Company data here comes directly from Colorado Secretary of State — Business Organizations.

One of the jurisdictions under United States, whose page lists the others and covers the national register separately.

What you can call here

What each operation does is the same everywhere and is explained on the jurisdictions overview.

Operation	Status
Autocomplete	Live
Company search	Live
Company report Includes: Registered details and Legal representatives.	Live
List documents	Live

Prefill	Live

Start with company search and jurisdictionCode: "us-co". Pass the name as companyName, a registration number as companyNumber, or both to narrow the result. Here companyNumber is read as entityId.

Fields

To say exactly what you mean, send an advancedQuery instead. Colorado (US) understands these fields:

Field	What it does
`name`	Entity name to search for.
`entityId`	Colorado SOS entity ID (11-digit numeric) to search for.

Examples

{  "jurisdictionCode": "us-co",  "advancedQuery": {    "name": "Molson Coors"  }}

Colorado (US) also accepts entityId.

Company identifiers

Search by passing the registration number as companyNumber — it is matched against the schemes this register can search on, so you do not name the scheme yourself. Not every scheme below is searchable; the rest label the values returned in a company’s identifiers.

Identifier	Appears as	Format
CO Entity ID Colorado Secretary of State business entity ID number, an 11-digit numeric string whose leading four digits encode the filing year (e.g. '19871012497', '20251665680'). A single legacy record carries 10 digits. Used as the primary key across every Colorado open-data business dataset.	`us_co_entity_id`	`^[0-9]{10,11}$`

Documents you can order

Document	Status
US-CO SOS Document Filed-document image (PDF) retrieval for Colorado entities from the Colorado Secretary of State, identified by a kausateDocumentId from the document list.	Live

These are filings whose availability differs per company: call list documents first and order the ID it returns.

Local notes

Gotchas

Trap	What happens
Delinquent is the largest bucket	"Delinquent" is Colorado's largest status bucket, ahead of "Good Standing" — the company is still active, just missed a periodic report. Don't filter it out as closed.
Registered agent only	Colorado tracks only the registered agent — no officer, director, member, or shareholder data. The legal representatives list holds at most one entry, not actual management or ownership.
Foreign entities lose formation data	For a "foreign" entity (formed elsewhere, registered to do business in Colorado), the report omits incorporation date and original state or country of formation — only the Colorado registration date is shown. Domestic entities do get an incorporation date.
Agent role code is partial	The registered agent's role code is populated only for LLCs and for-profit corporations (~85% of the register). Other entity types return the name "Registered Agent" with no code — detect the role by name, not code.
Older filings may be missing	Filing history reach varies — long-established companies may be missing older filing events even though current details are up to date. Don't assume the document list is complete.

Glossary

Term	Meaning
`Delinquent`	A company can carry this status while still being fully active: it means a periodic report was missed and the company lost its good-standing status, but it still legally exists and can cure the delinquency and be restored to good standing at any time. It is not dissolved or closed.
`Noncompliant`	The company failed to maintain a registered agent — a compliance defect, not an end to its legal existence. The company still exists and can cure the issue.
`Registered Agent Resigned`	The company's registered agent has resigned and the company must appoint a new one, but the company itself still legally exists.
`Exists`	Colorado uses this status for entity types that have no periodic-report requirement — such as ditch and water companies, and corporations sole. It simply confirms the entity is currently in force.
