SAM.gov registration is the mandatory front door to federal contracting—no registration, no eligibility to be paid by the government. The System for Award Management (SAM) is also where buyers and prime contractors find vendors and where contract opportunities are posted. This guide covers how to register as a government contractor, what to prepare first, and how to search SAM.gov effectively.
What is SAM.gov?
SAM.gov (the System for Award Management) is the official, free U.S. government website where businesses register to do business with federal agencies, obtain a Unique Entity ID (UEI), and search posted contract opportunities. For a deeper background, see our overview of what SAM.gov is.
What you need before you register in SAM.gov
- Your legal business name and physical address (must match IRS and bank records)
- Taxpayer Identification Number (TIN/EIN)
- Your bank routing and account numbers for electronic payment
- The NAICS codes that describe your business
Note: the UEI has replaced the old DUNS Number, and it is now assigned directly within SAM.gov.
How to register as a government contractor in SAM.gov
- Create a Login.gov account and sign in at SAM.gov.

How to search for contracts on SAM.gov
Use the “Contract Opportunities” search and filter by your NAICS code, set-aside type, place of performance, and posted date. Save searches and set email alerts so new solicitations that match your codes reach you automatically. Searching by NAICS is the single most effective filter—which is why choosing the right codes matters so much.
Common SAM.gov registration mistakes
- Business name or address that does not exactly match IRS/bank records (the top cause of rejection)
- Letting registration lapse—SAM registration must be renewed every 12 months
- Selecting too few NAICS codes and missing relevant opportunities
From SAM.gov to a GSA Schedule
SAM registration makes you eligible; a GSA Schedule makes you easy to buy from. If you are pursuing set-aside work, pair your registration with the right certifications—such as the Women-Owned Small Business program.
