Verified risk signals. Clear attribution.


01

Risk linked to the right company

Risk is only attached to the right company — confirmed by federal identifiers, not just name matching. Search by UEI, CAGE, USDOT or name; name search is used for discovery only.

02

Federal exclusion & debarment check

Confirmed exclusions are linked by federal identifiers — UEI and CAGE where available. Name-only matches are never treated as confirmed risk.

03

Carrier compliance & OOS status

Carrier risk is linked by USDOT number, not by name. Out-of-service orders are confirmed entity-level risk for the operating carrier.

04

Workplace safety violation history

Inspection and violation signals are tracked at facility level. They are shown as worksite-level signals, not attributed as confirmed company risk.

05

Bulk screening & API access

Business subscribers can query V2 vendor profiles by UEI, CAGE, USDOT or UUID with a REST API key. Verified risk events, identifiers and available source metadata included.

Common questions

KnowVendor reports are designed to document what was checked, what was found, and how records were linked to a vendor. They can support internal vendor screening and procurement documentation. They are not legal advice and should not be treated as a substitute for your organization's compliance process. Paid plans include a printable report (Print / Save as PDF) for that purpose.

KnowVendor focuses on source-backed public data, verified federal identifiers, and explainable entity resolution. Rather than treating every name match as a confirmed signal, KnowVendor separates legal entities, facilities, identifiers, and source records so users can see exactly why a record is linked — and what the confidence level is. See how records are matched →

KnowVendor uses background ingestion and cached source summaries. Update frequency depends on the source and ingestion schedules. Reports include source timestamps where available. Some source datasets may not be refreshed on a fixed daily schedule.

It means KnowVendor did not find verified entity-level risk events in the currently checked and linked sources. It does not mean the vendor has no risk. Some records may be unavailable, not yet ingested, or kept separate because they belong to a facility or worksite rather than the legal entity itself.

KnowVendor prioritizes federal identifiers — UEI, CAGE, and USDOT. Name search is used for discovery, not automatic risk attribution. Facility and worksite records such as OSHA inspections are kept separate unless a reviewed entity link supports attribution. Confidence scores and match evidence are stored with every link. See how records are matched →

KnowVendor currently uses V2 source records from SAM.gov exclusions and entity registrations, FMCSA carrier signals, USAspending Federal Contracting Activity (informational), and facility/worksite-level OSHA data where available. Coverage varies by vendor and source, and not all sources are available for every entity.

Yes. You can get a full vendor report for $19 — one-time, no subscription required. Search for the vendor, open their profile, and purchase the report directly. You get the same full report as Pro subscribers: verified identifiers, risk events, source coverage, and a printable PDF for your records.

No. KnowVendor surfaces public records and risk signals to support your due diligence process. It is not a substitute for legal advice, background check services, or official debarment determinations. Always verify critical findings through primary sources.

Document the vendor check, not just the result

Each paid report shows what was checked, what was found, and how records were linked to the vendor. Use the printable report to keep a timestamped copy for internal procurement review, compliance workflows, or vendor onboarding documentation.

Not legal advice. Not audit certification. Informational documentation from public sources.
