IANA's North American Intermodal Facilities Directory identifies pertinent information for terminals, ramps, container yards and depots in the United States and Canada, including specific geographic locations. The directory comprises information maintained by IANA, as part of its administration of the Driver Vehicle Inspection Reporting (DVIR) service. IANA maintains a list of these intermodal facilities along with managing the assignment of unique codes for each location to ensure routing of the Driver Vehicle Inspection Reports to the proper facility and maintenance & repair vendor as required by the Federal Motor Carrier Safety Administration.
