MCS-150 Service

The Motor Carrier Identification Report (MCS-150) must be filed biennially (every two years) by all motor carriers operating commercial motor vehicles as defined in §390.5, and intermodal equipment providers operating in interstate commerce. Old or incorrect MCS-150 information can have serious consequences for your business and your Unsafe Driving and Crash BASIC scores.


Avoid the consequences — and the hassles — by letting us handle the filing for you!

MCS-150 Biennial Filing Schedule 

The biennial filing schedule is determined by your USDOT number. If the next-to-last digit of your USDOT number is odd, your update must be filed in every odd-numbered calendar year. If the next-to-last digit of your USDOT number is even, your update must be filed in every even-numbered calendar year. The last digit of your USDOT number determines the month to file in. Use this chart to determine when during the year you need to file:


If your USDOT number ends in: Must file by the last day of:
1 January
2 February
3 March
4 April
5 May
6 June
7 July
8 August
9 September
0 October


A carrier may also submit an update at any other time but then must also file the scheduled biennial updates

Frequently Asked Questions

The definition in §390.5 refers to a vehicle used on a highway, in interstate commerce, that meets any one of the following criteria:

  • Has a gross vehicle weight rating (GVWR) or gross combination weight rating (GCWR), or gross vehicle weight (GVW) or gross combination weight (GCW) of 10,001 pounds or more, whichever is greater;

  • is designed to transport more than 8 passengers (including the driver) for compensation;

  • is designed to transport more than 15 passengers (including the driver), and is not used to transport passengers for compensation; or

  • is transporting hazardous materials in quantities requiring the vehicle to be placarded.

There are two other MCS-150 forms, the MCS-150B and the MCS-150C, that are to be used only in certain circumstances. The MCS-150B is the combination Motor Carrier Identification Report and FMCSA Safety Permit Application. The MCS-150B is required instead of the MCS-150 only if an intrastate or interstate carrier is transporting the type and quantity of hazardous materials listed in 49 CFR §385.403 that requires a Hazardous Material Safety Permit (HMSP).


The MCS-150C Intermodal Equipment Provider Identification Report is required for intermodal equipment providers subject to the Federal Motor Carrier Safety Regulations (FMCSRs). An intermodal equipment

provider supplies intermodal equipment, such as chassis and containers, to a carrier.

No, the FMCSA will not contact you via a third-party for payment of your MCS-150. Read more about companies posing as governement agencies.
