How to Check a USDOT Number and MC Number: Complete FMCSA Lookup & Verification Guide

If you are hiring a trucking company, checking a freight broker, arranging vehicle transportation, working with a carrier, or simply trying to verify whether a transportation business is properly registered, one of the first things you should do is check its USDOT number and, when applicable, its MC number.

These numbers connect a transportation business to federal registration and regulatory records maintained by the Federal Motor Carrier Safety Administration (FMCSA).

A proper FMCSA lookup can reveal much more than a company name.

Depending on the entity and available records, you may be able to review its:

• USDOT status
• Legal name
• DBA name
• Entity classification
• Operating status
• MC, FF, or MX authority
• Authority status
• Insurance filings
• Broker bond or trust information
• BOC-3 information
• Power units
• Drivers
• Cargo classifications
• Inspection history
• Out-of-service information
• Crash information
• Safety rating
• Regulatory history

However, checking a number is only the beginning.

The important part is understanding what the information actually means.

This guide explains how to perform an FMCSA lookup, how to check both USDOT and MC numbers, how to interpret active and inactive statuses, how to verify a carrier or broker, what to look for in insurance and authority records, and which common mistakes to avoid.

What Is an FMCSA Lookup?

An FMCSA lookup is a search of federal transportation registration or safety information associated with a transportation entity.

FMCSA provides several systems and resources for researching transportation companies. Its safety-record resources include the SAFER System, which provides a Company Snapshot containing information such as company identification, size, cargo, inspection and out-of-service summaries, crash data, and safety rating information when available.

Depending on the search system and information available, a company can be searched using identifiers such as:

• USDOT Number
• MC Number
• FF Number
• MX Number
• Legal Name
• DBA Name
• State

The FMCSA Licensing & Insurance search also allows users to search by USDOT or docket number and, when those numbers are unknown, by legal name, DBA name, and state.

What Is a USDOT Number?

A USDOT number is a federal identification number used by FMCSA to identify regulated transportation entities and associate applicable registration and safety information with them.

For example:

USDOT 1234567

A USDOT number can be associated with information such as:

• Legal business name
• DBA
• Business address
• Operating classification
• Power units
• Drivers
• Cargo classifications
• Safety information
• Inspection data
• Crash information
• Registration history

Not every field applies to every entity.

A broker, for example, should not automatically be interpreted as a motor carrier simply because it has an FMCSA record.

What Is an MC Number?

An MC number generally refers to an FMCSA operating-authority docket number.

FMCSA explains that interstate operating authority is often identified by an MC, FF, or MX number, depending on the type of authority granted. Operating authority determines the type of operation a company is permitted to conduct and the cargo it may transport under that authority.

An MC number therefore answers a different question from a USDOT number.

USDOT

Primarily identifies the transportation entity and connects it to applicable safety and registration information.

MC

Generally identifies applicable interstate operating authority.

A company can have a USDOT number without having the same type of operating authority associated with an MC number.

USDOT Number vs. MC Number

The key point is:

A USDOT number and an MC number should not be treated as interchangeable.

When a company provides both, check both.

How to Check a USDOT Number

The simplest approach is to search the company's USDOT number through an official FMCSA source.

A typical verification process is:

Step 1: Obtain the USDOT Number

Get the number directly from the company, its documents, vehicle markings, website, or another business record.

Be careful when copying the number.

A single incorrect digit can return the wrong company or no record.

Step 2: Search the Official FMCSA Record

Use an official FMCSA search resource to locate the company's record.

You can search using the USDOT number when available.

Step 3: Confirm the Legal Name

Compare the FMCSA legal name with the name provided by the company.

Do not rely solely on a similar-looking DBA or brand name.

Step 4: Check USDOT Status

Review whether the USDOT record is currently active or inactive.

Step 5: Confirm Entity Type

Determine whether the record represents a:

• Motor carrier
• Broker
• Freight forwarder
• Combination or dual-authority entity
• Other applicable registration

Step 6: Review Operating Status

Check the current operating-status information.

