FAQ
- Which countries are supported?
- Local format checks for NL (KvK/BTW), BE (KBO), DE (USt-IdNr.), FR (SIREN/SIRET/TVA), ES (NIF/CIF) and PT (NIF). VIES works for VAT ids across the EU.
- Is this an official company register lookup?
- No. Format and checksum run in your browser. Optional VIES confirms VAT status at the EU Commission, not full company profiles.
- Can I check a German Handelsregister number?
- This tool focuses on USt-IdNr. (DE + 9 digits) via format + VIES. Handelsregister file numbers vary by court and are not validated here.
