What the main fields mean
From FMCSA's SAFER help page:
- Entity type: carrier, hazmat shipper, both, or registrant
- USDOT status: ACTIVE means the number is active. OUT-OF-SERVICE means the carrier is under an out-of-service order and can't operate. Inactive can mean the biennial MCS-150 update wasn't done
- Legal name: the legal name of the company
- DBA name: a trade name the company does business under
- MC/MX/FF number: the docket number for interstate for-hire operating authority
- Operating authority status: AUTHORIZED FOR property, passenger or household goods, or NOT AUTHORIZED, which means no for-hire authority. NOT AUTHORIZED doesn't apply to private or intrastate carriers
- Carrier operation: interstate, intrastate only (hazmat), or intrastate only (non-hazmat)
- Power units and drivers: fleet size as reported on the MCS-150
- MCS-150 form date: when the registration was last updated
- Inspections, out of service, crashes, safety rating: the last two years of roadside inspections and crash counts, plus any Satisfactory, Conditional or Unsatisfactory rating
Check your own record before you letter the truck
Under 49 CFR 390.21, the name on your doors has to be your legal name or a single trade name as listed on your MCS-150, followed by "USDOT" and your number. So the SAFER record is the source of truth for your lettering. Before you order:
- Copy the legal name or DBA exactly as SAFER spells it, including INC or LLC if you're using the legal name
- Double check every digit of the USDOT number
- Make sure the status is ACTIVE
If the name is wrong on SAFER, fix the record first. Read legal name vs DBA on the truck door for which one to use.
If something on SAFER is wrong
Name and address changes go through an updated MCS-150, which FMCSA says is free. You can do it online with your USDOT PIN or submit the form through FMCSA's contact center. After FMCSA processes a name change, allow 24 to 48 hours for it to show on SAFER. If you also have an MC number, that's a separate change on form MCSA-5889, and as of October 2026 FMCSA lists a $14 fee for it. See MCS-150 biennial update.
Then order the lettering
Once the record is right, type the name and number into our USDOT truck lettering designer. You'll see a live preview on a photo of your truck type before you order, and it ships as one pre-spaced cut vinyl sheet per door.
Related questions
Is the SAFER lookup free?
Yes. FMCSA's Company Snapshot is free, one carrier at a time.
Can I look up a carrier by name?
Yes. SAFER lets you search by USDOT number, MC/MX number or company name.
What does NOT AUTHORIZED mean on SAFER?
The carrier doesn't have for-hire operating authority. That's normal for private and intrastate carriers, but a for-hire interstate carrier needs active authority.
Should my door say the legal name or the DBA?
Either the legal name or a single trade name, as listed on your MCS-150. Whichever you pick, copy it exactly from SAFER.
