TxDMV Number vs USDOT Number: Which Texas Carriers Need Both

Reviewed by Austin Park, founder of ICR Filings · Updated November 11, 2026

The short answer
  • A USDOT number is an identifier from FMCSA. TxDMV says it is not operating authority.
  • A TxDMV certificate (formerly the TxDOT number) is authority to operate intrastate in Texas.
  • You get the USDOT number first. TxDMV requires a valid one before you apply.
  • Crossing state lines takes interstate authority (an MC number) from FMCSA. Carriers doing both kinds of work need both kinds of authority.

Texas carriers hear three numbers thrown around: USDOT, MC, and TxDMV (or the old name, TxDOT). They come from different agencies and do different jobs, and having one does not cover the others.

TxDMV certificateTxDMVIntrastate operating authorityCarriers hauling inside Texas that meet TxDMV's thresholds
MC numberFMCSAInterstate operating authorityCarriers crossing state lines for hire

The USDOT number comes first

TxDMV tells new carriers to start with FMCSA and get a USDOT number, and says you must have a valid one before you begin a TxDMV application. It also describes what the number is and is not: a USDOT number is not operating authority, it is basically an identifier. To keep it active you update Form MCS-150 with FMCSA every two years. See how to get a USDOT number.

One detail matters for Texas-only carriers. TxDMV says that if your operations are conducted exclusively within Texas, you should register with USDOT as intrastate, not interstate.

The TxDMV certificate is authority inside Texas

For local moves and intrastate hauling, TxDMV says you need intrastate operating authority: a TxDMV certificate, formerly known as a TxDOT number. You must register as a motor carrier when you:

  • Operate a commercial motor vehicle, or a combination, with a gross weight, registered weight, or gross weight rating over 26,000 pounds.
  • Transport hazardous materials in a quantity that requires placarding.
  • Operate a farm vehicle with a gross weight, registered weight, or gross weight rating of 48,000 pounds or more.
  • Operate a vehicle designed to transport more than 15 passengers, including the driver.
  • Operate a commercial school bus.
  • Transport household goods for compensation, regardless of vehicle weight.

You apply in TxMCCS, your insurer files proof of insurance with TxDMV, and you pay the fees. The cost is in how much a Texas DOT number costs.

The MC number is authority across state lines

If you cross state lines, TxDMV says you need interstate operating authority, an MC number, from FMCSA. Then it answers the question carriers ask most: if you do both kinds of work, you need both kinds of authority, and one does not cover the other. Telling FMCSA you operate interstate also brings yearly UCR registration. For the federal side, see USDOT number vs MC number.

“If you do both kinds of work, you need both kinds of authority. One doesn't cover the other.”
TxDMV: Becoming a Texas motor carrier

Three common cases

  • A dump truck over 26,000 pounds working only in Texas: USDOT number registered as intrastate, plus a TxDMV certificate.
  • A for-hire truck running Texas to Oklahoma only: USDOT number and an MC number. No TxDMV certificate for that interstate work.
  • The same truck doing both: USDOT number, MC number, and a TxDMV certificate.

What TxDMV does not handle

TxDMV does not regulate driver licensing or motor carrier safety audits. In Texas those belong to the Department of Public Safety.

Already have a certificate and cannot log in? TxDMV changed systems in August 2026: see TxMCCS login and claiming your certificate.

Common questions

Is a TxDMV number the same as a USDOT number?

No. The USDOT number is a federal identifier from FMCSA. The TxDMV certificate is Texas intrastate operating authority from the Texas Department of Motor Vehicles.

Is a TxDMV number the same as a Texas DOT number?

Yes, in everyday use. TxDMV says its certificate was formerly known as a TxDOT number.

Do I need a USDOT number if I only haul inside Texas?

Yes. TxDMV says to start with a USDOT number from FMCSA, and that you must have a valid one before applying for a TxDMV certificate. If your operations are only within Texas, register with USDOT as intrastate.

Do I need an MC number too?

Only if you cross state lines. TxDMV says interstate work needs interstate operating authority (an MC number) from FMCSA, and that if you do both kinds of work you need both kinds of authority.

Does a Texas-only carrier pay UCR?

TxDMV says UCR fees apply if you tell FMCSA you are operating interstate. A carrier registered as intrastate only does not register for UCR on that basis.

Who handles CDLs and safety audits in Texas?

The Texas Department of Public Safety. TxDMV says it does not regulate driver licensing or motor carrier safety audits.
