DOT, USDOT & MC Number Lookup
Verify any trucking company before you book. Search the FMCSA SAFER database by USDOT or MC number to confirm the carrier is real, active, allowed to operate, and not out of service.
How to use: Enter a USDOT or MC docket number to pull live FMCSA data — legal name, DBA, address, fleet size, operating authority, safety rating, and out-of-service status.

What is a USDOT number?
A USDOT number is a unique identifier the Federal Motor Carrier Safety Administration assigns to commercial vehicles operating in interstate commerce. It is the federal record-of-truth for who a carrier is, where they are based, and whether they are legally allowed to haul freight.
Every for-hire carrier, broker, and freight forwarder operating across state lines must register and keep a USDOT number current. The number is the key the FMCSA uses to track safety inspections, accident records, insurance filings, and operating authority.
MC number lookup: verify operating authority
The search box above also runs an MC number lookup. Choose MC number, enter the docket number, and the tool pulls the FMCSA record behind that authority: legal name, DBA, operating authority type (carrier, broker, or freight forwarder), and whether the authority is active or out of service.
Run an MC lookup when a rate confirmation, insurance certificate, or load board posting gives you a docket number and you need to confirm the operating authority is real and active. If you only have the USDOT number, search that instead: the FMCSA record links both identifiers. New to the terminology? See what an MC number is.
FMCSA DOT lookup: the same SAFER data, no CAPTCHA
This tool is a free FMCSA USDOT number lookup. SAFER (the FMCSA's Safety and Fitness Electronic Records system) is the federal registration database behind every carrier search, and the results above come from the same registration data: legal name, DBA, physical address, fleet size, operating authority, safety rating, and out-of-service status.
Why DOT verification matters
Tendering freight to an unverified carrier is the most common way shippers lose loads to fraud. Brokers and shippers who skip the lookup discover too late that the legal name on the BOL does not match the FMCSA record, the operating authority is inactive, or the carrier is out of service. The freight gets impounded or stolen, and insurance does not cover it.
A 30-second DOT lookup catches every common red flag — fake authority, dormant carriers, identity-spoofed brokers, and out-of-service operators. Verify before you tender. Verify again before you release the load.
Warp pre-vets every carrier in the network
Warp does not put a load on a truck until the carrier passes operating-authority, insurance, safety-rating, and out-of-service checks. Status is re-verified the morning of dispatch. You do not have to run a DOT lookup before every booking — that work is already done.
Use this tool when you are evaluating a carrier you found outside the Warp network, auditing a load board match, or confirming a quote from a broker you have not worked with before.
DOT lookup FAQ
What is a USDOT number?
A USDOT number is a unique identifier issued by the FMCSA to commercial vehicles operating in interstate commerce. Carriers, brokers, and freight forwarders are required to register and maintain a USDOT number to operate legally.
What is the difference between a DOT number and an MC number?
A DOT number identifies a company for safety oversight. An MC docket number is the operating authority that allows a company to transport regulated commodities for hire across state lines. Most for-hire carriers have both. Private carriers typically only have a DOT number.
How do I look up an MC number?
Use the search tool at the top of this page: choose MC number, enter the docket number, and the lookup returns the FMCSA record for that authority, including legal name, authority type and status, and out-of-service flags. If you only have the USDOT number, search that instead; the record links both identifiers.
How do I verify a trucking company before booking?
Look up the carrier by DOT or MC number, confirm the legal name and address match what they gave you, check that the status is active and allowed to operate, verify they are not out of service, and confirm the operating authority covers the freight you need to move.
What does "out of service" mean?
Out of service means the FMCSA has issued an order prohibiting the carrier from operating commercial motor vehicles. Never tender freight to an out-of-service carrier — the load can be impounded and your insurance may not cover the loss.
What is a satisfactory safety rating?
FMCSA safety ratings are Satisfactory, Conditional, or Unsatisfactory. The rating is based on a compliance review of driver, vehicle, hazmat, and accident records. Many carriers are unrated because they have not been audited yet — that is not the same as a poor rating.
How often is the FMCSA SAFER database updated?
FMCSA SAFER pulls from the live carrier registration system and refreshes daily. Recent changes to operating authority, out-of-service status, or insurance can take 24 to 48 hours to reflect.
Can I look up brokers and freight forwarders here?
Yes. Brokers and freight forwarders are also registered with the FMCSA and have DOT and MC numbers. The lookup returns their operating authority type, which tells you whether they are licensed to broker, forward, or carry freight.
Is this the same as the FMCSA SAFER company snapshot?
It searches the same federal registration data that powers the FMCSA SAFER company snapshot: legal name, DBA, address, fleet size, operating authority, safety rating, and out-of-service status. The FMCSA site remains the official system of record for full inspection and crash history; this lookup is the fast way to run the everyday carrier check.
How do I run a free FMCSA USDOT number lookup?
Enter the USDOT number in the search box at the top of this page and the FMCSA record returns instantly: legal name, authority status, fleet size, safety rating, and out-of-service flags. It's free, with no login and no CAPTCHA. If you only have an MC docket number or the company name, search those instead.
Is there a DOT number lookup without a CAPTCHA?
Yes. This lookup searches the same FMCSA SAFER registration data with no CAPTCHA and no login. Type a USDOT number, MC number, or carrier name and results return instantly: legal name, authority status, safety rating, fleet size, and out-of-service flags in one view.
Do I need to verify carriers if I book through Warp?
No. Every carrier in the Warp network is pre-vetted on authority, insurance, safety rating, and out-of-service status. Warp re-verifies status before every dispatch. Use this lookup for carriers found outside the network.
