# Chameleon carriers: how to find related entities in FMCSA data

*A practical method for spotting reincarnated carriers with public data, including which matches mean something and which only point to a shared filing service.*

Category: Fraud & verification. Published 2026-10-19, updated 2026-10-19. By Isaac Welch.

## Key takeaways

- A chameleon carrier reopens under a new name and USDOT number to escape its record, usually keeping the same owners, address, phone, trucks or drivers.
- FMCSA can treat a new entity as a reincarnation when there is substantial continuity with the old one, weighing factors such as shared officers, addresses, phones, email, equipment and insurance.
- The strongest public-data signal is several independent rare matches, such as an officer plus a phone or address, to a carrier that was revoked or put out of service shortly before the new one registered.
- Shared contact data only means something when it is rare: the most common phone number among active FMCSA census records appears on 2,981 USDOT numbers.
- Motus identity proofing makes fake new registrations harder, but it does not stop a real person from opening a new company to leave an old record behind.

## What is a chameleon carrier?

A chameleon carrier is a trucking company that abandons a USDOT number with a bad record and reopens under a new name and number, usually with the same owners, managers, address, phone, trucks or drivers, to escape out-of-service orders, penalties, a poor safety history or unpaid debts. FMCSA's rules call these reincarnated carriers, and 49 CFR 386.73 lets the agency order the new entity out of service or consolidate its records with the old one.

The test in the rule is substantial continuity between the entities, such that one is merely a continuation of the other. Among the factors FMCSA may weigh are common ownership, common officers and management, identity of physical or mailing addresses, telephone, fax numbers or email addresses, identity of equipment, continuity of insurance, shared drivers and employees, and the dates the companies were created and dissolved.

Most of the identity factors on that list (addresses, phones, email, officer names and dates) sit in FMCSA's public census file. That is what makes related-entity matching practical for a small factor without special access. The glossary has a short definition of a [chameleon carrier](https://carrierkyc.com/glossary/chameleon-carrier).

## Why should a factor care about chameleon carriers?

Safety regulators care about crashes. A factor cares because the behavior that sheds a safety record also sheds debts. A carrier that owed a prior factor, ran up chargebacks, or sat under a UCC lien can reappear as a new LLC with no lien, no history, and the same people running it.

The new entity also brings the old operation's habits: the same equipment, the same approach to paperwork, and the same willingness to walk away. Because new USDOT numbers are now randomized (carriers added to the census on the same day in October 2026 span the 4 millions to the 9 millions), you can't spot the new entity by its number either. You have to read dates and links.

GAO flagged the gap in 2012, recommending that FMCSA build a data-driven, risk-based vetting method that compares new applicants with carriers that had enforcement problems, looking at shared ownership, officers, addresses and phone numbers. The same idea works on a factor's desk at a smaller scale.

## How has FMCSA tried to catch chameleon carriers?

After the GAO report, Congress funded an automated screen. FreightWaves reported in December 2025 that FMCSA's Application Review and Chameleon Investigation system (ARCHI) scored new applications for similarity to existing carriers using names, addresses, phone and fax numbers, FEINs, owner and key personnel names, VINs and commercial relationships. By 2016 it had screened nearly 90,000 applicants and flagged about 8,000, according to that reporting, but FreightWaves could not confirm whether it is still running.

Motus adds identity proofing for new registrants, plus business verification that validates ownership structure and company officials, according to FMCSA's April 2026 Federal Register notice. That makes a fake company harder to register. It does not stop a real owner from registering a new company under their own real name, which is exactly what a chameleon does.

The practical point: don't assume FMCSA caught it. An order under 386.73 comes after an investigation, and a reincarnated carrier can apply to you long before that.

## How do you find related entities in FMCSA data?

Start with the applicant's census record, then search the rest of the census for the same values. The census holds active, inactive and pending entities, so old, inactive and revoked carriers are still there to be matched.

*Census fields worth matching*

| Signal | Census fields | Strength | Watch out for |
| --- | --- | --- | --- |
| Officer names | `company_officer_1`, `company_officer_2` | Strong when the name is uncommon | Common names and spelling variants |
| Phone numbers | `phone`, `cell_phone`, `fax` | Strong when the number is rare | Filing services and compliance firms listed on hundreds of records |
| Email | `email_address` | Strong for a personal address or a company domain | Shared webmail domains: match the full address, not the domain |
| Physical address | `phy_street`, `phy_city`, `phy_state`, `phy_zip` | Medium to strong | Truck stops, virtual offices and registered-agent addresses |
| Mailing address | `carrier_mailing_street` and related fields | Medium | PO boxes and mail drops |
| Prior revocation link | `prior_revoke_flag`, `prior_revoke_dot_number` | A direct pointer when set | Rare: only 138 records carried `Y` when we queried on 2026-10-19 |
| Timing | `add_date` compared with the old entity's revocation or inactivation date | Strong in combination with other matches | Legitimate restructurings also create new entities |

Then look up the status of every entity you matched. The outcomes that matter are revoked or suspended authority (in the legacy revocation file and Motus RevokeSuspend), an out-of-service order in FMCSA's OOS orders dataset, an unsatisfactory safety rating, or an inactive USDOT. A new carrier linked to one of those, and registered soon after, is the classic pattern.

### Querying the census yourself

The census is open on data.transportation.gov and answers simple filters over its SODA API with no key. A query such as `/resource/az4n-8mr2.json?$where=phone='5555550123'&$select=dot_number,legal_name,status_code,add_date` returns every USDOT listing that phone, active or not. Swap in `cell_phone`, `email_address` or `company_officer_1` to match the other fields.

