2012 Roma bag Identification markings: Just the stamped BV /Made in Italy :
It's on the inside, on the black leather facing, no little tab, no metal placque like the vintage BV bags bear . This is located just above the lower edge of the facing.
There is one zip pocket in the bag. There is no marking on the zipper pull, only a leather tab. It has a small paper (Tyvek?) tag sewn onto the side seam near the bottom which reads: BOTTEGA VENETA, Made in Italy.
On its reverse is the serial number and the word AUTHENTICITY CeRTIFIED (Note all markings are in English) which should be repeated on a brown card which is included with the bag:
The final clue that you have an authentic bag: the leather fine grained, and is silky soft smooth and supple, so beautiful you could weep.
Hope this helps,
