Fedex seldomly uses the same tracking number for multiple orders (from different company orders) Example 885819010984 https://www.fedex.com/wtrk/track/?duplicateTrackingId=885819010984&trknbr=885819010984 However, Techtrack sends updates for all the packages under the tracking number ie, for the order which is not of a company too. While fetching tracking updates from Fedex, could Techtrack not cross-check the reference fields in Fedex tracking against the company's order IDs before sending the update
