How it works
Send a Tax ID. Get a verified answer.
Submit a Tax ID via API. We validate it against the relevant tax authority in real time and return the registration status, the company identity tied to that number, and a full verification trail — registry source, jurisdiction, and timestamp.
When a regulator asks where your data comes from, you have an answer.
Available via API for real-time validation, or as part of the bulk company dataset for batch processing.

Use cases
Where Tax ID validation matters.
Tax compliance at scale
Fintech and tax-tech platforms that process cross-border transactions need to validate tax ID registration in real time. Every invoice, every checkout, every onboarding flow. At volume, accuracy and speed aren’t optional.
Onboarding & KYB
Verify that a company’s Tax ID is active, matches the stated legal entity, and corresponds to the right jurisdiction — before you onboard them. A failed check costs less than a compliance incident.
Invoice validation
Accounts payable and procurement teams that need to confirm supplier tax ID status before processing invoices. Automated validation reduces manual checking and audit risk.
