Free FMCSA Carrier Lookup — Instant US Carrier Verification
CarrierCheck is a free tool used by freight brokers, shippers, dispatchers, and carriers across the United States to instantly verify any US motor carrier using official FMCSA data. Enter a DOT number, MC number, or company name to get a complete carrier profile in seconds — no account or subscription required.
How CarrierCheck Works
1. Enter a DOT or MC Number
Type any USDOT number, MC docket number, or company name into the search box above. CarrierCheck finds the carrier in the FMCSA database instantly.
2. Get the Full FMCSA Record
See the carrier's authority status, insurance on file, safety rating, fleet size, driver count, contact information, and operating history — all in one view.
3. Check for Red Flags
Spot inactive authority, pending insurance cancellations, authority revocations, or carriers with less than 6 months of operating history before booking a load.
4. Bulk Search Multiple Carriers
Need to verify dozens of carriers at once? Use our Bulk Search tool to look up multiple DOT or MC numbers simultaneously.
What You Can Verify
Operating Authority Status
See if a carrier's Common, Contract, or Broker authority is Active, Inactive, or pending revocation. Never book with a carrier whose authority is not active.
Insurance on File
View BI&PD and cargo insurance coverage amounts, policy numbers, insurer name, and any pending cancellation dates that signal financial risk.
FMCSA Safety Rating
Check whether a carrier holds a Satisfactory, Conditional, or Unsatisfactory FMCSA safety rating. An Unsatisfactory rating is an immediate disqualifier.
Fleet Size & Driver Count
Verify total power units, owned vs leased equipment, total drivers, and CDL drivers. Compare against what a carrier tells you directly.
Contact Information
View physical address, mailing address, phone, email, and company officers on file with FMCSA — and compare against what the carrier provided you.
Authority Age & History
See exactly how long a carrier has held active authority. Carriers under 6 months are higher risk. CarrierCheck color-codes this red, orange, or green for quick reference.
Who Uses CarrierCheck
Freight brokers use CarrierCheck to vet new carriers before onboarding and verify insurance before booking every load. Shippers use it to confirm carriers are authorized and insured before tendering freight. Dispatchers use it to quickly pull up carrier profiles when setting up new carrier relationships. Carriers use it to check their own FMCSA record and make sure their information is current and accurate.
Why Carrier Verification Matters
Booking freight with an unverified carrier carries serious risk. A carrier's operating authority can be revoked at any time. Insurance policies can lapse without notice. Fraudulent carriers use real USDOT numbers but fake contact information to redirect freight deliveries. Double brokering — where a carrier re-brokers your load without authorization — is a growing problem that costs brokers and shippers millions of dollars each year.
A 30-second carrier check on CarrierCheck can prevent these problems entirely. The data comes directly from FMCSA's public database, synced daily, giving you the same information FMCSA uses for enforcement — presented in a fast, readable format.
Frequently Asked Questions
Is CarrierCheck free to use?
Yes, completely free. No account, no sign-up, no subscription. You can search any number of carriers at no cost. CarrierCheck is a free service provided by King Dispatch LLC.
Where does the carrier data come from?
All data is sourced from the Federal Motor Carrier Safety Administration (FMCSA) public database and synced daily. It's the same data that powers FMCSA's SAFER system, presented in a faster and more readable format.
What is the difference between a DOT number and MC number?
A USDOT number identifies a carrier for safety and compliance purposes. An MC number is their operating authority — required to transport goods for hire across state lines. If a carrier is hauling your freight across state lines, they need both. Both are searchable on CarrierCheck.
How current is the carrier data?
CarrierCheck syncs with the FMCSA database daily, so data is typically no more than 24 hours old. For critical decisions, you can also cross-reference directly with FMCSA's SAFER system at safer.fmcsa.dot.gov.
Can I search by company name?
Yes. In addition to DOT and MC numbers, you can search by carrier company name. CarrierCheck will return matching carriers from the FMCSA database so you can identify the right one.
What does "pending insurance cancellation" mean?
A pending insurance cancellation means the carrier's insurer has filed a notice with FMCSA that the policy will be cancelled on a specific date. This is a serious red flag — do not book loads with that carrier until the insurance issue is resolved and the cancellation notice is removed.
What is "authority in revocation"?
An authority revocation pending means FMCSA has initiated the process of revoking a carrier's operating authority. The authority may still technically be active, but a revocation pending is a serious warning sign. Avoid booking loads with carriers showing pending revocations.
