VAT Validation APIs
VAT validation APIs confirm that a business's VAT number is registered. vatcheckapi and vatlayer return the registered company details for EU numbers, EuroValidate also checks IBAN and EORI numbers via VIES, and TaxID and Tax Data reach beyond the EU to other national tax IDs. All of them are freemium and need an API key.
