VAT Checker

The TrustComponent VAT Checker validates VAT and business identifiers against official registries — for a single ID, for large batches, or automatically on a recurring schedule. Every check is stored with the registry’s raw response as audit-ready evidence, and your systems can be notified of each result by webhook.

• Check a single VAT ID ad-hoc from the dashboard, or validate in batches via the API.
• Match company name and address against the registry record — field by field, using the registry’s own qualified-check verdicts where available (VIES, BZSt).
• Schedule recurring re-validation (monthly, quarterly, yearly) for ongoing compliance.
• Resolve edge cases by hand in the Manual Review Queue, or record verifications done outside the system.
• Keep evidence: the registry’s raw response is archived with every automatic check; attach screenshots or letters as additional evidence.
• Export audit-ready reports — tamper-evident PDF/JSON bundles per check or per ID, and bulk CSV/JSON/Excel exports.

• Tax Identifier — a stored VAT/business ID; the hub for all its checks, history, and schedules.
• Validation Request — a single check in progress (from the dashboard, the API, or a schedule). Once completed, only the result remains.
• Validation Result — the permanent outcome: Valid / Invalid / Unknown / Source unavailable / Not supported, the registry used, per-field match verdicts, the raw response, and any evidence.
• Schedule — recurring re-validation of one identifier on a monthly, quarterly, or yearly cadence.
• Manual Review — a queue for checks that need a human verdict.

The VAT Checker is a service inside a Project — add it under Create new or Settings → Services & Plans. Then:

1. Check your first VAT ID from VAT Checker → Overview → New validation — add the company name and address if you want them matched.
2. Review the result: outcome, registry, match verdicts, and the raw response.
3. (Optional) Attach a schedule for automatic re-checks, configure notification recipients in Settings, or integrate the API for batch and programmatic checks.
