# RegistryAtlas

> RegistryAtlas is a US business-records lookup hub: how to search each state's business entity
registry, EIN lookup for SEC-registered companies (EDGAR) and nonprofits (IRS 990 data) plus
guidance for finding your own EIN, and NAICS/SIC/nonprofit reference tools. It is an independent
reference site over official public records — not a government agency; the state registry, SEC
EDGAR, or the IRS is always the authority. There is no public IRS reverse-EIN-by-name lookup, and
RegistryAtlas never claims one.
