What is a CA number for a motor carrier?
A CA number is a carrier identification number assigned through the California Highway Patrol process for motor carriers subject to California motor-carrier requirements. It is not the same as a USDOT number or Motor Carrier Permit, although DMV generally expects the CA number when a carrier applies for or renews an MCP.
How the CA number fits the California carrier record
California uses the CA number to identify a motor carrier in state safety and permit workflows. DMV’s MCP guidance tells new carriers to obtain a CA number before the permit application.
Keep entity and operating information aligned
Use the exact legal name, trade name, address, ownership, and operating information across the CA number, MCP, USDOT, insurance, vehicle-registration, and tax records. A change in the business can require updates in more than one system.
A CA number does not replace other credentials
Depending on the operation, a carrier may also need an MCP, USDOT registration, operating authority, commercial registration, IRP/IFTA, UCR, 2290, driver programs, and state permits.
What Mann does—and what the agency decides
Mann Registration can help collect facts, prepare filings, organize records, and track follow-up. Mann is an independent private service provider, not California Highway Patrol and California Department of Motor Vehicles, and cannot approve an application, change an agency record without the required process, give legal or tax advice, or guarantee timing or results.
