Why Is Everyone Calling Me After I Got My MC Number?

Because your phone number is a public record now, and has been since the second you hit submit. Nothing was hacked and nobody sold you out. FMCSA publishes the registration data you filed, anyone can download it, and the companies that buy it call new authorities first. FMCSA's own guidance on the problem says these outfits often contact new carriers within minutes after completing online transactions with FMCSA. Minutes is not hyperbole in that sentence.

Where they got your number

You filled out a registration application. Since May 14, 2026 that happens in Motus, FMCSA's new registration system, behind a Login.gov profile. The system is new. What happens to the data is not. Your company name, address, phone, fleet size and commodities go into FMCSA's census record, and FMCSA publishes that census through its open data program at no charge to the public.

So there is no single list to get off. There are hundreds, all built from the same file, all refreshed on a schedule. FMCSA says the quiet part out loud: your basic carrier information is publicly available, and the services these companies offer are neither authorized nor sanctioned by FMCSA.

It also explains the second wave, two years in. Every time you touch your registration the date on that record changes, and a date is the easiest field in the world to sort by.

The Do Not Call list will not save you, and two things still might

The National Do Not Call Registry runs on the FTC's Telemarketing Sales Rule, and 16 CFR 310.6(b)(7) exempts telephone calls between a telemarketer and any business to induce the purchase of goods or services. A call to your company is a business call. The rule that powers the registry steps out of the way before you get to argue about it.

Two things survive that. Register your cell anyway is the first. FMCSA tells carriers to do exactly that, because most owner-operators put a personal cell down as the company number, and the FCC treats a wireless number on the registry as presumptively residential. The presumption can be rebutted, and how publicly you hold the line out as a business number is one of the factors courts weigh. It is free and takes under a minute at donotcall.gov.

The second has teeth. 47 U.S.C. 227(b)(1)(A)(iii) bans autodialed and prerecorded calls to a cell without prior express consent, and it does not care whether that cell is a business line or a kitchen phone. 227(b)(3) puts $500 on each violating call, up to $1,500 if it was willful or knowing, and each call counts separately. A recording that speaks before a human does is a legally different animal from a person dialing you, and most of what buries a new authority is recordings.

Keep a log from today. Date, time, the number on the screen, the company name they gave, and whether a recording talked first. That last column is the whole case, and it costs 10 seconds a call.

What is actually required, so you can hear the difference

• The biennial update. 49 CFR 390.19T(b) has you refile the MCS-150 every 24 months, in the month matching the last digit of your USDOT number, in an odd-numbered year if the next-to-last digit is odd. Free at FMCSA. Skip it and 390.19T(b)(4) allows deactivation of the number.
• UCR. Real, and not FMCSA's program. The fee is set by federal rule, the plan is run by the states, and you file it at ucr.gov. For 0 to 2 vehicles it was $46 for 2026, and 49 CFR 367.50 sets it at $55 for 2027 and after, effective October 1, 2026.
• BOC-3. 49 CFR 366.4 has you designate process agents for all 48 contiguous states and DC. A blanket agent files it once, and FMCSA publishes a process agent list for free.
• A drug and alcohol testing program, if you hold a CDL and drive a CMV. That one is at nrbcarriergroup.com/learn/do-i-need-a-drug-and-alcohol-program-if-im-the-only-driver.
• Supervisor training, only if you supervise CDL drivers. 49 CFR 382.603 is 60 minutes on alcohol misuse plus 60 on controlled substances, one time, for that supervisor's career. FMCSA certifies no trainers and pre-approves no curriculum, so nobody selling it is FMCSA approved.

Notice what is missing. Not one of those requires a third party to file it for you. FMCSA's guidance allows that vendors can provide real value, then says plainly that using a service provider is not required and that the government endorses none of them.

Four tells, straight from FMCSA

• It does not use PayPal. One mass emailed solicitation was a rewritten Biennial Update notice, on FMCSA letterhead, with PayPal links pointed at a fraudulent company.
• Its officials do not ask for banking or credit card information by telephone. Not for a filing, not for a penalty, not once.
• Caller ID reading DOT or FMCSA proves nothing. Spoofing is trivial, and spoofed IDs get used specifically to disarm you. The Truth in Caller ID Act carries up to $10,000 per violation and has stopped nobody.
• Read the small print. A legitimate vendor's mailer says on it that the company is private and not affiliated with USDOT or FMCSA. A fraudulent one buries that or leaves it off.

Pretending to be an officer or employee acting under the authority of the United States in order to demand money or a document is 18 U.S.C. 912: a fine and up to 3 years. That is the line between an aggressive vendor and a federal crime, and it gets crossed on new carriers more than it should.

When in doubt, take the caller's name and a callback number, hang up, and call FMCSA's information line at 1-800-832-5660. To report one, the DOT Office of Inspector General hotline is oig.dot.gov/hotline or (800) 424-9071.

What to do this week

• Put the cell you registered with on donotcall.gov. Free, under a minute, and it is FMCSA's own advice to carriers.
• Give up nothing on an inbound call. No DOT number confirmation, no EIN, no card, no routing number. A real vendor survives you hanging up and calling back.
• Start the call log. It is worth $500 a call if a robocall pattern turns up in it.
• Write your own deadline list down once. After that, every call either matches a date you already have or it does not, and that is the entire filter.

The list is the filter

The pitch works because a new authority does not yet know its own dates, so every invented deadline sounds plausible and every real one sounds like a threat. Write the dates down and the wave turns into noise you can let ring.

Run your USDOT number through nrbcarriergroup.com/checkup and it builds that calendar: your biennial month, your IFTA quarters, your 2290, your UCR, and your new entrant audit window if you give it your authority month. Free, no signup, and the number never leaves your browser. The order to do things in is at nrbcarriergroup.com/learn/what-to-do-after-you-get-your-mc-number, and your own biennial due date is worked out at nrbcarriergroup.com/learn/when-is-my-mcs-150-due. If you would rather those dates sat next to your loads and documents than on a sticky note, that is what our app does. The basics are free.
