Frequently Asked Questions
Do I need an MC number if I only run in Texas?
No, Texas-only for-hire carriers register with TxDMV instead; an MC is only for interstate for-hire.
How much does an MC number cost?
FMCSA filing fee is $300; USDOT registration is free; BOC-3 and UCR are extra.
Does a private carrier need an MC number?
No; private interstate carriers at 10,001 lbs or more need a USDOT Number only.
How long does MC authority take to become active?
typically about 20–25 days once insurance (BMC-91) and BOC-3 are on file.
