System for Award Management is the official, free online registrant database for the US federal government. SAM collects, validates, stores, and disseminates data in support of agency acquisition and award missions.
To be eligible to register in SAM, you must have a Data Universal Numbering System (DUNS®) number. The DUNS number is assigned by Dun & Bradstreet,
Inc. to identify unique business entities.
Update: the federal government has recently issued a contract to replace the use of the private D&B number with a new government owned SAM Managed Identifier or SAMMI. The GSA is managing this conversion and will be announcing shortly the "transition process" that will take place. Please watch for details!
If your business doesn’t already have one, obtain a D&B DUNS number online. D&B can be reached at 1-866-705-5711. Please note: You must wait 24 to 48 hours after obtaining your D&B
DUNS number before starting to register in SAM.
