If you do not have access to a tracking number, you can still track your shipments with Alternate Reference Tracking. With Alternate Reference Tracking, you can track your shipments using reference numbers already assigned to a shipment. You can either track with or without an account number. Note: Only unique matches will be displayed when tracking by reference without an account number. If multiple results are found for the same reference number, you must select a FedEx service before clicking Resubmit all. If a unique match cannot be found, you will be prompted to enter the account number. You can also track packages without a tracking number using FedEx InSight®. FedEx InSight is a value-added service that can provide eligible customers with a new level of visibility. Learn more about FedEx InSight.
