AAR Railroad Reporting Marks

An AAR (Association of American Railroads) reporting mark is two to four letters that uniquely identifies the owner of a piece of railroad rolling stock. The reporting mark is generally derived from the assigned company's initials. All cars in interchange service must be labeled with a reporting mark.

Please note the following naming conventions:

Marks that end in X are assigned to railcar owners that are not common carrier railroads. These may include private car owners, leasing companies, and railroad museums.
Marks that end in U are assigned to container owners for use on intermodal containers.
Marks that end in Z are assigned to trailer owners for use on container trailers/chassis.
Marks that end in any other letter are assigned to common carrier railroads for use on railroad equipment in interchange service.
