Heads up
Wisconsin's federal DBE certification runs separately through WisDOT, and its certified-firm data sits in the login-based Civil Rights and Compliance System rather than a public directory. WisDOT is not currently accepting new DBE/ACDBE or interstate applications under the USDOT Interim Final Rule issued October 3, 2025; only recertification and reevaluation submissions are open. Confirm a firm's current status before relying on it.
Wisconsin state directories
Start with the official state directory. It lists firms Wisconsin 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.
Wisconsin Supplier Diversity Program Certified Firm Search
The Department of Administration's search of every certified MBE, WBE, and DVB firm, filterable by products and services, NIGP, NAICS, and construction division codes, plus city and county.
Open the directory ↗North Central Minority Supplier Development Council
The regional National Minority Supplier Development Council affiliate serving Wisconsin. Corporate buyers source certified Minority Business Enterprises (MBEs) through its network.
North Central Minority Supplier Development Council ↗Federal set-aside firms in Wisconsin
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 Wisconsin supplier toward a diverse spend goal or a subcontracting plan:
- Confirm the record is active, not expired, in the issuing directory above.
- Check the certification type matches what your program counts. MBE, DBE, WOSB, and CBE are not interchangeable.
- Keep a dated screenshot or export of the directory record for your compliance file.
