Mississippi Business Entity Search
By Edmond Hui · Last updated October 5, 2026
The short answer. The Mississippi Secretary of State (Business Services) keeps Mississippi's register of business entities. The official search is the state's “Business Search” page, on corp.sos.ms.gov. We have not confirmed whether the state charges to search, so check the search page itself.

Some of Mississippi's pages could not be read directly, so several answers here are marked not confirmed. Check them on the state's own search page.
How to Search Mississippi's Register
The official search is the state's “Business Search” page, on corp.sos.ms.gov. We have not confirmed whether the state charges to search, so check the search page itself. Open the official search.
On the main search page you can search by:
- Entity name
- Entity or filing number
- Officer or principal
- Registered agent or registered office
What a Search Result Shows
We have not confirmed what a Mississippi search result shows; check the search page.
What Each Mississippi Status Means
The status is the label the register puts on each entity. Where the state defines a label, the meaning below restates that definition, with a link to the state page it comes from. Where it does not, we do not guess from the word, because the same word can mean different things in different states.
We have not confirmed which status labels Mississippi's register uses; check the search page for an entity's status and what it means.
If the search shows that your own LLC was dissolved, see how to reinstate an LLC in Mississippi.
A search result is not a certificate of good standing. If a bank or another state asks for one, see how to get a Mississippi certificate of good standing.
Viewing and Ordering Documents
Filed documents can be viewed online. We have not confirmed whether viewing them is free.
We have not confirmed what copies or certified copies cost; check the search page or the filing office's fee schedule. Order copies from the state.
Is the Name Available?
We have not confirmed how Mississippi wants you to check whether a name is available.
We have not confirmed whether Mississippi requires a name reservation before you file. A name reservation costs $25.00.
Our free LLC name checker looks up domain and social media handle availability for a name. It does not search Mississippi's register, so check the state's search as well.
Bulk Business Entity Data
Mississippi offers bulk business entity data free of charge. The Secretary of State's free Mississippi Business Reports service lets you search the corporations database and export up to 300,000 results to Excel. For a full export, the office asks you to contact Business Services. See the state's bulk data page.

Frequently Asked Questions
This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state's business entity filing office publishes about searching its register, with the sources this page cites. It cannot tell you whether a particular business is active, authorized or reliable: read the state's own record for that, and search tools, status labels and fees change between our reviews. Confirm anything you rely on with the filing office named on this page before you act on it.
