Direct registry access

Every record links back to the official Secretary of State or SEC source.

Unified schema

Standardized fields across 51 jurisdictions for fast comparison.

Verified status

Active, inactive, and dissolved entities flagged with confidence scores.

Corporations vs. LLCs

Corporations have a more formal governance structure — boards, officers, shareholders — and different tax treatment than LLCs. Our search filters by entity type so you can target just C-corps and S-corps, or include all entity forms.

Public companies included

Public corporations are cross-referenced with SEC EDGAR, so you can jump straight from a corporation record to its 10-K, 10-Q, and 8-K filings.

What you'll find

Legal name, jurisdiction, filing number, CIK (where applicable), entity status, incorporation date, registered agent, and registered office address.

Frequently asked

Can I distinguish C-corps from S-corps?+

S-corp status is a federal tax election and isn't always reflected in state filings. We surface the data the state publishes; tax classification often requires the corporation's own disclosure.

Are foreign corporations included?+

Foreign-qualified corporations (registered to do business in additional states) appear under each state where they've qualified.

Can I export corporation lists?+

Yes, with a premium account. Free accounts can browse and view individual records.
