What to do after your MC number is approved

Your MC number is active. Here is what FMCSA and the states expect in the first month, in the order that keeps you legal on the road, with the official page for each filing.

The first week

1. Confirm the grant and your filings in SAFER and L&I. Active authority, insurance on file, BOC-3 on file. Keep a screenshot: brokers and shippers will ask.
2. Register for UCR. Required for interstate carriers; the fee depends on fleet size ($55 for 0-2 vehicles, $167 for 3-5 vehicles, $333 for 6-20 vehicles for the 2027 registration year). File only at the official site; copycat sites charge more.
3. IRP plates and an IFTA license from your base state if you cross state lines with a vehicle over 26,000 lbs. Allow a week or two; you cannot run interstate without them.
4. Register in the Drug and Alcohol Clearinghouse and join a testing consortium if you or your drivers hold a CDL. The Clearinghouse query and the pre-employment test both have to happen before the first dispatch, including for an owner-operator driving their own truck.

The first month

• Driver qualification file for every driver, yourself included (49 CFR 391.51): application, three-year MVR, road test or CDL copy, medical certificate from a National Registry examiner.
• ELD and hours-of-service records unless you qualify for the short-haul exemption. Keep supporting documents for six months.
• Vehicle maintenance file: inspection, repair and annual inspection records per truck.
• Accident register, even while it is empty.
• MCS-150 biennial update on your schedule (the last digit of your USDOT number sets the month). A late update deactivates the USDOT number.

The New Entrant Safety Audit

FMCSA schedules a New Entrant Safety Audit within 12 months of the grant and monitors new carriers for 18 months. The audit checks the files above. Carriers that cannot produce a drug and alcohol program, driver qualification files or hours-of-service records fail it, and a failed audit can revoke the new registration. The free checklist below shows your audit window and the items FMCSA will ask for.

What repeats every year

UCR renews every year (registration opens October 1 for the following year). IFTA returns are quarterly. IRP renews with your base state. The MCS-150 is every two years. Insurance renews on its policy date, and a lapse cancels the FMCSA filing, which suspends the authority after the notice period.

Questions

I am an owner-operator with one truck. Does all of this apply to me?

Yes. The driver qualification file, Clearinghouse registration, drug and alcohol testing, ELD rules and the new entrant audit apply to a one-truck company exactly as they do to a fleet. The audit asks for the same files.

Do I need UCR if I only run in one state?

Intrastate-only carriers are not subject to UCR. Interstate carriers, brokers and freight forwarders register every year, and the fee is by fleet size.

How do I know my MCS-150 due date?

FMCSA sets it from your USDOT number: the last digit gives the month and the second-to-last digit gives odd or even years. Enter your USDOT number below and the checklist shows the next due date.
