What is a government contractor?

A government contractor is a private company or individual that provides goods, services, or construction to the federal government under a formal contract. Contractors receive a Unique Entity Identifier (UEI) and are listed in the federal procurement system.

How do I become a federal contractor?

Register your business to obtain a UEI, identify your relevant NAICS codes, and use SamSearch to monitor solicitations matched to your capabilities — with AI-powered alerts so you never miss an opportunity.

What is the difference between a prime contractor and a subcontractor?

A prime contractor holds the direct contract with the government. A subcontractor performs work under the prime's contract. SamSearch's directory focuses on prime awardees and helps you identify teaming or subcontracting partners.

How often is this contractor data updated?

SamSearch refreshes contractor award data daily. Entity registration details are synced regularly so profiles stay current.

Can I find small business contractors here?

Yes — the directory includes all award sizes. Use SamSearch's advanced filters to narrow by set-aside type (8(a), WOSB, SDVOSB, HUBZone, etc.) and award threshold.
