Every state maintains a free corporate registry search, almost always under the Secretary of State — and it's the single fastest way to verify a business is real, find its registered agent for service of process, or trace its officers. There is no national registry: a company is searched in each state where it's registered or foreign-qualified.

How the States Differ
The office varies in a handful of states: Arizona uses the Corporation Commission, Michigan runs LARA, Wisconsin the Department of Financial Institutions, Maryland SDAT, Hawaii DCCA, and Virginia the State Corporation Commission. Several states also brand the portal — Florida's Sunbiz, Nevada's SilverFlume, Tennessee's TNBear, Louisiana's geauxBIZ, Wyoming's WyoBiz — which is why a Google search sometimes beats guessing the agency name.
Coverage differs too: some registries show full filing images and officer histories free, others show status only and charge for documents. The state guides note what's free where.
