OfficialProtect your business before every transaction
A quick EU or UK VAT lookup gives you authoritative, government-backed data — so you never sign, invoice, or pay based on guesswork.
Check before you transact
Looking up a company by VAT number — including a UK VAT check via HMRC — gives you authoritative, government-backed data before you sign a contract or send an invoice.
Fraud prevention
Confirm a company is legally registered before any payment or contract is signed. Fake VAT numbers are a common B2B fraud vector.
VAT compliance
EU and UK rules require you to verify a buyer's VAT status before applying zero-rate on cross-border B2B sales. One check keeps you audit-safe.
Company identity
Retrieve the registered company name and address straight from the tax authority — not from a self-declared form or a directory site.
Real-time status
VAT registrations can be revoked. A live check confirms whether the number is active right now, not just that it once existed.
API integration
Embed VAT validation directly into your checkout, onboarding, or ERP workflow with a single REST call. SDKs for Node, Python, and PHP.
Audit-ready records
Every lookup returns a timestamped verification record you can attach to invoices or tax filings as proof of due diligence.
