Does FMCSA charge a fee for the biennial MCS-150 update?

No. FMCSA does not charge for the biennial update. Services that call or mail you offering to handle it for a fee are charging for their own time, not for an FMCSA requirement.

Can I keep running loads while my USDOT status shows INACTIVE?

Do not dispatch until the registration reads ACTIVE again. Brokers checking you will see the deactivation and decline the tender, and it becomes an enforcement problem if a truck is stopped. Submit the update, confirm the change on the snapshot, then dispatch.

I have an old USDOT number from a previous company. Do I need to watch it too?

Yes. A dormant number still carries a name and history that a stranger can update. If you no longer use it, mark it out of business, keep the confirmation, and check the snapshot periodically to confirm the Form Date has not changed.

Is My DOT Number Active? Why It Goes Inactive and How to Read Your Record

To check whether your DOT number is active, open the FMCSA SAFER Company Snapshot, search your USDOT number, and read the USDOT Status field. It shows ACTIVE, INACTIVE, or OUT-OF-SERVICE. Working carriers who find their registration deactivated usually missed the biennial MCS-150 update. Less often, the cause is a submission you never made, which matters if an impostor is running loads under your name.

Is My DOT Number Active, or Is My Authority Active?

These are two separate fields on the same page, and carriers mix them up. The difference between an MC number and a DOT number is covered separately. What matters here is that each can fail on its own schedule, for its own reasons.

On the Company Snapshot, read these fields in order:

USDOT Status: your safety registration. ACTIVE means FMCSA considers it current. INACTIVE means it has been deactivated. OUT-OF-SERVICE means an order is in place; the adjacent Out of Service Date field shows when.
Operating Authority Status: your MC authority. It reads AUTHORIZED FOR Property (or similar), NOT AUTHORIZED, or OUT-OF-SERVICE. Your registration can be ACTIVE while this field reads NOT AUTHORIZED. You are registered but not allowed to haul regulated freight for hire across state lines.
MCS-150 Form Date: when the last MCS-150 was submitted. Most carriers never look at it, and it tells you the most.
Phone, Physical Address, Mailing Address: what brokers see when they check you. If the listed number is not yours, every broker who calls to confirm a load reaches a stranger.
Power Units and Drivers: the counts you reported. A jump you did not report means a third party submitted an update.

On the authority side, the Licensing and Insurance page shows whether your liability proof (BMC-91X) and process agent designation (BOC-3) are on file and whether any revocation is pending. Cargo insurance does not appear there; FMCSA does not collect it. Pull up your snapshot now, before you need it. Write down the Form Date and contact number exactly as shown, so you have a baseline to compare against later.

Why a DOT Number Goes Inactive

Deactivation is never random. Behind it is always a submission, or a missing one.

The missed biennial update

Every USDOT number holder must submit an MCS-150 update every two years, even if nothing changed. The last digit of your number sets the month: 1 is January, 2 is February, through 9 for September and 0 for October. The second-to-last digit sets the year: odd means odd-numbered years, even means even-numbered years. A carrier whose number ends in 47 updates in July of even years. Miss that window and FMCSA can deactivate the number. The snapshot will show INACTIVE, and the Form Date will be more than two years old, which confirms the cause.

A deactivation request

An MCS-150 can be submitted with the reason marked as out of business, which flips the registration to INACTIVE. If you closed a prior entity or sold equipment and a staff member sent it in, that explains it. If nobody in your company did, treat it as a fraud signal, covered below.

Out-of-service orders

OUT-OF-SERVICE is not the same as deactivation. It follows an enforcement action: a failed new entrant safety audit, an unsatisfactory safety rating, unpaid civil penalties, or an imminent hazard order. The Out of Service Date field will be populated, and FMCSA will normally have sent correspondence to the mailing address on file. If that address is not yours, you may never have seen the letter.

