# Luxembourg (LU)
> Country guide for Luxembourg company data including registry information, identifiers, legal forms, and data availability.
## Overview
**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 orders complete synchronously when fulfilment is fast; slow orders currently time out, addressed by the upcoming async order pattern (preview) — see [Enhanced Profile — async workflow](#enhanced-profile--async-workflow) below.

## Status Codes

| (none) | Active entity | Active |
| en liquidation volontaire | Voluntary liquidation | Distressed |
| en liquidation judiciaire | Judicial liquidation | Distressed |
| en faillite | In bankruptcy | Distressed |

Luxembourg has 20 detailed observation codes for non-active statuses. The `statusDetailsBeta` field provides granular status information including court ruling dates, court names, and specific closure reasons.
## Activity Codes
Luxembourg uses **NACE Rev. 2** for classifying business activities.
| 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:**
```text theme={null}
10 rue du Test, 1234 Luxembourg
```
### Address Components
| Component | Maps To | Description |
| -------------- | ------------------------- | --------------------------------------- |
| BuildingNumber | streetNumber | Street number |
| BuildingName | buildingName | Building name (if applicable) |
| StreetName | streetName | Street name |
| Floor | (included in fullAddress) | Floor information |
| 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.
### Representatives
Luxembourg classifies representatives into multiple categories:
| Role | French | Description |
| ------------------------ | -------------------------------- | ------------------------------ |
| Director/Manager | Administrateur/Gerant | Directors and managers |
| Board Member | Membre | Board members |
| Daily Management | Delegue a la gestion journaliere | Daily management delegates |
| Permanent Representative | Representant permanent | Branch representatives |
| Partner | Associe | Partners (in partnerships) |
| Legal Agent | Agent legal | Liquidators, bankruptcy agents |
| Management Company | Societe de gestion | Fund management company |
### 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
For foreign-registered entities with a Luxembourg presence:
| 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 |
### Branches/Establishments
Branch data is available in `beta_establishments[]` (beta feature) and includes:
* Branch address and trading name
* Permanent representatives specific to the branch
* Branch creation date and active status
**Beta Feature**: The `beta_establishments` array contains branch/establishment data and may be subject to changes. Contact support for details on accessing this data.
## Enhanced Profile — async workflow
**Luxembourg Enhanced Profile uses a mixed sync / async fulfilment pattern.** Some orders complete within the \~40s connection-hold window; others exceed it. For slow orders the endpoint returns `202` with an `orderId` instead of timing out — retrieve the completed profile via the polling workflow.
Once the async order pattern is live, build for both responses on V1: handle the `200` (fast path) and the `202` (async path). For V2 production integrations — use `POST /v2/companies/{kyckrId}/enhanced` + poll `GET /v2/orders/{orderId}`, which returns an `orderId` immediately with no server-side connection hold.
See the V1 ([GET + 202 fallback](/company-v1/developer-news/2026-06-async-order-pattern)) and V2 ([POST + poll recommended](/company-v2/developer-news/2026-06-async-order-pattern)) release notes for full integration guidance.
Lite Profile and Search remain synchronous and return data immediately.
