Effective November 8, 2026
CarrierTell is a browser extension that shows risk information from public Federal Motor Carrier Safety Administration (FMCSA) records next to USDOT and MC numbers on web pages. We built it to collect as little data as possible.
CarrierTell scans the visible text of the page you are viewing on your own device to find USDOT and MC number patterns. Page contents are never sent to us or to anyone else.
To look up a number, the extension downloads a whole block of public carrier records (thousands of carriers at a time) from data.carriertell.com. The request doesn't say which carrier you are checking, so we can't tell which carriers you looked up. Like any website, our hosting provider may keep standard request logs, such as IP address and the time of the request, for security. We don't use those logs to profile anyone.
Your settings (badges on or off, data source) and a daily counter of free lookups are kept in your browser's extension storage. They never leave your device.
Pro subscriptions are handled by ExtensionPay and Stripe. They collect the email address and payment details needed for billing. CarrierTell never receives your card details.
We do not sell or share personal data. We do not use data for advertising, credit or lending decisions, or any purpose other than running the extension. We do not track your browsing.
Carrier information comes from public FMCSA records published on data.transportation.gov. We also keep our own daily history of how those public records change. Risk levels are automated signals, not statements of fact about any company. Always verify a carrier before doing business with it. Carriers who believe a record is wrong should correct it with FMCSA. We'll fix any error of our own that you report.
