Know the second a carrier
loses its insurance or authority.
Paste a list of USDOT numbers and your email. We check each carrier against the federal FMCSA record every day and email you the moment BI/PD insurance is cancelled, coverage drops below the federal minimum, or operating authority is revoked.
How it worksA list in.
A list in.
An alert the day it matters.
Insurance cancellations and authority revocations don’t announce themselves — they just show up in the FMCSA record. We watch that record for you and turn a change into an email, so a lapsed carrier never slips onto a certificate or through a renewal unnoticed.
02
Confirm once
We email you a confirmation link. Click it and monitoring starts — that single step keeps the list clean and the alerts landing in your inbox, not your spam folder.
03
We watch, you get alerted
Every day we re-check each carrier against the FMCSA federal record. The moment BI/PD insurance is cancelled or falls below the required minimum, or operating authority is revoked or goes inactive, you get an email.
FAQ
The honest answers.
What exactly does the carrier insurance monitor watch for?
The Native Base carrier monitor checks each USDOT number against the FMCSA federal licensing-and-insurance database once a day and emails you on any of these changes: BI/PD (bodily injury / property damage) liability insurance dropping off file — i.e. a cancellation or lapse; BI/PD coverage on file falling below the federally required minimum for that carrier; operating authority (common, contract, or broker) going from Active to Revoked, Vacated, or Inactive; and a revocation becoming pending. These are the events that mean a carrier you cover, are about to quote, or have on a certificate is no longer legally able to operate.
Where does the data come from?
Straight from the federal FMCSA licensing & insurance datasets published on data.transportation.gov — the same source of truth FMCSA uses for operating authority and the BMC-91/BMC-34/BMC-82 insurance filings on file. The lookup is anonymous and we don’t modify the federal data.
How fast will I find out about a cancellation?
We re-check every monitored carrier daily, so you’ll typically know within 24 hours of the change appearing in the FMCSA record. Insurance and authority status don’t change minute-to-minute, so a daily sweep catches cancellations and revocations well before a renewal or audit would.
Why do I have to confirm my email first?
A single confirmation click (double opt-in) keeps the monitor list clean and protects your deliverability — it means alerts about a real cancellation actually reach your inbox instead of being filtered as bulk mail. Until you confirm, nothing is monitored. You can unsubscribe from any alert email with one click.
Can you monitor my whole book of business automatically?
Yes — this free tool watches up to 25 carriers per subscription, but the same engine runs at any scale. If you want your entire book monitored continuously and the cancellations flagged directly inside your AMS (so a CSR sees it on the account, not just in an inbox), that’s exactly what Native Base builds. Reply to any alert email or book a call and we’ll wire it into your stack.
Monitoring a whole book?
One paste watches 25 carriers.
Your AMS should watch all of them.
A cancellation alert in an inbox is good. A cancellation flagged on the account inside your AMS — where the CSR servicing it will actually see it — is better. We can monitor your entire book continuously and push the changes straight into your system, alongside our FMCSA, MOTUS, SOS, and vPIC stack.
