How to Look Up a USDOT Number

Why you'd look one up

• Before you order decals. Confirm the number and the exact legal name or DBA on file, so what goes on the door matches the record.
• Vetting a carrier or subcontractor. See if they're active, authorized, and what their inspection history looks like.
• Checking your own record. Addresses, truck counts, and contact info go stale. Inspectors and brokers see what's on SAFER, not what's in your head.
• Finding a lost number. If you can't find your paperwork, you can search by company name.

Step by step: the SAFER Company Snapshot

1. Go to safer.fmcsa.dot.gov (the official FMCSA site; it's free and needs no login).
2. Choose Company Snapshot.
3. Pick your search type: USDOT Number, MC/MX Number, or Name.
4. Enter the number (digits only, no "USDOT" prefix) or part of the company name, then search.
5. For name searches you'll get a list. Match the city and state to find the right company, since many carriers share similar names.

Be wary of third-party "DOT lookup" sites. Some are fine, but many are lead-generation pages for filing services. The government record is the one that counts.

What the snapshot shows (and what it means)

• Entity type: carrier, broker, shipper, and so on.
• USDOT status: active or inactive, and whether there's an out-of-service order. An inactive number shouldn't be on a working truck.
• Legal name and DBA: the names you're registered under. The name on your trucks should be one of these.
• Physical address, phone, and mailing address.
• MCS-150 form date and mileage: when the registration was last updated.
• Operating authority status: whether the carrier holds for-hire authority (the MC number side). There's a link to the full licensing and insurance record.
• Power units and drivers: the self-reported fleet size.
• Operation classification and cargo carried: for example authorized for-hire, private property, interstate or intrastate.
• Inspections and crashes: roughly the last 24 months, with out-of-service rates compared to the national average.
• Safety rating: most carriers show "none." That's normal and doesn't mean anything is wrong.

Checking someone else's carrier

If you're hiring a trucking company or subcontracting a haul, three quick checks catch most problems: the USDOT status is active, the operating authority is active if they're hauling for hire, and the name and address match the paperwork they sent you. A company with a brand-new number and zero inspections isn't necessarily a red flag, since every carrier starts there. A name mismatch or inactive status is worth a phone call before you load anything.

Your record is wrong. Now what?

FMCSA requires carriers to update their registration (the MCS-150) every two years, and also when key details change, such as your name, address, or operation type. Updates are filed through FMCSA's online registration system. If you've moved, renamed the business, or added trucks, fix the record first and letter the trucks second, so the doors match what an officer pulls up at roadside. Renaming? Get the new name on the record before you print. A mismatch between the door and the registration is one of the common marking mistakes that fail inspections.

"No records found"? Common reasons

• Typo or extra characters. Search digits only.
• Brand-new number. New registrations can take time to show up in every FMCSA system.
• Wrong name. Try the legal name instead of the brand name, or search a shorter piece of it.
• It's a state number, not a USDOT number. Some states issue their own carrier numbers (California's CA number, for one). Those live in state systems, not SAFER. See intrastate USDOT rules.

Got the number? Put it on the truck

Once you've confirmed the number and the name, the markings are simple: the name on the record and "USDOT" plus the number on both sides of the power unit, in sharp contrast and readable from 50 feet in daylight. Our USDOT number decals are cut to that spec, and MC number decals are available if you run for hire. Just got your number? Walk through the new authority checklist next.
