Which organization requires vendors to register in SAM at least once a year?

The requirement for vendors to register in the System for Award Management (SAM) at least once a year is primarily enforced by the Department of Defense (DoD). This regulation is crucial because the DoD engages with a substantial number of contractors for various services, supplies, and construction projects. Vendor registration in SAM helps ensure that businesses interested in contracting with the DoD meet necessary eligibility criteria, are in compliance with federal regulations, and maintain updated information that aides in streamlined procurement processes.

The annual registration requirement facilitates the acquisition of accurate vendor data which is essential for both accountability and transparency in government contracting. The DoD emphasizes this requirement as part of its broader efforts to ensure that taxpayer dollars are spent wisely and that contracts are awarded to legitimate and capable vendors.
