About GSA Contracting
The GSA Multiple Award Schedule (MAS) is the gateway to selling to every federal agency. To get a GSA Schedule contract, you must have an active CAGE code and SAM.gov registration. GSA also manages Federal Buildings and fleet operations. GSA Schedule vendors can sell to DoD, civilian agencies, and state/local governments under cooperative purchasing agreements.
Like all federal agencies, GSA 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 GSA.

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