How to File an FMCSA Complaint Against a Freight Broker (2026 Guide)

To file an FMCSA complaint against a freight broker, go to the National Consumer Complaint Database at nccdb.fmcsa.dot.gov, select “Household Goods and Freight Broker” as the complaint type, and complete the form with the broker’s MC number, load details, and the nature of the dispute. Filing is free, takes 20–30 minutes, and creates an official government record that affects the broker’s complaint history and can prompt action.


What an FMCSA Complaint Does (and Doesn’t Do)

What it does:

What it doesn’t do:

An FMCSA complaint works best as part of a multi-pronged approach: file the complaint, pursue TIA arbitration for the actual payment, and notify the broker that you’re doing both.


Before You File: What to Have Ready

Gather these before starting the complaint:

A complaint with documentation is more credible and more likely to prompt investigation than a bare complaint with no supporting details.


Step-by-Step: Filing the Complaint

Step 1: Go to the FMCSA NCCDB

Navigate to: nccdb.fmcsa.dot.gov

This is the FMCSA’s National Consumer Complaint Database. It’s the official portal for filing complaints against motor carriers, brokers, and freight forwarders.

Step 2: Select the Complaint Type

Select “Broker” or “Household Goods and Freight Broker” as the entity type. Don’t select “Motor Carrier” — that’s for complaints against trucking companies, not brokers.

Step 3: Enter the Broker’s Information

Enter the broker’s:

Verify the MC number matches the entity on your rate confirmation before proceeding.

Step 4: Describe the Complaint

In the complaint narrative, include:

Be specific and factual:

Keep it professional. FMCSA reviewers respond better to factual, documented complaints than to emotional narratives. Stick to dates, amounts, and broker actions.

Step 5: Attach Documentation

Upload supporting documentation:

Step 6: Submit and Record the Complaint Number

After submission, you’ll receive a complaint reference number. Save this. You’ll use it if the FMCSA contacts you for follow-up, and you can reference it in communications with the broker (“I have filed complaint reference number [X] with the FMCSA regarding this matter”).


Notifying the Broker

After filing, send the broker a brief email:

“[Broker Name], this is to inform you that we have filed complaint reference [number] with the FMCSA regarding unpaid detention/TONU invoice [number] for load [number], dated [date]. We remain open to resolving this directly. Please contact our billing department at [email] to discuss. If we do not hear from you within 10 business days, we will proceed with TIA arbitration.”

This email:

Most brokers who receive this email resolve the dispute rather than allow the FMCSA complaint to stand.


After Filing: What Happens Next

The FMCSA will review your complaint and may:

Resolution timelines vary. The FMCSA is not primarily a collections agency, so don’t expect them to recover your payment directly. The complaint’s primary value is as a formal record and escalation signal.


FMCSA Complaint vs. Other Remedies: When to Use Each

RemedyCostSpeedDirect Payment?Best For
FMCSA ComplaintFreeDays to fileNoRecord creation, pressure signal
TIA ArbitrationLow filing fee60–90 daysYes (binding)Active brokers disputing valid claims
Surety Bond ClaimFree to file60–120 daysYesBrokers who clearly won’t pay
Legal actionAttorney fees6–18 monthsYes (if you win)Large amounts, clear breach of contract

For most detention and accessorial disputes, the optimal approach is: file FMCSA complaint + TIA arbitration simultaneously, notify broker, and wait 10 days for direct resolution before the arbitration hearing proceeds.
