Form MCS-150 and Instructions - Motor Carrier Identification Report

About this Form

The Federal Motor Carrier Safety Administration (FMCSA) registration process requires that companies define the type of business operation (Motor Carrier, Broker, Shipper, Freight Forwarder and/or Cargo Tank Facility) that they plan to establish. FMCSA’s responsibilities include monitoring and enforcing compliance with the Federal Motor Carrier Safety Regulations (FMCSR) and the Hazardous Materials Regulations (HMR) governing both safety and financial responsibility.

The Agency’s focus on both concerns is reflected in the dual path of its current registration process. Companies may find that they are subject to both registration requirements - USDOT Number (Forms MCS-150 and MCS-150B) - and Interstate Operating Authority (Forms OP-1, OP-1(P), OP-1(FF), OP-1(MX), or OP-2).

We encourage applicants to register onlineFor applicants without Internet access, FMCSA can mail instructions, forms, and other materials designed to assist in the off-line registration process; call FMCSA at 1-800-832-5660.

These instructions assume that the applicant has determined that a USDOT Number is required and that the MCS-150 form must be submitted.
