How to Find Certified Diverse Suppliers in Missouri

Missouri's Office of Equal Opportunity certifies minority- and women-owned businesses for state contracting, and its MBE/WBE directory is public and searchable.

Missouri state directories

Start with the official state directory. It lists firms Missouri has certified, and it is the source public buyers and prime contractors use to confirm a firm counts toward state and federally funded contract goals.

Federal set-aside firms in Missouri

For federal contracts and subcontracting plans, search SAM.gov and filter by location and socioeconomic status: 8(a), Women-Owned Small Business (WOSB), Service-Disabled Veteran-Owned (SDVOSB), and HUBZone. These are separate from the state and council certifications above, and buyers count them differently.

Verify before you rely on a certification

A certificate on its own is not proof. Before you count a Missouri supplier toward a diverse spend goal or a subcontracting plan:

  1. Confirm the record is active, not expired, in the issuing directory above.
  2. Check the certification type matches what your program counts. MBE, DBE, WOSB, and CBE are not interchangeable.
  3. Keep a dated screenshot or export of the directory record for your compliance file.
