Validation workflow
- Entry of a VAT number and selection of the issuing country
- VIES SOAP request and interpretation of the validation response
- Additional GEMI lookup for Greek entities when information is available
Application

Design considerations
Reliable handling of external services and clear error messages are essential to the usability of business-facing validation tools.
