of Luxembourg entities have NACE codes in the registry data. The company’s stated purpose (objet social) is available in activityDeclarations.

Address Format

Luxembourg addresses use a component-based structure: Example format:

10 rue du Test, 1234 Luxembourg

Address Components

PostalCode	postcode	4-digit postal code
Locality	city	City/town name
Country	country	Country name
CountryCode	isoCode	Converted from 3-letter to 2-letter ISO

Source data uses 3-letter ISO country codes (e.g., LUX, FRA, BEL) which are converted to 2-letter codes (LU, FR, BE) in the API response.

Implementation Notes

Fully Structured Data: Unlike jurisdictions that rely on PDF parsing (with 1-6 hour processing delays), Luxembourg provides fully fielded XML data directly from LBR, with structured shareholding information, detailed court ruling data, and comprehensive status tracking.

Capital and Shareholding Data

Structured Shareholding: Luxembourg provides fully fielded shareholding data including shareholder names, share counts, and share types - a significant advantage over jurisdictions where this data must be parsed from documents.

Share classes commonly include:

Parts de categorie A / Parts de categorie B - Class A/B shares
Parts sociales - Social shares
Actions - Regular shares

Capital type is indicated as either “Fixed” (Fixe) or “Variable”.

Foreign Entities

Field	Value
`registrationType`	”Foreign Registered Body”
`registrationTypeDetails`	Source jurisdiction information
`otherIdentifiers[].type`	”LU_FOREIGN_REG_CD”
`otherIdentifiers[].isoCode`	Source country code
`otherIdentifiers[].value`	Foreign registration number

Enhanced Profile: async workflow

Luxembourg Enhanced Profile is fulfilled synchronously on GET when the registry responds in time. A slower order is handled by the async order pattern: the request returns 202 with an orderId instead, and the profile is retrieved by polling GET /v2/orders/{orderId}. On V2, Enhanced Profile can also be ordered asynchronously from the start with POST /v2/companies/{kyckrId}/enhanced, polled the same way, with no held connection. See the async order pattern release notes for V2 and V1 for integration guidance. Lite Profile and Search remain synchronous and return data immediately.
