An assigned number sequence required by FMCSA for all interstate carriers. The FMCSA has the authority to fine and sanction unsafe interstate truck and bus companies. These numbers are used to identify potentially unsafe motor carriers when analyzing crash data. The identification number (found on the power unit, and assigned by the U.S. DOT or by a State) is a key element in the FMCSA databases for both carrier safety and regulatory purposes.
