US Business Entities

Query the System for Award Management (SAM.gov) registry by business name. Returns UEI, CAGE code, NAICS codes, registration status, expiration date, and address — all in a single API call.

What SAM.gov Is

SAM.gov (System for Award Management) is the official US government registry for entities that do business with the federal government. Any company receiving a federal contract, grant, or loan must be registered in SAM.gov. The database contains over 700,000 active registrations and is updated daily.

SAM.gov records are the authoritative source for:

  • UEI (Unique Entity Identifier) — the government's primary business ID, replaced DUNS in 2022
  • CAGE Code — NATO-standard entity identifier used in defense and government procurement
  • NAICS Codes — industry classification codes indicating what the entity does
  • Registration status and expiration — confirming whether a business is currently eligible for federal contracts
  • Entity type — corporation, sole proprietor, partnership, government entity, etc.

Who Uses This

  • Government contractors — verify subcontractors and vendors are SAM-registered before engaging them
  • Grant administrators — confirm recipient eligibility before disbursing funds
  • Procurement officers — quickly check if a company is registered and active without logging into SAM.gov
  • Compliance teams — cross-reference business names against the federal registry as part of KYB (Know Your Business) workflows
  • Business intelligence platforms — enrich company data with official government registration details

Why This API vs. Direct SAM.gov Access

SAM.gov's direct API requires registration, API key management, and navigating a complex nested JSON response structure that changes without notice. This API normalizes the SAM.gov response into a consistent, developer-friendly schema — no authentication to SAM.gov, no schema parsing, no rate-limit management on your end.

The cache refreshes every 24 hours against the live SAM.gov database. Results are typically available within one business day of any registration change.
