🔹 Definition
VAT Validation refers to the process of verifying the legitimacy, structure, and registration status of a Value Added Tax (VAT) number assigned to a business entity within a VAT-implementing jurisdiction. This process helps ensure tax compliance in cross-border transactions, particularly within the European Union (EU), and supports Know Your Business (KYB) and anti-fraud measures in financial and commercial relationships.
VAT validation is essential for zero-rated intra-EU trade, eligibility for reverse charge mechanisms, and for detecting fraudulent or shell companies.

- Essential for automated onboarding and business verification in platforms and marketplaces
Q3: How is VAT validation performed?
- In the EU, through the VIES (VAT Information Exchange System) portal managed by the European Commission

Q4: What are red flags in VAT validation checks?
- VAT number is invalid or not recognized by the issuing country
