How to verify OXYGEN SERVICE CO INC
- Verify USDOT and MC numbers match the carrier's documents. Compare the USDOT number and MC docket on this page to the numbers on the carrier's invoice, rate confirmation, or load-board listing. A mismatch between the carrier's claimed numbers and the registered legal name is the single most common red flag.
- Check active operating authority and insurance status. Confirm the Authority Records show at least one ACTIVE docket for the type of operation you're booking, and that the Active Insurance card lists a current BIPD/Primary policy. A revoked authority or uninsured carrier cannot legally operate.
- Review safety rating and SMS BASIC scores. Check the carrier's FMCSA safety rating (if any) and the SMS BASIC table. A high percentile in any BASIC category — especially Unsafe Driving, HOS, or Vehicle Maintenance — is worth investigating before tendering a load.
- Examine inspection and crash history. Open the Inspection History and Crash History subpages for the full record. Look for patterns: repeat OOS findings on the same unit, multiple crashes in a short window, or violations clustered in one BASIC category.
- Cross-reference real-time data with FMCSA SAFER. For the most current snapshot — within 24 hours of any insurer filing or authority change — click through to the FMCSA SAFER lookup. TruckCodex mirrors SAFER and L&I daily; SAFER itself reflects filings within 24 hours.

About FMCSA carrier records
Every commercial motor carrier operating in the United States is required to register with the Federal Motor Carrier Safety Administration (FMCSA) and obtain a USDOT number. The USDOT number is a permanent, unique identifier — once assigned, it stays with the carrier for life and is never reissued to another company. Carriers must update their registration every two years on Form MCS-150 to keep their address, fleet size, and operating data current.
Carrier safety data lives in FMCSA's Motor Carrier Management Information System (MCMIS): roadside inspections, crashes, out-of-service findings, and the seven Behavior Analysis and Safety Improvement Categories (BASICs) that make up the SMS scoring methodology. For-hire carriers must also hold operating authority — an MC, FF, or MX docket number — which is separate from the USDOT number and requires continuous insurance and BOC-3 process-agent filings to remain active.
TruckCodex mirrors FMCSA's public SAFER and L&I systems on a daily refresh cycle. Every record on this page reflects what FMCSA has on file. We do not edit or modify carrier data — for real-time confirmation immediately before a transaction, click through to the FMCSA SAFER lookup linked in the related records section above. Safety ratings, when present, come from formal compliance reviews; most active carriers have not been reviewed and are correctly listed as unrated.
