What this lookup shows, and why it matters
Authority and status
Whether the carrier is allowed to operate, and whether its for-hire authority is active. Brokers and shippers check this before they tender a load.
Insurance on file
Which insurance companies filed for you, how much, and since when. If a filing is missing, short, or pending cancellation, your authority can be revoked.
Safety data
Inspections, out-of-service rates and crashes. Insurance underwriters look at the same numbers when they price your policy.
How to find a DOT or MC number
- Look at the truck. The USDOT number is marked on both sides of the power unit.
- Check your paperwork. It's on your MCS-150 and your FMCSA registration letters. Your MC number is on your authority grant.
- Run the lookup. Choose USDOT or MC above and enter the numbers only.
Quick answers
What's the difference between a USDOT number and an MC number?
A USDOT number identifies a company's safety record with FMCSA. An MC number is the operating authority a for-hire carrier needs to haul regulated freight across state lines for pay. Many carriers have both.
Why does my insurance not show up on file?
Your insurance company has to file a BMC-91 or BMC-91X with FMCSA, and it can take a few days to post. If it's been longer, or your policy changed, call us and we'll check the filing.
My power units or drivers look wrong. How do I fix them?
Those numbers come from your MCS-150. Update it with FMCSA. You must update it at least every two years and whenever your operation changes.
Does a low out-of-service rate help my insurance?
Yes. Underwriters look at your inspection results. Fewer out-of-service orders and crashes generally mean more carriers will quote and better pricing.
Is this the official FMCSA website?
No. Redline Insurance is an independent insurance agency. This tool shows public data from FMCSA. For official records, use FMCSA's SAFER system.
