Direct answer
Name rules are jurisdiction-specific; the official registry should be used to verify availability, restricted terms and the final registrability route.
Which authority applies
Each jurisdiction has its own registry, licensing and tax authorities. Identify the authority that controls your exact entity, activity and location, and use its current guidance as the controlling source.
Practical checklist
- Check existing and reserved names.
- Review restricted words and protected names.
- Check trademark conflicts separately.
- Keep the search evidence.
