Data Sources
California data is read live from the California Secretary of State bizfileOnline portal (bizfileonline.sos.ca.gov). The register covers domestic and foreign corporations (stock, non-profit, professional, statutory close, cooperative), limited liability companies, limited partnerships, limited liability partnerships, and registered general partnerships.
The free public portal exposes: legal name, entity number, entity type, status, formation date, jurisdiction, registered agent (name, type, and address), principal office address, and mailing address.
Officer and manager rosters. v1 returns the registered agent only. Corporate officers, LLC managers, and member rosters require parsing the paid Statement of Information document and are not yet extracted. See the Data Availability table for the roadmap item.
LLC manager visibility. California required LLC Statements of Information to be filed through bizfileOnline starting 2022. LLC entities that have not refiled since then carry only their formation cover sheet with no manager or member data. Corporations are not affected.
Fast / onboarding mode. v1 serves all requests from the live portal (verification mode). A fast non-authoritative path backed by the Secretary of State bulk extract is on the roadmap for a future release.

Search Capabilities
Entity number search. bizfileOnline’s search index is name-based only. Searching by entity number works by expanding the number into name-stem variants and filtering results for an exact entity-number match. This means lookup by entity number is slower than lookup by name and may return no result if the entity’s legal name cannot be reconstructed from the number alone. Prefer name-based queries where possible.
Best-match picker. When multiple entities share the same legal name (for example an older merged-out entity and the current active one), the API prefers the entity with an exact name match and an Active status. If no Active match exists, it falls back to any exact name match, then to the first result.

Legal Forms
Legal form is read from theEntity Type field on the bizfileOnline detail page. bizfile renders the label in <Type> - <Jurisdiction> - <Sub> form (for example Stock Corporation - CA - General). The full label is preserved in legalForm.localName; standardization matches on the leading category.
California entity types and standardized forms
California entity types and standardized forms
bizfile occasionally surfaces niche entity types (Land Trust, Massachusetts Trust). These fall through with
standardized: Other and the full local label preserved. For the complete and current list of legal forms, see the pricing page.
