The interstate moving industry in America is regulated by the Federal Motor Carrier Safety Administration (FMCSA), part of the United States Department of Transportation. Only a small staff (fewer than 20 people) is available to patrol hundreds of moving companies, making enforcement difficult. Furthermore, in the United States, there are in most cases no regulations that clearly qualify moving companies as "reliable", and thus such scams are relatively common. Moving companies can provide and often display a Department of Transportation (DOT) license.
