Using Missouri business entity search and UCC (Secretary of State)
Public business entity search runs on bsd.sos.mo.gov in the business registration system. UCC filing, search, and related resources are organized from www.sos.mo.gov/ucc. The BSD site can switch you into the UCC filing area; bookmark both the entity search URL and the UCC hub when you move between charter and lien work.

Missouri business entities & Secretary of State workflows
Search for a business entity
Search by business name, registered agent, name availability, or charter number as the form allows. Exact match behavior may require corporate suffixes and punctuation as the Secretary of State describes; other match modes often work better without those tokens. Filter to active corporations only when that option fits your task.

UCC information
Financing statements & lien search
UCC filing and search
Start at the Secretary of State UCC hub for links into search, filing, and forms the division publishes. Some workflows continue on bsd.sos.mo.gov when you use the on-screen control to switch from business registration to the UCC filing section. Read UCC-specific help and fee notices on the official pages before you rely on screen output.
Tips if the site feels confusing
- Entity search on bsd.sos.mo.gov and the UCC hub on sos.mo.gov are different entry points; use the UCC hub (or the BSD switch to UCC filing) for lien index and UCC filings.
- Exact match name search may need Inc., LLC, or punctuation exactly as filed; try includes or starting-with modes when exact match returns nothing.
- Official fees, certified search rules, and filing deadlines belong to the Missouri 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 Missouri Secretary of State before you file or rely on search results.
