What is a DBA?
A DBA (Doing Business As) is a fictitious business name registration that allows individuals and businesses to operate under a name different from their legal name or registered entity name.
Why Search DBAs?
- Verify business name availability
- Research competitors
- Due diligence investigations
- Find business owner information
DBA vs Entity Registration
- DBAs: Filed at county level
- LLCs/Corporations: Filed with Secretary of State
- DBAs: No liability protection
- Entities: Limited liability protection
Important Distinction
California DBAs are filed with county clerks, not the Secretary of State. Each county maintains its own database, making comprehensive searches more complex.
