Quick check
| Check | Why it matters | Where to verify |
|---|---|---|
| Official registry search | Name availability is decided by the filing jurisdiction. | Secretary of State or company registry |
| Entity type | LLC, corporation, nonprofit, and trade name rules can differ. | Formation guidance |
| Reserved or similar names | A name can be blocked even if no exact match appears. | Registry name rules |
| Trademark conflict | Registry availability does not clear trademark risk. | Trademark office search |
| Local license name | City, tax, or permit records may use a separate DBA or trade name. | Local agency |
Step-by-step verification
- Choose the jurisdiction where you plan to form or register the business.
- Search the official business registry for exact and similar names.
- Read the jurisdiction's name availability and restricted-word rules.
- Check whether a name reservation is required or optional.
- Run separate checks for trademarks, domain names, local licenses, and tax permits.
What can differ

FAQ
Does a domain name mean the business name is available?
No. Domain availability, business registry availability, and trademark risk are separate checks.
Should I check similar names?
Yes. Some registries reject names that are too similar to existing entities.
Is name availability legal advice?
No. Use official registry rules and get qualified advice for trademark or legal conflicts.