Step 7: Review Authority

If the company has MC, FF, or MX authority, review the applicable authority information separately.

Step 8: Review Insurance or Financial Responsibility

For applicable entities, review the insurance, bond, or trust information available through FMCSA.

Step 9: Review Safety Information

For carriers, review available inspections, crashes, out-of-service information, and safety-rating information.

Step 10: Check Dates

Pay attention to dates attached to regulatory information.

A company record can change over time.

How to Check an MC Number

An MC number can be checked through FMCSA's authority and licensing resources.

For example:

MC 123456

When checking an MC number, confirm:

• The docket number
• The legal name
• The entity associated with the authority
• Authority type
• Authority status
• Authority scope
• Grant date
• Authority history
• Applicable insurance or financial responsibility
• BOC-3/process-agent information where applicable

FMCSA's official guidance states that operating authority status can be checked using the Licensing & Insurance system by entering an MC or USDOT number.

How to Check a Company by Name

You do not always need a USDOT or MC number to begin a search.

FMCSA's Licensing & Insurance search allows searches using combinations of:

• Legal Name
• DBA Name
• State

The system notes that name searches generally work from the beginning of the entered legal or DBA name, with a wildcard option available for broader searches. FMCSA recommends using a state when searching by name to narrow results.

Name searches should be treated as an identification step.

If multiple companies have similar names, confirm the correct company using its:

• USDOT number
• Address
• State
• DBA
• MC number
• Other identifying information

What Does "Active" Mean?

An active status indicates that the applicable registration record is currently active.

But active does not mean:

• The company is guaranteed to provide good service
• Every shipment is insured
• Every authority type is active
• The company has no violations
• The company has no complaints
• The company is financially healthy
• The company will perform well on a future shipment

It is a regulatory status, not a customer-service rating.

This distinction is critical when interpreting transportation records.

What Does "Inactive" Mean?

An inactive USDOT status means the registration is not currently active.

The reason for an inactive status should be checked from the underlying regulatory record.

Do not automatically assume that an inactive record means:

• fraud
• theft
• a scam
• permanent closure
• criminal activity

The status should be interpreted using the relevant FMCSA information and dates.

What Does "Authorized" Mean?

Operating-authority information can indicate what types of interstate for-hire operations an entity is authorized to conduct.

FMCSA distinguishes operating-authority statuses such as:

• Authorized For
• Not Authorized
• Out-of-Service

The specific authorized category can identify passenger, property, or household-goods authority where applicable.

Therefore, when you see:

AUTHORIZED FOR PROPERTY

that is different from simply seeing:

USDOT ACTIVE

The two statuses answer different regulatory questions.

What Does "Not Authorized" Mean?

"Not Authorized" generally means the entity does not currently have applicable operating authority or is not authorized to engage in the relevant interstate for-hire operation.

It does not necessarily mean the USDOT registration itself is inactive.

This is an important distinction.

A record can have a USDOT status and an operating-authority status that provide different pieces of information.

Always examine both.

What Does "Out-of-Service" Mean?

An out-of-service status is a serious regulatory status indicating that a carrier is subject to an applicable out-of-service order and is not authorized to operate under that order.

FMCSA specifically distinguishes OUT-OF-SERVICE from ordinary authority statuses.

Do not confuse:

USDOT Inactive

with:

Operating Authority Out-of-Service

They are not necessarily the same thing.

How to Check a Carrier's Insurance

Insurance is one of the most important areas to review when evaluating a transportation company.

FMCSA requires applicable entities with operating authority to maintain required financial responsibility filings.

The exact requirement depends on factors including:

• Entity type
• Type of authority
• Cargo
• Vehicle type
• Operation

FMCSA publishes specific insurance requirements under federal regulations, including requirements for motor carriers, brokers, and freight forwarders.

