North American Intermodal Facilities Directory

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.

Following are some tips to enhance your viewing experience. To view a list of up to 500 intermodal facilities in a geographic area, click on the Key icon in the upper right corner and zoom in to that area of the map. To locate an intermodal facility by name, enter the name in the search box at top center. To view information about a specific facility, click on its Yellow, Red or Blue Pin icon. To filter by intermodal facility type or find routing or directions, click the Tool icon in the upper left.
