Biennial update scams: how to spot them

FMCSA does not charge for the MCS-150 biennial update. Letters and emails that look official, threaten fines and ask you to pay to file are selling a service, and some are outright scams. File it yourself for free in Motus.

Warning signs

Trade press and state agencies have warned carriers about these messages for years, including the Wisconsin DOT together with FMCSA.

How to check safely

  1. Check your real due date. Look up your USDOT number. If you aren't due, a message saying you are is a red flag.
  2. Check the official record. Search your number in Motus Public Search.
  3. File it yourself if you're due. It takes a few minutes in Motus once you're logged in. See the step-by-step guide.

Questions

Is it illegal to charge for filing the MCS-150?

Filing services can legally charge for doing the work for you. The problem is messages that look like they come from FMCSA, threaten fines, or imply the fee is required.

What should I do with a suspicious letter or email?

Don't use its links or phone numbers. Go to motus.dot.gov yourself, or call FMCSA at 1-800-832-5660 using the number from FMCSA's own site.

I already paid. What now?

Check in Motus whether an update was actually filed. If you believe you were defrauded, contact your bank or card issuer, and report it to the FTC at reportfraud.ftc.gov.
