Sources, coverage & methodology
Where the records come from, what they cover, and how to verify them.
Current coverage
2,000 selected SEC company profiles. Retrieved Nov 3, 2026. The New York active-entity snapshot adds 4,310,443 registrations, searchable by name and DOS number. Browse New York registrations. Other state coverage is listed separately.
| Source | Current use | Limitations |
|---|---|---|
| SEC EDGAR | Legal names, CIK, reported EIN, incorporation jurisdiction, locality, tickers, SIC, filing links. | Selected operating companies only. Most private businesses are absent. Foreign-incorporated entities are excluded from this initial collection. |
| U.S. Census Bureau | Simplified state boundaries, 2026 vintage. | Map navigation, not a legal boundary survey. |
| State authorities | Links to registration authorities. | New York, Connecticut and Colorado: organizational snapshots imported. Other state pages remain registry guides unless explicitly stated otherwise. |
Selection and freshness
Collection proceeds in bounded batches from the SEC ticker file, retaining operating entities with a U.S. incorporation jurisdiction. The collector resumes from its recorded position. This is a selective collection, not a representative sample or a ranking. Each profile shows its actual retrieval date. Collection and publication are separate steps; a new source record appears only after the static publication succeeds.
New York State Department of State
The official OPEN-NY active-entity snapshot supplies DOS registration number, legal name, entity type, initial New York filing date, county and recorded jurisdiction. We check for new snapshots nightly; the source publication frequency is monthly. A complete validated snapshot replaces the previous one atomically. Inclusion is not a current good-standing certificate. Street addresses, officers and agents are excluded. New York registrations use a separate jurisdiction-specific identifier and are not automatically merged with SEC profiles.
Connecticut Secretary of the State
455,308 Connecticut registrations from the Business Master dataset, designated Public Domain by its publisher. We retain active LLCs, stock and non-stock corporations, limited partnerships, LLPs and benefit corporations. Records without a usable business ID are excluded. The snapshot is checked nightly and replaced only after full validation. Business IDs retain leading zeros. Registration status is dated source information, not a current good-standing certificate. No street addresses, emails, officers or ownership-demographic fields are imported.
Colorado Department of State
2,231,168 Colorado registrations from the official Business Entities dataset, designated Public Domain. Selected corporate and limited-liability forms with non-dissolved source statuses are included. Status and type codes are reproduced as recorded, not certified. Source versions are checked nightly. Complete validated replacements add new records, update existing identities and remove records leaving the selected scope. Absence is not by itself proof of dissolution. An incomplete download or an unusually large loss of identifiers does not replace the existing snapshot. Privacy suppressions remain effective across imports.
Identifiers and matching
CIK values preserve leading zeros. EINs are reproduced only where the SEC record reports a nonzero nine-digit number; they are not verified against an IRS service. State registration numbers and LEIs are not inferred. SEC profiles are keyed by CIK; New York profiles by DOS number; Connecticut profiles by business ID; Colorado profiles by entity ID. Matching across registries requires separate evidence.
What we deliberately do not infer
- A SEC filing does not prove state good standing, solvency or a business license.
- Missing accounts do not prove that a company has no revenue.
- Industry SIC codes are not NAICS codes.
- No owner, director or beneficial-owner identity is inferred from a company name.
- Street addresses, personal contact details and consumer credit scores are not included.
Corrections and removal
Submit a correction or privacy request. Corrections to the originating register must also be addressed to that authority. OpenBase can restrict its own publication independently where appropriate. Removed profile IDs remain suppressed on subsequent imports.
Reuse and attribution
Link to the profile and its original source, preserve the collection date, and describe coverage accurately. Source material may have its own restrictions; public access is not a blanket license for every downstream use. Do not describe OpenBase content as government-certified.
