many versions, should be same rules, but not always
I have a Fed Ex account, and I buy and ship guns and ammo. I also have a C&R FFL and can and do receive C&R guns at my house, and have shipped C&R guns direct to other C&R holders residences.
As far as ammo is concerned the shipper must apply a "Limited Quantity" sticker (NOT the old blue small arms ammunition sticker...that one is obsolete). Limited Quantity can be perfume, ammo and even some other item if I recall.
My local Fed-Ex driver is usually the same guy for the last couple years and yes....he does scan the backside of my Virginia Drivers license which has a barcode. It is a Fed-Ex rule, not the drivers choice and he has told me that by doing so he has confirmed that the package (whether gun, ammo or perfume) was delivered to the addressee in person exactly to the labels airway bill.
I don't personally have any problems with this "rule" as it protects Fed-Ex, their employees, me and my family and I don't worry about porch pirates because things are not just left on the porch.
Heck...even Lowes and Home Depot scan my drivers license after I put in my phone number for military discount so no big deal there either.
