SOS Business Search is published and maintained by Sumo Coder, an independent publisher of consumer information resources. This site was built for one purpose: helping people quickly find the official business entity search tool for any U.S. state. We link directly to each state's Secretary of State (or equivalent agency) lookup tool and walk through how to use it, organized by state so you don't have to hunt for the right page.
Every guide covers the details people actually need — which agency runs the search, what you can search by, and where to go for filing fees, licensing, and registered agent requirements. When a state's process has quirks, we call them out plainly so you know what to expect before you start.
We also publish a small set of general reference guides covering common business filing topics — certificates of good standing, LLC dissolution, UCC filings, and registered agents — so you can get a quick answer without leaving the site.
How we source and verify information
Sourced from primary documents
Every filing fee, search link, and requirement is compiled directly from official state sources — never written from general knowledge. Every state page links to its official site so you can verify it yourself.
Dated and re-verified
Every state page and guide shows an "Updated" date — when it was last checked against its official source and corrected if anything changed. It isn't a cosmetic timestamp.
Independent, not government-run
We're a small independent team, not a law firm or government contractor. Your state's Secretary of State office is always the authoritative answer for your specific situation.
What we are not
SOS Business Search is not affiliated with, endorsed by, or operated by any state government or Secretary of State office. We're an independent publisher, and our guides are compiled and maintained separately from any official state system. For official business — filing paperwork, paying fees, or checking entity status — please visit the relevant state's official website.
Nothing on this site is legal advice. It's a starting point for understanding a state's filing process and finding the right official tool — not a substitute for guidance from your state's Secretary of State office or a qualified attorney.
