Federal Requirements

Three Mandatory Registrations
for Interstate Operations

The following registrations are required by federal regulation for commercial motor carriers operating in interstate commerce. All three must be in place before regulated freight may be transported.

01
USDOT Number

A USDOT Number is the federally assigned identifier required for all commercial motor vehicle operators in interstate commerce. It is the foundational registration and a prerequisite for all subsequent FMCSA filings. Any carrier crossing state lines or transporting regulated commodities is required to register.

Mandatory — All Carriers
02
MC Operating Authority

Motor Carrier (MC) Operating Authority is required for any carrier transporting regulated commodities for compensation in interstate commerce. The application process includes liability insurance filings, BOC-3 process agent designation, and a federally mandated 25-business-day protest period before authority is officially issued.

Mandatory — For-Hire Carriers
03
FMCSA Portal Account

An active FMCSA Portal account is required to manage all USDOT registration activity, maintain accurate business records, and access federal compliance tools. The account must reflect a verified Portal Company Official and is required for the Motus system transition currently scheduled by FMCSA.

Mandatory — All USDOT Entities