Depending on the entity, records may include information such as:

• Insurance company
• Policy information
• Coverage amount
• Effective date
• Cancellation date
• Financial responsibility filing
• Bond or trust filing

Do not assume that one insurance requirement applies to every transportation business.

How to Check a Freight Broker

A freight broker should be evaluated differently from a motor carrier.

A broker typically arranges transportation rather than operating the truck performing the shipment.

When checking a broker, look at:

1. Company identity

Confirm:

• Legal name
• DBA
• USDOT number
• Applicable docket number

2. Broker authority

Check the applicable operating authority and current status.

3. Broker financial responsibility

FMCSA's requirements include a $75,000 surety bond or trust fund for applicable property brokers, using forms such as BMC-84 or BMC-85.

4. BOC-3

Check applicable process-agent information.

5. Business profile

If using a directory or company website, compare its claims with the official regulatory record.

A broker should not be evaluated using motor-carrier fleet metrics as though it operates the vehicles itself.

How to Check a Motor Carrier

For a motor carrier, a broader safety review may be appropriate.

Check:

• USDOT status
• Legal name
• Entity type
• Operating status
• Authority
• Power units
• Drivers
• Cargo classification
• Safety rating
• Inspections
• Driver OOS percentage
• Vehicle OOS percentage
• Crashes
• Regulatory history

The FMCSA Company Snapshot is designed to provide a concise record of company identification, size, cargo, inspection and out-of-service summary, crash data, and safety rating when available.

How to Check a Freight Forwarder

Freight forwarders are another category that should not automatically be treated as motor carriers.

Depending on the operation, check:

• USDOT record
• Entity classification
• FF authority
• Authority status
• Insurance or financial responsibility
• BOC-3
• Relevant safety information, where applicable

The applicable regulatory requirements depend on the company's actual operation.

What Is a BOC-3?

A BOC-3, or Designation of Agents — Motor Carriers, Brokers and Freight Forwarders, is a filing associated with process agents.

The filing designates agents who can accept legal process on behalf of the transportation entity in applicable states.

When verifying a company, BOC-3 information can therefore provide another useful regulatory data point.

However, a BOC-3 filing should not be confused with:

• Operating authority
• Insurance
• USDOT status
• Safety rating

Each represents a different part of the regulatory record.

What Is BMC-84?

BMC-84 is a surety bond filing used for applicable brokers and freight forwarders.

For property brokers, FMCSA's current financial-responsibility requirements specify a $75,000 bond or trust requirement, generally satisfied through BMC-84 or BMC-85.

The bond is not the same thing as cargo insurance.

That distinction matters.

What Is BMC-85?

BMC-85 is a trust fund agreement used as an alternative form of financial responsibility for applicable brokers and freight forwarders.

For applicable property brokers, FMCSA identifies BMC-84 or BMC-85 as the mechanisms for satisfying the $75,000 financial-responsibility requirement.

A BMC-85 should therefore not be described as a normal commercial insurance policy.

How to Check a Carrier's Safety Record

For a motor carrier, review the available safety information associated with its USDOT record.

Depending on the record, you may find:

• Inspections
• Violations
• Driver out-of-service data
• Vehicle out-of-service data
• Crashes
• Safety rating
• Compliance reviews
• Enforcement-related information

FMCSA's Safety Measurement System uses data from roadside inspections, crash reports, and investigations as part of its safety-monitoring framework.

However, individual safety data points should be interpreted carefully.

For example, a crash appearing in a record does not by itself establish fault.

Similarly, a safety rating is not a general customer-service rating.

How to Verify a Car Shipping Company

If you are checking an auto transport company, use the same regulatory principles.

Start with:

1. USDOT number

Confirm the number and legal identity.

2. MC number

Check applicable operating authority.

3. Entity type

Determine whether the business is actually a:

• Motor carrier
• Broker
• Broker/carrier combination
• Other entity

4. Authority status

Check whether applicable authority is active.

5. Insurance

Review applicable insurance filings.

6. BOC-3

Check process-agent information where applicable.

