The white rectangular barcode sticker on top of the Federal Express Priority sticker shows that it went through the FedEx hub. The hub did three levels of sorting on all packages, based on the Zipcode. In the primary sort, the Zipcode was keyed in, which action generated this sticker. The values on the sticker were used in the secondary and tertiary sorts to get the package on the right plane back out of Memphis. It won't tell you much beyond maybe the recipient zipcode.
