EU Company Data Scraper: KVK, Impressum & VAT (VIES)

Turn a list of company websites into verified company facts. For every website this Actor reads the homepage and the pages that matter (Impressum / legal notice, contact, about, terms) and returns:

• Registration numbers: Netherlands KVK, Belgium KBO/BCE (checksum-validated), Germany Handelsregister (HRB/HRA + court), Austria Firmenbuch (FN), Switzerland UID (checksum-validated), France SIREN/SIRET (checksum-validated)
• EU VAT numbers for all 27 member states, checked live in VIES (European Commission), with the official registered name and address where the member state provides them. Belgian and French VAT numbers are also worked out from the enterprise number or SIREN on the site, and kept only when VIES confirms them
• Summary columns with one value each (registration number, VAT number, VIES name, e-mail, phone, address), ready for a spreadsheet: see the Summary view
• Address (schema.org), Dutch postcodes
• Company e-mail addresses (role mailboxes such as info@, sales@, kundenservice@) and landline phone numbers
• Social profiles of the company (LinkedIn company page, Facebook, Instagram, X, YouTube, TikTok, Xing)
• Company name, the site's own rating (schema.org), and for every fact the page it came from and the exact text

You only pay for websites where at least one company fact was found.

Typical uses

• Enrich Google Maps results: run the Google Maps Scraper, then pass its dataset ID here. Each place gets its registration and VAT number; sourceItems keeps the title and placeId of every place with that website (chains are checked and charged once), so you can join the two.
• Run it automatically after the Google Maps Scraper: on the Google Maps Scraper's Integrations tab, add this Actor. Each finished Google Maps run then starts this Actor with its results.
• Supplier and customer checks (KYB light): confirm that a website belongs to a registered company with a valid VAT number.
• CRM clean-up: add registration numbers and official names to a list of company domains.
• E-invoicing and VAT compliance: find and validate the VAT numbers of business customers.

Input

Field	Description
urls	Websites or domains (example.nl, https://www.example.de/kontakt). Each website is checked once.
datasetId	Optional: the dataset of another run, for example the Google Maps Scraper.
datasetUrlField	Field in that dataset that holds the website (default website).
maxPagesPerSite	Homepage plus the most relevant pages, 1–10 (default 5).
verifyVat	Check VAT numbers in VIES (default on).
maxConcurrency	Websites in parallel (default 10). Each site itself is crawled at one request per second.

status is one of: ok (facts found, charged), no_data (nothing found, not charged), robots_disallowed, tdm_reserved, unreachable, invalid_input, skipped_timeout or skipped_charge_limit (all not charged).

• The summary columns repeat the most reliable entry of each list: the first registration number, the first VAT number that VIES confirmed (otherwise the first found), the official name from VIES, the first company e-mail address on the company's own domain. The lists keep everything that was found.
• derivedFrom marks numbers that were worked out instead of read: a Belgian enterprise number from a Belgian VAT number ("VAT"), or a VAT number from a Belgian enterprise number or French SIREN ("BE_KBO", "FR_SIREN"). Worked-out VAT numbers are only returned when VIES confirms them.
• serviceProviders: numbers of the hosting provider that the legal notice names ("Hébergeur : OVH SAS, RCS Lille ..."). They are kept apart so they are not mistaken for the company's own numbers.

Large lists: with the default settings the Actor checks about 2 websites per second (roughly 7,000 per hour). If the run timeout is about to be reached, it stops starting new websites, returns the rest as skipped_timeout (free) and still finishes successfully, so you can run those again or increase the timeout in the run options. The same applies to your maximum cost per run: websites that no longer fit are returned as skipped_charge_limit, and VAT checks are only made for websites that are delivered.

Pricing

Pay per event:

• Company facts found: per website with at least one fact (status: ok)
• VAT check: per VAT number with a definitive answer from VIES. A VAT number worked out from a registration number is only charged when VIES confirms it (at most 2 per website).

Websites without results, blocked or unreachable websites and invalid input are free.

Responsible by design

• No personal data as a product. Personal names are never extracted. E-mail addresses are only returned when they are role mailboxes (info@, sales-de@, hemaklantenservice@...); addresses that may name a person (jan.jansen@) are dropped and only counted. Mobile numbers are dropped, because for sole traders they are personal.
• robots.txt is respected for every page, and the crawler identifies itself as EUCompanyFactsBot.
• Text and data mining opt-outs are respected (TDMRep tdm-reservation, EU DSM Directive art. 4): such sites are skipped.
• No bypassing: no proxies, no headless browser, no CAPTCHA solving. Sites that block bots are reported as unreachable.
• VAT data comes from VIES, the official public service of the European Commission.

You remain responsible for how you use the data, including the GDPR and national rules on unsolicited e-mail.

What to expect

Measured in November 2026 (version 0.2) on 240 small-business websites taken from OpenStreetMap (shops, crafts and offices, 40 per country). Share of all websites in the sample:

Country	Charged (facts found)	Registration number	VAT number	Valid in VIES	Company e-mail	Phone
Germany	82%	50%	68%	68%	68%	60%
Netherlands	75%	35%	20%	20%	48%	40%
Belgium	75%	52%	50%	45%	52%	40%
Austria	68%	40%	48%	48%	42%	30%
Switzerland	62%	28%	– (not in VIES)	–	50%	35%
France	57%	42%	32%	22%	40%	20%

About 11% of websites block bots and 6% disallow crawling in robots.txt; those are reported and free. Sole traders, doctors and many small shops have no commercial register number at all, so 100% is not possible. VIES France was busy during the measurement: 5 French VAT numbers got no answer (vies.error MS_MAX_CONCURRENT_REQ); such checks are free and can be run again later.

Limitations

• How often a registration number is shown differs per country. It is a legal requirement on German and Austrian sites (Impressum) and Belgian sites (enterprise number), so the hit rate there is high. On Dutch sites the KVK number is often missing.
• Sites that render their content only with JavaScript, or that block bots, give fewer or no results.
• Germany and some other member states do not share the registered name and address through VIES; the check then only says whether the number is valid.
• The site's own rating (selfReportedRatings) is what the company publishes about itself, not an independent score.
