How to Find Certified Diverse Suppliers in Iowa

The Iowa Department of Transportation certifies DBEs for the state and maintains the official directory of certified firms, updated as certifications are approved.

Heads up

Verify DBE status carefully right now: under the USDOT Interim Final Rule issued October 3, 2025, existing DBE and ACDBE certifications are being re-evaluated and may not be counted toward contract goals until a firm is recertified. Confirm a firm's current status before relying on it.

Iowa state directories

Start with the official state directory. It lists firms Iowa 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.

Iowa DOT DBE Directory

The Iowa DOT's searchable directory of certified DBE firms, maintained under 49 CFR 26.31, lists each firm's contact details and the NAICS work types it is certified to perform, with additions and removals applied as they are approved.

Federal set-aside firms in Iowa

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 Iowa 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.
