When I called to hold a package at Fed Ex the automated lady told me it's not available and that my package was headed to my zip code at the moment. I was just wondering if anyone knows if I have to be there to sign for it or not? Idk what "indirect signature required" means? The question mark next to it says I can can leave a Fed Ex door tag authorizing release of the package without anyone present. Do I need to go to Fed Ex to get a door tag??
