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 paid Entity Detail returns legalRepresentatives and non-representative principals in otherKeyPersons.
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.

Identifiers in API Response

GLEIF is the supplementary data source for this identifier. company.identifiers.lei is returned when a company identifier has a unique match against this jurisdiction’s registration or validation references in GLEIF. An LEI (Legal Entity Identifier) has 20 uppercase letters and digits, ending in two check digits. Coverage varies by entity. The field is omitted when no unambiguous match is available. Lapsed or retired LEIs may be returned; annulled records are excluded.

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 200 matches.

Active companies only

Search can return companies that are no longer active. Each result carries the register’s status, so activeOnly=true removes the inactive ones.

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 returns the label as-is in legalForm.localName, without a standardized category.

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. Other titles are returned with the raw title in localName and no standardized role. Executive offices and management functions retain their office meanings; governing-only directors, ordinary members, limited partners and formation actors are returned as otherKeyPersons from the Entity Detail product. Corporate officer powers depend on the bylaws or board resolution. An LLC manager’s authority depends on the governing documents and the particular act; no individual signing mode is inferred from the title.
Registered agents are returned under otherKeyPersons, not under legalRepresentatives. They hold the Registered Agent role and are available from the free company-data block.
