VAT Validator
Batch-check VAT formats and checksums locally, then optionally verify EU registrations with VIES
For Development & Testing Purposes Only - Synthetic Mock Data
About this tool
Batch-check VAT formats and checksums privately, then optionally verify EU registrations with VIES. VAT Validator runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- VAT Validator is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
