California Carrier Registration and Marking
California carriers may need a USDOT number, CA carrier identification number, and Motor Carrier Permit. Caltrans explains display of the CA identifier and the name or trademark requirement for covered vehicles.

Key Compliance Points
- Classify the operation as interstate or intrastate.
- Confirm whether a CA number and Motor Carrier Permit are required.
- Use the exact legal name or permitted trade name connected to the carrier record.
- Display required identifiers on both sides with strong contrast and clear visibility.
- Verify current requirements with the cited agency before operating.
