Using Mississippi corporate search and STAR UCC
Business entity lookup runs on corp.sos.ms.gov. UCC search and filing use the Secretary of State STAR portal on business.sos.ms.gov under Uniform Commercial Code. The linked entry opens standard UCC search; the same UCC area lists non-standard search, file number search, and UCC-11 certification information.

UCC information
Financing statements & lien search
UCC search (standard and related searches)
Standard search matches Revised Article 9 logic for organization or individual debtor fields. When standard search does not return what you expect, use non-standard search or file number search from the same UCC portal navigation. UCC-11 search certification uses the PDF form the division links from the UCC pages.
Tips if the site feels confusing
- corp.sos.ms.gov and business.sos.ms.gov are different hosts; entity search does not open the UCC index, and the reverse is also true.
- Pick standard versus non-standard search based on how the debtor name was filed; file number search helps when you already have the SOS file number.
- Official fees, certified search rules, and forms belong to the Mississippi Secretary of State and your advisors, not third-party summaries.
Educational overview only. Proof of Good Standing is not a government agency. Confirm fees, forms, and requirements on the Mississippi Secretary of State before you file or rely on search results.
