Not a government site
EntityCheck.org is run independently and is not affiliated with, endorsed by or connected to any Secretary of State, corporation commission, the IRS, the SEC or any other government body. Only the agency that keeps a register can confirm a record, accept a filing or issue a certificate. Each state guide links to that agency.
No legal, tax or financial advice
Our guides explain how public records work. They are not advice about your situation. Choosing a state, an entity type or a name has legal and tax consequences; for those decisions, speak with a licensed attorney or tax professional in the relevant state.
What each tool can and cannot tell you
| Tool | Useful for | Cannot do |
|---|---|---|
| Name check | Spotting existing names and close variations | Reserve a name or promise the state will accept it |
| Live results (open data or data provider) | A quick look at matching records | Replace the official record, which can be newer than any copy |
| EIN checker | Checking format and IRS prefix; finding nonprofit and SEC filer EINs | Prove a private company owns a given EIN |
| Fee directory and cost tables | Comparing states before you file | Guarantee current fees; agencies change them, as Louisiana did on October 1, 2026 |
Accuracy and updates
We take facts from official sources and log every change on the data updates page, but errors and outdated values are possible. Confirm fees, deadlines and requirements with the agency before you file or rely on them. How we check facts is described on the about page.
Links to other sites
We link to government and third-party websites we do not control. Their content, availability and privacy practices are their own.
