Differences Between a DOT Number and MC Number

If you're in the market for shipping a car, you may have come across references to DOT and MC numbers. But what do these codes mean? What's the difference between them?

This blog post will explain everything you need to know about DOT and MC numbers, including what they represent and which one you need for your specific shipment. Stay tuned!

What is A DOT number?

A Department of Transportation (DOT) number is a unique identifier assigned to each commercial vehicle. It consists of a combination of numbers and letters.

It must be displayed on the vehicle's door or on a sign on the back of the vehicle.

The DOT number is released and approved by the FMCSA or the Federal Motor Carrier Safety Administration. This is the operating authority regulating all vehicles in the United States.

All commercial vehicles hauling passengers or cargo in interstate commerce must have a DOT number. This includes trucks, buses, trailers, and other types of equipment.

The DOT number must be renewed every year via the official interstate operating authority. Also, it must be kept up to date at all times. If a commercial vehicle changes ownership, the new owner must update the DOT number with the new information.

What is the Department of Transportation number used for?

The DOT number is used for many purposes, including:

• ​Identifying the vehicle
• Recognition by multiple operating authorities
• ​Overseeing the condition and maintenance of the vehicle by private carriers
• Tracing the vehicle's ownership history and accident records

What Are Its Benefits

Here are several benefits to having a DOT number:

• ​It ensures that commercial vehicles are safe and well-maintained by a trucking company.
• ​It reduces the number of accidents involving commercial vehicles.
• ​It makes tracking down the owner of a commercial vehicle in an accident or incident easier.

How do you get it?

A DOT number is assigned by the FMCSA, which oversees all commercial vehicles in the United States.

You'll need to apply to your local FMCSA office to get a DOT number. Keep in mind that there are strict eligibility requirements and guidelines for getting a DOT number. So, it's essential to understand what these are before applying.

If you're ready to apply for a new DOT number or want to update your existing one, contact your local FMCSA office as soon as possible.

With a DOT number in hand, you are assured that your commercial vehicle is up-to-date and compliant.

What is an MC number?

MC is a shortened term for Motor Carrier. All carriers hauling passengers and goods across state lines need an MC number.

It is a statewide operating body and special identification information given by the FMCSA to logistic/moving businesses that engage in interstate commerce or transportation freight over state lines.

To get an MC number from the Department of the carrier, you need to apply online or fill out a form at your local FMCSA office. Then, you must supply detailed information about your company and its for-hire carriers. Hence, preparing these documents in advance is essential.

The system automatically assigns the MC number. But it's not considered valid until an employee at the DOT headquarters has verified it.

Once this step has been completed and approved, you will receive your official MC number certificate within two weeks.

What is the Motor Carrier Number used for?

The MC number is used to track the safety and compliance of carriers hauling people and goods across state lines. It's also used to identify the carrier in an accident or incident.

What Are Its Benefits

Here are several benefits to having an MC number:

• Reduces the chances of being involved in an accident
• Makes it easier to get insurance coverage
• Improves your company's credibility and reputation

How do you get it?

You must first apply and meet specific eligibility requirements to get an MC number. This typically involves providing information about your company and its safety record. It also includes taking a written exam and paying applicable fees.

The specific application process will vary depending on your location. So, consult with your local FMCSA office or carrier safety authority for guidance. With their support and assistance, you can get an MC number in no time.

How are the DOT number and MC Number Different from Each Other?

The FMCSA used DOT and MC numbers to track and oversee commercial vehicles in the United States. But they differ in several key ways.

The DOT number is primarily used for safety and maintenance purposes. In contrast, the MC number serves a broader purpose of tracking carriers across state lines.

Also, obtaining an MC number is typically more involved than getting a DOT number. It involves filling out a detailed application and submitting documents to your local FMCSA office.

Finally, getting an MC number is generally more stringent than those for a DOT number. For example, you may be required to have specific insurance coverage. You may also need to meet certain operational standards to qualify for the MC number.​

While all interstate movers must have and display a DOT number on their commercial carriers, not all movers are required to have an MC number.

Some interstate moving companies require an MC number and a DOT number. For-hire carriers that haul passengers or federally restricted items over state boundaries must also get an interstate operating authority MC number. For-hire carriers who solely transport non-federally regulated goods are typically excluded from obtaining an MC number.

Suppose you're looking to get one of these numbers for your commercial vehicle. First, you should understand all the eligibility requirements and guidelines. This will help you prepare your application in advance and improve your approval chances.

Getting a DOT or MC number can be a relatively straightforward process with the proper knowledge and planning.​

Which One Should You Use?

The DOT number is required for all interstate commercial vehicles. In contrast, the MC number is only required for certain types of interstate commercial vehicles.

If you're not sure which one you need, it's best to contact your local FMCSA office for more information.

You should use the DOT number if:

• You are hauling passengers or goods across state lines.
• You operate a vehicle with a gross vehicle weight rating (GVWR) of 10,001 pounds.
• You are hauling hazardous materials that require placards.

In contrast, you should use the MC number if:

• You are hauling passengers or goods across state lines, and your vehicle has a GVWR of less than 10,001 pounds.
• You are operating a vehicle that requires a Hazardous Materials Transportation Safety Permit.
• You are hauling hazardous materials that don't require placards.
