About DOT Contracting
DOT includes the FAA, Federal Highway Administration, Federal Transit Administration, and other modal agencies. It funds and awards contracts for aviation systems, highway construction, transit infrastructure, and transportation research. All DOT vendors need a valid CAGE code and active SAM registration.
Like all federal agencies, DOT requires every vendor and subcontractor receiving direct government payments to hold an active CAGE code and a current SAM.gov registration. The CAGE code uniquely identifies your company in the federal procurement system and appears on all contract actions, invoices, and vendor records. Without it, you cannot receive an award or payment from DOT.

CAGE Code Requirements for DOT Vendors
To sell to Department of Transportation, every vendor — from large prime contractors to small businesses and subcontractors receiving direct government payments — must have:
- An active CAGE code assigned by DLA through SAM.gov
- An active SAM.gov registration (renewed annually)
- A valid UEI (Unique Entity Identifier)
- A completed Representations & Certifications section in SAM.gov
Small businesses pursuing set-aside contracts with DOT should also complete any applicable SBA certifications (8(a), WOSB, SDVOSB, HUBZone) — these are linked to your CAGE code record in SAM.gov.
