To run a California Motor Carrier Permit search, go to the DMV’s Active Motor Carriers page under Vehicle Industry Services, then Motor Carrier Services, and search by the carrier’s CA number or business name. The list is public, free, and refreshed every business day, so the status you see reflects where the carrier stood as of the last update.1California Department of Motor Vehicles. Active Motor Carriers
The search returns the permit’s current status, which is the point of the tool: it tells you whether the carrier is authorized to haul property on California highways right now. Selecting a CA number from the results also plots the carrier’s location on a map.
What to Have Ready Before You Search
The most reliable search key is the CA number. Every motor carrier must obtain one under Vehicle Code 34507.5, and it must be displayed on both sides of each vehicle, so you can often read it straight off the truck.2Caltrans. CA Number
If you don’t have a CA number, you can search by legal name or doing-business-as name. The database matches against official business registrations, so a comma, an “Inc.,” or a misspelling can be the difference between a hit and an empty result. If the company has changed names, checking the name history with the California Secretary of State first will save you time.
A U.S. DOT number is a federal identifier and won’t necessarily pull a match in the California system. If that’s all you have, look the carrier up on the federal FMCSA SAFER database first to find the legal name and CA number, then run those through the DMV.
What the Results Do and Don’t Tell You
The Active Motor Carriers list is a status page. It confirms whether a permit is active, and it identifies the carrier and where it is based. If the carrier isn’t on the list, either the permit is not active or you’re searching under the wrong name or number.
The list does not show a carrier’s full compliance history, its insurance policy details, its safety inspection record, or the reason behind a past suspension. For any of that, you’ll need to go past the public list. Some records are available on request without a formal process; others require a submission through the DMV’s Public Records Act portal.3California Department of Motor Vehicles.

Why a Carrier Might Not Show as Active
A permit that isn’t active is usually inactive for one of a few reasons, and knowing them helps you interpret what the search is telling you.
Insurance or Workers’ Compensation Lapse
The DMV suspends a permit on the date liability insurance coverage ends when it receives a cancellation notice from the insurer. Vehicle Code 34630 requires proof of insurance on file before a permit is issued, and it stays a condition of keeping one.4California Legislative Information. California Code Vehicle Code 34630 A workers’ compensation lapse triggers the same result under Vehicle Code 34640.5California Legislative Information. California Code Vehicle Code 34640
Insurer paperwork errors do happen. When a carrier switches insurers, the old company can file a cancellation before the new policy is recorded, and the permit goes inactive even though coverage never actually lapsed. If you’re looking up your own permit and see this, it’s fixable.
Safety Sanctions Under the BIT Program
The California Highway Patrol inspects terminals and vehicles under the Basic Inspection of Terminals program, and Vehicle Code 34670 sets an escalating suspension schedule when a carrier fails.6California Legislative Information. California Code Vehicle Code 34670 A first sanction is a 30-day suspension; a second within 36 months is 60 days; a third or more within 36 months is a 90-day suspension plus a $1,500 fine.
Unpaid Renewal or Missed Renewal Window
An intrastate MCP is valid for 12 months, running from the first day of the month you apply through the last day of the twelfth month, and it must be renewed each year with fees paid. Interstate motor carriers get a non-expiring MCP and pay no renewal fees.7California Department of Motor Vehicles. Motor Carrier Permits The DMV asks that you allow 30 days after submitting a renewal for the new permit to arrive by mail, so a permit briefly showing inactive around a renewal date can be a processing gap rather than a compliance problem.8California Department of Motor Vehicles. Motor Carrier Permit FAQs
Who You Won’t Find in This Database
The MCP covers carriers of property, so a search here won’t help you verify certain operators. Passenger carriers aren’t subject to the MCP, and household movers operate under a separate permit issued by the Bureau of Household Goods and Services.9California Legislative Information. California Code Vehicle Code 34622
Several vehicle categories also fall outside the MCP requirement under Vehicle Code 34601, so their operators may lawfully appear nowhere on the list. These include pickup trucks meeting the conditions in Vehicle Code 471, two-axle daily rental trucks under 26,001 pounds GVWR used noncommercially, personal-use motortrucks and two-axle truck tractors under 26,001 pounds GVWR that are never used commercially, and vehicles carrying hazardous materials that don’t require placards or specific licensing when not used commercially.10California Legislative Information. California Code Vehicle Code 34601 Absence from the database, by itself, is not proof that someone is operating illegally.
For everything the MCP does cover, the rule is straightforward. Any person or business operating a commercial motor vehicle to transport property on a public highway must hold a valid MCP before starting operations, per Vehicle Code 34620.11California Legislative Information. California Code Vehicle Code 34620 That includes vehicles rated 10,001 pounds GVWR or more and any vehicle transporting placarded hazardous materials regardless of weight. Both for-hire and private carriers fall under the requirement, and independent owner-operators need their own MCP unless they run under another carrier’s authority.7California Department of Motor Vehicles.

Checking Your Own Permit Before a Shipper Does
Shippers in regulated industries routinely run this same search before booking loads, and load boards that require proof of authority will exclude carriers whose permits show inactive. Running the search on yourself, on the same page a broker or shipper will use, tells you what they’ll see. If the status is wrong or a renewal is close, you have a chance to fix it before it costs you a contract.
If you’re verifying a carrier before hiring them, one lookup gives you a definitive answer on their authority to run in California today. Anything beyond that basic status, including insurance filings and inspection history, is a records request rather than a database search.