Mind the quirks. Every column is text, census dates are written `YYYYMMDD`, and the legacy L&I files write dates as `MM/DD/YYYY` and pad `dot_number` with leading zeros, so strip the zeros before you join a legacy revocation to a census record. The legacy files stopped updating on 2026-05-14, so check Motus RevokeSuspend for anything since.

## What does a related-entity match look like in practice?

Here is a fictional example. Example Carrier LLC applies to factor in September 2026, and its census record shows an `add_date` in April 2026, one power unit, and a single officer, Jordan Sample. The authority is active, insurance is on file, and there are no inspections yet, so nothing on SAFER looks wrong.

A search on the officer name returns Sample Freight Inc, now inactive. Its cell phone matches Example Carrier's, and its authority was revoked in February 2026 after an insurance cancellation, with an out-of-service order before that. Searching the shared physical address returns 2 more inactive carriers, both registered by the same officer.

That is three independent rare matches (officer, cell phone and address) to entities that went bad shortly before the new one appeared. It doesn't prove Example Carrier LLC is a reincarnation, but it changes the conversation. Ask Jordan Sample what happened to Sample Freight, check for UCC liens and unpaid factors under both names, and decide with the answer in the file.

## Which matches are meaningful, and which are noise?

Rarity is everything. When we queried FMCSA's census on 2026-10-19, the single most common phone number among active records appeared on 2,981 USDOT numbers, and the next two on 1,549 and 1,363. Those are almost certainly registration or compliance services, and a match on one of them tells you nothing about the carrier.

Weight each match by how rare the value is, and cap or ignore values shared by more than a few dozen carriers. One rare match can be coincidence, such as a family business or a shared yard. Two or three independent rare matches to the same bad entity is a pattern.

> **Red flag: The classic chameleon pattern** A new USDOT whose `add_date` falls within a few months of another carrier's revocation or out-of-service order, sharing an officer name plus a phone or address with it, applying to factor with a short, clean history and no UCC filings.

There are honest reasons for overlap. Owners restructure, buy a competitor's trucks, or start over after a business genuinely failed. Ask the applicant directly and compare the answer with the records; a reincarnation usually comes with a story that never mentions the old company.

## What steps should a factor follow?

1. **Pull the applicant's record** Note officers, phone, cell, email, physical and mailing addresses, `add_date` and `mcs150_date`.
2. **Normalize the values** Use digits only for phones, lowercase for email, standard street abbreviations, and strip LLC, Inc and similar suffixes from names.
3. **Search for matches** Query the census for each value, or run the free [carrier check](https://carrierkyc.com/tools/carrier-check), which counts other USDOT numbers sharing the census phone, email or physical address and splits them by status.
4. **Drop the noise** Ignore values shared by many carriers and keep the rare ones.
5. **Check the matched entities** For each, review status, revocations and suspensions, out-of-service orders, safety rating and dates.
6. **Search liens under every name** Run a [UCC search](https://carrierkyc.com/tools/ucc-search) on the applicant and on each linked entity, since a prior factor's lien may sit under the old company's name.
7. **Ask and document** Ask the applicant about each link, record the answer and your decision, and keep the evidence in the file.

## How are chameleon carriers different from MC takeovers and identity theft?

They use similar tools, but they differ in who is behind the record, and that changes which check catches them.

*Three schemes, three different checks*

| Scheme | The people | The record | What exposes it |
| --- | --- | --- | --- |
| Chameleon carrier | The same operators as the old company | A new USDOT number and name | Links to the old entity: officers, contacts, equipment and timing |
| Identity theft or account takeover | Strangers | A real carrier's existing record | Contact changes, callbacks to verified numbers, identity checks |
| Bought MC or fake ownership change | New operators who paid for, or claim, the identity | An aged record with new people and contacts | Ownership documents that don't hold up, officer and contact changes |

The other two have their own guides: [carrier identity theft](https://carrierkyc.com/guides/carrier-identity-theft) and [change-of-ownership and bought-MC fraud](https://carrierkyc.com/guides/change-of-ownership-fraud).

## Is it illegal to close a trucking company and start a new one?

Not in itself. Owners close businesses, restructure and start new ones for ordinary reasons. Under 386.73, the question is whether the new entity is a continuation of the old one, operated to avoid orders, regulatory requirements, penalties, enforcement or a negative compliance history.

For a factor, the legal label matters less than the credit question: is this the same operation, and did it walk away from its obligations last time? This is general information, not legal advice; talk to counsel before acting on a suspected reincarnation.

## Frequently asked questions

### Why are they called chameleon carriers?

Because they change their appearance, a new name and number, while staying the same underneath. FMCSA's regulations use the term reincarnated carriers for the same idea.

### Does FMCSA publish a chameleon flag I can check?

FMCSA does not publish a chameleon score. The public census does include `prior_revoke_flag` and `prior_revoke_dot_number` fields, but they are set on very few records, so most cases need your own matching.

### Do chameleon carriers keep their old insurance?

Sometimes. Continuity of liability insurance is one of the factors FMCSA weighs, so ask the agent whether the insured, the vehicles or the drivers moved over from another policy or another named insured.

### How far back should I look for related entities?

Inactive records stay in the census, so you can match against the whole file. Weight recent links most: an entity that was revoked or went inactive within a year or so of the new registration matters more than one from a decade ago.
