Validate and generate tax IDs from Spain and Latin America offline. Batch mode, check digits and test data. 100% local. **The tax-ID validator that never sends your data to a website.** Accountants, HR teams, fintech ops and QA engineers validate NIFs, CUITs, RFCs and RUTs every day — by pasting them into ad-filled websites that see every number. ValidaFiscal does it instantly, inside your browser, offline. ✅ **Validate** with automatic type detection: paste the identifier and the extension works out which document and which country it belongs to ✅ **Batch mode**: paste a whole column, copy a CSV report (valid/invalid) ✅ **When invalid, it tells you why**: the expected control letter or check digit ✅ **Right-click** any selected number on a page → instant verdict ⚙️ **Test-data generator**: mathematically valid IDs for QA, sandboxes and seed data (they belong to no one) It covers the tax documents of Spain, Argentina, Mexico, Chile, Brazil, Peru and Colombia. **Private by design** • 100% offline: check-digit algorithms run on your device • No host permissions: the extension cannot read any web page • No account, no ads, unlimited validations, free
