USDOT Lookup Frequently Asked Questions

Is a USDOT number the same as an MC number?

No. A USDOT number tracks safety registration and vehicle operations. An MC number (Operating Authority) grants legal permission to transport regulated cargo across state lines for compensation.

Why would a USDOT record show "Not Rated" for safety?

Most carriers in the U.S. carry a "Not Rated" safety designation because FMCSA formal safety fitness audits (Satisfactory/Conditional/Unsatisfactory) are conducted on prioritized carriers. Unrated carriers still have roadside inspection and crash data recorded.
