Intermodal Driver Database (IDD)Implementation

Aug 08, 2019


On Monday, January 13, 2020 Norfolk Southern will begin using the Intermodal Association of North America’s (IANA) Intermodal Driver Database (IDD) for drayage management. Once implemented, drivers will no longer be permitted to register for terminal access at any of Norfolk Southern’s intermodal facilities. Driver’s that are not registered in IDD will not be permitted access to any Norfolk Southern intermodal facility.  

Once IDD is implemented, Motor Carriers will be responsible for adding and removing drivers from their Standard Carrier Alpha Code (SCAC) and responsible for updating driver information through their Uniform Intermodal Interchange and Facilities Access Agreement (UIIA) account. Implementing IDD has several benefits to include:

  • It provides a centralized web interface linked to the UIIA for Motor Carriers to manage and update their drivers.
  • It provides IDD subscribers with real-time access to driver information via web portal.
  • It assists in preventing fraudulent use of SCAC Codes; The IDD confirms that the driver accessing the facility is registered as an active driver under the Motor Carrier's SCAC Code.

Norfolk Southern receives IDD updates every 30 minutes so delay may incur between driver entries made in the UIIA interface and when Norfolk Southern receives the update. Additional information on IDD can be found by visiting or by clicking here.

We encourage drivers to take advantage of our ExpressNSTM Mobile Application which streamlines gate and terminal processes for our drayage community. With ExpressNSTM, drivers can verify billing, submit pre-gate information, obtain parking and pickup locations, receive electronic interchange receipts, and submit bad order information.

Drivers can download the ExpressNSTM mobile application from the App Store or Google Play Store by searching for ExpressNS. Once the application is downloaded, first-time users must click the link to register for access using their assigned Norfolk Southern driver code.
