UEI lookup
Look up a UEI and check the SAM.gov record
Paste a Unique Entity ID to verify whether the SAM.gov registration is active, when it expires, which CAGE code is attached, and whether public exclusions are present.
SAM.gov registration and renewal are FREE at sam.gov. The U.S. Government never charges you to register, renew, or update a SAM.gov registration.

What the UEI unlocks
The UEI is the cleanest key for a public SAM.gov record. It lets you verify registration status, expiration, CAGE code, physical location, NAICS/PSC profile and active exclusions.
When to re-check
Re-check before onboarding, before bid submission, before payment and again near expiration. SAM registrations lapse every 365 days if they are not renewed.
