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:
- Creates a formal government record of the dispute
- Adds to the broker’s public complaint history (visible to carriers and shippers who check SAFER)
- Can trigger FMCSA review if the broker accumulates multiple complaints
- Often prompts brokers to resolve the dispute to keep their record clean
- Establishes a paper trail if you pursue additional remedies
What it doesn’t do:
- Guarantee you get paid — the FMCSA is a regulatory agency, not a collections service
- Resolve the dispute directly — the FMCSA investigates compliance, not individual payment disputes
- Replace TIA arbitration or surety bond claims for direct payment recovery
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:
- Broker’s MC number (from the rate confirmation or SAFER)
- Load number / PRO number
- Date of service
- Invoice amount
- Your invoice copy
- The rate confirmation (especially the detention/accessorial terms)
- Documentation of your evidence (GPS reports, telematics data)
- Record of your submission attempts and any responses from the broker
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:
- MC number
- Company name (as registered with the FMCSA)
- Address (from SAFER or rate confirmation)
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:
- Load number and date
- Services performed (detention, TONU, etc.)
- Amount owed
- Date invoiced
- Date of your follow-up attempts
- Broker’s response (or non-response)
- What you believe the broker violated (refusal to pay legitimate contractual claim under 49 U.S.C. § 13904)
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:
- Your invoice
- The relevant pages of the rate confirmation
- Your GPS evidence (if applicable)
- Any email correspondence with the broker
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:
- Signals seriousness
- Gives the broker one more opportunity to resolve
- Creates a contemporaneous record of your attempt to resolve
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:
- Contact the broker for a response
- Issue an educational letter if the complaint indicates regulatory issues
- Refer the matter for investigation if a pattern of violations is found
- Log the complaint as a public record even if no action is taken
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
| Remedy | Cost | Speed | Direct Payment? | Best For |
|---|---|---|---|---|
| FMCSA Complaint | Free | Days to file | No | Record creation, pressure signal |
| TIA Arbitration | Low filing fee | 60–90 days | Yes (binding) | Active brokers disputing valid claims |
| Surety Bond Claim | Free to file | 60–120 days | Yes | Brokers who clearly won’t pay |
| Legal action | Attorney fees | 6–18 months | Yes (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.
