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.

SOS information

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.

Fees, forms, FAQ, and online filing links appear in the business registration menu on the BSD pages when you need the next step beyond search.

File or manage business registrations

Use Business Registration online filing and related links from the BSD portal or sos.mo.gov. Sign in through MY ACCOUNT when the workflow requires it, and follow the published fee schedule before you pay.

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.

Form a business

Starting a business in Missouri

Entity search on this page helps you verify names and good standing. When you are ready to form a new LLC, corporation, or nonprofit, use the same next steps we link from Business Lookup: confirm the name on the official register, choose a structure with your CPA or attorney if needed, then file through the state agency (and plan for publication, registered agent, and any industry licenses that apply).

Typical state filing fees

These amounts can change when agencies update their fee schedules. Double-check the current fee list, forms, and deadlines on the official Missouri business filing site yourself before you pay or submit anything.

LLC filing (state): $50
Corporation filing (state): $58