Authority problems that look like a DOT problem

When your insurer cancels the BMC-91X, FMCSA starts revoking your operating authority. Without a BOC-3, authority cannot be granted or kept. In both cases the registration can still read ACTIVE while Operating Authority Status turns NOT AUTHORIZED, and a broker running a quick check sees a carrier that cannot be tendered. If something changed and you do not know why, compare the Form Date against your own submission records first. It tells you whether the change came from your side or a third party's.

When the Snapshot Changed and You Did Not Change It

This pattern matters if your MC number and load board account are being impersonated. Industry reports indicate that hijackers submit MCS-150 updates on legitimate carriers' registrations to replace the phone number, email, and sometimes the mailing address with their own. The entry still carries your name, your DOT number, and your safety history. Only the contact fields are theirs.

From your side, the signs are usually indirect. A broker you have never worked with calls asking where a load is. Your factoring company asks about an invoice you did not submit. Confirmation calls stop, because brokers now dial the number on the snapshot. When you finally look, the Form Date is recent and unexplained, and the contact line is one you do not recognize.

The same mechanism explains some deactivation surprises. A fraudulent update marked out of business shuts down your number while the impostor works under a different identity. Or a dormant number you stopped using gets updated and reactivated by a stranger. If you hold a second USDOT number from an old entity, check it too. If the snapshot shows a change you did not make, take a dated screenshot of the full page before correcting anything. Once you submit a correction, the fraudulent version is overwritten on the public page.

Building the Paper Trail That Shows It Was Not You

When a broker or shipper says a load was picked up under your MC number and never delivered, the question is not whether your number is active. It is whether you can show which contact details belonged to you, and when. The FMCSA page is one piece; the rest is what you keep. The steps for someone hauling loads under your MC number cover reporting. This is the evidence that supports it.

Your own submission history. Keep the confirmation for every MCS-150 you send, noting when it went in. A snapshot Form Date that matches none of your confirmations is evidence the update was not yours.
Dated snapshots. Save a copy of your Company Snapshot and L&I page each month and after every update. A series showing your number in March and a stranger's in May fixes the window of the change.
Your phone records. If the registered number was changed, your bill shows that brokers stopped calling your real line. That counts when a broker claims it called the registered carrier to confirm.
Your ELD and dispatch logs. On the days of the disputed load, your trucks were somewhere. ELD location data showing your units on other lanes is direct proof the load was not on your equipment.
Your insurance agent's certificate. The certificate your agent issues lists your insured units by VIN. If the truck that picked up the load is not on it, that is a second independent source.

If the impersonation came through your load board login rather than the FMCSA registration, the steps after a load board account hack apply alongside these. Send the broker who contacted you a short package: the dated snapshot showing the altered field, your confirmation history, and ELD positions for your units on that day. One email replaces a week of calls.

Getting Reactivated Without Opening a New Gap

If the cause is a missed biennial update, submit the MCS-150 with current information through FMCSA's registration system. First, check every contact field against what you actually use: company phone, email, physical address, mailing address. A reactivation that carries over a hijacker's number returns you to ACTIVE with a stranger still taking broker calls.

Afterward, recheck the snapshot over the following days; updates do not always appear on the public page at once. When it shows, confirm three things: USDOT Status reads ACTIVE, the Form Date matches when you submitted, and the contact number is yours. Then check Operating Authority Status separately. If it reads NOT AUTHORIZED, reactivating the DOT number did not fix it. Your insurer needs to resubmit the BMC-91X, or your process agent the BOC-3.

If the cause was fraud, submit your corrected MCS-150 and report the identity theft to FMCSA through its National Consumer Complaint Database. State when the unauthorized change appeared and attach your screenshots. Once your registration changes, expect calls from third-party compliance services offering to handle reactivation for a fee; you can submit the MCS-150 directly. The day you reactivate, put your next biennial due month on the office calendar with a reminder a month ahead. Add a monthly check of the snapshot's contact and Form Date fields, so the next unauthorized change is caught in weeks, not when a broker calls about a missing load.
