How to Check DOT Number Status and Operating Authority

To check a DOT number’s status, go to the FMCSA’s free SAFER system, open Company Snapshot, and search by USDOT number, MC/MX/FF number, or company name. The snapshot returns a one-page summary whose “Operating Status” line tells you whether the carrier is currently allowed to operate.¹ The lookup is public, takes under a minute, and works the same whether you’re a shipper vetting a carrier, a driver researching an employer, or an owner checking your own standing.

Running the Search on SAFER

SAFER stands for Safety and Fitness Electronic Records. From the SAFER homepage, choose the Company Snapshot search. You can enter one of three identifiers:

USDOT number. The fastest and most precise search, since every registered carrier has exactly one.
MC, MX, or FF number. Useful when all you have is the carrier’s operating authority number.
Company name. Works when you have neither number, but common names may return multiple hits.

Submit the search and SAFER returns the Company Snapshot: legal name, physical address, USDOT and MC numbers, fleet size, cargo types carried, inspection and crash history, safety rating if one exists, and current operating status.²

Reading the Operating Status Line

The Operating Status field near the top of the snapshot is the single line you need to read first. It answers the yes-or-no question of whether the carrier can legally move freight or passengers right now. The values you’ll see:²

ACTIVE. The USDOT number is active and in good standing.
AUTHORIZED FOR (Passenger, Property, or HHG). The carrier holds active operating authority for the type of transportation listed.
NOT AUTHORIZED. The USDOT number is active, but the carrier has no operating authority on file. This is normal for private carriers hauling their own goods and for intrastate-only operations, neither of which need operating authority in the first place. For a for-hire interstate carrier, it’s a problem.
INACTIVE. The USDOT number has been deactivated. This almost always means the carrier missed its biennial MCS-150 update.
OUT-OF-SERVICE. The carrier is under an out-of-service order and cannot operate at all. This is the most serious status and typically follows significant safety failures or unresolved enforcement actions.

If you’re tendering a load, the carrier should show either ACTIVE with the appropriate AUTHORIZED FOR line, or an ACTIVE USDOT plus a valid reason it doesn’t need authority. Anything else warrants a phone call before you hand over freight.

USDOT Number and Operating Authority Are Tracked Separately

The snapshot shows two different registrations, and confusing them is the most common misreading. The USDOT number is a safety-tracking identifier the FMCSA uses to record inspections, audits, and crash investigations against your company.³ Operating authority, marked by an MC, MX, or FF number, is a separate grant of permission that says what kind of for-hire transportation the carrier is allowed to conduct: general freight, household goods, passengers, brokering, or freight forwarding.⁴

A carrier’s USDOT number can read ACTIVE while its operating authority reads NOT AUTHORIZED, or the other way around. Both lines matter, and both have to be right for the specific job in front of you.

What “Pending” Means

If a newly filed authority shows Pending, the FMCSA is running through a required waiting period. Every new application is published in the FMCSA’s public register, which opens a 10-calendar-day protest window during which anyone can file an objection. Authority won’t go active until that window closes without objection and the applicant has completed remaining requirements, including insurance filings, a BOC-3 process-agent designation, and applicable fees.⁵

Safety Rating on the Snapshot

Not every carrier has a safety rating. The FMCSA only assigns one after conducting an on-site investigation. If a rating is present, it will be one of three values:⁶

Satisfactory. Safety controls are adequate for the carrier’s size and type of operation.
Conditional. Safety controls are inadequate but haven’t yet caused violations of the safety fitness standard.
Unsatisfactory. Safety controls are inadequate and have produced violations. A carrier with a final Unsatisfactory rating is prohibited from operating commercial motor vehicles in interstate commerce.

A blank rating field isn’t necessarily bad news. Many small carriers have simply never been through an on-site investigation. For those carriers, the CSA scores fill the picture.

CSA Scores for a Deeper Look

The FMCSA’s Compliance, Safety, Accountability program runs a Safety Measurement System (SMS) that scores every carrier on an ongoing basis, updated monthly. SMS organizes roadside inspection and crash data into seven categories, called BASICs:

Unsafe Driving (speeding, reckless driving, distracted driving).
Crash Indicator (frequency and severity of crashes).
Hours-of-Service Compliance (driving time, rest periods, logbook records).
Vehicle Maintenance (brakes, lighting, and other mechanical defects).
Controlled Substances and Alcohol (testing violations).
Hazardous Materials Compliance (labeling, containment, handling).
Driver Fitness (licensing, medical certificates, qualifications).

Each BASIC produces a percentile rank against similar-sized operations, and higher percentiles mean worse performance.⁷ Because SMS updates monthly, it reflects recent conduct rather than the date of the last on-site audit. You can view a carrier’s public SMS data through the FMCSA’s CSA website.

Red Flags When Vetting a Carrier

Reading the snapshot as a shipper or broker, a few patterns should stop you:

Operating Status shows INACTIVE, NOT AUTHORIZED (for a for-hire interstate carrier), or OUT-OF-SERVICE.
The AUTHORIZED FOR line doesn’t cover what you’re asking the carrier to haul. Property authority doesn’t authorize household goods; freight authority doesn’t authorize passengers.
A final Unsatisfactory safety rating.
SMS percentiles that sit near the top of the range in a BASIC that matters for your load (Vehicle Maintenance for a long haul, Hazardous Materials Compliance for placarded freight).

The snapshot won’t always display insurance details, but the FMCSA tracks whether required filings are on record, and insurance lapses can revoke authority automatically. If a carrier’s Operating Status recently flipped, that’s worth asking about directly.

If Your Own Number Shows Inactive

Owners who look themselves up and see INACTIVE almost always got there by missing the biennial MCS-150 update. Reactivation is a matter of submitting the correct MCS-150 series form through the FMCSA’s website. The FMCSA warns against using forms downloaded from third-party sites, since outdated versions will be rejected.⁸

Two cautions. Reactivating after a new entrant revocation follows a separate, more involved process with its own instructions on the FMCSA website. And if your operating authority was also revoked, reinstating it takes a separate application on top of reactivating the USDOT number. The two registrations are independent, and fixing one does not fix the other.⁸
