CAGE Codes for Department of Energy
~$35B in annual federal contracts
About DOE Contracting
DOE manages the US nuclear weapons stockpile, national laboratories (like Sandia, Oak Ridge, and LLNL), and a large portfolio of clean energy R&D. Most DOE work flows through Management & Operating (M&O) contracts with large primes, but thousands of subcontractors and small businesses also need CAGE codes to participate in the DOE supply chain.
Like all federal agencies, DOE 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 DOE.

CAGE Code Requirements for DOE Vendors
To sell to Department of Energy, 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 DOE should also complete any applicable SBA certifications (8(a), WOSB, SDVOSB, HUBZone) — these are linked to your CAGE code record in SAM.gov.
