If you've ever looked at the door of a commercial tow rig and noticed a row of numbers on the placard, you might have wondered what they mean. Those aren't random — they're federal and state operating credentials, and they tell you whether the person hauling your RV is legally authorized to do it.
Here's what each one means and why it matters to you as the owner.
TxDMV
Required for Any For-Hire Transport Within Texas
The Texas Department of Motor Vehicles (TxDMV) issues operating authority to for-hire motor carriers operating within the state. If someone is being paid to tow your RV from one point to another within Texas — even a short move across town — they are required by state law to hold an active TxDMV operating number.
This isn't a technicality. The requirement exists to ensure that carriers hauling property for compensation maintain proper insurance, meet safety standards, and are accountable to Texas regulators.
What are the risks to you if your transporter doesn't have one?
- Their insurance may not be valid for commercial hauling. If there's an accident and they aren't properly licensed, their insurer can deny the claim — leaving you to cover damage out of pocket.
- You have limited legal recourse. An unlicensed operator isn't subject to the same regulatory oversight, making disputes much harder to resolve.
- You may unknowingly be party to an unlawful commercial transaction, which can complicate your own insurance claim.
You can verify a carrier's Texas authority through the TxDMV Motor Carrier database at txdmv.gov.
USDOT
The Federal Identifier
Every commercial motor carrier operating in interstate commerce is required to register with the Federal Motor Carrier Safety Administration (FMCSA) and receive a USDOT number. This number is the carrier's federal identifier — it's how the government tracks safety records, inspections, crashes, and compliance history.
The USDOT number alone doesn't grant operating authority. Think of it as the carrier's federal ID number — it has to exist before anything else is issued. You can look up any USDOT number in FMCSA's public SAFER database (more on that below).
MC Number
Authorization to Haul for Hire Across State Lines
The MC number (Motor Carrier number) is issued by the FMCSA and represents active interstate operating authority. This is the credential that legally authorizes a carrier to transport property for compensation across state lines.
If you're hiring someone to move your RV from Texas to Colorado, Florida, or anywhere outside the state, your transporter must hold an active MC number with "authorized" status. If they don't:
- They are operating illegally under federal law.
- Their cargo insurance likely won't cover an interstate move if they weren't authorized to make it.
- In the event of an accident or damage, you could find yourself with no clear path to recovery — the carrier has no federal standing, and their insurer may deny the claim entirely.
- If a DOT inspection occurs during transport, the rig can be placed out of service on the spot, leaving your RV stranded on the side of the road.
This is not a gray area. Interstate for-hire transport without MC authority is a federal violation — and while the consequences land on the carrier, the disruption and financial risk land squarely on you.
How to Check: SAFER
SAFER stands for Safety and Fitness Electronic Records — it's the FMCSA's free public database where anyone can look up a carrier's federal credentials, safety rating, insurance status, and inspection history.
Go to: safer.fmcsa.dot.gov/CompanySnapshot.aspx
Enter the USDOT or MC number and look for:
- Operating Status: Should say Authorized. If it says Not Authorized or Revoked, stop there.
- Operation Classification: Look for Authorized For Hire — this confirms they're legally permitted to haul your property for compensation.
- BIPD Insurance on File: This is cargo and liability insurance. It should show active coverage on file with the FMCSA.
- Out of Service %: Compare against the national average shown on the same page. Significantly above average is a red flag.
The whole lookup takes about 60 seconds and is completely free. Any legitimate transporter will hand you their USDOT number without hesitation.
