Introduction

Hiring someone to move your car means trusting a company you may never have used before. A business's proper registration, authorization, and insurance are not demonstrated by a low quote or a good website.

The USDOT and MC numbers are important in this situation. They enable you to verify the identity of the company, the power it possesses, and whether the federal record corresponds with what you were informed. 

What Are DOT and MC Numbers?

In FMCSA records, a motor carrier or other regulated transportation company is identified by its USDOT number, which is used for registration and safety monitoring.

The interstate operating authority is linked to an MC number. While not all businesses need both, many for-hire interstate carriers and brokers require both operating authority and a USDOT number.

Why Verification Matters

Sometimes a valid carrier's DOT or MC number is copied by scammers and used on a phony website. Others use corporate details that don't match federal records or advertise under an inactive authority.

Thus, inquire beyond just "Do you have a DOT number?" Check it for yourself.

Together, the entity type, phone number, address, legal name, and functioning status should make sense. Stop there if the number is owned by another business. A federal number is only helpful if the seller's details match. 

Where to Check

  • FMCSA's SAFER Company Snapshot is a good place to start. You can search by company name, MC number, or USDOT number. The record displays entity type, operating status, firm information, and available safety data.
  • Use the FMCSA's Licensing and Insurance system for operating authority. Here, you can examine authority history and insurance files, as well as determine whether authority has been granted. 

How to Check a DOT Number

Here are easy-to-follow steps to check a DOT number

  • In SAFER, enter the USDOT number.
  • Compare the company's website, quote, and contract with the legal name, DBA name, address, and phone number. A legitimate number linked to several company details raises suspicions.
  • Next, look up the USDOT status. A company's ability to conduct interstate for-hire transportation is not guaranteed by an active USDOT registration.
  • Examine the entity type as well. Transportation is arranged via a broker. The truck is driven by a carrier. Ask questions before making a reservation if a company claims to be the owner of the vehicles, but the federal record only lists it as a broker. 

How to Check an MC Number

Here are easy-to-follow steps to check an MC number

  • In the FMCSA's Licensing and Insurance system, look for the MC or USDOT number.
  • Verify that the authority status is appropriate for the service being provided. It is important to pay attention to pending, revoked, or inactive authority for interstate for-hire vehicle transportation. For this check, users are directed to the Authority Status column by FMCSA's own search instructions.
  • The granting or revocation of operating authority can also be seen in the authority history.

Red Flags to Watch

There are some basic things you need to take note of when you are checking

  • Refusing to give a DOT or MC number is a clear red flag. This also applies to a number that belongs to another company.
  • Keep an eye out for mismatched addresses, expired or revoked authority, pressure to pay right away, and a business posing as a carrier when it is simply registered as a broker.

Verification should be done before comparing extras like enclosed or open auto shipping when selecting an auto transport business. 

How to Verify Insurance

A current DOT number may not guarantee coverage for all kinds of losses.

Required insurance filings related to operating authorization are displayed in FMCSA's Licensing and Insurance records. Federal filing requirements for regular for-hire property carriers typically deal with public liability coverage; non-household-goods property carriers are exempt from federal regulations for cargo insurance.

Find out what coverage is applicable to cars under the carrier's control by requesting a current certificate of insurance. 

Keep the certificate with your other shipping documents.

Check More Than Registration

You can determine whether the company's credentials match by looking at federal records. They don't tell you how well it manages issues or communicates.

Examine current reviews on various platforms. Keep an eye out for recurring grievances regarding refunds, unexpected pricing adjustments, missed pickups, or damage claims. If the BBB profile is accessible, review it. 

Questions to Ask Before Booking

  • Find out whether the business is a carrier or a broker, who will actually transport the automobile, when the carrier will be assigned, and what insurance applies.
  • Inquire about the terms of cancellation, when payment is due, and whether the quote is subject to change. These checks prevent scams. 

Conclusion

It just takes a few minutes to verify a DOT and MC number, but before you turn over your car, those minutes could reveal an inactive business, a mismatched identity, or a lack of authority.

First, make sure. Next, contrast the cost, level of service, and time.

Verify the federal record before making a deposit, regardless of the carrier you choose.

FAQ

What is the difference between a DOT and MC number?

A USDOT number identifies a company for registration and safety monitoring; an MC number relates to federal operating authority.

Can a carrier operate without an MC number?

Yes, in some situations. MC authority depends on the type of transportation and the company's operating locations.

How do I verify carrier insurance?

Check FMCSA's Licensing and Insurance records and request the carrier's current certificate of insurance.

What if a company refuses to provide its DOT number?

Do not book until you can independently verify any registration the business is required to hold.

Are broker DOT and MC numbers different from carriers?

Yes. Brokers and carriers are separate entities and should be checked according to the authority each one holds.