7. Safety

For a motor carrier, review available safety information.

8. Company information

Compare the regulatory record with the company's website, contract, quote, and other documents.

This can help identify inconsistencies before entering a transportation transaction.

What If the Company Gives You a USDOT Number That Doesn't Match?

Stop and investigate the discrepancy.

For example, suppose a company calls itself:

ABC Auto Transport

but the USDOT record for the number it provided belongs to:

XYZ Logistics LLC

That does not automatically prove wrongdoing.

There may be legitimate reasons for differences involving:

• DBA names
• Legal entities
• Corporate structures
• Recent name changes
• Separate carrier and broker entities

But the discrepancy should be understood before you rely on the number.

Compare:

• Legal name
• DBA
• Address
• Phone
• USDOT
• MC
• Entity type
• Authority

Can a Company Have Multiple MC Numbers?

Yes.

A company may have multiple operating authorities depending on its registrations and regulatory circumstances.

FMCSA explains that companies may need multiple operating authorities to support their planned business operations.

This means a verification system should not assume:

One company = one authority number.

A company may have multiple dockets or authority records that need to be evaluated separately.

Can a Company Have Both Carrier and Broker Authority?

Yes.

A business can have regulatory registrations associated with more than one transportation activity.

For example, a company may operate as a motor carrier while also holding broker authority.

When this occurs, the two roles should be kept distinct.

The company may:

• Operate its own equipment as a carrier
• Arrange transportation through other carriers as a broker

A proper verification should therefore identify the applicable entity classifications and authority types rather than reducing the company to a single label.

Why Entity Classification Matters

Entity classification is one of the most commonly misunderstood parts of transportation verification.

A record may represent:

Motor Carrier

or:

Broker

or:

Freight Forwarder

or a combination of transportation registrations.

The classification affects how you interpret:

• Fleet information
• Drivers
• Safety information
• Insurance
• Authority
• Bond requirements
• Operating responsibilities

For example, a broker may have no power units because it does not operate commercial vehicles.

That should not automatically be interpreted as missing carrier data.

It may simply be Not Applicable.

How to Verify a Transportation Company Properly

A strong verification process should follow a consistent sequence.

Identity

Confirm:

• Legal name
• DBA
• USDOT
• Address
• State

Classification

Determine:

• Motor carrier
• Broker
• Freight forwarder
• Combination
• Other

Status

Check:

• USDOT status
• Operating status
• Authority status

Authority

Review:

• MC
• FF
• MX
• Authority type
• Authority scope
• Grant date
• Authority history

Financial Responsibility

Review applicable:

• Insurance
• Bond
• Trust
• BMC filings

BOC-3

Check:

• Filing status
• Process-agent information

Safety

For applicable carriers:

• Safety rating
• Inspections
• Out-of-service data
• Crashes
• Other available safety information

Business Information

Finally compare the official regulatory record against:

• Website
• Contract
• Quote
• Email
• Phone
• Business name
• Address

This creates a much more complete picture than checking a single number.

Common FMCSA Lookup Mistakes

1. Checking only the company name

Similar company names can produce confusion.

Use the USDOT or MC number whenever possible.

2. Checking only the USDOT number

A USDOT number does not answer every authority question.

Review applicable MC, FF, or MX authority as well.

3. Assuming active means fully authorized

USDOT status and operating authority status are different.

4. Treating a broker like a carrier

A broker may not operate trucks and should not be evaluated using carrier fleet data.

5. Ignoring insurance

Authority and financial responsibility are related but separate records.

6. Ignoring BOC-3

For applicable entities, process-agent information is another part of the regulatory record.

7. Assuming a crash means the carrier caused it

Crash data should not automatically be interpreted as a finding of fault.

8. Treating reviews as regulatory evidence

Reviews are customer-generated information.

They do not replace FMCSA records.

9. Using outdated FMCSA instructions

FMCSA's registration system has changed significantly in 2026.

Current FMCSA guidance should be used for registration and account-management instructions.

