European Company Search: Multi-Country Register Lookup

Search one company name across the official French, Norwegian and Czech company registers in a single run, and get every match back in one common shape. Built for cross-border due diligence, KYC onboarding and supplier screening, where the first problem is always the same: the company exists, but you do not know which register holds it.

No scraping, no API keys. Every register used here is a documented public API licensed for commercial reuse.

Annuaire des Entreprises (DINUM)	France	SIREN	Licence Ouverte 2.0

id, idType	SIREN, ORGNR or ICO — the local identifier, so you can join to the national register
name	Registered name
legalFormCode, legalFormName	Local legal form code
status	Normalised where possible: active, dissolved, bankrupt, under liquidation
establishedDate, dissolvedDate	ISO-8601
address, postalCode, city, country	Registered address
industryCode, industryName	Local activity code (NAF, NACE, CZ-NACE)
employees	Where the register reports it
vatId	Where available
extra	Register-specific extras: directors and accounts for France, website and previous names for Norway, per-register status for Czechia

Sample output

A real run for Equinor, trimmed:

[
  {
    "countryCode": "FR", "countryName": "France",
    "id": "450324215", "idType": "SIREN",
    "name": "EQUINOX (EQUINOX - LES SAVEURS OCEANES)",
    "legalFormCode": "5499", "status": "A",
    "city": "SAINT-PIERRE-D'OLERON"
  },
  {
    "countryCode": "NO", "countryName": "Norway",
    "id": "923609016", "idType": "ORGNR",
    "name": "EQUINOR ASA",
    "legalFormCode": "ASA", "legalFormName": "Allmennaksjeselskap",
    "status": "active", "city": "STAVANGER",
    "extra": { "website": "http://www.equinor.com", "vatRegistered": true }
  }
]

Notice the value of the aggregation: the French name search returns a similarly-spelled company, the Norwegian one returns the entity you meant. Seeing both side by side is the point.

Usage

Find a supplier across the three registers

{ "name": "Asseco", "countries": ["FR", "NO", "CZ"], "maxPerCountry": 25 }

One country only

{ "name": "Equinor", "countries": ["NO"], "maxPerCountry": 10 }

Pre-screen before onboarding

{ "name": "Novak", "countries": ["CZ"], "maxPerCountry": 100 }

Check status on the results: a dissolved or bankrupt entity is a different conversation.

Notes and limits

• Name matching is per-register and literal. Each register runs its own search algorithm; there is no fuzzy cross-register entity resolution here. Use this to find the entity and its local ID, then use the country-specific Actor for the full record.
• Different registers know different things. France publishes directors and filed accounts; Norway publishes website, previous names and bankruptcy state; Czechia publishes per-register status. Missing fields mean the register does not hold them, not that they are absent.
• Czechia caps a query at 1,000 results and returns a 400 beyond that; the Actor treats it as "no results" rather than failing the run.
• Register coverage is deliberately small. Only registers with an explicit commercial licence and a keyless API are included. Adding a country means verifying its licence first.
• Attribution is required by each licence and is included on every row.
