What Are DOT and MC Numbers?
If you’re starting a trucking or transportation business in the U.S., you’ll need to register for a USDOT Number and, in many cases, an MC (Motor Carrier) Number.
- DOT Number: Required by the FMCSA to track your safety record and compliance.
- MC Number: Required for carriers who transport regulated commodities or operate as for-hire carriers across state lines.
Who Needs a DOT and MC Number?
You need a DOT and/or MC number if you:
- Transport goods across state lines (interstate)
- Operate commercial vehicles over 10,000 lbs
- Carry hazardous materials
- Get paid to transport goods (for-hire motor carrier)
- Plan to broker or forward freight
Why These Numbers Matter
Your DOT and MC numbers are the foundation of your legal trucking business. Without them, you can’t operate commercially or register for essential filings like UCR, IFTA, or IRP.
Operating without them could lead to:
- Fines from the FMCSA
- Vehicle detainment or roadside shutdowns
- Loss of contracts or insurance coverage

Common Questions
- How long does it take to get a DOT and MC number?
- DOT numbers are issued instantly. MC numbers take 21+ days to become active after insurance and BOC-3 are filed.
- Can I operate while waiting for MC authority?
- No. You must wait until the MC number is active before operating interstate for-hire.
- Do I need both numbers?
- If you’re a for-hire carrier crossing state lines, yes. Private carriers may only need a DOT number.
