It's the single source of truth for that carrier's safety, compliance, and operating authority — used by brokers, shippers, insurers, factoring companies, and law enforcement to verify a fleet is legitimate and in good standing.

USDOT lookup — frequently asked
What is a USDOT number?
A USDOT number is a unique identifier issued by the Federal Motor Carrier Safety Administration (FMCSA) to commercial motor carriers that operate in interstate commerce. It's used to track a carrier's safety record, inspections, crashes, audits, and compliance reviews.
How do I look up a USDOT number?
Enter the carrier's USDOT number, MC/MX number, or legal company name above. We send you straight to the official FMCSA SAFER Web snapshot — the same source state troopers and brokers use — so the data is always live and authoritative.
What information will I see?
The official SAFER snapshot shows the carrier's legal name, DBA, address, phone, MCS-150 mileage, power-unit count, driver count, operating status, out-of-service status, safety rating, and roadside inspection / crash history for the last 24 months.
Is USDOT lookup free?
Yes. FMCSA SAFER is a free, public-record system. Rigmatix doesn't add fees, accounts, or paywalls on top of it.
Why would a broker or shipper check my USDOT?
Before tendering a load, brokers verify your operating authority is active, your insurance is on file, your safety rating isn't 'Unsatisfactory', and you aren't flagged out-of-service. A clean USDOT record gets you more loads at better rates.
How do I get a USDOT number?
Apply through the FMCSA Unified Registration System (URS) at fmcsa.dot.gov/registration. Most carriers operating commercial vehicles >10,000 lbs GVWR in interstate commerce are required to have one.
