Data Sources

Iowa has two complementary integrations against the Iowa Secretary of State, Business Services Division.

Active Iowa Business Entities open-data extract (fast, non-authoritative). A weekly snapshot published at data.iowa.gov. Covers approximately 335,000 active domestic and foreign entities: legal name, entity type, registration date, principal-office address, and registered agent. Officers and directors are not included in this extract. Used for sub-second onboarding lookups.
Iowa SoS business search portal (authoritative). A live read from the sos.iowa.gov public business search. Returns authoritative entity status, the full officer roster (Name, role, Director flag, and address for each officer), the verified principal-office address, and the registered agent. Covers all entities in the Iowa register, including the approximately 265,000 dissolved, terminated, or withdrawn entities that are absent from the weekly open-data extract. The Trade Register Extract (a printed PDF of the SoS entity summary page) is bundled with this tier at no extra charge.

Mode-based routing. Onboarding requests (mode: "onboarding") are served from the weekly open-data extract (fast, no live status, no officers). Verification requests (mode: "verification") read the Iowa SoS portal live for authoritative status, the full officer roster, and the Trade Register Extract. Dissolved or terminated entities are only reachable through verification mode.

Active-only open-data extract. The weekly Iowa SoS open-data dataset covers only active entities (~335k of approximately 600k total). Entities that have dissolved, terminated, merged, or withdrawn are removed from the feed rather than tagged. They are invisible in onboarding mode and only resolvable through verification mode.

Company Identifiers

Query Identifiers

Identifier Type	Format	Example	Notes
Iowa Business Entity Number	6 digits, numeric only, leading zeros preserved	`084726`	Assigned by the Iowa Secretary of State, Business Services Division.

The Iowa Business Entity Number is always exactly 6 digits with leading zeros preserved. Queries using the unpadded form (e.g. 84726 instead of 084726) are rejected. The register and our API treat them as different keys.

Identifiers in API Response

Identifier	Format	Example	Found In
`corpNumber`	6 digits, zero-padded	`084726`	All entities

Search Capabilities

Search Type	Pattern	Example	Match Type	Expected Results
By Name	2–100 chars	`"Hy-Vee"`	Starts-with (case-insensitive)	Multiple results, capped at 50
By Iowa Business Entity Number	6 digits	`019862`	Exact	Exact match returned first (`matchType: id`)

Name search anchors on the beginning of the legal name. Use fuller query strings to narrow the result set. Inactive entities are not present in the open-data index and are surfaced through the live portal fallback. For complete coverage by name (including dissolved entities), use verification mode.

Quirks & Gotchas

Quirk	Details
Leading zeros are load-bearing	Iowa Business Entity Numbers are always 6 digits with leading zeros preserved. `084726` and `84726` are treated as different keys. Never strip leading zeros.
Onboarding mode returns no officers	The weekly open-data extract does not include officer or director information. Officers, Director flags, and per-officer addresses are available only in verification mode via the live SoS portal.
Active-only extract misses ~265k entities	The open-data dataset is an active-only snapshot. Dissolved, terminated, merged, and withdrawn entities are excluded. Verification mode is the only path to reach them.
No shareholder or UBO register	Iowa does not publish shareholders or beneficial owners for any entity type. The SoS portal has no shareholder or UBO section.
No activity codes	Industry classification codes (NAICS, NACE, ISIC) are not collected by the Iowa Business Services Division.
”Doing business as” names are county-level	DBA filings in Iowa are recorded at the county recorder level and are not aggregated in the state-level open-data dataset. Fictitious names filed with the Secretary of State appear on the live portal but are not returned as a separate datapoint.
Officer Director flag	The live SoS portal includes a separate Director (Yes/No) column on each officer record. This flag is preserved on each legal representative in the API response.

Mappings

Legal Forms

Iowa legal form is sourced from the corporation type published in the Iowa Secretary of State open-data dataset and the live portal. The vocabulary is a closed set of 32 values drawn from the Iowa Code, covering entity types across Title XII (Business Entities) and associated chapters. Each value is mapped to a standardized Topograph category and, where available, an ISO 20275 ELF code. The full searchable table of all 32 Iowa legal forms with standardized mappings and ISO 20275 codes is available on the Iowa pricing page.
