Data Sources

Colorado uses a single integration against the Colorado Secretary of State Business Database Search. The register covers every entity filed with the Secretary of State: corporations, foreign corporations, limited liability companies, nonprofit corporations, limited partnerships, limited liability partnerships, general partnerships, and cooperatives.

Colorado Secretary of State business database (live, authoritative). The public business database exposes legal name, 11-digit entity ID, status, entity form, formation date, jurisdiction, principal office address (street and mailing), and registered agent name and address. Data is read live from the official portal on each request.

Officers and managers are not filed. Colorado does not require business entities to file owner, officer, director, member, or manager information with the Secretary of State. That information is kept in the entity records at the principal office. The registered agent is returned as an other key person; legalRepresentatives is intentionally empty.

Search Capabilities

Search Type	Pattern	Example	Match Type	Expected Results

By Entity ID	11 digits	`19931121425`	Exact	Exact match returned first (`matchType: id`); other results may follow

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

Quirk	Details
Officers and managers are not available	Colorado law does not require entities to file owner, officer, director, member, or manager information with the Secretary of State. These fields are kept in the entity’s own records. `legalRepresentatives` is always empty for Colorado entities.
No shareholder or UBO register	Colorado does not publish shareholders or beneficial owners for any entity type. Federal FinCEN BOI records are separate and not publicly accessible.
Registered agent is an other key person	The registered agent is surfaced under `otherKeyPersons`, not under `legalRepresentatives`. It receives service of process and has no statutory authority to bind the entity.
No bulk dataset	No official bulk business-entity dataset or open data feed was found for Colorado. All data is returned live from the official portal on each request.
No activity codes	Industry classification codes are not published on Colorado Secretary of State business summary records.
Tax ID is separate	The Colorado SOS entity ID is not a tax ID. For federal EIN or Colorado state tax IDs, direct the entity to the IRS or Colorado Department of Revenue.
Free documents are bundled	The Trade Register Extract (printed current detail page) and the Formation Filing PDF are included at no extra charge with the company data block.
