Carrier Identity Theft
Fraudsters impersonating a legitimate carrier's MC/DOT identity — using its name, numbers, and forged documents — to book loads they then steal or double-broker. The defense is verifying that the contact info you're dealing with matches FMCSA-registered records. CarrierOk serves registered phone, address, and legal-name data Updated throughout the day.
Learn moreWhat is Carrier Identity Theft?
Carrier identity theft is a freight fraud scheme in which a bad actor impersonates a legitimate, well-rated motor carrier to book loads under that carrier's MC and DOT numbers. The fraudster typically presents the real carrier's authority documents and insurance certificates — all publicly obtainable or easily forged — but substitutes their own phone number and email address on the carrier packet and rate confirmation. Once the load is tendered, the freight is either picked up and stolen outright or re-brokered to an unwitting third carrier while the fraudster collects payment. The legitimate carrier often learns of the theft only when the broker calls about a missing load or an unpaid carrier files against the broker's bond. The scheme works because brokers vet the identity on paper — which belongs to a real, clean carrier — rather than the identity on the phone. The single most effective control is verifying every contact detail against the carrier's FMCSA-registered records: a dispatcher emailing from a lookalike domain or a phone number that doesn't match the registration is the classic tell. CarrierOk exposes registered telephone numbers, physical addresses, and legal names for every FMCSA entity, refreshed throughout the day, so mismatch checks can run automatically at onboarding and again at every load tender.
Why does carrier identity theft matter?
Insurance Underwriters
Identity-theft losses distort the record of the impersonated carrier — cargo claims and disputes may attach to an insured who never touched the freight, so claim investigation should confirm who actually hauled the load.
Freight Brokers
You bear the loss when a stolen identity books your freight — always call the carrier back at its FMCSA-registered phone number, not the number on the inbound packet, and treat recently changed contact details as a red flag.
Developers & Platforms
Build a contact-match gate: compare the phone and email on the carrier's submitted packet against telephone_number and physical_address from the CarrierOk profile, and route any mismatch to manual review before tender.

What is carrier identity theft in freight?
Carrier identity theft is when a fraudster impersonates a legitimate trucking company — using its real MC and DOT numbers, name, and forged insurance documents — to book loads from brokers. The fraudster substitutes their own phone and email on the paperwork, then steals the freight or re-brokers it while collecting payment. The impersonated carrier is usually unaware until the broker reports a missing load.
How do brokers verify a carrier's identity?
Compare every contact detail on the inbound carrier packet against the carrier's FMCSA-registered records. The registered phone number, physical address, and legal name are the anchor — if the dispatcher's number or email domain doesn't match, stop and call the carrier back at the registered number. CarrierOk's API returns these registered fields for any DOT number, updated throughout the day, so the mismatch check can run automatically in your onboarding and tender workflow.
What are the warning signs of a stolen carrier identity?
The most reliable signs: contact information that differs from FMCSA registration, email from a lookalike or free-mail domain, urgency to book high-value loads outside the carrier's normal lanes, refusal to take a callback at the registered number, and recently updated registration contact details on an otherwise long-established carrier. A well-rated carrier suddenly operating out of character is often not that carrier at all — it's someone wearing its identity.

DOT Number (USDOT Number)
A unique identifier assigned by the U.S. Department of Transportation to every motor carrier, broker, and freight forwarder in interstate commerce. The DOT number is the primary key for looking up safety records, insurance, and authority in FMCSA databases. CarrierOk indexes every DOT number on the federal register.
Double Brokering
The illegal practice of a broker or carrier re-brokering a load to another carrier without the shipper's knowledge or consent. Double brokering creates insurance gaps, liability exposure, and fraud risk. CarrierOk's risk signals and authority-type checks help identify carriers associated with double-brokering patterns.
Freight Fraud
The umbrella term for schemes that exploit the freight system to steal cargo or payment — double brokering, carrier identity theft, fictitious pickups, and chameleon carriers. Freight fraud is the systemic problem carrier vetting exists to solve. CarrierOk surfaces 50+ risk signals across every FMCSA-registered entity to flag fraud patterns before a load is tendered.
Load Board
An online marketplace where brokers post available loads and carriers search for freight — the spot market's central matching mechanism. Load boards are also the front line where unvetted carriers and fraud enter the supply chain. CarrierOk vetting turns a load-board match into a verified counterparty before the rate confirmation goes out.
