How to Find Certified Diverse Suppliers in Maine

MaineDOT is the certifying agency for Maine's DBE program and publishes the state's DBE directory on its civil rights page as a PDF updated weekly.

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.

Maine state directories

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

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 Maine 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.
