About this tool
Generate checksum-aware EU, UK and global VAT test numbers in JSON, CSV or SQL. Private, client-side and for QA only. VAT Number Generator 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 Number Generator 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.
