All interstate moving companies are required by federal law to have an active USDOT number issued by the FMCSA, searchable at safer.fmcsa.dot.gov. Intrastate (same-state) movers are regulated by individual states and require state-specific moving licenses. Verifying these numbers is the single most important step to avoid fraud. Here is the complete guide.
What is a USDOT number?
A USDOT number is a unique federal identifier for commercial carriers operating across state lines. It links to safety records, insurance status, and complaint history. Always confirm it's active, not just present.
USDOT vs. MC number: what's the difference?
| Identifier | Purpose | | --- | --- | | USDOT number | Federal registration and safety tracking | | MC (Motor Carrier) number | Operating authority for interstate "for-hire" transport |
Most legitimate interstate household movers hold both. Estimate your move with the moving cost calculator while you verify credentials.
How does state intrastate licensing work?
Moves within a single state are regulated by that state (often a public utilities commission or DOT). Requirements vary widely — some states require bonding and insurance filings, others are lighter. Always check your state's rule.
How do I search the FMCSA database?
- Go to safer.fmcsa.dot.gov.
- Enter the carrier's name or USDOT number.
- Confirm the legal name matches your quote.
- Review the insurance status and complaint history.
This is the verification backbone behind our moving scams guide.
What do the results tell you?
Active operating authority, insurance on file, fleet size, and safety/complaint records. A flood of complaints or "out of service" status is a major warning.
What are the red flags in FMCSA records?
- No USDOT number or an inactive one
- A name mismatch between the record and your quote
- Insurance lapses
- A pattern of unresolved complaints
