GUIDE & INSIGHTS
EU VAT Identification Syntax & Format Validation Rules
For tax-exempt intra-community B2B supplies or cross-border services within the European Union, verifying the recipient VAT identification number (VAT ID) is mandatory. Every EU member state adheres to a standardized country prefix followed by specific alphanumeric structure patterns (e.g., DE + 9 digits for Germany, AT + U + 8 digits for Austria, NL + 9 digits + B + 2 digits for Netherlands). Format and syntax validation checks ensure structural compliance prior to conducting qualified VIES engine queries.
