About Us
A simple, fast way to find the right business entity search for any state.
Published and maintained by Sumo Coder
SOS Business Search is an independent directory 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
Every filing fee, search link, and requirement on this site is compiled from official sources — each state's Secretary of State or equivalent agency directly — rather than written from scratch. Every state page links directly to that state's official site so you can check the primary source yourself.
Each state page and guide shows an "Updated" date. That date reflects when the page was last checked against its official source and corrected if anything had changed — it isn't a cosmetic timestamp.
Filing rules and fees vary by state and change over time. If something on this site doesn't match what your state's official site currently says, the state's site 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.
Corrections
