What does this checker check?

It reviews the details you plan to submit for SAM.gov entity validation and flags common problems: an address that looks like a P.O. box or mailbox service, a recurring document that may be too old, and document types that SAM does not accept. It also reminds you that your legal name and address must match your documents exactly.

Does passing this checker guarantee SAM.gov accepts my entity?

No. This is a guide, not a guarantee. It catches frequent mistakes, but the validation provider makes the final decision based on official records. Use it to reduce avoidable rejections, not as a substitute for SAM.gov.

SAM.gov Entity Validation Checker

Check your business name, address, and supporting document against the common reasons SAM.gov entity validation gets rejected, before you submit.

The validation checklist below runs in your browser. The optional live-status lookup sends the UEI or CAGE code you enter to FedFinder's API to check SAM.gov registration data. Do not enter sensitive information. This is a guide, not a guarantee.

Check SAM.gov Expiration & Registration Status

Enter your 12-character Unique Entity Identifier (UEI) or 5-character CAGE code to search FedFinder's stored SAM.gov entity data for registration status, expiration dates, and set-aside representations. This is a refreshed snapshot; verify current registration directly at SAM.gov.
