Asset Identifier

Asset Identifiers are implemented as the AssetIdentifier class. An AssetIdentifier uniquely identifies an asset (vehicle or trailer) within the system. The attributes of an AssetIdentifier are:








A string of maximum length 4 that contains the Standard Carrier Alpha Code (SCAC) for the carrier that owns this vehicle or trailer. SCACs are assigned by the National Motor Freight Traffic Association (NMFTA). SCACs are fully implemented for trailers.

SCACs are not currently supported for vehicles in QTRACS/Portal or Performance Monitoring. QTRACS and Performance Monitoring web services will return this value as blanks. This value should be set to all blanks when using the AssetIdentifier as an input parameter to QTRACS and Performance Monitoring web services.


A string of maximum length 10 that contains the identifier of the vehicle or trailer. This is usually set to the value of the tractor or trailer decal. Along with the SCAC, this value serves to uniquely define the vehicle or trailer across all companies in the Services Portal system.
