Counts are by domicile state in the FMCSA census and recomputed hourly. A new USDOT registration is a number added to the census this month (registration, not an authority grant). A cancellation counts only when the insurer has filed it and the effective date is on record. A renewal counts only when the estimated X-date is reliable and no cancellation is pending.
Every for-hire carrier based in South Carolina that crosses a state line files with FMCSA: its census registration, its operating authority and proof of liability insurance (the BI/PD filing). A DOT lead is what happens when one of those changes. A new USDOT number means a first-time buyer with no incumbent agent. An insurer-filed cancellation means a carrier that must replace coverage by a known date or lose its authority. A renewal date inside your window means the incumbent is about to re-market the account.
Most DOT-leads products sell South Carolina as a weekly list licensed by state. The data under every one of them is the same public record; what differs is how often it is read and what comes with the USDOT number. Market Tracker reads every publish, so a South Carolina cancellation filed yesterday is a lead today, and the row carries the contacts, fleet, cargo, current insurer and safety record.
The lists below are a free sample of two of the three signals, straight from the record. Renewal dates stay inside the product. For the market view of South Carolina (the largest insured fleets and the cargo segments), see South Carolina trucking insurance leads.
Nothing here is a bought list. The record publishes, we compare it with yesterday, and the changes become dated leads.
Insurer-filed cancellations on carriers still active, effective in the next 60 days; insurer changes are left out. The cancelling insurer, contacts and the full list are in Market Tracker.

No. One seat covers every state and every lead type: $99 per user per month, or $69 per user per month billed yearly, with a free trial.
A renewal date is an estimate, and the incumbent usually renews. A filed cancellation is the insurer telling FMCSA that coverage ends on a set date; the carrier must replace it or lose its authority about 30 days later. It is the hardest-dated lead on the record.
