Reference numbers for loads with an unassigned carrier

Access to reference numbers is available on a limited basis for loads without an assigned carrier. Reference Numbers controlled by Reference Number Qualifiers without a specific Carrier ID will be accessible and updatable at all times (even when a load is in OPEN operational status without an assigned carrier). Reference Numbers controlled by carrier specific Reference Number Qualifiers will be accessible and updatable only when a carrier has been assigned to the load.

Reference Numbers corresponding to the carrier-specific Reference Number Qualifiers will be removed whenever the carrier for a load is modified.

The same rules will apply to Reference Numbers at trip or booking, stop and shipment leg levels.
