The Problem: The Carrier You Vetted Is Not Always the Carrier You Get
Most carrier onboarding still comes down to three checks: is the authority active, is insurance on file, and does the safety rating look acceptable. A carrier that passes all three gets set up and starts hauling.
The trouble is that the two most expensive fraud patterns in brokerage today pass those checks easily.
- Chameleon carriers shut down one DOT/MC number — usually after bad inspections, claims or an out-of-service order — and come back under a fresh number. Same owner, same phone, often the same yard. The new authority has no history, so it has nothing bad on it.
- Double brokering happens when a party accepts your load as a carrier and quietly re-brokers it to someone else, or when a fraudster takes over the identity of a real, established carrier by changing its contact details and booking loads in its name. You pay the wrong party, the real hauler goes unpaid, and the freight is at risk.
In both cases the question is not "is this authority active?" It is "who is actually behind this authority, and what else are they connected to?"
How Fraudsters Leave a Trail
Creating a new MC number is cheap. Creating a completely new identity every time is not. Operators reuse what they already have, and that reuse is visible in public registration data:
- Phone numbers — the same cell number appears on two, three or ten registrations.
- Email addresses and domains — a personal Gmail or a small custom domain shared across "unrelated" carriers.
- Physical and mailing addresses — the same suite, house or truck stop address behind several authorities.
- Officers — the same principal listed on a revoked carrier and a brand-new one in the same state.
- DUNS numbers — business identifiers that carry over from one entity to the next.
Identity takeovers leave a different trail: an established carrier that suddenly changes its phone, email or mailing address, sometimes along with officers, right before loads start disappearing.
Neither pattern shows up in a single snapshot of one carrier. You see it when you link carriers to each other and watch for changes over time.
The Signals That Actually Matter
Not every link is suspicious. Here is how to weigh what you find:
| Signal | Why it matters | How much weight |
|---|---|---|
| Shares a phone, email or address with an inactive or revoked carrier | Classic chameleon pattern — the old authority went away, the operation did not | High |
| Recent contact or address change on an established authority | Common sign of identity takeover before double brokering | High |
| Very new authority that links to several other carriers | New numbers with deep connections deserve a phone call | Medium–High |
| Officer change shortly after authority was granted | Can indicate a sold or rented authority | Medium |
| Insurance cancellation or pending suspension | Coverage may lapse while your load is on the truck | Medium |
| Shares an identifier with a filing service or registered agent | Thousands of legitimate carriers use the same agent | Low — ignore |
| Officer name match in a different state | Usually a namesake, not the same person | Low — ignore |
The last two rows matter as much as the first ones. A vetting tool that flags every carrier using a popular filing service will bury your team in false alarms, and they will stop looking.
A Practical Vetting Workflow
You do not need to investigate every carrier. You need a fast routine that sends the right ones to a closer look.
- Look up the DOT or MC number before the first tender, not after the load is booked.
- Compare the contact on the rate confirmation with the registration on file. If the dispatcher's phone or email does not match FMCSA records, call the number on file — not the one you were given.
- Check recent changes. Any phone, email, address or officer change in the last 30–60 days on an older authority is a stop-and-verify moment.
- Review linked carriers. Are any of them inactive, revoked or recently suspended? How many share the same phone or address?
- Decide and document. Clear the carrier, ask for more verification (a call-back, a video call from the cab, a W-9 matching the legal name), or decline. Save the result in the carrier file.
- Keep watching after onboarding. Most identity takeovers hit carriers you already approved. A carrier that was clean in March can change its email in October.
How the Carrier Identity Graph Helps
The Freight Data Watch Carrier Identity Graph was built around exactly this workflow. It links about 710,000 active carriers by their shared identifiers and logs every change in their public FMCSA records.
- Search any way you have it — DOT number, MC number, company or officer name, phone number, email address or email domain.
- See who a carrier is connected to — linked carriers by shared phone, email, address, officers and DUNS, including inactive carriers that went away.
- Filing-service filter — identifiers shared by large numbers of carriers (registered agents, filing services, very common officer names) are labeled and excluded from links, so you see real connections instead of noise.
- Change history — new registrations, contact, address, officer and name changes, authority events, insurance cancellations and suspension notices, synced nightly. History starts October 16, 2026 and grows every day.
- A clear review level — each report summarizes its signals as Low, Review, Elevated or High so your team knows which carriers need a phone call.
The free preview shows the top links and recent changes for any carrier. Broker teams with an access key get full reports, a watchlist of the carriers they work with, email and webhook alerts when a watched carrier changes its contact details, authority or insurance, and a REST API to run checks from a TMS or onboarding system.
One important note: the Identity Graph does link analysis and change alerts. A link or a change is a reason to verify — it is not an accusation. Plenty of legitimate fleets share an office with a sister company or update their phone number for ordinary reasons. The goal is to make sure the right carriers get a second look before you hand them a load.

Public FMCSA data has limits, and it is better to know them up front:
- No VIN matching. Registration data does not include vehicle identification numbers, so truck-level matching is not possible from public records.
- No private data. Links come only from public registration, authority and insurance filings — not from load boards, payment records or other brokers.
- History is new. Change tracking began October 16, 2026. Older changes are not in the log, although inactive and revoked carriers can still appear as links.
