Terry,
I don't have a 3A Parts Manual (PM) but my 3B PM has a separate group,
GROUP 28-03 -- LICENSE TAG BRACKETS
640745 Bracket, license tag, assembly 1
and hex bolts, lockwashers and nuts 5/16"-24 x 7/8" 2/ea
-to attach to the front bumper.
I dug around using the part number on the 2A Parts Database and found they have 2 locations for the same bracket:
32-2 and 15-10. Here:

That makes it sound like to me at a minimum an accessory. I can't say that all jeeps came with them out of the factory or were added after the dealer got them.
