Every carrier registered with FMCSA lists a phone number and usually an email address. Most carriers have their own. But when we analyzed the census of 2,245,548 active carriers (data as of 2026-11-09), we found:
- 51,938 active carriers list a phone number that at least one other active carrier also lists.
- 37,564 active carriers list an email address shared with another active carrier.
- Some single phone numbers are listed by thousands of carriers.
Why carriers share contact details
There are innocent explanations, and plenty of them:
- Filing and compliance services that register carriers and list their own office number. This explains the numbers shared by hundreds or thousands of carriers.
- Family businesses running several related companies from one office.
- Dispatch services handling contact for several owner-operators.
And there are explanations that matter for fraud:
- Chameleon carriers: an operator shut down for safety or unpaid claims reappears under a new USDOT number but keeps the same phone.
- Fraud rings running many authorities from one phone or one email inbox.
- Hijacked identities: several stolen carrier records updated to the same fraudster's phone.
How to use the signal
A shared phone is a reason to ask one more question, not a verdict. Look at what else is true: is the authority new? Did the contact info change recently? Are the other carriers sharing that number active, revoked or out of service? A phone shared with one sibling company is different from one shared with a dozen carriers that were revoked last year.
