How to Verify a Carrier MC Number: A Step-by-Step Guide for Freight Brokers
Carrier identity fraud — where criminals use stolen or falsified MC numbers to impersonate legitimate carriers — is one of the fastest-growing forms of freight fraud. The FMCSA estimates thousands of carriers are targeted for MC number theft each year. A thorough MC number verification process is your first line of defense. Here is how to do it correctly.
Step 1: Verify the MC Number in FMCSA SAFER
The FMCSA SAFER (Safety and Fitness Electronic Records) database is the authoritative source for carrier verification. Always start here.
Go to safer.fmcsa.dot.gov and search by MC number or DOT number. Verify:
- Authority status: Should show “Active” for interstate for-hire carriers. “Revoked” or “Inactive” means the carrier cannot legally haul loads.
- Legal name and DBA: The name on the MC record must match what the carrier tells you.
- Registered address: Cross-check with where the carrier claims to be located.
- Phone number: This is critical — more on this below.
- Insurance status: Verify both liability and cargo insurance are active and meet your minimum requirements.
- Safety rating: Should be “Satisfactory” or “None” (unrated). “Conditional” or “Unsatisfactory” ratings are red flags.
Step 2: Call the FMCSA-Registered Phone Number
This is the single most important step that most brokers skip.
After pulling the carrier’s SAFER record, call the phone number listed in SAFER — not the number the carrier gave you. Do not use any number from a call-back request, email, or load board message. Call the SAFER-registered number directly and ask:
- “Do you have a driver available for a load from [origin] to [destination] on [date]?”
- Confirm the driver’s name, truck number, and trailer number match what was confirmed
- Ask for the driver’s cell number and verify it matches what your dispatcher was given
Step 3: Verify Insurance Directly with the Insurer
Request a Certificate of Insurance (COI), but do not accept one emailed directly from the carrier without verification. Certificates can be forged.
Instead:
- Get the carrier’s insurance company name from SAFER
- Call the insurance company directly (find the number independently, not from the carrier)
- Confirm the policy is active and the named insured matches the carrier you’re booking
Minimum insurance levels to require from carriers:
- Auto liability: $750,000 minimum (FMCSA requirement for general freight); $1M+ recommended
- Cargo insurance: $100,000 minimum; higher for high-value freight
Step 4: Cross-Reference with Third-Party Carrier Monitoring Tools
SAFER alone is not enough for carriers you’re booking for the first time. Use additional verification layers:
- RMIS (Carrier411): Tracks carrier safety scores, authority changes, and insurance changes in real time
- Highway: Identity verification and ongoing monitoring for active carrier relationships
- MyCarrierPackets: Carrier onboarding with document verification
- Carrier Assure: Predictive safety scoring based on driver and carrier behavior
These tools monitor carriers continuously — they can alert you when a carrier’s authority is revoked, their insurance lapses, or their safety score drops after you’ve already booked them.
Step 5: Verify the Physical Carrier at Pickup
All pre-dispatch verification can be defeated if you can’t confirm the correct carrier actually shows up at your shipper’s dock.
Pickup verification requires:
- Matching the truck and trailer numbers against the dispatch confirmation
- Photographing the driver’s CDL, the truck, and trailer at pickup
- GPS-confirming the carrier is at the authorized pickup location before releasing the load
- Using a digital BOL with a GPS-locked QR code that can only be scanned from the authorized location
Red Flags That Override a Valid MC Number
Even if the MC number checks out in SAFER, these behaviors indicate fraud:
- The carrier contacts you via load board about a load you posted — but you never posted that load (your load was double brokered)
- The carrier’s contact email uses a free domain (gmail, yahoo, hotmail) with a company name that does not match SAFER
- The carrier asks for advance payment before the load is delivered
- The carrier can’t provide specific equipment information (year, make, plate)
- The carrier uses a VOIP phone number that doesn’t match the SAFER-registered number
- The carrier pressures you to complete booking quickly without completing verification
MC Number Verification Checklist
Before dispatching any new carrier: ☐ SAFER authority status is Active ☐ Carrier name and address match what they told you ☐ Called the SAFER-registered phone number ☐ Insurance verified directly with insurer ☐ Third-party monitoring tool check completed ☐ Truck and trailer numbers confirmed in dispatch confirmation ☐ GPS pickup verification enabled at shipper location
Close the Pickup Verification Gap
MC number verification protects you before dispatch. TrackBOL’s GPS-locked QR code BOL verification protects you at the dock — confirming the right carrier is at the right location when they pick up your load.
Frequently Asked Questions
Use the FMCSA SAFER database at safer.fmcsa.dot.gov. Search by MC or DOT number. Verify the carrier’s name, address, phone number, authority status, and insurance. Then call the SAFER-registered phone number to confirm the person calling you is actually affiliated with that carrier.
Yes. MC number theft is common. Even if the MC number shows as active in SAFER, the person using it may be impersonating the real carrier. Always call the SAFER-registered phone number to verify you’re talking to the actual carrier.
A DOT number identifies a carrier for safety oversight. An MC number is required for interstate for-hire carriers. Both are issued by FMCSA. Interstate for-hire carriers need both. Private carriers typically only have a DOT number.
Check insurance directly through FMCSA SAFER, which shows current insurance filings. For new carriers, call the insurer directly to confirm the policy is active. Do not rely solely on a COI provided by the carrier — certificates can be forged.
