EU VAT number validation (VIES) with predictable behavior for agents.

EU VAT number validation (VIES) with predictable behavior for agents. Validates any EU VAT number against the European Commission's VIES service. Two modes: fast validation (may serve a cached result, labeled with its timestamp) and consultation-proof mode (always live, returns the official consultation number, requires requester identification). 'Not confirmed' does not imply the company is invalid. Machine-readable errors with per-member-state availability status.
