Department of Transportation Codes- Most recently updated February 2011
|Date Published||June 14, 2011|
This list has never been published in its entirety. The most comprehensive report of department of transportation codes available.
Data are sorted three ways -- alphanumerically by code; alphabetically by company to which each plant is assigned; and cross-referenced to show the top 20+ companies' plants grouped regionally. The data include information on the status/history of plants no longer in operation but which still have an active DOT code.