FMCSA's 2026 Registration System: What Changed?

FMCSA introduced Motus, its modernized USDOT Registration System, in 2026.

FMCSA describes Motus as the new central system for applying for and managing USDOT numbers, operating authority, registration information, biennial updates, and related registration actions.

Existing USDOT numbers and existing docket numbers do not change simply because of the transition.

FMCSA also states that newly issued USDOT and operating-authority numbers are being randomized under the new system, while existing numbers remain unchanged. New authority registrations can receive individual docket numbers rather than relying on the previous combined-docket structure.

This matters when reading current and historical transportation records.

If you find an older guide explaining how to obtain an MC or USDOT number, verify that the instructions still reflect the current FMCSA registration environment.

Can You Trust Third-Party USDOT Lookup Websites?

Third-party tools can make transportation data easier to search and understand.

However, the underlying regulatory source matters.

For current regulatory verification, official FMCSA data should be treated as the primary source.

A third-party directory may:

• Simplify the information
• Add company-submitted data
• Add reviews
• Organize records differently
• Cache older information

Those features can be useful, but they should not overwrite or misrepresent the official regulatory record.

When the two conflict, users should be able to identify which information comes from FMCSA and which information comes from another source.

What Is TransportTrace?

TransportTrace is a transportation-company verification and directory platform designed to make FMCSA information easier to research.

The platform separates regulatory information from business-profile and community information.

Official regulatory layer

This includes information derived from FMCSA records, such as:

• USDOT
• Authority
• Entity classification
• Status
• Safety
• Insurance and financial-responsibility information where available

Business-profile layer

Companies can provide additional information such as:

• Website
• Services
• Business description
• Service areas
• Hours
• Photos
• Contact information

Community layer

Reviews and other community-generated information remain separate from official regulatory information.

This separation matters because a company profile should not be able to rewrite its federal regulatory record.

How to Check a USDOT or MC Number With TransportTrace

TransportTrace is designed to make the verification process easier.

You can start with information such as:

• USDOT number
• MC number
• Company name

The goal is to quickly identify the corresponding transportation entity and organize the relevant regulatory information in one place.

For a complete verification, do not stop at the first result.

Review:

Identity → Entity Type → USDOT Status → Operating Status → Authority → Insurance/Bond → BOC-3 → Safety → Business Information

That sequence helps prevent common identification mistakes.

Final Checklist: What to Check Before Working With a Transportation Company

Before hiring or doing business with a transportation company, consider checking:

Company Identity

• Legal name
• DBA
• USDOT
• Address

Registration

• USDOT status
• Entity classification
• Operating status

Authority

• MC / FF / MX
• Authority type
• Authority status
• Authority history

Financial Responsibility

• Insurance
• Bond or trust
• Applicable coverage
• Filing status

Process Agent

• BOC-3
• Process-agent information

Safety

• Safety rating
• Inspections
• Driver OOS
• Vehicle OOS
• Crash information

Business Information

• Website
• Phone
• Service description
• Company-provided information

Final Comparison

Compare what the company tells you with what its regulatory record actually shows.

If the information does not match, investigate the difference before relying on it.

Final Takeaway

Checking a USDOT or MC number is not simply a matter of finding a number in a database.

A meaningful FMCSA verification involves understanding the relationship between:

USDOT → Entity → Operating Status → Authority → Insurance/Financial Responsibility → BOC-3 → Safety → Business Information

A USDOT number identifies the transportation entity.

An MC, FF, or MX number can identify applicable operating authority.

Insurance and bond records address financial-responsibility requirements.

BOC-3 addresses process-agent designation.

Safety records provide another layer of regulatory information.

Each answers a different question.

That is why a proper transportation-company lookup should examine the complete applicable record rather than relying on a single status or identifier.

For carriers, brokers, freight forwarders, auto transport companies, shippers, and logistics businesses, understanding these records can make transportation research substantially more transparent.

Check the number. Verify the authority. Understand the record.
