Data Sources

Oklahoma uses two tiers against the Oklahoma Secretary of State, Business Services Division. The register covers every domestic and foreign for-profit corporation, nonprofit corporation, limited liability company, limited partnership, limited liability partnership, and cooperative association formed in or qualified to do business in Oklahoma. No bulk-data extract is published for business entities; every request is resolved live against the portal.
  • Oklahoma Secretary of State public portal (free tier). The free Entity Summary page at sos.ok.gov/corp exposes the legal name, current status, legal form, jurisdiction, formation date, and the registered agent for any entity. This is what the free company-data block delivers. Officer and director rosters are not visible on this surface.
  • Oklahoma Secretary of State paid Entity Detail (paid tier). The Secretary of State charges a fee per entity to unlock the full Entity Detail view, which adds the officer/director/general-partner roster, the principal-office address, active commercial tradenames (DBAs), the duration, and the full filing history. Purchase the paid Entity Detail block to receive legalRepresentatives.
Two-block model. The free company + otherKeyPersons datapoints (registered agent) are delivered by the base company-data block. legalRepresentatives (officers, directors, general partners) require the separate paid Entity Detail block. See the pricing page for block pricing.

Company Identifiers

Query Identifiers

Oklahoma Filing Numbers are 10 numeric digits. Unlike Pennsylvania’s filing number they are not zero-padded: they are plain integers (e.g. 3400676484, not 0003400676). Pass the number exactly as it appears on the SoS portal.

Search Capabilities

Starts-with search. Name search anchors on the beginning of the legal name (case-insensitive). Use fuller query strings to narrow the result set, which is capped at 50 matches.

Quirks & Gotchas

Mappings

Legal form is sourced from the entity-type label on the Oklahoma Secretary of State Entity Summary page. The register uses a fixed vocabulary of entity types corresponding to Oklahoma statutes. Topograph maps each to a standardized category; the raw local name is always preserved.
The full list of standardized legal forms and their ISO 20275 mappings (where GLEIF publishes one) is available on the Oklahoma pricing page.

Officer Roles

Officer and director data comes from the PRINCIPALS table on the paid Entity Detail page. Titles are reported in uppercase by the register. Topograph maps the well-known vocabulary to standardized roles; unusual titles are enriched by AI and returned with the raw localName preserved.
Registered agents are returned under otherKeyPersons, not under legalRepresentatives. They hold the RegisteredAgent role and are available from the free company-data block.
