Railinc Company ID

Railinc uses company identifiers. Valid identifiers are an AAR assigned reporting mark (ABCX) or a Railinc assigned alphanumeric identifier. Companies that do not have an assigned company ID must request one. This company identification will be an alphanumeric ID (S001). There is a one-time setup charge for registering a company ID with Railinc. This identifier is unique and once established may be used to access other Railinc systems.
