MCS-150 Biennial Update

Help preparing a USDOT biennial update or record correction.

How we can help

Keeping a USDOT record current is an important compliance task. We help organize the company, operation, mileage, and vehicle information needed for an MCS-150 update.

What the service includes

  • Review of information needed for the update
  • Preparation checklist for operation and mileage details
  • Filing assistance for the applicable update
  • Guidance on confirming the public record

Information to prepare

USDOT number, legal business name, company-official details, current mileage, operation classification, and power-unit information as applicable.

Important: Motor Carrier Compliance is a private filing assistance service, not FMCSA or a government agency. Filing assistance does not guarantee approval, agency processing times, or a particular outcome. Government fees, if applicable, are separate.

Frequently asked questions

How quickly can this be completed?

Timing depends on the information provided and the relevant agency's processing. We can explain the expected steps after reviewing your situation.

Does submitting a filing guarantee approval?

No. The relevant agency makes eligibility and approval decisions. We help with preparation and filing, but cannot guarantee an outcome.
