A CA Number, also known as a California Number, is a number issued by the California Highway Patrol (CHP) and is necessary for identifying yourself as a California-based commercial vehicle. It is also a required item for obtaining a California Motor Carrier Permit (MCP). The state of California processes your CA Number order within 1-5 business days. Once you use it to apply for your MCP, the MCP is usually issued in 3-6 weeks. Proof of insurance and the fees must be mailed in with the application to the state of California. The state of California charges $250 for the non-expiring MCP. If you operate vehicles that require a CDL, you will also be required to enroll in the EPN – Employer Pull Notification program as part of the process for the MCP. All California-based carriers with a GVW over 10,000 lbs. are required to have a CA Number and MCP. Out-of-state carriers who operate in California are not required to get a CA Number or MCP.
