How verification works.

Three steps to confirm customer tax status before you bill or ship.

01
Enter the business details
Enter a European VAT number, national registry code, or company legal name through the web interface, bulk CSV upload, or REST API.
02
Verify against official registers
We query the European Commission VIES system and national commercial registers in real time to verify active trading status and registered address.
03
Keep the audit proof
Save official VIES consultation numbers under Regulation 904/2010 and company registry snapshots to defend zero-rated tax treatment during audits.

Ready to run your first check?Start free

Built for tax audits, not boolean guesses.

Tax authorities require proof that your customer was an active business on the date of supply. Here is how we prove it.

Official consultation proof: Every VIES check records the official consultation number required by Council Regulation 904/2010 Article 31 to prove due diligence.
Outages separated from invalid numbers: When government tax servers undergo maintenance, we report system unavailable instead of falsely charging your business buyers domestic VAT.
Dual tax and registry checks: We verify that the VAT number is active and that it legally belongs to the purchasing company in official registers.
Safe automated retries: Send requests with idempotency keys so your billing system can retry safely without double-billing or creating duplicate records.
Contemporaneous timestamps: Every verification records the exact second of observation to satisfy tax auditors during multi-year audits.

Monthly purchases are available only to explicitly approved organizations when billing is configured. Annual purchases and top-up purchases are unavailable. Bulk row and active-job limits are enforced per effective plan, with separate sandbox and live capacity. Saved import mappings are planned and unavailable in this release. The listed mapping counts are catalogue capacities for that future workflow. Prices in EUR, excluding applicable VAT. Four independent meters reset each UTC calendar month with no rollover. Bulk rows consume their operation-specific meters. No automatic overages. The accepted HTTP request rate ceiling does not promise source throughput. Live operation and jurisdiction readiness and private-beta approval remain separate conditions. Source and customer retention policy may shorten evidence history. Support response targets are not an uptime SLA.

Signed outbound webhooks are planned for a later release and cannot be configured in this release. Scheduled monitoring is planned for a later release and cannot be configured in this release.
