Related Carriers With Separate USDOT Numbers: Keep Each Record Its Own

Why one business can hold several USDOT numbers

FMCSA’s policy is that each separate and distinct person must have separate registration, and that a USDOT number belongs to one legal person permanently. A parent company with three operating subsidiaries can therefore have three or four USDOT numbers, each with its own authority, insurance filings, inspections and crashes.

For a load, the record that matters belongs to the entity on the rate confirmation that will operate the truck. Its authority status, its insurance filings and its safety record answer the booking question. The relationship between USDOT and docket numbers is covered in the guide to DOT and MC numbers for brokers.

When FMCSA joins two records

Under 49 CFR 385.1005, two or more carriers may not use common ownership, management, control or family relationship to avoid compliance or to hide non-compliance or a history of it. FMCSA may find that carriers are reincarnated, where one is merely a continuation of the other, or affiliated, where they are under common ownership or control, and suspend or revoke their registration.

Under 49 CFR 386.73, FMCSA may also issue an out-of-service order, or an order consolidating the records of the current carrier with its affiliate or previous incarnation for all purposes. Both require a finding that the new or affiliated entity was used to evade an order, a requirement, a penalty, an enforcement action or a negative compliance history.

Until FMCSA makes that finding, the records stay separate, and a broker should keep them separate too. Shared ownership is lawful. Writing a sister company’s out-of-service order into another carrier’s file as if it were that carrier’s record is the error the regulation reserves for an agency determination.

Use FMCSA’s factors as questions, not a verdict

Section 386.73(c) lists factors FMCSA may weigh when deciding whether a carrier is a continuation or affiliate of another. They make a useful set of questions when two USDOT records look connected. One factor is the stated business purpose for creating the new entity, so ask for it.

• When was each company created, and did one stop operating as the other started?
• Do they share owners, officers or managers?
• Do they share a physical or mailing address, phone number or email address?
• Do the same trucks, drivers or insurance policies appear under both?
• Do they serve the same customers and hold themselves out under similar names?
• What was the older company’s safety and enforcement history when the newer one began?

Read the answers by pattern

A long-established parent with several subsidiaries that have operated in parallel for years is an ordinary structure. A newly registered company that appears as an older one with an out-of-service order or a poor record stops operating, using the same address, trucks and drivers, matches the pattern 386.73 describes. Most cases fall between, and the answer should name the relationship rather than score it.

A shared address or phone number is where the question usually starts. What a match on the full address does and does not show is covered in the guide to a shared carrier address, and how to avoid joining two businesses on a similar name is covered in the guide to matching a carrier to government records.

When the newer company is the one offering the truck, review it on its own short record. The older company’s history is a reason to ask more questions, not a substitute for the newer company’s evidence.

Keep the review on the entity that hauls

A recommended check: the rate confirmation, carrier packet, insurance certificate, W-9 and remittance details should all name the same legal entity and USDOT number. If a sister company owns the trucks or employs the drivers, ask how the equipment is provided; FMCSA distinguishes leasing equipment under 49 CFR Part 376, which is permitted, from using another company’s USDOT number or authority, which is not.

VerifyCarrier’s lookup returns one USDOT record at a time, so look up each entity separately and save each result under its own number. At pickup, confirm that the truck and paperwork match the company you contracted, not its affiliate.

An illustrative review note: “Carrier A and Carrier B (separate USDOT numbers, both recorded in the file) share an owner and yard; B registered in 2019, A in 2011, both active. Load contracted to A; A’s own record reviewed; B’s record not used. Trucks titled to B and leased to A under a written lease, copy on file.”
