Data Availability

API access: US-KS is not yet part of the public countryCode enum. Contact us to enable it on your workspace. Requests sent with countryCode: "US-KS" will otherwise return 400 until the enum is expanded.

Data Sources

Kansas uses a single integration against the Kansas Secretary of State Business Entity Search Station (sos.ks.gov), maintained by the Business Services Division. The register covers every domestic and foreign entity filed under the Kansas General Corporation Code (K.S.A. Chapter 17) and the Limited Liability Company Act (K.S.A. Chapter 17, Article 76): for-profit and not-for-profit corporations, LLCs (including series and professional variants), limited partnerships, limited liability partnerships, and business trusts.

Kansas Secretary of State Business Entity Search Station (live, authoritative). The public portal is queried in real time for every request. It exposes legal name, Business ID, entity type, formation date, jurisdiction, current status, principal office address, resident agent name and address, last reporting year, next report due date, forfeiture date when applicable, and the full filing history.

Single live source. Kansas does not publish a bulk download or open-data feed of the business register, so every request is served from the live portal. Because that read is fast, both onboarding and verification modes return the same authoritative data — there is no separate non-authoritative cache tier.

Portal reliability. The Kansas Secretary of State portal may be temporarily unavailable during maintenance windows or periods of high load. The flakySource caveat on the data block reflects this. Failed requests are not billed.

Quirks & Gotchas

Quirk	Details
Numeric Business ID only	The Kansas SoS Business ID is always a numeric string with no dashes or spaces. Non-digit characters are rejected. It is distinct from the Federal Employer Identification Number.
No bulk / open-data feed	Kansas does not publish a Socrata, CSV, or API bulk download of the business register. Every request hits the live portal.
Officers not on the public detail page	Officers and directors are filed on the Kansas annual information report (Form IFP) but are not surfaced as a structured datapoint on the public Business Entity Search Station. They are not available via the API.
Resident agent is an other key person	The resident agent name and address are returned under `otherKeyPersons`, not `legalRepresentatives`. The resident agent receives service of process but does not have authority to bind the entity.
No activity codes	Industry classification codes (NAICS / NACE / ISIC) are not collected by the Kansas Secretary of State.
No shareholders or UBOs	Shareholder lists and LLC member names are not collected by the register. Kansas does not maintain a public beneficial-ownership register. Federal FinCEN BOI records are restricted.
Sole proprietorships and DBAs excluded	Sole proprietorships, doing-business-as filings, assumed names, fictitious names, and trade names do not file with the Kansas Secretary of State and are not indexed for search.
Certificate of Good Standing is a paid upgrade	The official Kansas Certificate of Good Standing is available as a paid document (see pricing). The Trade Register Extract is included with the company data at no extra charge.

Mappings

Legal Forms

Legal form is sourced from the entity-type label published by the Kansas Secretary of State Business Entity Search Station. The taxonomy is a closed enum based on entity types registered under K.S.A. Chapter 17 (Kansas General Corporation Code) and K.S.A. Chapter 17, Article 76 (Limited Liability Company Act). The full list of legal forms with ISO 20275 mappings is available on the pricing page. The table below shows the most common forms.

All Kansas entity types

Kansas Entity Type	Standardized	ISO 20275
For-Profit Corporation	Corporation	`C3JQ`
Professional Association	Corporation
Public Benefit Corporation	Corporation
Not-For-Profit Corporation	NonprofitOrganization	`4RCO`
Foreign For-Profit Corporation	Corporation
Foreign Not-For-Profit Corporation	NonprofitOrganization
Limited Liability Company	LimitedLiabilityCompany	`JY0X`
Series Limited Liability Company	LimitedLiabilityCompany
Professional Limited Liability Company	LimitedLiabilityCompany
Public Benefit Limited Liability Company	LimitedLiabilityCompany
Foreign Limited Liability Company	LimitedLiabilityCompany
Limited Partnership	Partnership	`T91T`

Limited Liability Partnership	Partnership

General Partnership	Partnership
Business Trust	Other
Foreign Business Trust	Other

Company Statuses

Status is read directly from the Kansas Secretary of State Business Entity Search Station and reflects the entity’s current lifecycle state under K.S.A. Chapter 17.

Status	Notes
Active And In Good Standing	Current on annual reports; no outstanding obligations
In Good Standing	Variant of the active / good-standing state
Active	Active without explicit good-standing qualification
Forfeited - Failed To Timely File AR	Annual report delinquency; entity has forfeited its rights to do business
Forfeited	General forfeiture state
Dissolved	Voluntarily or administratively dissolved
Cancelled	Applicable to partnerships and similar forms
Merged	Entity merged into another
Withdrawn	Foreign entity withdrew its registration
Inactive	No longer active; catch-all for legacy records

Statutory Filings

Kansas entities file an annual report confirming the entity’s particulars are current. The register publishes “Next Report Due Date” and “Last Reporting Year”, returned on the cross-country statutoryFilings field as next.dueDate and lastFiled.year.

{
  "statutoryFilings": {
    "annualFiling": {
      "cadence": "annual",
      "next": { "dueDate": "2026-08-15" },
      "lastFiled": { "year": 2025 },
      "source": "ks_sos"
    }
  }
}

US states publish no statutory accounts, so the accounts obligation is absent rather than returned empty. An empty object would read as “we looked and found nothing”, which is a different claim. Placeholder cells such as N/A or Inactive, Not Applicable are dropped rather than parsed as dates, so an entity with no obligation simply has no statutoryFilings.
