California Business Entity Search – Secretary of State

Perform a California business search to research entity information or determine the availability of a proposed company name. Before forming an entity, a search can help identify exact or similar name matches. A close match may mean the chosen name is unavailable.

Business Entity Search

1. Open the Business Search Page

2. Enter Search Information

Use the field at the bottom of the search page to enter an entity name or file number. A name search can check availability, while a file number search locates a specific business.

After entering the entity details, select either the magnifying glass to run the search or Advanced to access filters (see image).


3. Refine Search (Optional)

If Advanced was selected, a pop-up will appear with the following filter options:

  • Search Filter
  • Search Type
  • Entity Type
  • Status
  • Initial Filing Date

Use the advanced options to refine the search as needed. When ready, select Search to review the results.


4. Review Search Results

Matching entities will appear in a results list. Each result shows the full entity name on the left, along with a few other basic business details.

Selecting one of the entities listed in the blue column below Entity Information opens a window on the right containing additional details.

Name Availability Tip: A name search with no matching results generally indicates that the name is available for a new business registration.
