FAQ
- Are these identifiers safe to use in production?
- They are intended for non-production scenarios. Never submit generated values to government portals or tax authorities.
- Can I add another country?
- Not directly in the UI. Fork the generator or open a feature request with the format and checksum rules you need.
- Do the generators ensure uniqueness?
- Values are random each time but not tracked globally, so collisions are unlikely but possible. Regenerate if you need a fresh set.
