Step-by-step
- 1
Know which register holds the record
In United States, company records sit on SEC EDGAR. Trade directories and aggregator sites are copies — the register is the source of truth.

Search by name or registration number
A registration number returns exactly one entity. A name may return several, especially for groups using the same brand across entities.
- 3
Read the register entry, not the marketing page
The register entry shows Company name and EIN, State of incorporation. That is what a bank, auditor or counterparty will check.

Keep a dated copy
Register entries change. Save the record with the date you retrieved it, or set up monitoring so you are told when the entry changes.
Frequently asked questions
Is the United States company register free to search?

Do register entries stay accurate?
Only until the company files its next change. Directors, addresses and status can change without notice, which is why a dated copy — or automatic monitoring of the entry — matters for anything contractual.

For public companies, search SEC EDGAR by company name to find filings like 10-K annual reports and 8-K material events. For private companies, you'll need to search the specific state's Secretary of State website where the company is incorporated.
