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?
