VAT validation and company data lookup by country
For tax number validation and filling in company details, Demona uses the most reliable register available per country: NAV in Hungary, the national register in several countries, and the EU VIES system in the other member states. Countries not listed have no automatic lookup.
| Country | Tax number validation | Company details |
|---|---|---|
| Hungary | NAV | NAV |
| Romania | ANAF, falling back to VIES | ANAF, falling back to VIES |
| Czech Republic | ARES, falling back to VIES | ARES, falling back to VIES |
| Poland | Biała Lista, falling back to VIES | Biała Lista, falling back to VIES |
| France | VIES | Recherche Entreprises, falling back to VIES |
| Finland | VIES | PRH, falling back to VIES |
| Denmark | no validation | CVR business register |
| Norway | Brreg (not an EU member) | Brreg |
| United Kingdom | HMRC | HMRC |
| Other EU member states | VIES | VIES |
"Falling back to VIES" means that if the national register finds nothing or does not answer, the system searches VIES.
Hungarian partners: the NAV lookup needs the team's own NAV credentials and the Validate Hungarian tax numbers via NAV option; filling in company details also needs Auto-fill company data from NAV. If validation is off, the lookup says so, and the weekly automatic partner check uses VIES instead.
The other sources are public registers; the team does not need to set anything up for them.
