This number comes from the Memphis FedEx hub. When employees call out from pretty much any of the hub's landlines, they show up under this number on caller id. I found this out the other day when my husband tried to call me from his desk (he always calls from his cell, but it had gone dead), & I didn't answer bc I didn't recognize the number. He left a msg, & I called back on his direct line. He said he has no idea why they all go through that same number.
