What is a chameleon carrier?
"Chameleon" is the industry's word. The regulation's word is reincarnated. Under 49 CFR 386.73, FMCSA "may determine that a motor carrier, intermodal equipment provider, broker, or freight forwarder is reincarnated if there is substantial continuity between the entities such that one is merely a continuation of the other," and that one is an affiliate of another "if the business operations are under common ownership and/or common control."
The motive is what makes it a chameleon rather than a new business. FMCSA can act against an entity that operated "under a new identity or as an affiliated entity" to avoid complying with an FMCSA order, to avoid paying a civil penalty, or to "avoid being linked with a negative compliance history." A separate rule, 49 CFR 385.1005, prohibits two or more carriers from using "common ownership, common management, common control, or common familial relationship" to "avoid compliance, or mask or otherwise conceal non-compliance, or a history of non-compliance."
The pattern is not rare. In 2012 GAO found "an increasing number of carriers with chameleon attributes, from 759 in 2005 to 1,136 in 2010," and that "18 percent of the applicants with chameleon attributes were involved in severe crashes compared with 6 percent of new applicants without chameleon attributes." At the time FMCSA vetted only bus companies and movers for these attributes; in February 2016 it expanded vetting to all new applicants, freight carriers included.
Can two companies use the same DOT number?
No. FMCSA's answer is direct: "The USDOT Number belongs to the same legal person forever and may not be sold, transferred, rented, or leased. FMCSA will inactivate USDOT Numbers upon discovery that the number is being used by anyone other than the assigned legal person." A company that wants a clean slate therefore needs a new registration, and a new registration is visible.
What looks like sharing is usually leasing. An owner-operator can lease a truck to a motor carrier and haul under that carrier's authority; FMCSA says such "equipment leasing arrangements between motor carriers and owner-operators remain permissible and are distinct from the prohibited sale, purchase, or lease of USDOT Numbers." During the lease the carrier "shall have exclusive possession, control, and use of the equipment" and "assume complete responsibility for the operation of the equipment," so the truck carries the leasing carrier's name and number, not the driver's own.
What is not leasing is identity theft. FMCSA defines it as when "entities use another motor carrier's assigned USDOT number, when not authorized to do so," and calls it a criminal act. That is why its advice at pickup is to "confirm the name and numbers on the truck that shows up to load are the same as the one with which you contracted." Numbers swapped on a truck at a truck stop are one of two things: a lease you can confirm with the carrier on record, or a problem. The double brokering guide covers verifying who you are actually dealing with.
What FMCSA can do about a reincarnated carrier
Under 386.73, FMCSA can order the new entity out of service, and it can issue "an order consolidating the records maintained by FMCSA concerning the current [entity] and its affiliated [entity] or its previous incarnation, for all purposes," so the old entity's record can be attached to the new number. An order "is effective on the 21st day after it is served" unless the carrier seeks review. Operating without the registration the law requires carries a minimum civil penalty of $13,676 per violation.
Disclosure is the front line. By statute an applicant is registered only if it "has disclosed any relationship involving common ownership, common management, common control, or common familial relationship" with another carrier, broker or freight forwarder in the preceding three years. FMCSA's 2026 registration system, Motus, adds identity checks: FMCSA partnered with IDEMIA for identity verification to "prevent fraud," and "to help prevent fraud, Motus will randomize all newly issued USDOT Numbers and operating authority docket numbers." Launching it on 19 May 2026, the Department of Transportation said "it's estimated that there are several thousand suspicious registration numbers tied to fraudulent carriers." See what Motus changed.
How to spot one from the registration
FMCSA decides whether a carrier is reincarnated, in a proceeding. A broker cannot, but can check the same kinds of facts FMCSA weighs. The factors listed in 386.73 include commonality of ownership and of officers and management, identity of "physical or mailing addresses, telephone, fax numbers, or email addresses," identity of equipment, and continuity of liability insurance policies. The ones visible in public records:
| What to check | Where it shows | What CarrierScrub reports |
|---|---|---|
| A new USDOT number registered at a revoked carrier's phone | The registration date on the SAFER snapshot, and the phone on both registrations | STOP when the new registration has a different name, with the revocation date and the gap in days. A re-registration under the same name is CAUTION. |
| A phone shared with a carrier whose authority was revoked | The phone on the SAFER snapshot | CAUTION, naming how many revoked carriers share it. |
| Recently granted authority | The authority grant date | Shown with the date. New entrants are under FMCSA's 18-month monitoring. |
| The same insurer and policy moving from an old carrier to a new one | The carrier's insurance filing history | Three or more insurers in the history is CAUTION. |
| Same address, officers or equipment | The SAFER snapshot and the carrier packet | Not checked. Compare the packet yourself. |
In FMCSA's files as of 14 May 2026, 472 of the 379,060 carriers with active authority had registered at the phone of a carrier after that carrier's revocation was served, under a different name; 99 did so within 30 days. Another 3,528 shared a phone with a revoked carrier. The Q3 2026 fraud signals report breaks these down by state.
A shared phone is a question, not a verdict
Most shared contacts are innocent. A company runs two entities from one office; a family operates two trucking businesses; an owner re-files the same business under a corrected registration. CarrierScrub's own sampling found legitimate corporate families behind many shared-phone matches, which is why it never calls a company a chameleon. It states the registration facts with their dates and leaves the judgment to you, and a legal finding to FMCSA.
The timing is what separates the patterns. A second company that has shared a phone for years is a different fact from a new USDOT number registered at a phone days after the carrier behind it had its authority revoked. That is the one relationship CarrierScrub treats as a STOP: not because it proves reincarnation, but because it is the pattern 386.73 exists for, and a load should wait until you have asked.
