Per American Recovery and Reinvestment Act and Federal Funding Accountability and Transparency Act federal regulations, subcontractors receiving federal contracts must have a Data Universal Numbering System number and be registered in the System for Award Management, a new online system that includes functionality from Central Contractor Registration, Federal Regulations, the Excluded Parties List System, and the Online Representations and Certifications Application.

Additionally, representations and certifications are required if the solicitation to which you are responding requires that you have an active registration in SAM. Representations and certifications are now entered in SAM.

Sellers doing business with Y‑12 must have a DUNS number and maintain active registration in SAM.
