A CA number refers to a unique identifier assigned to a commercial vehicle by the CHP when it is registered with the Motor Carrier Permit (MCP) program.
The MCP program is a regulatory program administered by the CHP that requires certain commercial vehicles operating in California to obtain a permit and comply with various safety regulations. As part of the MCP program, the CHP assigns each registered commercial vehicle a CA number, which is displayed on the vehicle in a specific format.
The CA number is used by the CHP and other law enforcement agencies to identify commercial vehicles and enforce safety regulations. It can also be used by the public to report safety concerns related to commercial vehicles to the CHP.
If you are a commercial vehicle operator in California, you will need to obtain an MCP and a CA number in order to legally operate your vehicle in the state. The process for obtaining an MCP and CA number involves completing an application, providing required documentation, and meeting certain safety and insurance requirements.
What’s the difference?
These are all requested separately, in sequence, but are all interconnected. You cannot get a CA number without a DOT, you cannot get a MCP without a CA.
For the most part, it is required to display your CA number (MCP permit number) on both sides of your truck.
